A practical nurse is preparing to administer 10 units of regular insulin and 20 units of NPH insulin subcutaneously to a client with diabetes mellitus. Arrange the steps for preparing the mixed insulin dose in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is to roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, draw the regular insulin, and finally draw the NPH insulin.

The correct sequence for mixing insulins follows the standard 'clear before cloudy' principle to prevent contaminating the fast-acting (clear) insulin with the intermediate-acting (cloudy) insulin. First, the NPH (cloudy) vial is gently rolled between the palms to mix the suspension without creating bubbles. Next, air equal to the prescribed dose is injected into the NPH vial to prevent a vacuum, and the needle is immediately removed. Then, air equal to the prescribed dose is injected into the regular (clear) insulin vial, and the needle is left in place. The vial is inverted to draw the regular insulin first. Finally, the needle is inserted back into the NPH vial to gently draw the prescribed dose, bringing the total volume in the syringe to the combined ordered amount.

Step-by-Step Solution

Roll the NPH insulin vial.

The cloudy insulin suspension is thoroughly mixed without forming air bubbles.

NPH is a suspension where particles settle at the bottom. Rolling ensures an accurate dose, whereas shaking creates bubbles that alter the drawn volume.

Inject 20 units of air into the NPH insulin vial.

Pressure is equalized inside the NPH vial.

Injecting air prevents a vacuum from forming. The needle is withdrawn without touching the fluid to keep the needle free of intermediate-acting insulin.

Inject 10 units of air into the regular insulin vial.

Pressure is equalized inside the regular insulin vial.

Air equalizes pressure to make drawing easier. The needle is left inside to immediately begin drawing the regular insulin.

Withdraw 10 units of regular insulin.

The syringe contains exactly 10 units of clear regular insulin.

Clear insulin must be drawn first to prevent accidental contamination of the rapid-acting insulin vial with intermediate-acting NPH insulin.

Withdraw 20 units of NPH insulin.

The syringe contains a total combined volume of 30 units of insulin.

NPH is drawn last. Careful withdrawal is required because any excess cannot be pushed back into the vial without contaminating it with regular insulin.

Question 1082Question →

A practical nurse is caring for a client who is 12 hours postoperative following a total thyroidectomy. The client reports a "tight, tingling" sensation around their mouth and in their fingers. The client's vital signs are: temperature 98.8°F (37.1°C), blood pressure 132/84 mmHg, heart rate 116 beats/min, and respiratory rate 24 breaths/min. While describing their symptoms, the client's voice is noticeably hoarse and has developed a high-pitched, crowing sound. Which action should the practical nurse take first?

Remain at the bedside, ensure the emergency tracheostomy kit is immediately accessible, and urgently notify the registered nurse.

Place the client in a flat, supine position to prevent tension on the cervical incision and page the healthcare provider.

Attempt to elicit Trousseau's sign using a blood pressure cuff and prepare to administer the prescribed oral calcium supplement.

Reassure the client that perioral tingling is a common expected finding, encourage them to rest their voice, and recheck vital signs in 30 minutes.

Show answer & explanation

Answer: Remain at the bedside, ensure the emergency tracheostomy kit is immediately accessible, and urgently notify the registered nurse.

Answer

Remain at the bedside, ensure the emergency tracheostomy kit is immediately accessible, and urgently notify the registered nurse.

The correct action prioritizes airway patency and immediate clinical escalation. A high-pitched, crowing sound (stridor) combined with hoarseness and signs of hypocalcemia (tingling/tetany) indicates impending airway obstruction due to laryngeal edema or laryngospasm. The practical nurse must stay with the client to monitor for complete obstruction, prepare for an emergency surgical airway, and immediately notify the registered nurse for advanced intervention.

Step-by-Step Solution

Analyze the clinical findings presented in the scenario.

The client has perioral and extremity tingling (signs of hypocalcemia/tetany), tachycardia, tachypnea, hoarseness, and a high-pitched crowing sound (stridor).

Identifying the physiological meaning of the symptoms determines the severity of the complication.

Correlate the findings with complications specific to a total thyroidectomy.

The findings indicate damage to or removal of the parathyroid glands (causing hypocalcemia/tetany) and laryngeal nerve damage or severe cervical edema (causing hoarseness and stridor).

Understanding postoperative risks guides the nurse toward anticipating life-threatening events.

Prioritize the complications using the ABC (Airway, Breathing, Circulation) framework.

The high-pitched crowing sound (stridor) indicates a narrowing, obstructed airway, which is an immediate, life-threatening emergency that takes precedence over circulating calcium levels.

Airway compromise will lead to respiratory arrest much faster than an uncorrected electrolyte imbalance.

Determine the safest immediate action within the practical nurse's scope of practice.

The practical nurse must not leave the client, must ensure emergency airway equipment (tracheostomy kit) is ready, and must escalate immediately to the supervising RN.

Independent LPN actions focus on immediate safety and escalation when a patient requires interventions beyond the LPN scope (e.g., emergency intubation or IV calcium administration).

Question 1083Question →

At the beginning of the day shift, the practical nurse (PN) assumes care for a 58-year-old client admitted with hypertension and type 2 diabetes mellitus. The provider's orders include an intravenous (IV) push dose of furosemide, oral metoprolol, and subcutaneous regular insulin. Current morning assessment reveals a blood pressure of $138/82\text{ mmHg}$ and a capillary blood glucose of $185\text{ mg/dL}$ . Which of the following actions by the PN are appropriate? Select all that apply.

