A client with a history of stable angina is prescribed a daily nitroglycerin transdermal patch. After gathering the necessary supplies, entering the client's room, and verifying the client using two identifiers, the practical nurse proceeds with the medication administration. Arrange the following actions in the correct sequential order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Don clean gloves, remove the old patch, clean the old site, label the new patch, and apply the new patch.

Safe transdermal patch administration requires a strict sequence to ensure client safety and protect the nurse. The nurse must first don gloves to prevent absorbing the medication. Next, the old patch must be removed and safely discarded, and the old site must be thoroughly cleaned to prevent an overdose from residual medication. The new patch is then labeled with the date, time, and initials prior to application to avoid causing discomfort by writing directly on the client's skin. Finally, the patch is firmly applied to a new, hairless site to ensure consistent absorption and prevent tissue irritation.

Step-by-Step Solution

Put on a pair of clean gloves.

The nurse's hands are protected from the medication.

Nitroglycerin can be absorbed through the nurse's skin, causing adverse effects such as a severe headache or hypotension.

Remove the previously applied patch and fold the adhesive sides together.

The continuous delivery of the previous dose is halted.

Failing to remove the old patch before applying a new one can lead to a dangerous medication overdose.

Wash the old application site with soap and water, then dry the skin completely.

The skin is clear of residual medication.

Residual nitroglycerin left on the skin continues to be absorbed; cleaning the site ensures accurate dosing of the new patch.

Write the current date, time, and nurse's initials on the outer backing of the new patch.

The new patch is properly identified for future shifts.

Writing on the patch before applying it prevents the nurse from pressing a pen into the client's skin.

Press the newly labeled patch firmly onto a different, hairless area of the upper chest or arm.

The new dose is securely administered.

Site rotation prevents skin breakdown and irritation, while applying to a hairless area ensures optimal skin contact and absorption.

The client's current vital signs reveal a heart rate of 114 beats per minute and a blood pressure of 96/64 mm Hg. The client, who was previously fully oriented, is now restless, repeatedly asking where they are, and picking at the bed linens. Which action should the practical nurse take first?

Measure the client's oxygen saturation level and immediately notify the registered nurse.

Reorient the client to the hospital room and ensure the bed alarm is activated.

Administer the prescribed as-needed analgesic to help calm the client.

Document the current vital signs and reassess the client at the next scheduled interval.

Show answer & explanation

Answer: Measure the client's oxygen saturation level and immediately notify the registered nurse.

Answer

Measure the client's oxygen saturation level and immediately notify the registered nurse.

The correct action prioritizes the collection of critical respiratory data and immediate escalation. A sudden change in mental status accompanied by tachycardia and borderline hypotension strongly suggests hypoxia or early shock. The practical nurse must prioritize Airway, Breathing, and Circulation (ABC) assessments and promptly notify the registered nurse for collaborative management.

Step-by-Step Solution

Analyze the clinical cues presented by the client.

The client has tachycardia, borderline hypotension, and a sudden change in mental status including restlessness and confusion.

Identifying abnormal findings is the first step in clinical reasoning.

Correlate the clinical cues with potential complications.

These findings are classic early signs of hypoxia or hypovolemic shock, which are life-threatening conditions.

Understanding the physiological meaning of the symptoms determines the urgency of the situation.

Determine the priority action within the practical nurse scope of practice.

The priority is to gather targeted respiratory data and escalate the findings to the registered nurse for immediate medical intervention.

Airway, Breathing, and Circulation (ABC) issues take precedence over routine care or symptom management.

Question 403Question →

A practical nurse (PN) is caring for a 16-year-old client who is 4 hours postoperative following a tonsillectomy. The client is awake but quietly and repeatedly swallowing. The client's heart rate has increased from 78 bpm to 110 bpm over the last hour, while blood pressure has decreased slightly from 118/74 mm Hg to 108/66 mm Hg. Which of the following is the most appropriate action for the PN to take?

Notify the registered nurse immediately regarding the assessment findings.

Document the frequent swallowing and vital signs as expected postoperative findings.

Offer the client sips of clear, cool liquids to soothe the throat.

Increase the intravenous fluid rate to compensate for the slight drop in blood pressure.

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the assessment findings.

Answer

Notify the registered nurse immediately regarding the assessment findings.

The correct action is to notify the registered nurse immediately. In a post-tonsillectomy client, frequent swallowing is a hallmark sign of active bleeding trickling down the throat. When combined with an increasing heart rate and a slightly decreasing blood pressure, these findings strongly indicate early hypovolemic shock. Prompt escalation is necessary to stabilize the client and prevent further deterioration.

Step-by-Step Solution

Analyze the client's postoperative presentation and behavioral cues.

The client is 4 hours post-tonsillectomy and is repeatedly swallowing.

Frequent swallowing is a classic indicator that blood is pooling in the posterior pharynx, suggesting active surgical site bleeding.

Evaluate the trend in the client's vital signs over the past hour.

