Show answer & explanation

Answer: Withholds a scheduled dose of oral potassium chloride and notifies the registered nurse (RN) after noting a morning serum potassium level of 5.9 mEq/L.; Administers scheduled oral levothyroxine to a client on an empty stomach, 30 to 60 minutes before the breakfast tray arrives.; Reinforces dietary teaching for a client prescribed oral warfarin by reviewing a list of foods high in vitamin K provided by the RN.

Answer

The correct actions include withholding the potassium dose due to an elevated lab value and notifying the RN, administering levothyroxine on an empty stomach, and reinforcing established dietary teaching for warfarin.

Safe pharmacological practice within the PN scope involves verifying pertinent laboratory values before administration to prevent toxicity, ensuring the correct timing of medications like levothyroxine for maximum efficacy, and actively reinforcing educational plans previously established by the RN.

Step-by-Step Solution

Evaluate each action against medication safety protocols and the practical nurse (PN) scope of practice.

Identified which actions reflect safe practices and which represent scope or safety violations.

Safe pharmacological therapy requires adherence to both correct administration techniques and legal scope limitations.

Identify correct medication administration practices.

Withholding potassium when levels are high (5.9 mEq/L) and giving levothyroxine on an empty stomach are correct pharmacological interventions.

These actions prevent dangerous drug toxicity and ensure optimal medication absorption.

Analyze delegation and teaching responsibilities.

Reinforcing an RN-developed teaching plan is within the PN scope. However, initiating and titrating IV insulin is beyond the PN scope.

PNs support the primary RN teaching plan but do not independently manage high-risk, titratable continuous IV infusions.

Assess client identification and adverse reaction monitoring protocols.

Asking a family member for patient ID is unsafe; confusion after opioid administration must be reported as a potential adverse effect, not normal aging.

Strict adherence to two independent patient identifiers is mandatory, and acute changes in mentation always indicate a need for further assessment for drug toxicity.

Key Concept

Safe medication administration and adherence to the Practical Nurse (PN) scope of practice, which includes monitoring for adverse effects, checking relevant lab values prior to administration, and reinforcing established client education.

Question 442Question →

While preparing morning treatments on a telemetry unit, a licensed practical nurse checks the latest laboratory values for a client who takes warfarin sodium daily for atrial fibrillation. The laboratory report indicates an International Normalized Ratio (INR) of 5.5. What is the appropriate nursing action concerning the morning dose of this anticoagulant?

Deliver the ordered dose and observe the client for hematuria or ecchymosis.

Reduce the amount of medication administered to safely lower the coagulation level.

Hold the scheduled dose and urgently report the elevated value to the primary registered nurse.

Administer the standard dose but advise the client to use a soft-bristled toothbrush.

Show answer & explanation

Answer: Hold the scheduled dose and urgently report the elevated value to the primary registered nurse.

Answer

Hold the scheduled dose and urgently report the elevated value to the primary registered nurse.

The therapeutic INR range for a client on warfarin therapy is typically 2.0 to 3.0. An INR of 5.5 is critically high and indicates a significant risk for spontaneous bleeding. The LPN's scope of practice requires recognizing this critical laboratory value, withholding the medication that would exacerbate the condition, and immediately reporting the finding to the supervising registered nurse or healthcare provider for further medical orders.

Step-by-Step Solution

Identify the client's current medication and the corresponding laboratory result.

The client is taking warfarin, an anticoagulant, and has an INR of 5.5.

Evaluating relevant laboratory values prior to medication administration is essential for client safety.

Compare the client's INR to the expected therapeutic range for warfarin.

The normal therapeutic INR range for a client with atrial fibrillation is 2.0 to 3.0. An INR of 5.5 is critically high.

Recognizing a supratherapeutic level determines whether the medication is safe to administer.

Determine the appropriate nursing intervention based on the critical laboratory finding and the LPN scope of practice.

The nurse must hold the medication to prevent hemorrhage and immediately escalate the finding to the supervising registered nurse.

Administering the drug would increase the bleeding risk, and altering dosages independently is outside the LPN scope of practice.

Key Concept

Recognizing critical laboratory values related to pharmacological therapies and adhering to pre-administration withholding criteria within the LPN scope of practice.

Question 443Question →

A practical nurse reviews the morning electronic health record for a client with end-stage renal disease who is awaiting their scheduled afternoon hemodialysis treatment. The client's serum potassium level is reported at 6.8 mEq/L (6.8 mmol/L). The client is currently resting quietly in bed and denies any physical distress. Which action should the practical nurse take first?

Report the laboratory results to the registered nurse immediately for prompt medical evaluation.

Document the elevated potassium level as an expected baseline finding prior to a dialysis treatment.

Direct the unlicensed assistive personnel to independently perform and interpret a 12-lead electrocardiogram.