Select all that apply

Verify the client's name and date of birth against the medication administration record.

Assess the client's apical pulse rate prior to administering the metoprolol.

Rotate the injection site for the subcutaneous regular insulin administration.

Administer the prescribed intravenous (IV) push furosemide over 2 minutes.

Scan the medication barcodes into the electronic health record after the client swallows the pills.

Show answer & explanation

Answer: Verify the client's name and date of birth against the medication administration record.; Assess the client's apical pulse rate prior to administering the metoprolol.; Rotate the injection site for the subcutaneous regular insulin administration.

Answer

The appropriate actions are to verify the client's name and date of birth, assess the apical pulse before giving metoprolol, and rotate the insulin injection site.

Safe pharmacological therapy requires the practical nurse to operate within their defined scope of practice while strictly adhering to safety protocols. This includes verifying at least two client identifiers, assessing vital parameters such as the apical pulse before administering beta-blockers, and utilizing proper administration techniques like rotating subcutaneous injection sites.

Step-by-Step Solution

Analyze the client's prescribed medications in the context of the practical nurse (PN) scope of practice.

The PN can safely administer the oral metoprolol and subcutaneous insulin, but the IV push furosemide requires a registered nurse.

Identifying tasks that fall outside the PN scope prevents unsafe practice and inappropriate task acceptance.

Evaluate each planned action for adherence to the rights of medication administration.

Verifying two client identifiers before administration is correct, but scanning barcodes after the client swallows the pills bypasses a critical pre-administration safety check.

Following strict medication administration rights reduces the risk of adverse errors.

Determine the necessary pre-administration clinical assessments and techniques for the specific medications.

Checking the apical pulse is necessary before giving a beta-blocker, and rotating sites is necessary for insulin.

Medication-specific assessments and techniques ensure therapeutic safety and efficacy.

Question 1084Question →

A licensed practical nurse (LPN) is planning care for an assigned adult client who was admitted with acute pyelonephritis and has a history of chronic kidney disease. The client is receiving continuous intravenous fluids and scheduled antibiotics. Which of the following clinical decisions by the nurse demonstrate appropriate reduction of risk potential? Select all that apply.

Select all that apply

Immediately notify the supervising registered nurse that the client's morning serum creatinine has increased from a baseline of

1.2\text{ mg/dL}

2.6\text{ mg/dL}

Administer the prescribed intravenous push ondansetron to treat the client's morning nausea and prevent potential aspiration.

Hold the scheduled oral potassium chloride supplement due to a morning serum potassium level of

5.3\text{ mEq/L}

and alert the healthcare provider.

Document a morning blood pressure of

96/58\text{ mmHg}

and a heart rate of

110\text{ bpm}

as expected responses to infection, and recheck at the next scheduled interval.

Initiate strict measurement of fluid intake and output, and immediately report a cumulative urine volume of

60\text{ mL}

over the previous

3\text{ hours}

Detail the potential complications of an upcoming cystoscopy procedure to the client to verify full comprehension before witnessing the consent form.

Show answer & explanation

Answer: Immediately notify the supervising registered nurse that the client's morning serum creatinine has increased from a baseline of $1.2\text{ mg/dL}$ to $2.6\text{ mg/dL}$ .; Hold the scheduled oral potassium chloride supplement due to a morning serum potassium level of $5.3\text{ mEq/L}$ and alert the healthcare provider.; Initiate strict measurement of fluid intake and output, and immediately report a cumulative urine volume of $60\text{ mL}$ over the previous $3\text{ hours}$ .

Answer

The correct clinical decisions involve notifying the RN about the increased serum creatinine, holding the potassium supplement for an elevated potassium level, and reporting the low urine output.

The correct actions focus on recognizing critical changes in the client's condition and acting strictly within the licensed practical nurse (LPN) scope of practice to mitigate patient harm. A sudden increase in serum creatinine indicates acute kidney injury, which requires immediate notification to the registered nurse (RN) to potentially adjust antibiotic dosages. A serum potassium of

5.3\text{ mEq/L}

is elevated (hyperkalemia), so holding scheduled potassium supplements prevents dangerous cardiac complications. Finally, a urine output of

60\text{ mL}

over

3\text{ hours}

yields a rate of

20\text{ mL/hr}

, falling significantly below the minimum adequate threshold of

30\text{ mL/hr}

. This oliguria suggests worsening renal perfusion or early shock and demands immediate escalation.

Step-by-Step Solution

Analyze the serum creatinine level.

The value increased from

1.2\text{ mg/dL}

2.6\text{ mg/dL}

This signifies an acute decline in kidney function which requires immediate escalation to adjust medication dosages and prevent toxicity.

Evaluate the serum potassium level.

The morning value is

5.3\text{ mEq/L}

, which is above the normal range of

3.5-5.0\text{ mEq/L}

Administering additional potassium would induce severe hyperkalemia, threatening cardiac stability; holding it mitigates this risk.

Calculate the hourly urine output rate.

A volume of

60\text{ mL}

over

3\text{ hours}

equates to

20\text{ mL/hr}

Normal minimum urine output is

30\text{ mL/hr}

. Values below this threshold in a client with a systemic infection strongly suggest impaired organ perfusion, necessitating emergency notification.