The heart rate has increased significantly (tachycardia) and the blood pressure has started to drop.

These vital sign changes represent the body's compensatory mechanisms attempting to maintain cardiac output during early hypovolemic shock caused by hemorrhage.

Determine the priority nursing action based on the practical nurse's scope of practice.

The practical nurse must immediately escalate the situation to the registered nurse.

Active hemorrhage is a life-threatening complication requiring immediate comprehensive assessment, potential medical intervention, and possible return to the operating room.

Key Concept

Show answer & explanation

Answer: Report the changing clinical parameters to the supervising registered nurse immediately.; Evaluate the client's lung sounds, respiratory rate, and pulse oximetry readings.; Anticipate assisting the registered nurse with a rapid intravenous fluid bolus or stat laboratory draws.

Answer

The correct actions are to report the changing clinical parameters to the supervising registered nurse immediately, evaluate the client's respiratory status, and anticipate assisting with rapid fluid resuscitation or laboratory draws.

The client is exhibiting early signs of decreased tissue perfusion and potential systemic inflammatory response syndrome (SIRS) or sepsis, evidenced by oliguria, tachycardia, a downward trend in blood pressure, and altered mental status. Immediate escalation to the RN, evaluating respiratory function (ABCs), and preparing for rapid therapeutic interventions (like fluids and cultures) are critical, life-saving actions within the practical nurse's scope of practice.

Step-by-Step Solution

Analyze the clinical cues presented in the scenario.

The client has oliguria (55 mL over 4 hours is roughly 14 mL/hr, which is well below the minimum 30 mL/hr), a rising heart rate, falling blood pressure, and new-onset agitation.

Recognizing abnormal assessment data is the first step in clinical judgment.

Synthesize the cues to identify the underlying physiological problem.

The combination of these subtle but progressive signs indicates early systemic hypoperfusion, likely related to sepsis from the severe cellulitis.

Understanding the pathophysiology of infection leading to shock helps determine the urgency of the situation.

Determine the appropriate practical nurse interventions.

The priority is to maintain ABCs (assessing respiratory status), immediately escalate the findings to the RN for rapid medical management, and prepare to assist with emergency interventions.

The PN scope of practice requires prompt reporting of unstable physiological changes and assisting the healthcare team in stabilizing the client.

Question 405Question →

A practical nurse is caring for an adult client experiencing an acute asthma exacerbation. The client appears restless, and auscultation of the lungs reveals bilateral expiratory wheezing. The client's current vital signs are blood pressure 134/86 mmHg, heart rate 114 beats per minute, respiratory rate 26 breaths per minute, and oxygen saturation 92% on room air. The healthcare provider has prescribed an immediate albuterol nebulizer treatment and an oral dose of prednisone. Which action should the nurse take first?

Withhold the albuterol nebulizer and notify the provider, as the client is already experiencing tachycardia.

Delegate the administration of the oral prednisone to an unlicensed assistive personnel (UAP) while preparing the nebulizer.

Administer the albuterol nebulizer treatment before providing the oral prednisone.

Administer the oral prednisone immediately without checking the client's identification band to save time.

Show answer & explanation

Answer: Administer the albuterol nebulizer treatment before providing the oral prednisone.

Answer

Administer the albuterol nebulizer treatment before providing the oral prednisone.

The correct action is to administer the albuterol nebulizer treatment first. Albuterol is a short-acting beta-2 agonist (SABA) that causes rapid bronchodilation, addressing the client's immediate airway and breathing needs. Prednisone is a corticosteroid that reduces airway inflammation, but its onset of action takes several hours. In an acute respiratory scenario, the nurse must prioritize the fastest-acting rescue medication to stabilize the client's airway before administering slower-acting oral medications.

Step-by-Step Solution

Assess the client's clinical presentation and vital signs.

The client is in acute respiratory distress with wheezing, hypoxia (SpO2 92%), and tachycardia (HR 114 bpm).

Baseline assessment data dictates the urgency and prioritization of pharmacological interventions.

Analyze the prescribed medications based on their onset of action and mechanisms.

Albuterol is a rapid-acting bronchodilator. Prednisone is a slower-acting systemic corticosteroid.

Understanding pharmacokinetics ensures the fastest-acting rescue medication is given first.

Prioritize administration based on the airway, breathing, and circulation (ABC) framework.

The albuterol nebulizer is administered first to immediately open the airways, followed by the oral prednisone to manage underlying inflammation.

Airway patency and breathing are the highest physiological priorities in an asthma exacerbation.

Key Concept

During an acute respiratory exacerbation, rapid-acting bronchodilators (like albuterol) must be prioritized over slower-acting anti-inflammatory medications (like oral corticosteroids) to immediately secure the airway and improve breathing.

Show answer & explanation

Answer: Heart rate of $118$ beats/min with a blood pressure of $88/54$ mm Hg; Saturation of one perineal pad within a $15$ -minute timeframe; Client report of new, severe perineal pressure that is unrelieved by analgesia

Answer

The findings requiring immediate escalation are the elevated heart rate with hypotension, the rapidly saturated perineal pad, and the severe, unrelieved perineal pressure.