Prioritize the assessment of the client's arteriovenous fistula site for a palpable thrill and audible bruit.

Show answer & explanation

Answer: Report the laboratory results to the registered nurse immediately for prompt medical evaluation.

Answer

The correct action is to immediately report the critical laboratory results to the registered nurse so that prompt medical evaluation and emergency treatment can be initiated.

The correct answer addresses the immediate physiological threat. A potassium level of 6.8 mEq/L is critically high and severely alters myocardial cell depolarization. This places the client at imminent risk for ventricular fibrillation or cardiac arrest. The practical nurse must immediately notify the registered nurse so that emergency interventions can be initiated.

Step-by-Step Solution

Evaluate the reported laboratory value against normal reference ranges.

The client's serum potassium is 6.8 mEq/L. The normal reference range is 3.5 to 5.0 mEq/L.

Identifying abnormal laboratory values is the first step in recognizing potential physiological risks.

Analyze the clinical implications of the abnormal finding in the context of the client's condition.

Severe hyperkalemia (greater than 6.5 mEq/L) can cause fatal cardiac dysrhythmias, regardless of the client's lack of physical symptoms.

Understanding the severity of the complication guides prioritization.

Determine the appropriate scope of practice and escalation protocol.

The practical nurse must immediately notify the registered nurse or healthcare provider to initiate emergency treatment protocols.

Critical lab values that pose an immediate threat to life require rapid escalation outside the independent scope of the practical nurse.

Question 444Question →

A practical nurse is preparing to administer 10 units of regular insulin and 15 units of NPH insulin subcutaneously to a client with type 2 diabetes mellitus. Arrange the steps for preparing this medication in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for mixing insulins is: 1) Roll the NPH vial, 2) Inject air into NPH, 3) Inject air into regular, 4) Withdraw regular insulin, 5) Withdraw NPH insulin.

When mixing intermediate-acting (NPH, cloudy) and short-acting (regular, clear) insulins, the standard sequence 'clear before cloudy' prevents the contamination of the short-acting insulin with the longer-acting insulin. The nurse must first gently roll the NPH vial to resuspend the particles. Next, air must be injected into both vials to equalize pressure, starting with the NPH vial to ensure the needle does not inadvertently carry NPH insulin into the regular insulin vial. Finally, the regular insulin is drawn up, followed by the NPH insulin.

Step-by-Step Solution

Identify the types of insulins being mixed.

NPH is an intermediate-acting (cloudy) insulin, and regular is a short-acting (clear) insulin.

Understanding the medication characteristics dictates the 'clear before cloudy' safety rule.

Sequence the air injections.

Air is injected into the NPH vial first, followed by the regular insulin vial.

This equalizes pressure in both vials while ensuring the needle does not touch the cloudy insulin before entering the clear insulin vial.

Sequence the insulin withdrawal.

Regular insulin is withdrawn first, followed by the NPH insulin.

Drawing the clear insulin first prevents accidental contamination of the regular insulin vial with the longer-acting NPH insulin.

Question 445Question →

A 79-year-old client is admitted to the medical unit for treatment of a severe urinary tract infection. Upon entering the room, the practical nurse (PN) finds the client highly agitated, disoriented to place, and pulling at their intravenous tubing. Current vital signs reveal a temperature of 101.4°F (38.5°C), heart rate of 115 beats/min, respiratory rate of 26 breaths/min, and blood pressure of 92/54 mmHg (admission blood pressure was 130/76 mmHg). Which action should the PN take first?

Immediately report the clinical findings to the supervising registered nurse (RN) for further evaluation.

Note the acute confusion in the electronic health record as a normal age-related response to hospitalization.

Give a PRN oral sedative to safely manage the sudden agitation and prevent a potential fall.

Proceed with the standard plan of care, as these mild vital sign fluctuations are anticipated with an infection.

Show answer & explanation

Answer: Immediately report the clinical findings to the supervising registered nurse (RN) for further evaluation.

Answer

The practical nurse should immediately report the changes in vital signs and mental status to the registered nurse.

The correct action identifies that the client is exhibiting classic signs of systemic inflammatory response and potential septic shock (hypotension, tachycardia, tachypnea, and fever) combined with altered mental status. In the practical nursing role, recognizing this physiological instability requires immediate escalation to the RN or provider for rapid medical intervention.

Step-by-Step Solution

Analyze the client's current clinical presentation against their baseline.

The client exhibits new-onset agitation, disorientation, tachycardia (115 beats/min), tachypnea (26 breaths/min), and a substantial drop in blood pressure (92/54 mmHg).

Identifying abnormal findings and vital sign trends is the first step in recognizing physiological deterioration.

Correlate the assessment data with the client's primary diagnosis.