Key Concept

Evaluating clinical data to identify emerging complications and taking actions that remain within the LPN scope of practice to mitigate harm.

Question 1085Question →

A practical nurse is providing care for a client who is 1 day postoperative following a right total hip arthroplasty using a posterior approach. The nurse is preparing to turn the client onto their unoperated left side for back care. Which action is essential for the nurse to implement to ensure client safety and comfort during this position change?

Place an abduction wedge or pillow between the client's legs before turning

Flex the client's right hip to a 100-degree angle to ease the turning process

Allow the client's right leg to cross over the midline of the bed while turning

Elevate the head of the bed to a high-Fowler's position before initiating the turn

Show answer & explanation

Answer: Place an abduction wedge or pillow between the client's legs before turning

Answer

The nurse must place an abduction wedge or pillow between the client's legs before turning to maintain proper alignment and prevent adduction.

The correct answer maintains the client's hip in an abducted, neutral position. Following a posterior approach total hip arthroplasty, the primary goals of positioning are to prevent adduction (crossing the legs), internal rotation, and hip flexion greater than 90 degrees. Using an abduction wedge or pillow between the legs before and during a turn ensures the operative leg cannot cross the midline, thereby preventing a painful and serious surgical dislocation.

Step-by-Step Solution

Identify the surgical procedure and its associated positional restrictions.

The client had a right total hip arthroplasty (posterior approach), which requires strict precautions to prevent dislocation.

Understanding the specific surgical approach dictates the safe parameters for basic care and movement.

Recall the three primary positional movements to avoid after a posterior hip arthroplasty.

The client must avoid hip flexion greater than 90 degrees, adduction (crossing the midline), and internal rotation of the affected leg.

These movements place stress on the posterior surgical capsule and can pop the femoral head out of the acetabulum.

Select the nursing intervention that actively prevents these contraindicated movements during a lateral turn.

Placing an abduction wedge keeps the legs apart, preventing adduction and maintaining neutral alignment during the turn.

An abduction pillow physically blocks the operative leg from crossing the midline of the body.

Key Concept

Proper positioning and joint precautions following a total hip arthroplasty are essential basic care measures to prevent postoperative dislocation.

Question 1086Question →

A practical nurse is assisting with the care of a client who is prescribed scheduled oral clozapine for the management of schizophrenia. During morning data collection, the client reports a new-onset sore throat and chills. The client's vital signs are blood pressure $92/58\text{ mmHg}$ , heart rate $114\text{ beats/minute}$ , respiratory rate $20\text{ breaths/minute}$ , and temperature $101.2^\circ\text{F}$ ( $38.4^\circ\text{C}$ ). The morning laboratory results indicate a white blood cell (WBC) count of $2,200/\text{mm}^3$ and an absolute neutrophil count (ANC) of $800/\text{mm}^3$ . Which of the following actions should the practical nurse take? Select all that apply.

Select all that apply

Withhold the scheduled morning dose of clozapine.

Notify the registered nurse immediately regarding the client's vital signs and laboratory results.

Implement neutropenic precautions and ensure the client is in a private room.

Document the borderline vital signs as an expected, non-urgent response to the client's elevated temperature.

Administer the scheduled clozapine dose, as abrupt discontinuation can lead to severe withdrawal symptoms.

Prepare to administer a stat dose of broad-spectrum antibiotics via direct intravenous (IV) push as prescribed.

Show answer & explanation

Answer: Withhold the scheduled morning dose of clozapine.; Notify the registered nurse immediately regarding the client's vital signs and laboratory results.; Implement neutropenic precautions and ensure the client is in a private room.

Answer

The practical nurse should withhold the scheduled dose of clozapine, notify the registered nurse immediately, and implement neutropenic precautions.

The correct answers involve recognizing that the client is experiencing agranulocytosis (a critical adverse effect of clozapine) complicated by neutropenic fever and potential early septic shock. The practical nurse must prioritize safety by withholding the offending medication to prevent further bone marrow suppression. Because the client has an absolute neutrophil count (ANC) of 800/mm³, implementing neutropenic precautions in a private room is necessary to prevent exposure to pathogens. Furthermore, the combination of a fever, tachycardia, and borderline hypotension in an immunocompromised client indicates a medical emergency; therefore, immediately escalating these findings to the registered nurse is critical.

Step-by-Step Solution

Analyze the client's laboratory results in the context of their prescribed medication.

The WBC count and ANC are critically low, indicating agranulocytosis, which is a known severe adverse effect of clozapine.

Identifying critical lab values determines if a medication is safe to administer.

Evaluate the client's vital signs and physical symptoms.

The client has a fever, sore throat, tachycardia, and hypotension, which collectively suggest neutropenic fever and impending septic shock.

Recognizing signs of sepsis early allows for prompt escalation and lifesaving interventions.

Determine the appropriate nursing interventions within the practical nurse scope of practice.

The nurse must withhold the clozapine, initiate neutropenic precautions, and urgently notify the registered nurse. Administering IV push medications must be avoided as it falls outside the practical nurse scope.

Safe practice requires acting within legal boundaries while protecting the client from immediate harm.

Key Concept

Monitoring for and responding to clozapine-induced agranulocytosis and understanding the practical nurse scope of practice in emergent situations.

Question 1087Question →

A practical nurse is preparing to administer an intramuscular injection of iron dextran using the Z-track method to an adult client. In what order should the nurse perform the following actions? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: verify client identity and don gloves, cleanse the site, displace the tissue laterally, insert the needle and inject, and finally withdraw the needle and release the skin.

