A practical nurse (PN) enters the room of an elderly client to administer a scheduled dose of oral morphine for chronic back pain. The PN notes that the client, who is typically alert and oriented, is now acutely confused, lethargic, and struggling to stay awake. Which of the following is the most appropriate action for the PN to take?

Administer the medication as prescribed, attributing the confusion to expected age-related cognitive changes.

Prioritize the client's chronic pain management and administer the morphine while monitoring their respiratory rate.

Withhold the medication and immediately report the client's change in mental status to the registered nurse.

Verify the client's identity using the name posted on the room door due to the client's lethargy, then administer the medication.

Show answer & explanation

Answer: Withhold the medication and immediately report the client's change in mental status to the registered nurse.

Answer

Withhold the medication and immediately report the client's change in mental status to the registered nurse.

The correct answer identifies that the client is experiencing an acute change in neurological status (lethargy and confusion). Because morphine is an opioid analgesic that can cause central nervous system and respiratory depression, giving the medication could be dangerous. The most appropriate action within the practical nurse (PN) scope of practice is to withhold the medication and immediately notify the registered nurse (RN) so a comprehensive assessment can be performed.

Step-by-Step Solution

Assess the client's current status and compare it to their baseline.

The client is experiencing acute confusion and lethargy, which represents a significant change from their typically alert baseline.

Identifying acute changes in a client's condition is a critical component of safe medication administration.

Determine the safety of administering the scheduled medication.

Morphine is a central nervous system depressant. Administering it to a lethargic and confused client increases the risk of severe respiratory depression and worsening mental status.

Opioids can exacerbate hypoxia and central nervous system depression.

Select the appropriate action within the practical nurse scope of practice.

The PN must withhold the dose and promptly escalate the finding to the registered nurse (RN) for further assessment and intervention.

An acute change in condition requires an RN-level assessment to determine the underlying cause before proceeding.

Key Concept

Monitoring for adverse pharmacological effects and adhering to the practical nurse scope of practice regarding acute changes in client condition.

Question 763Question →

A practical nurse (PN) is preparing to provide a bed bath and linen change for a client on the second post-operative day following a right-sided pneumonectomy. The client is currently resting in a semi-Fowler's position and reports mild incisional stiffness. Which action is the most appropriate for the PN to implement to safely complete these basic care tasks?

Maintain the head of the bed elevated and gently turn the client toward the right side to wash the back and replace the linens.

Carefully roll the client onto the left lateral position to relieve pressure on the surgical incision during the bath.

Lower the head of the bed completely flat so the client can be easily rolled from side to side without sheer force.

Assign the entire procedure to an unlicensed assistive personnel with instructions to closely monitor the client's oxygen saturation.

Show answer & explanation

Answer: Maintain the head of the bed elevated and gently turn the client toward the right side to wash the back and replace the linens.

Answer

The most appropriate action is to maintain the head of the bed elevated and gently turn the client toward the right side to wash the back and replace the linens.

Following a pneumonectomy, the most critical positioning principle is to place the client on their back or on the operative side (in this scenario, the right side). This ensures that the single remaining functional lung is entirely unrestricted and can expand optimally to maintain adequate gas exchange. Maintaining the head of the bed elevated further supports respiratory mechanics while safely providing basic hygiene.

Step-by-Step Solution

Identify the surgical procedure and its specific physiological implications.

The client had a right-sided pneumonectomy, meaning the right lung was completely removed and only the left lung remains functional.

Understanding the anatomy alters standard turning protocols during basic hygiene care.

Determine the correct post-operative positioning rules for a pneumonectomy.

Clients must be positioned on their back (supine) or on their operative side (right side in this case).

Positioning on the operative side ensures the fluid fills the empty surgical space and allows the remaining lung (left) to fully expand without restriction.

Evaluate the options against safe basic care principles.

Turning to the right side with the head elevated is the only safe option that maintains respiratory status while allowing access for hygiene.

It aligns with both basic comfort measures and strict post-operative safety guidelines.

Question 764Question →

An older adult client who recently suffered a mild stroke is having difficulty swallowing solid foods. The medication administration record includes a scheduled dose of enteric-coated pantoprazole. When the client requests that the pill be crushed, what is the best response by the practical nurse?