A heart rate of

118

beats/min with a blood pressure of

88/54

mm Hg are classic signs of impending hypovolemic shock. Saturation of a perineal pad in

15

minutes or less indicates active postpartum hemorrhage. Severe, unrelieved perineal pressure is a hallmark sign of a developing vaginal or vulvar hematoma. All of these findings indicate potentially life-threatening complications that require immediate escalation to the registered nurse for rapid intervention.

Step-by-Step Solution

Analyze the clinical scenario for the primary risk factors.

The client is in the immediate postpartum period following a vaginal delivery, making hemorrhage and hematoma formation the primary life-threatening risks.

Identifying the highest risk potential guides the prioritization of clinical data.

Evaluate each finding to differentiate between normal physiological adaptations and potential complications.

Tachycardia with hypotension, rapid pad saturation, and severe pressure are abnormal findings indicating shock, active bleeding, or hematoma.

Recognizing deviations from expected postpartum recovery is essential for safe practice.

Identify the expected, benign findings that do not require escalation.

Mild temperature elevation, leukocytosis, and the expulsion of pooled lochia upon standing are normal physiological responses to childbirth.

Accurate clinical judgment prevents unnecessary escalation and focuses care on true emergencies.

Question 407Question →

A practical nurse in a long-term care facility is reviewing a new medication order for a resident diagnosed with a lower respiratory tract infection. The provider's prescription reads: 'Azithromycin $500\text{ mg}$ PO on day 1, followed by $250\text{ mg}$ PO daily on days 2 through 5.' The pharmacy dispenses an azithromycin oral suspension with a concentration of $200\text{ mg}/5\text{ mL}$ . How many total milliliters (mL) of this medication will the nurse administer over the entire 5-day treatment course? (Record answer to the nearest tenth. Do not include units in answer.)

Show answer & explanation

Answer: 37.5

Answer

37.5

The prescription requires a total of

1,500\text{ mg}

of azithromycin over 5 days (

500\text{ mg}

on day 1, plus

1,000\text{ mg}

over days 2 through 5). Using the supplied concentration of

200\text{ mg}/5\text{ mL}

, the required volume is calculated by dividing

1,500

200

, which equals

7.5

. Multiplying

7.5

5

yields exactly

37.5\text{ mL}

Step-by-Step Solution

Calculate the total milligrams required for the full 5-day prescription.

Day 1 =

500\text{ mg}

. Days 2-5 (4 days) =

1,000\text{ mg}

. Total =

1,500\text{ mg}

To determine the complete volume needed, the total medication dosage over all days must first be established.

Set up the dimensional analysis or standard dosage formula to convert total milligrams to milliliters.

(\frac{1,500\text{ mg}}{200\text{ mg}}) \times 5\text{ mL}

This aligns the prescribed dose with the available concentration (

200\text{ mg}

per

5\text{ mL}

) supplied by the pharmacy.

Solve the equation and round to the nearest tenth as instructed.

7.5 \times 5 = 37.5\text{ mL}

Question 408Question →

A 79-year-old client on a medical-surgical unit is undergoing treatment for a complicated urinary tract infection with intravenous antibiotics. During the night, the client, whose baseline mental status is alert and oriented, becomes highly agitated, attempts to climb out of bed, and pulls at the intravenous line. The practical nurse obtains the following vital signs: temperature 97.2°F (36.2°C), heart rate 118 beats/minute, blood pressure 94/52 mm Hg, and respiratory rate 24 breaths/minute. Which action should the practical nurse take first?

Remain with the client and immediately report the vital signs and behavior changes to the registered nurse.

Apply a protective wrap to the intravenous site to ensure the antibiotic infusion is not interrupted.

Document the behavior in the medical record as expected nighttime disorientation common in older adults.

Continue routine monitoring and plan to check vital signs again in four hours since the client is afebrile.

Show answer & explanation

Answer: Remain with the client and immediately report the vital signs and behavior changes to the registered nurse.

Answer

The priority action is to remain with the client and immediately report the vital signs and behavior changes to the registered nurse.

The correct answer addresses the immediate need for escalation when a client shows signs of acute physiological deterioration. The combination of sudden agitation, tachycardia, tachypnea, and hypotension in a client with a severe infection points directly to early septic shock. The practical nurse correctly identifies the emergency and immediately reports to the registered nurse while keeping the client safe.

Step-by-Step Solution

Analyze the client's new onset of symptoms.

The client has suddenly developed agitation and confusion, deviating from their alert baseline.

Sudden changes in mental status often indicate an acute physiological problem, such as poor cerebral perfusion, not a psychological one.

Evaluate the current vital signs in the context of the client's diagnosis.

Heart rate (118 bpm) is elevated, respiratory rate (24 breaths/min) is elevated, and blood pressure (94/52 mm Hg) is low.