The Z-track method is specifically used for irritating or staining medications like iron dextran. The practical nurse must first ensure safety by verifying the client's identity and donning gloves. After the site is cleansed, the skin and subcutaneous tissue are pulled laterally to offset the tissue layers. The medication is then injected at a 90-degree angle. Finally, the needle must be completely removed before releasing the skin. This specific sequence breaks the needle track and traps the medication deep in the muscle, preventing irritation or discoloration of subcutaneous tissues.

Step-by-Step Solution

Verify identity and don gloves.

The correct client is confirmed and standard precautions are applied.

Ensures the 'right client' is receiving the medication and protects the nurse from bloodborne pathogens.

Cleanse the ventrogluteal site.

The skin over the injection site is disinfected.

Prevents the introduction of surface microorganisms into the deep muscle tissue during needle insertion.

Displace the skin laterally.

The subcutaneous tissue is shifted over the muscle.

Creates a zigzag tissue path that will seal the needle track once released, defining the Z-track method.

Insert needle and inject.

Medication is delivered into the muscle layer.

The 90-degree angle ensures intramuscular, rather than subcutaneous, delivery of the medication.

Withdraw needle and release skin.

The displaced tissue returns to its original anatomical position.

Traps the irritating or staining medication (like iron dextran) in the muscle and prevents it from tracking up into the subcutaneous tissue.

A client who is restricted to a flat bed rest position suddenly begins experiencing active, forceful emesis. The responding practical nurse (PN) must immediately intervene to stabilize the client. In which order should the PN perform the following actions? (Arrange from first action to last)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first turn the client to the side, then suction the airway, followed by measuring respiratory vital signs, and finally notifying the registered nurse.

In any acute physiological event, the nursing process and ABC prioritization dictate that airway protection is the absolute first step. Turning a vomiting, supine client to their side uses gravity to immediately protect the airway. Only after the airway is protected and cleared should the nurse assess vital signs and report the findings.

Step-by-Step Solution

Prioritize the airway by immediately repositioning the client.

The client is moved into a side-lying (lateral) position.

According to the ABC (Airway, Breathing, Circulation) framework, establishing and protecting the airway is the highest priority. A supine client who is vomiting is at severe risk for aspiration.

Clear the immediate airway of any remaining obstructions.

The mouth and oropharynx are suctioned.

After using gravity to prevent further aspiration, removing residual emesis ensures the client can breathe without pulling fluid into the lungs.

Assess the client's physiological response to the event.

Respiratory rate and oxygen saturation are obtained.

Once the airway is safe, the nurse must assess breathing and oxygenation to determine if aspiration or hypoxia occurred during the episode.

Communicate findings to the healthcare team.

The supervising registered nurse is notified.

Escalation of care and reporting should always follow immediate life-saving interventions and the gathering of current assessment data.

A practical nurse (PN) is collecting data on a client 12 hours after a total abdominal hysterectomy. Which of the following assessment findings are considered expected, benign post-operative findings that can be safely documented without immediate escalation to the registered nurse (RN)? Select all that apply.

Select all that apply

Scant serosanguineous drainage on the surgical dressing that has remained unchanged for 4 hours.

A resting heart rate of 118 bpm and a blood pressure of 94/62 mm Hg.

Hypoactive bowel sounds auscultated in all four abdominal quadrants.

A morning laboratory report showing a hemoglobin level of 7.6 g/dL.

A reported incisional pain level of 3 on a 0 to 10 scale one hour after receiving an oral analgesic.

Sudden-onset shortness of breath and an oxygen saturation of 89% on room air.

Show answer & explanation

Answer: Scant serosanguineous drainage on the surgical dressing that has remained unchanged for 4 hours.; Hypoactive bowel sounds auscultated in all four abdominal quadrants.; A reported incisional pain level of 3 on a 0 to 10 scale one hour after receiving an oral analgesic.

Answer

The expected, benign findings are scant serosanguineous drainage on the dressing, hypoactive bowel sounds, and a controlled pain level of 3 out of 10.

In the early post-operative period (12 hours) following abdominal surgery, it is entirely expected for bowel motility to be slow (hypoactive bowel sounds), for minor, non-expanding serosanguineous drainage to be present on the dressing, and for pain to be present but manageable (3/10) with prescribed analgesics. These findings indicate a normal recovery trajectory.

Step-by-Step Solution

Analyze the client's post-operative timeline and surgical procedure.

The client is 12 hours post-total abdominal hysterectomy, a major abdominal surgery.

Establishing the timeline helps differentiate between normal early healing processes and emerging acute complications.

Evaluate each assessment finding against expected post-operative physiological responses.

Identified that scant drainage, sluggish bowel sounds, and mild pain are normal. Conversely, hypoxia, abnormal vital signs, and low hemoglobin are abnormal.

The PN must use clinical judgment to discriminate between findings that require basic monitoring versus those demanding immediate RN escalation.

Select the findings that represent benign conditions.

The scant serosanguineous drainage, hypoactive bowel sounds, and well-controlled pain level are selected.

These findings fulfill the prompt's requirement to identify safe, expected data that do not warrant urgent intervention.

Question 1090Question →

While reviewing morning laboratory reports, a practical nurse notes that a client taking daily warfarin has an International Normalized Ratio (INR) of 5.8. Which action is the priority for the nurse to take?