I can crush the pill and mix it with a spoonful of pudding to make it easier to swallow.

I will give you the pill with a full glass of water and have you tilt your head back to swallow.

I will contact the registered nurse to see if we can get this medication in a different form.

I can skip this dose for now and wait until your swallowing improves later today.

Show answer & explanation

Answer: I will contact the registered nurse to see if we can get this medication in a different form.

Answer

The practical nurse should explain that the medication cannot be crushed and contact the registered nurse to request an alternative formulation.

Enteric-coated medications are designed to dissolve in the alkaline environment of the intestines rather than the acidic environment of the stomach. Crushing these pills destroys the protective coating, which can lead to stomach irritation or the destruction of the medication by stomach acid. The nurse must recognize this strict contraindication and collaborate with the registered nurse or healthcare provider to obtain a safe, alternative formulation for a client experiencing dysphagia.

Step-by-Step Solution

Evaluate the medication's specific properties.

Identify that pantoprazole is prescribed as an enteric-coated tablet.

Enteric coatings are designed to protect the stomach lining from the drug or protect the drug from being destroyed by stomach acid.

Determine the safety of the client's request to crush the medication.

Conclude that crushing the pill is strictly contraindicated.

Crushing an enteric-coated pill destroys its specialized coating, which alters the absorption rate and can cause adverse effects.

Formulate a safe plan of care based on the client's dysphagia.

Notify the registered nurse or healthcare provider to request a liquid or alternative formulation.

It is within the practical nurse's scope of practice to recognize medication contraindications, advocate for client safety, and report necessary changes to the supervising nurse.

Show answer & explanation

Answer: Ask the client to state their full name and date of birth.; Compare the medication label directly with the medication administration record.; Verify the client's allergy status prior to giving the medication.

Answer

The correct actions are to ask the client to state their full name and date of birth, compare the medication label with the medication administration record, and verify the client's allergy status.

Safe medication administration requires strict adherence to established protocols. This includes verifying the right client using two acceptable identifiers (such as having them state their full name and date of birth), checking the correct medication against the official medication administration record, and ensuring safety by actively confirming the client's allergy status before giving any drug.

Step-by-Step Solution

Identify the core requirements for safe medication administration.

The nurse must verify the right client, the right medication, and perform client safety checks like confirming allergies.

These foundational principles, known as the 'rights of medication administration', prevent adverse events and errors.

Evaluate the provided actions against established safety protocols and the PN scope of practice.

Checking name/date of birth, checking the MAR, and asking about allergies are safe and correct. Relying on room numbers or independently altering prescribed medication routes are unsafe and out of scope.

To distinguish safe, authorized nursing actions from those that violate safety standards or exceed licensure limits.

Question 766Question →

Following a percutaneous liver biopsy, a client complains of back stiffness and requests a change in body position. To minimize the risk of internal hemorrhage while addressing the client's comfort needs, how should the practical nurse position this individual?

Turn the client onto the right side with a folded towel underneath the puncture area

Help the client into a semi-seated arrangement with the head elevated forty-five degrees

Roll the client onto the left side and place a support pillow between the knees

Place the client facedown to apply uniform abdominal pressure

Show answer & explanation

Answer: Turn the client onto the right side with a folded towel underneath the puncture area

Answer

The nurse should turn the client onto the right side with a folded towel underneath the puncture area to apply direct pressure to the biopsy site.

The correct position applies localized, direct pressure to the right-sided biopsy site using the client's own body weight and a supportive towel. This is the standard basic care intervention to prevent bleeding from the highly vascular liver while safely accommodating the client's need for a position change.

Step-by-Step Solution

Identify the anatomical location of the liver and the purpose of post-biopsy positioning.

The liver is located in the right upper quadrant and is highly vascular, making hemorrhage a primary post-procedure risk.

Understanding the anatomical risks determines the therapeutic positioning requirements.

Determine the optimal position that achieves both comfort and therapeutic compression.

Positioning the client on the right side provides gravity-assisted pressure directly against the biopsy site.