These vital signs suggest circulatory compromise and inadequate tissue perfusion, which are early signs of septic shock associated with the urinary tract infection.

Determine the priority nursing action within the practical nurse scope of practice.

The practical nurse must immediately notify the registered nurse to escalate care while ensuring client safety.

Acute physiological deterioration requires immediate assessment and medical intervention beyond the practical nurse's independent scope.

Key Concept

Recognizing early signs of shock and prioritizing acute physiological changes over secondary equipment issues or assumptions about aging.

Question 409Question →

An adult client with a history of type 2 diabetes mellitus and hypertension is assigned to a practical nurse. During the morning assessment, the client is awake and reports feeling slightly shaky. The vital signs are a blood pressure of 142/88 mm Hg, an apical heart rate of 54 beats/minute, and a capillary blood glucose level of 64 mg/dL (3.5 mmol/L). The medication administration record includes scheduled morning doses of oral glipizide, subcutaneous regular insulin, and oral atenolol. Which of the following actions should the practical nurse take? Select all that apply.

Select all that apply

Withhold the scheduled doses of oral glipizide and subcutaneous regular insulin.

Provide the client with 15 grams of a fast-acting oral carbohydrate.

Withhold the scheduled dose of oral atenolol and report the apical heart rate.

Administer the oral atenolol to manage the client's current blood pressure.

Give the subcutaneous regular insulin and hold the oral glipizide until after a meal.

Delegate the administration of fruit juice and the follow-up blood glucose check to an unlicensed assistive personnel (UAP).

Show answer & explanation

Answer: Withhold the scheduled doses of oral glipizide and subcutaneous regular insulin.; Provide the client with 15 grams of a fast-acting oral carbohydrate.; Withhold the scheduled dose of oral atenolol and report the apical heart rate.

Answer

The practical nurse should withhold the glipizide and regular insulin, provide a fast-acting carbohydrate to treat the hypoglycemia, and withhold the atenolol due to the client's bradycardia.

The client is experiencing both hypoglycemia (blood glucose 64 mg/dL with shakiness) and bradycardia (heart rate 54 beats/minute). Safe nursing practice requires holding all medications that would exacerbate these conditions. Glipizide and regular insulin must be withheld to prevent further drops in blood glucose, and a fast-acting carbohydrate must be given immediately. Atenolol must be withheld because it is a beta-blocker that will further lower the client's heart rate. The nurse must report these abnormal findings to the healthcare provider or registered nurse.

Step-by-Step Solution

Evaluate the capillary blood glucose level against the client's symptoms and scheduled medications.

The blood glucose is 64 mg/dL (hypoglycemia) with symptoms of shakiness.

Recognizing hypoglycemia dictates that medications lowering blood sugar (glipizide, regular insulin) must be withheld and immediate treatment initiated.

Select the appropriate intervention for an awake, hypoglycemic client.

Provide 15 grams of a fast-acting oral carbohydrate.

Oral carbohydrates are the first-line treatment for conscious clients experiencing hypoglycemia to rapidly restore safe blood glucose levels.

Evaluate the vital signs against the scheduled cardiac medication.

The apical heart rate is 54 beats/minute (bradycardia), which is a contraindication for atenolol.

Beta-blockers depress myocardial contractility and heart rate; administering atenolol to a bradycardic client is unsafe.

Key Concept

Safe medication administration requires the nurse to verify that current clinical data, such as vital signs and laboratory values, support the safe administration of scheduled medications.

Question 410Question →

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for obtaining a wound culture is to first remove the soiled dressing, perform hand hygiene and don new gloves, cleanse the wound with normal saline, swab the granulating tissue, and finally place the swab in the collection tube.

To obtain an accurate wound culture without cross-contamination, the PN must first remove the soiled dressing and change gloves. Next, the wound is cleansed with normal saline to remove surface exudate and skin flora. The PN then swabs viable granulating tissue, where the active infection resides, before securing the swab in the sterile tube.

Step-by-Step Solution

Remove the soiled dressing.

The wound bed is exposed.

Necessary to access the site for culture.

Perform hand hygiene and put on new gloves.

Hands are clean and protected.

Prevents introducing bacteria from the old dressing into the wound.

Cleanse the wound with sterile normal saline.

Surface exudate and flora are removed.

Ensures the culture isolates pathogens causing the infection, not surface contaminants.

Swab clean, granulating tissue.

A sample of the infecting organism is obtained.

Pathogens are most concentrated in viable, granulating tissue rather than in slough or purulent drainage.

Place the swab in the collection tube.

The specimen is secured for transport.

Preserves the sample and prevents environmental contamination.

Key Concept

Proper technique for obtaining a wound culture involves cleansing the wound first to avoid culturing surface flora and swabbing only viable tissue.

The client's vital signs are: blood pressure 88/52 mm Hg, heart rate 116 beats/min, and respiratory rate 24 breaths/min. A recent laboratory report shows a hemoglobin level of 8.1 g/dL (81 g/L). Which action should the practical nurse take first?