Document the INR value in the electronic health record and continue routine care.

Administer the scheduled morning dose of warfarin as prescribed.

Withhold any scheduled warfarin and immediately notify the registered nurse.

Independently order a repeat blood test to confirm the elevated laboratory value.

Show answer & explanation

Answer: Withhold any scheduled warfarin and immediately notify the registered nurse.

Answer

The correct action is to withhold any scheduled warfarin and immediately notify the registered nurse.

An INR of 5.8 is dangerously above the therapeutic range, indicating a severe risk for bleeding. The safest and most appropriate action within the practical nurse scope of practice is to withhold any further doses of the anticoagulant and promptly communicate the critical laboratory value to the registered nurse or healthcare provider so that medical interventions (such as administering vitamin K) can be initiated.

Step-by-Step Solution

Identify the normal therapeutic range for INR.

The typical therapeutic range for a client on warfarin is generally 2.0 to 3.0.

Understanding baseline therapeutic levels is necessary to interpret laboratory results accurately.

Analyze the client's current INR value.

The client's INR is 5.8, which is critically high.

A critically high INR indicates that the blood is clotting too slowly, severely increasing the client's risk of spontaneous bleeding.

Determine the appropriate nursing intervention within the practical nurse scope.

The nurse must withhold the medication and notify the supervising RN or provider.

Preventing harm (withholding the dose) and escalating critical findings are fundamental safety responsibilities of the practical nurse.

Show answer & explanation

Answer: Withholding a scheduled dose of oral diltiazem for a client with an apical pulse of 52 beats/minute and reporting the finding to the registered nurse (RN).; Reinforcing teaching regarding the importance of maintaining a consistent dietary intake of vitamin K for a client prescribed warfarin.; Documenting the administration of a scheduled subcutaneous enoxaparin injection immediately after safely disposing of the syringe.

Answer

The correct actions include withholding diltiazem for bradycardia, reinforcing dietary teaching for warfarin, and documenting medication administration immediately after the procedure.

The correct actions demonstrate adherence to strict medication safety and professional scope. Withholding a calcium channel blocker for bradycardia prevents cardiovascular collapse. Reinforcing previous teaching regarding dietary vitamin K and warfarin ensures therapeutic anticoagulant levels without overstepping into initial RN teaching duties. Finally, immediate documentation prevents dangerous duplicate medication errors.

Step-by-Step Solution

Evaluate each action for basic medication safety principles.

Identify that withholding a heart-rate lowering drug for bradycardia, checking proper contraindications, and timely documentation are essential safety measures.

Client safety is the primary goal; failing to identify contraindications or abnormal vital signs before administration can lead to severe adverse events.

Analyze each action against the established practical nursing scope of practice.

Determine that reinforcing teaching and administering oral/subcutaneous medications are within scope, whereas administering IV push medications and initial complex teaching are out of scope.

Nurses must operate strictly within their legal and educational boundaries to ensure competent care delivery.

Synthesize the findings to select the statements that meet both safety standards and scope constraints.

Select the options involving holding diltiazem, reinforcing warfarin education, and prompt documentation.

These actions demonstrate a comprehensive understanding of both pharmacological principles and professional nursing boundaries.

During a busy morning shift at a community health clinic, a registered nurse (RN) delegates several medication administration tasks to the practical nurse (PN). Which of the following tasks should the PN accept and perform safely?

Providing a scheduled oral opioid analgesic to a client with chronic pain after verifying their name and date of birth.

Administering a live attenuated influenza vaccine to a client who is currently receiving immunosuppressive chemotherapy.

Calculating a weight-based dose and delivering a prescribed intravenous (IV) push antibiotic to a pediatric client.

Giving a routine oral antihypertensive medication to a familiar client without checking the identification band.

Show answer & explanation

Answer: Providing a scheduled oral opioid analgesic to a client with chronic pain after verifying their name and date of birth.

Answer

The practical nurse should safely accept the task of providing a scheduled oral opioid analgesic to a client with chronic pain after properly verifying their name and date of birth.

Administering scheduled oral medications is a fundamental skill within the practical nurse's scope of practice. Furthermore, strictly verifying two client identifiers (such as name and date of birth) before administration demonstrates adherence to essential patient safety protocols.

Step-by-Step Solution

Analyze each delegated task against the practical nurse (PN) scope of practice and safety protocols.

The oral analgesic task aligns with PN scope, while the IV push antibiotic task exceeds it.

It is the PN's responsibility to refuse assignments that require RN-level interventions (like IV push medications).

Evaluate the remaining tasks for adherence to safe medication administration principles.

Checking two client identifiers is a required safety step, making the option that bypasses this step unsafe.

Bypassing identifier checks, even for familiar clients, introduces a high risk of medication error.

Review the clinical appropriateness of the medications being administered based on client conditions.

Giving a live vaccine to an immunosuppressed client is a critical contraindication.

Live vaccines can cause active infection in clients with compromised immune systems, such as those on chemotherapy.

Question 1093Question →

An assigned client with chronic heart failure is scheduled to receive morning medications at 0900. The prescriptions include oral lisinopril 10 mg, oral spironolactone 25 mg, and an oral potassium chloride 20 mEq supplement. The morning electronic health record reveals a blood pressure of 134/82 mm Hg, a heart rate of 76 beats/min, and a serum potassium level of 5.8 mEq/L (5.8 mmol/L). Based on the practical nursing scope of practice, which action is the priority?