Direct pressure promotes hemostasis and prevents bleeding from the liver capsule.

Question 767Question →

A client on the surgical unit requires a routine change of a two-piece colostomy pouching system. The licensed practical/vocational nurse is preparing to perform the procedure. In what order should the nurse perform the following actions? Arrange the steps in the correct chronological sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for changing an ostomy pouching system is to first remove the old appliance, cleanse the area with warm water, thoroughly dry the skin, measure the stoma, cut the new skin barrier 1/8 inch larger than the stoma, and finally apply the new barrier.

Changing an ostomy pouch requires a methodical approach to maintain skin integrity and ensure a secure seal. The nurse must first safely remove the soiled appliance by supporting the skin to prevent epidermal stripping. Next, gentle cleansing with warm tap water removes effluent without leaving chemical residues. Drying is critical because adhesives fail on moist skin. Once dry, measuring the stoma ensures an accurate fit, as stomas can shrink or swell over time. Cutting the barrier 1/8 inch larger prevents strangulation of the stoma tissue while protecting the skin. Finally, the prepared barrier is applied securely.

Step-by-Step Solution

Remove the existing ostomy appliance.

The stoma and peristomal skin are exposed for assessment.

The old, soiled pouch must be removed carefully to prevent skin trauma and provide access to the stoma.

Cleanse the stoma and skin with warm tap water.

Fecal effluent and adhesive residue are removed.

Cleaning prevents skin breakdown and prepares the surface for the new adhesive. Warm water is used to avoid chemical irritation from soaps.

Thoroughly dry the peristomal area.

The skin is completely free of moisture.

Moisture interferes with the adhesion of the new skin barrier, which can lead to leaks and severe skin breakdown.

Measure the stoma using a measuring guide.

The exact current dimensions of the stoma are determined.

Stoma size can change (especially post-operatively), and an accurate measurement is required to cut the barrier correctly.

Cut the skin barrier 1/8 inch larger than the measurement.

A properly sized opening is created in the wafer.

Leaving a 1/8 inch clearance prevents the wafer from cutting into the stoma, which could cause ischemia, while still protecting the surrounding skin from effluent.

Apply the new skin barrier.

The stoma is secured with a fresh pouching system.

To collect effluent effectively and protect the surrounding skin from enzymatic drainage.

Question 768Question →

A client who underwent a subtotal thyroidectomy earlier today reports experiencing severe upper back tension. The client asks the nurse to lay the bed completely flat to facilitate sleep. Which action is most appropriate for the nurse to take?

Explain the need for a semi-Fowler's position and arrange pillows to securely support the head, neck, and shoulders.

Position the client flat on their back and place a rolled towel beneath the cervical spine to stretch the muscles.

Assist the client onto their side with the mattress completely flat to encourage rest and prevent aspiration.

Flatten the bed temporarily to perform a soothing back massage before returning the mattress to an upright angle.

Show answer & explanation

Answer: Explain the need for a semi-Fowler's position and arrange pillows to securely support the head, neck, and shoulders.

Answer

The correct action is to keep the client in a semi-Fowler's position while arranging pillows to support the head, neck, and shoulders in a neutral alignment.

Following a thyroidectomy, maintaining a semi-Fowler's position is a critical safety intervention to decrease venous pressure, minimize surgical site edema, and protect the airway. Providing firm support with pillows keeps the head and neck in a neutral alignment. This relieves the client's upper back muscle tension while simultaneously preventing hyperextension and dangerous strain on the fresh suture line.

Step-by-Step Solution

Analyze the physiological implications of the surgical procedure.

A subtotal thyroidectomy involves a neck incision, carrying a high risk of localized edema and hemorrhage that can rapidly compress the trachea.

Understanding the specific post-operative risks establishes the foundation for safe positioning.

Evaluate the safety of the client's comfort request.

The client requested a completely flat bed. Lying flat increases venous pressure in the head and neck, which exacerbates surgical site edema.

The nurse must determine if a comfort measure contraindicates medical safety requirements.

Identify the proper anatomical alignment needed.

The neck must be kept in a neutral position to prevent tension on the suture line; hyperextension or extreme flexion must be avoided.