The combination of a known infection with fever, hypotension, and altered mentation points strongly toward sepsis or early septic shock.

Understanding the pathophysiology of the condition allows the nurse to anticipate severe complications.

Determine the priority nursing action based on the PN scope of practice.

The PN must immediately escalate these critical findings to the RN or provider.

Acute hemodynamic instability requires rapid medical intervention (such as fluid resuscitation) and RN-level assessment to stabilize the client's circulation.

A practical nurse (PN) is reviewing the morning laboratory results for a $72$ -year-old client who is scheduled for a computed tomography (CT) scan with intravenous (IV) contrast later this morning. The client was admitted yesterday with community-acquired pneumonia. Which laboratory finding indicates the highest risk for a potential procedure-related complication and should be reported to the registered nurse (RN) immediately?

White blood cell (WBC) count of

14,500/\text{mm}^3

Blood urea nitrogen (BUN) level of

18\text{ mg/dL}

Serum creatinine level of

2.4\text{ mg/dL}

Serum potassium level of

4.1\text{ mEq/L}

Show answer & explanation

Answer: Serum creatinine level of $2.4\text{ mg/dL}$

Answer

Serum creatinine level of

2.4\text{ mg/dL}

IV contrast media is nephrotoxic. A serum creatinine level of

2.4\text{ mg/dL}

is abnormally high (normal is approximately

0.6-1.2\text{ mg/dL}

) and indicates impaired renal function. Administering contrast dye to this client significantly increases the risk of contrast-induced nephropathy (acute kidney injury). The PN must report this to the RN immediately so the provider can modify the diagnostic plan.

Step-by-Step Solution

Analyze the scheduled procedure and its associated risks.

The client is scheduled for a CT scan with IV contrast. IV contrast dye is nephrotoxic and can cause contrast-induced nephropathy.

Identifying the specific risks of a procedure is essential for anticipating complications and ensuring client safety.

Evaluate the laboratory results to determine if any values indicate a high risk for the procedure.

The serum creatinine level of

2.4\text{ mg/dL}

is significantly elevated above the normal range (typically

0.6-1.2\text{ mg/dL}

), indicating impaired renal function.

Administering nephrotoxic contrast dye to a client with preexisting renal impairment poses a severe risk of acute kidney injury.

Determine the appropriate nursing action based on the LPN scope of practice.

The PN must immediately report the elevated creatinine to the RN or healthcare provider.

The provider must be notified to potentially cancel the scan, order intravenous hydration, or utilize an imaging modality without contrast to protect the client's kidneys.

Question 447Question →

A practical nurse is preparing to administer scheduled morning medications to a client diagnosed with heart failure. The medication administration record includes a prescription for oral digoxin. Upon reviewing the client's electronic health record, the nurse notes a morning serum potassium level of 2.9 mEq/L. Based on these findings, which of the following actions should the practical nurse take first?

Administer the scheduled digoxin and document the abnormal potassium level in the client's medical record.

Recalculate the digoxin dosage based on the client's current weight to compensate for the electrolyte imbalance.

Withhold the dose of digoxin and promptly notify the registered nurse about the laboratory result.

Independently initiate an intravenous potassium replacement infusion before giving the oral digoxin.

Show answer & explanation

Answer: Withhold the dose of digoxin and promptly notify the registered nurse about the laboratory result.

Answer

The practical nurse should withhold the dose of digoxin and promptly notify the registered nurse about the critical laboratory result.

The normal serum potassium range is 3.5 to 5.0 mEq/L. A level of 2.9 mEq/L indicates severe hypokalemia. Because hypokalemia strongly predisposes a client to digoxin toxicity, the safest and most appropriate action for the practical nurse is to withhold the dose and escalate the critical finding to the registered nurse or healthcare provider for further evaluation.

Step-by-Step Solution

Evaluate the client's laboratory results against normal reference ranges.

The serum potassium level is 2.9 mEq/L, which is significantly below the normal range of 3.5 to 5.0 mEq/L (hypokalemia).

Identifying abnormal laboratory values is an essential pre-administration safety check.

Correlate the abnormal laboratory finding with the prescribed medication.

Hypokalemia is identified as a major risk factor that precipitates digoxin toxicity, even if the digoxin level itself is within a normal range.

Understanding drug-lab interactions is necessary to prevent severe adverse pharmacological events, such as life-threatening cardiac arrhythmias.

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

The safest and legally correct action is to withhold the contraindicated medication and immediately report the finding to the supervising RN or healthcare provider.

A practical nurse must advocate for client safety by not administering harmful medications and by escalating critical findings to higher-level providers for medical intervention.