Withhold the lisinopril, spironolactone, and potassium chloride, and immediately notify the registered nurse.

Administer the medications as prescribed, assuming an elevated potassium level is an expected compensatory response in heart failure.

Withhold the potassium chloride supplement, but independently proceed with administering the lisinopril and spironolactone.

Calculate and administer half of the prescribed potassium chloride dose to maintain electrolyte balance without causing further toxicity.

Show answer & explanation

Answer: Withhold the lisinopril, spironolactone, and potassium chloride, and immediately notify the registered nurse.

Answer

The priority action is to withhold the lisinopril, spironolactone, and potassium chloride, and immediately notify the registered nurse.

A serum potassium level of 5.8 mEq/L indicates severe hyperkalemia (normal is 3.5-5.0 mEq/L). Lisinopril is an ACE inhibitor that causes potassium retention. Spironolactone is a potassium-sparing diuretic. Administering these medications, along with a direct potassium supplement, would drastically increase the client's potassium level, placing them at immediate risk for life-threatening cardiac dysrhythmias such as ventricular fibrillation. The practical nurse must practice within their scope by withholding all three dangerous medications and immediately notifying the RN or provider for further orders.

Step-by-Step Solution

Analyze the client's laboratory data against normal reference ranges.

The serum potassium is 5.8 mEq/L, which indicates severe hyperkalemia (normal range is 3.5 to 5.0 mEq/L).

Pre-administration assessment of relevant labs is mandatory for medication safety.

Evaluate the pharmacological effects of the prescribed medications on the critical laboratory value.

Lisinopril (an ACE inhibitor), spironolactone (a potassium-sparing diuretic), and potassium chloride all increase serum potassium levels.

Administering these medications will dangerously exacerbate the hyperkalemia and risk cardiac arrest.

Determine the appropriate intervention within the practical nursing scope of practice.

The safest and legally correct action is to withhold all three contraindicated medications and immediately escalate the critical lab value to the supervising RN.

Practical nurses do not have the authority to independently alter doses or medication schedules.

Key Concept

Hyperkalemia contraindicates the administration of ACE inhibitors, potassium-sparing diuretics, and potassium supplements; the PN must withhold these and notify the RN.

Question 1094Question →

A practical nurse is monitoring a client who began receiving a packed red blood cell (PRBC) transfusion 15 minutes ago. The client suddenly reports acute lower back pain, chills, and shortness of breath. To reduce the risk of further complications, arrange the following nursing actions in the correct priority order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first stop the transfusion, then initiate a normal saline infusion with new tubing, notify the RN and provider, obtain vital signs, and finally return the blood products to the blood bank.

In the event of a suspected hemolytic transfusion reaction, nursing priorities focus on immediately halting the antigen exposure and maintaining venous access for emergency medications. Stopping the transfusion is universally the first step. Next, the line must be kept open with 0.9% sodium chloride, crucially using completely new tubing to avoid infusing the blood left in the original line. Once the immediate source of harm is stopped and access is secured, the nurse escalates to the RN and provider. Assessing vital signs and monitoring urine output follows to detect shock or renal failure. Finally, administrative and diagnostic steps, such as sending the blood bag to the lab, are completed after client stabilization.

Step-by-Step Solution

Stop the blood transfusion immediately.

Halts the infusion of potentially incompatible blood.

The absolute first priority in any suspected transfusion reaction is to prevent further exposure to the antigen, reducing the risk of a severe hemolytic reaction.

Disconnect the blood tubing and attach a new normal saline infusion line.

Maintains intravenous access without infusing remaining blood.

Using new tubing ensures the incompatible blood left in the old administration set is not inadvertently flushed into the client's circulation.

Notify the registered nurse (RN) and the healthcare provider.

Escalates the critical situation.

The RN and provider must evaluate the client immediately to prescribe emergency pharmacological interventions (e.g., epinephrine, diuretics) and provide advanced care.

Obtain a complete set of vital signs and monitor urinary output.

Assesses for systemic complications.

Hemodynamic instability (shock) and oliguria (acute kidney injury) are severe complications of a hemolytic reaction that require close monitoring.

Return the discontinued blood bag and tubing to the blood bank.

Allows for laboratory analysis.

The blood bank must analyze the remaining product and tubing to identify the exact cause of the reaction, but this is a secondary step performed after the client is stabilized.

Question 1095Question →

A licensed practical nurse (LPN) enters the room of a client who is being treated for a hemothorax and observes that the client's chest tube has been accidentally pulled completely out of the chest wall. Arrange the following nursing actions in the correct priority sequence to manage this emergency and reduce the risk of further respiratory complications.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate prevention of air entry, followed by site closure, clinical assessment, escalation of care, and preparation for medical intervention.

In the event of an accidental chest tube dislodgement from the chest wall, the primary risk is atmospheric air entering the pleural space, leading to a tension pneumothorax. The immediate priority is stopping air entry by instructing the client to perform the Valsalva maneuver, followed instantly by applying a three-sided occlusive dressing. Only after the airway and breathing mechanics are secured should the nurse perform a thorough respiratory assessment, report the findings to the RN, and prepare for medical reinsertion.

Step-by-Step Solution

Instruct the client to exhale forcefully and bear down.

Creates positive intrathoracic pressure.