Proper alignment prevents wound dehiscence and further tissue trauma.

Select the nursing intervention that safely addresses both safety and comfort.

Maintaining a semi-Fowler's position (30-45 degrees) prevents airway edema, while strategically placed pillows relieve the upper back tension without compromising neck neutrality.

This balances the ABCs (Airway, Breathing, Circulation) with the core nursing duty of providing basic care and comfort.

Question 769Question →

A practical nurse is providing basic care for a client who is 24 hours post-operative and experiencing temporary dysphagia. The nurse is preparing to assist the client with their first oral meal. Which of the following actions should the nurse take to promote safety? (Select all that apply)

Select all that apply

Elevate the head of the bed to a high-Fowler's position before starting the meal.

Provide a drinking straw to help the client easily consume thin liquids.

Encourage the client to tuck their chin downward toward their chest when swallowing.

Lower the head of the bed to a flat, supine position immediately after the meal to promote rest.

Ensure that functioning suction equipment is readily available at the client's bedside.

Assign an unlicensed assistive personnel to perform the initial feeding to assess the client's tolerance.

Show answer & explanation

Answer: Elevate the head of the bed to a high-Fowler's position before starting the meal.; Encourage the client to tuck their chin downward toward their chest when swallowing.; Ensure that functioning suction equipment is readily available at the client's bedside.

Answer

The nurse should elevate the head of the bed to a high-Fowler's position, encourage the use of a chin-tuck maneuver, and ensure suction equipment is available at the bedside.

For a client with dysphagia, basic care centers on protecting the airway and facilitating safe nutrition. Elevating the head of the bed to a high-Fowler's position uses gravity to help food travel down the esophagus. Instructing the client to tuck their chin while swallowing physically narrows the trachea opening, providing additional protection against aspiration. Finally, having suction equipment immediately available is an essential proactive safety measure in case a choking emergency occurs.

Step-by-Step Solution

Identify the client's condition and associated risks.

The client is post-operative with dysphagia, making airway compromise and aspiration the highest priority concerns during oral intake.

Recognizing the risk of aspiration guides the selection of safe feeding interventions.

Determine appropriate positioning for the meal.

The client must be seated fully upright (high-Fowler's) during the meal and use physical techniques like a chin-tuck to swallow.

Upright positioning and airway-narrowing techniques physically prevent food and fluid from entering the trachea.

Evaluate the safety and appropriateness of additional interventions.

Suction must be present for emergencies. Straws, thin liquids, supine positioning, and delegating the initial assessment must be avoided.

Basic care must prioritize Airway, Breathing, and Circulation (ABCs) and remain strictly within the nurse's scope of practice.

Show answer & explanation

Answer: Administering the inactivated influenza vaccine (IIV) into the deltoid muscle as prescribed.; Reinforcing the provider's explicit instructions to taper the oral prednisone dose rather than abruptly discontinuing the medication.; Withholding the initial dose of amoxicillin and notifying the provider after the caregiver reports the child developed hives from penicillin in the past.

Answer

The correct actions include administering the inactivated influenza vaccine, reinforcing instructions to taper the prednisone, and withholding the amoxicillin if a penicillin allergy is reported.

Safe pharmacological practice requires the nurse to synthesize current client data, recognize contraindications, and strictly adhere to administration standards. Administering an inactivated vaccine is safe during corticosteroid therapy. Reinforcing the critical need to taper steroids prevents acute adrenal crisis and is firmly within the PN scope of practice. Furthermore, withholding a medication and notifying the provider upon discovering a relevant allergy (such as a penicillin allergy for an amoxicillin prescription) is an essential, life-saving intervention.

Step-by-Step Solution

Analyze the client's current medication profile and immune status.

The child is receiving high-dose oral prednisone, which causes systemic immunosuppression.

A client's current immune status dictates which pharmacological therapies, specifically vaccines, are safe to administer.

Evaluate the safety of the prescribed vaccines against the client's immunosuppressed state.

The inactivated influenza vaccine (IIV) is safe, but the live-attenuated MMR vaccine is strictly contraindicated.