Continue monitoring the vital signs routinely because mild hypotension is expected following surgery.

File the laboratory report in the electronic health record and wait for the provider to review it during rounds.

Promptly notify the registered nurse about the assessment findings and remain with the client.

Administer a prescribed intravenous push sedative to address the client's increasing restlessness.

Show answer & explanation

Answer: Promptly notify the registered nurse about the assessment findings and remain with the client.

Answer

Promptly notify the registered nurse about the assessment findings and remain with the client.

The correct action demonstrates an understanding of the practical nurse's role in risk reduction. The client's presentation of tachycardia, hypotension, restlessness, pallor, and low hemoglobin strongly suggests postoperative hemorrhage and hypovolemic shock. Because this is an unstable, critical situation requiring advanced assessment, fluid resuscitation, and potential blood transfusions, the practical nurse must immediately notify the registered nurse to escalate care while ensuring client safety by staying at the bedside.

Step-by-Step Solution

Analyze the client's vital signs and clinical presentation.

The client is experiencing hypotension (88/52 mm Hg), tachycardia (116 beats/min), tachypnea (24 breaths/min), pallor, and restlessness.

Identifying abnormal assessment findings is the fundamental first step in recognizing clinical deterioration.

Correlate the physical assessment findings with the recent laboratory data.

The low hemoglobin level (8.1 g/dL) combined with the abnormal vital signs indicates active bleeding and impending hypovolemic shock.

Connecting laboratory values with physical signs provides a comprehensive clinical picture of the postoperative complication.

Determine the appropriate nursing intervention within the practical nurse's scope of practice.

The practical nurse must immediately escalate the situation to the registered nurse for advanced assessment and collaborative management.

Managing acute hypovolemic shock requires RN-level clinical judgment and interventions, such as fluid resuscitation and blood product administration.

Question 412Question →

During a pediatric clinic visit, a practical nurse prepares to administer a scheduled measles, mumps, and rubella (MMR) vaccine to a 15-month-old child. The client's health record indicates a current prescription for high-dose systemic corticosteroids to manage an autoimmune disorder. What is the most appropriate action for the practical nurse to take?

Withhold the MMR vaccine and notify the healthcare provider about the client's corticosteroid therapy.

Administer the vaccine as scheduled to ensure the child remains compliant with standard immunization timelines.

Administer the vaccine without completing the electronic barcode scan as long as the parent verbally confirms the child's identity.

Accept a delegation to administer a prophylactic intravenous (IV) push antihistamine prior to giving the immunization.

Show answer & explanation

Answer: Withhold the MMR vaccine and notify the healthcare provider about the client's corticosteroid therapy.

Answer

The practical nurse should withhold the MMR vaccine and notify the healthcare provider, as live attenuated vaccines are contraindicated for clients receiving immunosuppressive therapies such as high-dose corticosteroids.

The measles, mumps, and rubella (MMR) vaccine is a live attenuated vaccine. Clients receiving high-dose systemic corticosteroids are immunocompromised and lack the necessary cellular immune response to safely process live viruses. Administering a live vaccine to this client could result in a severe or life-threatening infection. Therefore, the safest and most appropriate action is to withhold the dose and alert the provider.

Step-by-Step Solution

Review the client's current medication list and medical history prior to administering any vaccine.

The nurse identifies that the client is actively taking high-dose systemic corticosteroids.

Identifying current medications is essential to determine potential drug interactions or contraindications before proceeding with administration.

Analyze the pharmacological properties of the prescribed vaccine in relation to the client's immune status.

The nurse recognizes that the MMR vaccine contains live attenuated viruses, which are contraindicated for immunocompromised individuals.

High-dose corticosteroids suppress the immune system, significantly increasing the risk of a severe, disseminated infection from a live vaccine.

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

The nurse withholds the immunization and escalates the finding to the prescribing healthcare provider or registered nurse.

Practical nurses must advocate for client safety by holding unsafe medications and communicating critical contraindications to the healthcare team.

Question 413Question →

While observing an 82-year-old client admitted 12 hours ago with severe diarrhea and vomiting, the practical nurse (PN) notes several clinical findings. Which of the following data points strongly suggest the client is developing hypovolemic shock and warrant immediate notification of the registered nurse (RN)? Select all that apply.

Select all that apply

New-onset restlessness and repeated attempts to remove the intravenous catheter

A resting heart rate that has steadily climbed from 86 to 124 beats per minute

A total urine output of 45 mL accumulated over the past three hours

Verbalization of dull, intermittent abdominal cramping

An oral temperature reading of 37.6°C (99.7°F)

Inability to recall the name of the admitting healthcare provider while fully oriented to person and place

Show answer & explanation

Answer: New-onset restlessness and repeated attempts to remove the intravenous catheter; A resting heart rate that has steadily climbed from 86 to 124 beats per minute; A total urine output of 45 mL accumulated over the past three hours

Answer

The findings that indicate acute physiological deterioration and early hypovolemic shock are the new-onset restlessness, the climbing heart rate, and the significantly low urine output.