Prevents atmospheric air from instantly rushing into the negative-pressure pleural space, which could cause a tension pneumothorax.

Apply a sterile, occlusive dressing taped on three sides.

Seals the chest wall defect with a one-way flutter valve.

Taping on three sides allows trapped air to escape during exhalation but prevents new air entry during inhalation.

Assess respiratory effort, lung sounds, and oxygen saturation.

Establishes the client's current physiological stability.

Provides critical clinical data to determine if the client is developing respiratory failure after the site is secured.

Notify the supervising RN and the healthcare provider.

Escalates the clinical emergency to the appropriate level of care.

The RN and provider must intervene medically; providing them with the immediate assessment data streamlines the emergency response.

Gather sterile equipment for chest tube reinsertion.

Prepares the environment for the necessary medical procedure.

Anticipating the provider's needs reduces delays in re-establishing proper pleural drainage.

Question 1096Question →

An $11$ -month-old infant is admitted with acute otitis media. The infant weighs $18$ lb $12$ oz. The primary healthcare provider prescribes amoxicillin-clavulanate $45$ mg/kg/day by mouth, in equally divided doses every $8$ hours. The pharmacy supplies amoxicillin-clavulanate oral suspension with a concentration of $200$ mg/ $5$ mL.

How many milliliters will the practical nurse administer for a single dose?
*(Record your answer to the nearest tenth. Do not include units in your answer.)*

Show answer & explanation

Answer: 3.2

Answer

3.2

The correct calculation requires converting the infant's weight to kilograms accurately (including converting ounces to a fraction of a pound), calculating the weight-based daily dose, dividing by the frequency of administration to find the individual dose, and finally converting the ordered dose to a volume based on the supplied concentration, rounding only at the final step to prevent compounding rounding errors.

Step-by-Step Solution

Convert the infant's weight from ounces to pounds.

The total weight is 18.75 lb.

Standard weight conversion is required because 16 ounces equal 1 pound.

Convert the weight from pounds to kilograms.

The infant weighs 8.5227 kg.

The medication dosage is prescribed based on body weight in kilograms.

Calculate the total daily medication dose in milligrams.

The total daily dose is 383.5227 mg.

Multiplying the infant's weight in kg by the prescribed 45 mg/kg/day yields the 24-hour dose requirement.

Determine the amount of medication required for a single dose.

A single dose is 127.8409 mg.

The medication is given every 8 hours, which equals 3 divided doses per day.

Calculate the liquid volume to administer per dose based on the pharmacy supply.

The calculated volume is 3.196 mL.

Using the desired-over-have formula with the 200 mg / 5 mL concentration determines the volume.

Round the final calculated volume to the nearest tenth.

3.2

Standard rounding rules apply; since the hundredths place is 9, round up the tenths place.

Verifying the client's name and date of birth before administering a scheduled dose of oral medication.

Immediately notifying the registered nurse (RN) when a client's morning fasting blood glucose is 42 mg/dL.

Escalating to the charge nurse when a postoperative client's heart rate gradually increases to 115 beats per minute with decreasing blood pressure.

Waiting to report a critical laboratory result of a hemoglobin level at 6.5 g/dL until the healthcare provider rounds later in the afternoon.

Assuming a blood pressure of 88/50 mm Hg is a normal, expected finding for an older adult client who just returned from surgery.

Accepting a delegated task from the RN to administer an initial dose of intravenous (IV) push morphine to a client in severe pain.

Show answer & explanation

Answer: Verifying the client's name and date of birth before administering a scheduled dose of oral medication.; Immediately notifying the registered nurse (RN) when a client's morning fasting blood glucose is 42 mg/dL.; Escalating to the charge nurse when a postoperative client's heart rate gradually increases to 115 beats per minute with decreasing blood pressure.

Answer

The correct actions include verifying two distinct client identifiers before administering medication, immediately escalating a critically low blood glucose level, and promptly reporting vital sign trends that suggest early shock.

Appropriate risk reduction requires the practical nurse to strictly follow established safety protocols (such as using two identifiers for medications) and to immediately recognize and escalate life-threatening clinical changes. A blood glucose of 42 mg/dL represents critical hypoglycemia requiring immediate treatment. A rising heart rate combined with a dropping blood pressure is a classic early indicator of hypovolemic shock or hemorrhage that must be reported to the RN immediately.

Step-by-Step Solution

Evaluate the medication safety and scope of practice actions.

Verifying two identifiers is correct. Accepting an IV push medication assignment is incorrect because it is outside the PN scope of practice.

Risk reduction requires strict adherence to medication safety protocols and legal practice boundaries.

Evaluate the laboratory value management actions.

Immediately reporting a blood glucose of 42 mg/dL is correct. Delaying the report of a 6.5 g/dL hemoglobin level is incorrect.

Both values are critical. Delaying notification of critical labs directly increases client risk.

Evaluate the vital sign assessment actions.

Reporting tachycardia with hypotension is correct. Dismissing a blood pressure of 88/50 mm Hg as normal is incorrect.

Changes in vital signs postoperatively are early indicators of hemorrhage or shock and must be escalated, never ignored.

Question 1098Question →

A practical nurse is preparing to administer morning medications to a pediatric client. The facility's barcode medication administration system is temporarily offline for maintenance. Which action demonstrates the safest practice by the nurse?

Confirm the client's identity by checking the room and bed number against the medication administration record.