Live vaccines can cause severe, unmanageable infections in immunocompromised individuals, whereas inactivated vaccines do not pose this risk.

Assess the PN's intended actions regarding medication administration principles and legal scope of practice.

Proper calibrated dosing tools must be utilized, two unique patient identifiers are legally required regardless of familiarity, and teaching reinforcement regarding corticosteroid tapering is mandatory.

Strict adherence to the core rights of medication administration and the defined LPN/LVN scope of practice prevents life-threatening sentinel events.

Key Concept

Pharmacological safety principles, including vaccine contraindications in immunosuppressed clients and strict adherence to medication administration rights.

The therapeutic range for an International Normalized Ratio (INR) during standard warfarin therapy is generally

2.0

3.0

. An INR of

4.5

is significantly elevated, meaning the blood is clotting too slowly and the client is at a high risk for spontaneous bleeding. The safest and most appropriate action within the practical nurse's scope of practice is to withhold the scheduled medication to prevent further harm, and immediately report the critical laboratory value to the supervising RN or healthcare provider. This ensures the provider can evaluate the client, adjust future dosages, and potentially prescribe an antidote (such as vitamin K) if indicated.

Step-by-Step Solution

Evaluate the client's laboratory result against standard therapeutic values.

The client's INR is

4.5

The standard therapeutic range for a client on warfarin therapy for a deep vein thrombosis is

2.0

3.0

. An INR of

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with hand hygiene and gloving, followed by cleansing the meatus, initiating the urine stream into the toilet, collecting the midstream sample in the cup, and finally securing the container lid.

To collect an uncontaminated clean-catch urine specimen, the nurse must first perform hand hygiene and don gloves. Next, the perineal area is cleansed from front to back to remove surface bacteria. The client is then instructed to void a small amount into the toilet to flush the urethra. The sterile container is placed in the active urine stream to catch the sample. Finally, the lid is secured tightly without touching the inside to maintain specimen sterility.

Step-by-Step Solution

Identify the primary goal of the diagnostic collection procedure.

The goal is to obtain an uncontaminated urine sample for culture and sensitivity testing.

Understanding the goal highlights the importance of asepsis throughout the procedure.

Determine the initial preparatory safety steps.

Hand hygiene and applying clean gloves are the universal first steps to protect both the client and the nurse.

Standard precautions must precede any direct client contact or specimen collection.

During morning medication rounds, a practical nurse (PN) approaches an alert and oriented client to give them their daily oral antibiotic. What is the most appropriate action for the PN to take to verify the client's identity prior to administration?

Ask the client to state their full name and date of birth while comparing this information to the identification band and medication administration record.

Ask the client, 'Are you the patient who is scheduled to receive antibiotics today?' and confirm the room number on the door.

Compare the name listed on the medication administration record with the name written on the dry-erase board above the client's bed.

Scan the medication barcode and administer the dose if the electronic health record photo visually matches the client without speaking to them.

Show answer & explanation

Answer: Ask the client to state their full name and date of birth while comparing this information to the identification band and medication administration record.

Answer

The most appropriate action is to ask the client to explicitly state their full name and date of birth while verifying this against the identification band and official records.

The correct action directly adheres to standard medication administration safety principles. Using two distinct, acceptable patient identifiers (such as full name and date of birth) and having an alert client actively state their information while the nurse cross-references it with the ID band and MAR is the gold standard for preventing medication errors.

Step-by-Step Solution

Identify the standard protocol for safe medication administration regarding patient identification.

The standard protocol requires the use of at least two acceptable, distinct patient identifiers before administering any medication.

This fundamental safety check prevents medication errors and ensures the right drug goes to the right patient.

Evaluate each option based on the criteria for two acceptable identifiers and active client participation.

Asking the client to state their name and date of birth fulfills both criteria safely. The other methods rely on invalid identifiers like room numbers or passive verification.

Active verification (having the client speak their details) combined with official document checks (ID band and MAR) is the most reliable method for an alert client.