In a client experiencing severe fluid loss, hypovolemia can rapidly progress to shock. The body compensates for the decreased blood volume by increasing the heart rate to maintain cardiac output. As blood flow to vital organs diminishes, the client exhibits signs of cerebral hypoxia (restlessness and agitation) and decreased renal perfusion (oliguria, defined as less than 30 mL/hr). Recognizing this cluster of systemic signs is essential for prompt intervention.

Step-by-Step Solution

Identify the client's primary risk factor based on the admission diagnosis.

The client has severe gastroenteritis, which places them at high risk for fluid volume deficit and hypovolemic shock.

Understanding the baseline risk directs the focus toward signs of perfusion and hydration status.

Analyze each assessment finding to differentiate between expected symptoms and signs of systemic deterioration.

Abdominal cramping, slight memory gaps, and a low-grade temperature are expected or stable findings. Restlessness, tachycardia, and oliguria represent acute systemic changes.

Systemic complications like shock present with compensatory mechanisms (such as tachycardia) and signs of decreased end-organ perfusion.

Prioritize the findings that indicate a threat to circulation and airway/breathing (ABCs).

The increasing heart rate, very low urine output, and acute neurological changes confirm compromised circulation.

Immediate escalation to the RN is required when airway, breathing, or circulation is compromised.

Show answer & explanation

Answer: Notifying the registered nurse immediately about a morning serum potassium level of 2.8 mEq/L (2.8 mmol/L) for a client receiving continuous gastric suction.; Verifying a client's identity by having them state their full name and date of birth before administering a scheduled oral anticoagulant.; Assessing a client's peripheral pulses, skin temperature, and capillary refill distal to a newly placed femoral arterial line.

Answer

The correct risk reduction actions are notifying the registered nurse of the critically low potassium level, verifying the client's identity with two identifiers before medication administration, and assessing the neurovascular status distal to the newly placed arterial line.

Safe clinical judgment and risk reduction require the practical nurse to proactively monitor for complications, adhere to safety protocols, and operate strictly within their designated scope of practice. Reporting a critically low potassium level prevents life-threatening cardiac arrhythmias. Verifying two distinct client identifiers before giving a high-risk medication prevents severe medication administration errors. Assessing the neurovascular status distal to an arterial line ensures early detection of compromised tissue perfusion and ischemia.

Step-by-Step Solution

Analyze the scope of practice and priority safety protocols for a practical nurse.

Identify that the PN must recognize life-threatening physiological trends, escalate abnormal diagnostic findings, and perform fundamental safety checks.

Risk reduction requires proactive monitoring, strict adherence to protocols, and operating within established clinical boundaries.

Evaluate the correct actions for physiological integrity.

Escalating a potassium level of 2.8 mEq/L, verifying two client identifiers, and performing neurovascular checks distal to an arterial line are all necessary, safe, and within scope.

These specific actions directly prevent cardiac emergencies, medication errors, and ischemic tissue damage.

Evaluate the incorrect actions against standard safety and escalation protocols.

Dismissing tachycardia and hypotension as pain, delaying the reporting of a critically low hemoglobin (6.4 g/dL), and administering IV push opioids are unsafe actions.

These actions demonstrate a failure to recognize early shock, a failure to appropriately escalate critical labs, and operating outside the practical nurse's legal scope of practice.

Question 416Question →

A practical nurse (PN) is assisting a healthcare provider with a bedside thoracentesis for a client diagnosed with a large pleural effusion. In what order should the PN perform the following actions to minimize the risk of complications and ensure client safety? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions requires the practical nurse to first verify informed consent, position the client safely to expand the ribs, monitor respiratory status during aspiration, apply an occlusive dressing immediately upon needle withdrawal, and finally ensure a follow-up chest X-ray is completed.

Risk reduction during invasive bedside procedures follows a chronological progression to protect the client. It begins with pre-procedural safety checks (verifying consent), moves to optimal anatomical preparation (upright leaning position) to prevent injury, involves continuous intra-procedural vigilance (oxygen saturation monitoring) for acute complications, utilizes immediate post-procedural site care (occlusive dressing) to prevent air entry, and concludes with post-procedural diagnostic verification (chest X-ray) to definitively rule out a collapsed lung.

Step-by-Step Solution

Verify the informed consent.

The client is legally and ethically cleared for the procedure.

Risk reduction begins with confirming that the client is aware of the procedural risks and has agreed to proceed.

Position the client upright and leaning forward over a table.

The ribs are separated and the pleural space is safely accessible.

This anatomical positioning pushes the diaphragm down and opens the intercostal spaces, heavily reducing the risk of a lung puncture by the needle.

Monitor vital signs and oxygen saturation during the aspiration.

Early signs of respiratory distress are immediately identified.

Removing fluid from the pleural space can cause fluid shifts or accidental lung injury; continuous monitoring ensures rapid intervention if status deteriorates.