Estimate the medication dosage based on the child's age rather than calculating it using the most recent weight.

Verify the client's identity by checking the identification band and asking the parent to state the child's name.

Administer a scheduled intravenous push antibiotic to ensure the client receives all morning medications on time.

Show answer & explanation

Answer: Verify the client's identity by checking the identification band and asking the parent to state the child's name.

Answer

The safest practice is to verify the client's identity by checking the identification band and asking the parent to state the child's name.

The correct action ensures the 'Right Client' by using two distinct and acceptable manual identifiers: the identification band and the parent's verbal confirmation of the name. This is a critical safety step when barcode scanning technology is unavailable.

Step-by-Step Solution

Identify the clinical challenge presented in the scenario.

The barcode medication scanner is offline, removing an automated safety check for medication administration.

Recognizing the absence of technology highlights the need for strict adherence to manual safety protocols.

Recall the Six Rights of Medication Administration.

The nurse must prioritize confirming the 'Right Client' before giving any medication.

Patient identification is the foundational step in preventing medication errors.

Determine acceptable manual identifiers for a pediatric client.

Acceptable identifiers include the client's full name, date of birth, and identification band. Verbal confirmation from a parent is appropriate for young children.

Two distinct, reliable identifiers must always be used when automated systems fail.

Evaluate the remaining options against safety protocols and scope of practice.

Room numbers are unsafe identifiers, age-based dosing is dangerous for pediatrics, and IV push medications are outside the practical nurse scope of practice.

Eliminating unsafe or out-of-scope actions confirms the correct choice.

Key Concept

Safe medication administration requires the use of at least two acceptable client identifiers (such as name and date of birth) prior to administering any medication, especially when automated systems are unavailable.

Question 1099Question →

A practical nurse (PN) is collecting data on an adult client who is receiving continuous intravenous (IV) fluid therapy. Which of the following findings should the PN identify as physiological signs of fluid volume excess (hypervolemia)? Select all that apply.

Select all that apply

Jugular vein distention

Bounding peripheral pulses

Bilateral crackles in the lung bases

Urine specific gravity of 1.032

Postural hypotension

Flat neck veins when supine

Show answer & explanation

Answer: Jugular vein distention; Bounding peripheral pulses; Bilateral crackles in the lung bases

Answer

The correct physiological signs of fluid volume excess are jugular vein distention, bounding peripheral pulses, and bilateral crackles in the lung bases.

Fluid volume excess (hypervolemia) occurs when there is an abnormal retention of water and sodium in the extracellular fluid compartment. This increased volume directly raises hydrostatic pressure in the blood vessels, leading to bounding peripheral pulses and distended jugular veins. As pressure builds in the pulmonary circulation, fluid is forced into the alveoli, resulting in respiratory manifestations such as shortness of breath and bilateral crackles upon auscultation.

Step-by-Step Solution

Analyze the client's clinical situation.

The client is receiving continuous IV fluid therapy, placing them at risk for receiving too much fluid, leading to fluid volume excess (hypervolemia).

Identifying the primary risk factor helps anticipate the specific physiological changes associated with that condition.

Recall the systemic effects of fluid volume excess.

Excess intravascular fluid increases blood pressure, engorges veins, and can lead to fluid shifting into the lungs (pulmonary edema).

Understanding the pathophysiology of fluid overload is necessary to correctly identify the associated clinical signs.

Evaluate each finding to determine if it indicates fluid excess or deficit.

Jugular vein distention, bounding pulses, and lung crackles indicate excess. A high urine specific gravity, postural hypotension, and flat neck veins indicate deficit.

Differentiating between signs of excess and deficit ensures accurate data collection and reporting.

Key Concept

Recognition of fluid volume excess (hypervolemia) involves identifying signs of increased intravascular volume and pulmonary congestion.

Question 1100Question →

An older adult client is admitted to the medical-surgical unit immediately after undergoing a diagnostic cardiac catheterization using the right femoral approach. Which action must the practical nurse (PN) implement to decrease the risk of a post-procedural hemorrhage?

Maintain the client on bed rest while keeping the right leg completely straight.

Elevate the head of the client's bed to a 60-degree angle to promote comfort.

Document a gradually rising heart rate as an expected response to the dye.

Apply a warm, moist compress directly over the right groin area.

Show answer & explanation

Answer: Maintain the client on bed rest while keeping the right leg completely straight.

Answer

Maintain the client on bed rest while keeping the right leg completely straight.

Following a femoral cardiac catheterization, the insertion site is at a high risk for arterial bleeding. Keeping the affected leg straight and maintaining bed rest prevents unnecessary pressure, flexion, and movement at the puncture site, ensuring the arterial clot remains stable and intact.

Step-by-Step Solution

Identify the procedure and its primary immediate complication risk.

The procedure is a femoral cardiac catheterization, which carries a high risk of arterial bleeding at the groin insertion site.

Understanding the procedural risks guides prioritizing the most appropriate protective nursing intervention.

Determine how physical positioning impacts the femoral artery.

Bending the hip or moving the leg puts mechanical stress on the puncture site, which can disrupt clot formation.

Maintaining the structural integrity of the newly formed clot is essential to prevent hemorrhage.

Select the nursing action that mitigates this specific risk.

Keeping the right leg entirely straight on bed rest minimizes hip flexion and protects the puncture site.

This is the standard evidence-based intervention to prevent post-catheterization bleeding.