Question 775Question →

During morning rounds, a practical nurse (PN) evaluates a client with cirrhosis and hepatic encephalopathy who is prescribed oral lactulose and oral spironolactone. The electronic health record reveals a morning serum potassium level of 2.8 mEq/L. The client currently exhibits bilateral asterixis and reports having three soft bowel movements over the past 12 hours. Which action should the PN take first?

Document the potassium level in the medical record and administer the lactulose to treat the asterixis

Administer the spironolactone, but independently discontinue the lactulose prescription due to the hypokalemia

Withhold the scheduled lactulose dose and immediately report the serum potassium results to the supervising registered nurse (RN)

Administer the scheduled medications, as the three bowel movements indicate the lactulose is achieving its expected therapeutic effect

Show answer & explanation

Answer: Withhold the scheduled lactulose dose and immediately report the serum potassium results to the supervising registered nurse (RN)

Answer

The correct action is to withhold the scheduled lactulose dose and immediately report the critical serum potassium results to the supervising registered nurse.

The client's potassium level of 2.8 mEq/L is critically low. Because lactulose induces osmotic diarrhea to eliminate ammonia, it inherently causes additional potassium loss through the gastrointestinal tract. Administering lactulose in the presence of severe hypokalemia places the client at imminent risk for lethal cardiac dysrhythmias. Furthermore, hypokalemia directly increases renal ammonia production, which ultimately worsens hepatic encephalopathy. The safest and most appropriate action within the practical nurse's scope of practice is to withhold the medication and immediately escalate the critical laboratory finding to the registered nurse for urgent intervention.

Step-by-Step Solution

Analyze the clinical laboratory data and physical assessment findings

The serum potassium is 2.8 mEq/L (critical hypokalemia). Asterixis is present (indicating active encephalopathy). Three soft stools indicate the lactulose is effectively increasing bowel motility.

Establishing the client's baseline physiological status is required before administering high-risk medications.

Evaluate the pharmacological mechanism and adverse effects of lactulose

Lactulose acts as an osmotic laxative to trap and excrete ammonia in the stool; however, this mechanism inherently causes significant gastrointestinal loss of water and electrolytes, specifically potassium.

Understanding the mechanism of action highlights the direct conflict between the medication's effect and the client's current potassium deficit.

Synthesize the physiological risks

Administering lactulose will worsen the severe hypokalemia, placing the client at imminent risk for lethal cardiac dysrhythmias. Additionally, severe hypokalemia actually increases renal ammonia production, paradoxically worsening the encephalopathy.

Clinical judgment requires balancing the therapeutic need (treating encephalopathy) against immediate life-threatening physiological risks (cardiac dysrhythmia from hypokalemia).

Determine the appropriate intervention within the PN scope of practice

The PN must withhold the unsafe medication and urgently escalate the critical potassium value to the RN for medical intervention.

A PN cannot independently alter medical prescriptions, but has a duty to withhold harmful medications and report critical findings.

Key Concept

Recognizing severe hypokalemia as an absolute contraindication for administering osmotic laxatives, and adhering to the PN scope of practice by withholding the drug and escalating critical labs.

0.05\text{ mg}

) must first be converted to the same unit as the available medication (

25\text{ mcg}

tablets). Multiplying

0.05\text{ mg}

1000

yields

50\text{ mcg}

. Using the standard formula (Desired divided by Have),

50\text{ mcg}

divided by

25\text{ mcg}

equals

2

tablets.

Step-by-Step Solution

Convert the prescribed dose to match the unit of the available medication.

0.05\text{ mg} = 50\text{ mcg}

Safe medication administration requires calculations to be performed using the same unit of measurement.

Calculate the number of tablets using the standard dosage formula.

\frac{50\text{ mcg}}{25\text{ mcg}} \times 1\text{ tablet} = 2\text{ tablets}

This determines the exact physical quantity to administer to the client to achieve the prescribed dose.

Question 777Question →

A client with dysphagia receives continuous enteral feedings via a nasogastric (NG) tube. The healthcare provider has ordered two distinct liquid medications to be given via the tube. After pausing the feeding pump, in what sequence should the practical nurse (PN) execute the following actions to safely deliver these medications?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with positioning the client, verifying tube placement, performing an initial water flush, administering the first medication via gravity, performing an intermediate flush, and finally administering the second medication followed by a terminal flush.