Apply a sterile occlusive dressing upon needle removal.

The pleural space is sealed from the outside environment.

An airtight seal prevents air from being sucked into the negative-pressure pleural space, which would cause a collapsed lung.

Prepare for a post-procedure chest X-ray.

Internal structures are radiologically visualized.

An X-ray is the gold standard for confirming that no iatrogenic pneumothorax occurred during the procedure.

Question 417Question →

A client with a history of congestive heart failure is prescribed daily oral furosemide. During morning rounds, the practical nurse gathers data before administering the medication. The electronic health record displays a morning serum potassium level of $2.8 \text{ mEq/L}$ . The client's current vital signs are: blood pressure $94/56 \text{ mmHg}$ , heart rate $114 \text{ bpm}$ , and respiratory rate $18 \text{ breaths/min}$ . What is the priority action by the nurse?

Withhold the furosemide and immediately report the clinical findings to the supervising registered nurse.

Administer the furosemide as prescribed and document the laboratory results in the client's chart.

Initiate an intravenous potassium replacement protocol before giving the diuretic.

Give the medication, as the borderline vital signs are typical compensatory mechanisms for heart failure.

Show answer & explanation

Answer: Withhold the furosemide and immediately report the clinical findings to the supervising registered nurse.

Answer

The most appropriate action is to withhold the scheduled furosemide and report the critical potassium level and vital signs to the registered nurse.

Furosemide is a potent loop diuretic that causes the kidneys to excrete excess fluid along with essential electrolytes, particularly potassium. A serum potassium level of 2.8 mEq/L indicates significant hypokalemia (normal range is 3.5 to 5.0 mEq/L). Furthermore, the client's rapid heart rate (114 bpm) and low blood pressure (94/56 mmHg) are early clinical indicators of hypovolemia (fluid volume deficit). Administering the medication under these conditions could induce severe shock or fatal cardiac dysrhythmias. Therefore, the priority and safest action for a practical nurse is to withhold the dose and immediately notify the registered nurse or healthcare provider.

Step-by-Step Solution

Evaluate the laboratory data.

The client's serum potassium is

2.8 \text{ mEq/L}

Normal serum potassium is

3.5

5.0 \text{ mEq/L}

. A level of

2.8 \text{ mEq/L}

indicates severe hypokalemia.

Evaluate the client's vital signs.

The blood pressure is

94/56 \text{ mmHg}

and the heart rate is

114 \text{ bpm}

Tachycardia and relative hypotension are early compensatory signs of fluid volume deficit (hypovolemia).

Analyze the pharmacological effects of the prescribed medication.

Furosemide is a potassium-wasting loop diuretic.

Administering furosemide will further deplete both the body's fluid volume and serum potassium levels.

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

The nurse must withhold the medication and escalate the findings.

A practical nurse must advocate for client safety by holding contraindicated medications and communicating critical data to the directing registered nurse or provider.

Question 418Question →

A practical nurse is caring for a client with a history of heart failure who is scheduled to receive a routine morning dose of oral furosemide. The client's morning basic metabolic panel reveals a serum potassium level of 2.7 mEq/L (mmol/L). During data collection, the client reports feeling generalized muscle weakness, and the practical nurse notes an irregular apical pulse of 106 beats per minute. What is the most appropriate action for the practical nurse to take?

Administer the furosemide as prescribed and document the laboratory results in the medical record.

Instruct the client to remain on strict bed rest and reassess the borderline tachycardia in one hour.

Withhold the morning dose of furosemide and immediately alert the supervising registered nurse.

Independently obtain a bag of intravenous potassium chloride and initiate a continuous infusion.

Show answer & explanation

Answer: Withhold the morning dose of furosemide and immediately alert the supervising registered nurse.

Answer

The correct action is to withhold the morning dose of furosemide and immediately notify the registered nurse.

The client's serum potassium level of 2.7 mEq/L is critically low (normal range is typically 3.5 to 5.0 mEq/L). Furosemide is a loop diuretic that causes potassium excretion. Administering this medication would further lower the potassium level, increasing the risk of life-threatening cardiac dysrhythmias, which are already suggested by the client's irregular heart rate and muscle weakness. The practical nurse must safely withhold the drug and escalate this critical finding to the registered nurse or healthcare provider to reduce risk potential.

Step-by-Step Solution

Analyze the laboratory results against normal reference ranges.

The serum potassium level of 2.7 mEq/L is critically low (normal is 3.5 to 5.0 mEq/L).

Identifying abnormal laboratory values is essential to determine the client's current physiological stability.

Evaluate the clinical findings in the context of the laboratory results.

The client's muscle weakness and irregular tachycardia are classic clinical manifestations of severe hypokalemia.

Correlating lab data with physical symptoms confirms the client is experiencing adverse physiological effects.

Determine the pharmacological impact of the scheduled medication.

Furosemide is a loop diuretic that promotes the excretion of potassium in the urine.

Administering this medication would further deplete the client's already critical potassium levels.