Safe administration of medications via an enteral tube requires strict adherence to sequential safety checks. Elevating the head of the bed minimizes aspiration risk. Verifying placement ensures the tube has not migrated to the lungs. Flushing before, between, and after medications verifies patency, prevents drug-nutrient/drug-drug incompatibilities, and ensures the full dose reaches the stomach. Gravity administration prevents excessive pressure that could rupture the tube.

Step-by-Step Solution

Elevate the head of the bed.

The client is safely positioned at 30 degrees or higher.

Reduces the risk of pulmonary aspiration during the medication administration process.

Verify tube placement and check residual.

Gastric placement is confirmed, ensuring safety.

Guarantees medications will enter the gastrointestinal tract and not the respiratory system.

Perform the initial water flush.

The tube is cleared of formula and patency is established.

Prevents drug-nutrient interactions and ensures the tube is unblocked.

Administer the first medication via gravity.

The first dose enters the stomach safely.

Gravity flow prevents excess pressure, while administering one medication at a time avoids drug interactions.

Flush with 15 to 30 mL of water.

The tube is cleared of the first medication.

Prevents drug-drug interactions or precipitation inside the tube when multiple medications are ordered.

Administer the second medication and the final flush.

All medications are delivered and the tube is thoroughly cleared.

Ensures complete dosing and maintains long-term tube patency.

A practical nurse (PN) is reviewing the electronic health record for a client with heart failure who is prescribed digoxin $0.25\text{ mg}$ PO and furosemide $40\text{ mg}$ PO daily. Morning assessment data reveals an apical pulse of $54\text{ beats/min}$ and a serum potassium level of $2.8\text{ mEq/L}$ . Which action should the PN take?

Withhold both medications and immediately escalate the assessment findings to the registered nurse (RN).

Administer the furosemide to promote diuresis, but withhold the digoxin because the apical pulse is below

60\text{ beats/min}

Administer the digoxin after verifying the client using their name and room number, but withhold the furosemide.

Obtain the intravenous (IV) formulations of both medications and administer them via IV push to ensure rapid absorption.

Show answer & explanation

Answer: Withhold both medications and immediately escalate the assessment findings to the registered nurse (RN).

Answer

The PN must withhold both the digoxin and the furosemide and immediately escalate the assessment findings to the registered nurse (RN).

The correct action is to withhold both medications. Digoxin requires an apical pulse of at least

60\text{ beats/min}

for safe administration; the client's pulse is

54\text{ beats/min}

. Furosemide is a loop diuretic that wastes potassium; administering it to a client with a critically low potassium level of

2.8\text{ mEq/L}

would dangerously worsen the hypokalemia. Furthermore, hypokalemia increases the risk of digoxin toxicity. The PN must withhold the doses and report these critical findings to the RN immediately.

Step-by-Step Solution

Evaluate the client's vital signs against medication administration parameters.

The apical pulse is

54\text{ beats/min}

, which is below the standard

60\text{ beats/min}

threshold for administering digoxin.

Digoxin has a negative chronotropic effect (slows heart rate). Giving it during bradycardia can lead to severe cardiac compromise.

Analyze the laboratory results in the context of the prescribed medications.

The serum potassium is

2.8\text{ mEq/L}

(normal is

3.5

5.0\text{ mEq/L}

). Furosemide is a loop diuretic that causes potassium loss.

Administering furosemide will exacerbate the severe hypokalemia, which can trigger fatal dysrhythmias.

Synthesize the interaction between the laboratory findings and digoxin.

Hypokalemia increases myocardial sensitivity to digoxin.

Even at normal dosage levels, low potassium increases the risk of digoxin toxicity.

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

The PN must withhold both contraindicated medications and escalate the critical findings to the RN or provider.

Operating safely within the PN scope requires recognizing abnormal data, withholding harmful interventions, and communicating with the supervising RN.

Key Concept

Pharmacological safety involves synthesizing vital signs, laboratory data, and drug interactions to recognize critical administration contraindications.