Select the safest nursing intervention based on the practical nurse's scope of practice.

The practical nurse must withhold the contraindicated medication and escalate the critical findings to the registered nurse or provider.

Preventing harm by holding the drug and ensuring a higher level of care is initiated fulfills the requirement to reduce risk potential.

Question 419Question →

A practical nurse is assigned to care for a client who is prescribed oral levofloxacin, subcutaneous regular insulin, and an intravenous (IV) push dose of ondansetron. The client's morning laboratory results reveal a serum potassium level of $2.9\text{ mEq/L}$ . Which of the following actions are appropriate for the practical nurse to take? Select all that apply.

Select all that apply

Request that the registered nurse administer the intravenous push ondansetron.

Administer the intravenous push ondansetron slowly over

2

minutes to prevent adverse effects.

Report the morning serum potassium result to the registered nurse or healthcare provider immediately.

Administer the subcutaneous regular insulin as scheduled because it does not affect the potassium level.

Verify the client's identity using two distinct identifiers prior to any medication administration.

Scan the client's identification band immediately after the client has swallowed the oral medication.

Show answer & explanation

Answer: Request that the registered nurse administer the intravenous push ondansetron.; Report the morning serum potassium result to the registered nurse or healthcare provider immediately.; Verify the client's identity using two distinct identifiers prior to any medication administration.

Answer

The appropriate actions are to request the registered nurse to administer the IV push medication, report the critical potassium level immediately, and verify the client's identity using two identifiers prior to any administration.

The correct actions prioritize client safety and adhere to the practical nurse scope of practice. Requesting the registered nurse to administer the IV push medication is correct because IV push administration requires advanced clinical judgment outside the practical nurse's scope. Reporting the serum potassium level of

2.9\text{ mEq/L}

is correct because this is a critical value (normal is

3.5\text{ to }5.0\text{ mEq/L}

) requiring prompt intervention, and administering the scheduled insulin would worsen this hypokalemia. Verifying the client's identity using two distinct identifiers prior to administration is a fundamental standard of medication safety.

Step-by-Step Solution

Analyze the practical nurse scope of practice regarding the prescribed medication routes.

The practical nurse can administer oral and subcutaneous medications, but intravenous (IV) push medications require a registered nurse.

To ensure care is delegated and provided within legal and safety boundaries.

Evaluate the provided morning laboratory results.

The serum potassium level is

2.9\text{ mEq/L}

, which indicates significant hypokalemia (normal range:

3.5\text{ to }5.0\text{ mEq/L}

To identify any contraindications or need for immediate medical intervention before giving scheduled medications.

Assess the relationship between the prescribed medications and the abnormal laboratory value.

Regular insulin causes potassium to shift into cells, which would dangerously exacerbate the client's hypokalemia. The medication must be withheld and the lab value reported.

To prevent iatrogenic harm from medication administration.

Apply standard medication administration safety principles.

Two distinct client identifiers must always be verified before, not after, administering any medication.

To adhere to the standard rights of medication administration and prevent errors.

Question 420Question →

An older adult client with a history of congestive heart failure and chronic bronchitis is receiving inpatient care. The practical nurse observes that the client, who was alert and oriented two hours prior, has suddenly become highly agitated, is attempting to climb over the bed rails, and is unable to answer simple questions. Which of the following actions should the practical nurse prioritize?

Explain to the family that sudden confusion is an expected reaction to hospitalization for older adults.

Administer the prescribed as-needed analgesic to help relieve the client's severe agitation.

Apply a pulse oximeter to evaluate the client's current oxygen saturation level.

Place physical restraints on the client immediately to prevent a potential fall from the bed.

Show answer & explanation

Answer: Apply a pulse oximeter to evaluate the client's current oxygen saturation level.

Answer

The practical nurse should prioritize applying a pulse oximeter to evaluate the client's current oxygen saturation level.

The correct action is to apply a pulse oximeter. In clinical practice, sudden onset of restlessness, agitation, or confusion—especially in a client with cardiopulmonary comorbidities—is one of the earliest signs of hypoxia. Using the ABC (Airway, Breathing, Circulation) framework, the nurse must prioritize assessing respiratory status before implementing any other interventions.

Step-by-Step Solution

Identify the acute change in the client's condition.

The client has transitioned from alert and oriented to highly agitated and confused within a short timeframe.

Recognizing a sudden change in mental status is the first step in identifying a physiological decompensation.

Apply the ABC (Airway, Breathing, Circulation) priority framework to the client's symptoms and history.

The client has a history of congestive heart failure and chronic bronchitis, putting them at high risk for respiratory compromise.

In clients with cardiopulmonary disease, sudden restlessness and confusion are classic early indicators of hypoxia.

Select the intervention that addresses the highest priority physiological need.

Assessing oxygenation via pulse oximetry provides immediate data on the 'Breathing' component of the ABCs.

Before treating symptoms with medications or restraints, the underlying life-threatening cause must be investigated.