Question 779Question →

A practical nurse (PN) is planning care for a client who is 48 hours postoperative following a right above-the-knee amputation. The client is receiving continuous enteral nutrition via a nasogastric tube and has a prescription to be placed in the prone position for 30 minutes twice daily. Which action should the PN take to safely implement this positioning requirement?

Stop the continuous enteral feeding for 30 to 60 minutes before assisting the client into the prone position.

Disconnect the feeding tube from the pump and immediately assist the client into the prone position.

Maintain the continuous feeding during the procedure but ensure the client's head is turned to the side to protect the airway.

Place a supportive pillow directly under the right residual limb to elevate it while the client lies prone.

Show answer & explanation

Answer: Stop the continuous enteral feeding for 30 to 60 minutes before assisting the client into the prone position.

Answer

Stop the continuous enteral feeding for 30 to 60 minutes before assisting the client into the prone position.

The correct action demonstrates the ability to safely coordinate two conflicting care requirements. Prone positioning is essential to stretch the flexor muscles and prevent hip contractures following an above-the-knee amputation. However, placing a client flat while their stomach contains enteral formula creates a high risk for aspiration. By stopping the feeding 30 to 60 minutes beforehand, the nurse allows time for gastric emptying, protecting the airway while fulfilling the postoperative basic care prescription.

Step-by-Step Solution

Identify the primary clinical goals for this client.

The client needs prone positioning to prevent hip flexion contractures (post-amputation) and requires protection from aspiration due to continuous enteral feeding.

Recognizing competing physiological needs is the first step in prioritizing safe care.

Analyze the positioning requirements for both interventions.

Prone positioning requires the client to lie flat on their abdomen. Enteral feeding requires the head of the bed to be elevated at least 30 to 45 degrees.

Lying flat while receiving enteral feeds or immediately after feeding poses a severe aspiration risk.

Determine the appropriate sequencing of care.

The feeding must be paused in advance of the position change to allow for gastric emptying.

Stopping the feed 30 to 60 minutes prior ensures the stomach is relatively empty when the client is placed flat, adhering to ABC (Airway, Breathing, Circulation) prioritization while meeting basic care needs.

A practical nurse is caring for a client who returned to the medical-surgical unit one hour ago following a percutaneous liver biopsy. Which of the following interventions should the nurse include in the client's plan of care? Select all that apply.

Select all that apply

Maintain the client in a right side-lying position.

Place a small pillow or folded towel under the puncture site.

Offer the client a bedpan or urinal for elimination needs.

Assist the client to sit on the edge of the bed to consume a meal.

Administer an intravenous (IV) push opioid analgesic for reports of pain.

Encourage the client to perform deep coughing exercises every hour.

Show answer & explanation

Answer: Maintain the client in a right side-lying position.; Place a small pillow or folded towel under the puncture site.; Offer the client a bedpan or urinal for elimination needs.

Answer

The correct interventions are to maintain the client in a right side-lying position, place a small pillow under the puncture site, and offer a bedpan for elimination.

The correct actions involve placing the client in a right side-lying position with a towel or small pillow under the puncture site to apply direct, localized pressure to the highly vascular liver. This physical pressure is critical to prevent hemorrhage. Furthermore, because the client must remain on strict bed rest for several hours to maintain this pressure, the nurse must assist with basic care by providing a bedpan or urinal for urinary elimination.

Step-by-Step Solution

Identify the primary risk associated with a percutaneous liver biopsy.

The liver is a highly vascular organ, making post-procedure hemorrhage the most significant complication.

Understanding the primary circulatory risk directs the choice of appropriate basic care and positioning interventions.

Determine the correct post-procedure positioning to address the risk.

The client must be placed in a right side-lying position with a pillow or towel under the right costal margin.

This specific positioning utilizes the client's own body weight to apply direct, localized pressure to the liver capsule, preventing bleeding.

Evaluate the remaining basic care needs based on activity restrictions.

Because the client is on strict bed rest to avoid dislodging the clot, the nurse must provide a bedpan or urinal for elimination rather than allowing ambulation.

Maintaining strict bed rest minimizes intra-abdominal pressure and protects the fragile clot at the puncture site.