Question 448Question →

A healthcare provider prescribes amoxicillin oral suspension for a toddler weighing $14\text{ kg}$ to treat acute otitis media. The prescription is for $30\text{ mg/kg/day}$ divided into two equal doses administered every 12 hours. The medication label indicates a concentration of $250\text{ mg}/5\text{ mL}$ . How many mL will the practical nurse administer for one dose? Record your answer to the nearest tenth. Do not include units in your answer.

Show answer & explanation

Answer: 4.2

Answer

4.2

To find the correct volume for one dose, first calculate the total daily requirement:

14\text{ kg} \times 30\text{ mg/kg/day} = 420\text{ mg/day}

. Next, divide this by

2

for the every-12-hour dosing schedule:

420\text{ mg/day} \div 2 = 210\text{ mg/dose}

. Finally, determine the liquid volume using the supplied concentration:

\frac{210\text{ mg}}{250\text{ mg}} \times 5\text{ mL} = 4.2\text{ mL}

Step-by-Step Solution

Determine the total daily dose of the medication.

420\text{ mg/day}

The prescription is weight-based at

30\text{ mg/kg/day}

. Multiplying the weight (

14\text{ kg}

) by the dose per kg (

30\text{ mg}

) gives the total daily requirement.

Calculate the amount of medication needed for a single dose.

210\text{ mg/dose}

The daily dose is divided into two equal doses administered every 12 hours. Dividing the daily total (

420\text{ mg}

) by

2

gives the single dose amount.

Calculate the volume of liquid required for the single dose.

4.2\text{ mL}

Using the dosage formula

\frac{\text{Desired Dose}}{\text{Available Dose}} \times \text{Volume} = \frac{210\text{ mg}}{250\text{ mg}} \times 5\text{ mL} = 4.2\text{ mL}

Show answer & explanation

Answer: Institute bleeding precautions by providing a soft-bristle toothbrush and an electric razor.; Monitor the client's urine and stool output for the presence of occult or frank blood.; Evaluate the client promptly for any sudden onset of chest pain, tachycardia, and dyspnea.

Answer

The practical nurse should institute bleeding precautions, monitor output for the presence of blood, and evaluate the client promptly for sudden chest pain, tachycardia, and dyspnea.

To reduce risk potential, the PN must prioritize interventions that address the most significant threats to the client: bleeding (due to heparin) and pulmonary embolism (due to the DVT). Implementing bleeding precautions (electric razor, soft toothbrush) and monitoring excreta for occult blood directly mitigate and detect hemorrhage. Assessing for sudden chest pain and shortness of breath ensures rapid detection of a pulmonary embolism, which is a medical emergency.

Step-by-Step Solution

Identify the primary clinical risks associated with the client's diagnosis and prescribed treatment.

The client is at high risk for hemorrhage due to the continuous heparin infusion and at risk for a pulmonary embolism (PE) due to the presence of a deep vein thrombosis.

Recognizing specific risk factors guides the nurse in selecting appropriate targeted assessments and preventive interventions.

Evaluate each nursing action against the identified risks and the established LPN/LVN scope of practice.

Providing an electric razor, monitoring stool/urine for blood, and assessing for signs of a PE are appropriate risk reduction strategies within the PN scope.

These actions directly mitigate the risk of bleeding and ensure early detection of life-threatening complications.

Identify and eliminate actions that are unsafe, outside the scope of practice, or represent clinical misinterpretations.

Administering IV push medications, withholding therapy for a normal platelet count, and dismissing early signs of shock are incorrect and unsafe actions.

Adhering to scope of practice and accurately interpreting objective clinical data are essential components of safe client care.

The electronic health record indicates the client's morning serum potassium level is $6.1\text{ mEq/L}$ . What is the most appropriate action for the practical nurse to take?

Withhold the spironolactone and promptly report the laboratory finding to the registered nurse.

Administer the medication, as this laboratory value represents an expected finding for a client taking a diuretic.

Verify the client's identity using two identifiers and administer the medication as prescribed.

Assess the client's blood pressure and administer the dose if the systolic reading is greater than

90\text{ mm Hg}

Show answer & explanation

Answer: Withhold the spironolactone and promptly report the laboratory finding to the registered nurse.

Answer

The practical nurse should withhold the spironolactone and immediately report the elevated potassium level to the registered nurse.

Spironolactone is a potassium-sparing diuretic. A normal serum potassium level ranges from

3.5

5.0\text{ mEq/L}

. A level of

6.1\text{ mEq/L}

indicates severe hyperkalemia, which can lead to life-threatening cardiac dysrhythmias. Therefore, the safest and most appropriate action within the PN scope of practice is to withhold the medication and notify the RN immediately.

Step-by-Step Solution

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

The serum potassium level is

6.1\text{ mEq/L}

, which is significantly above the normal range of

3.5

5.0\text{ mEq/L}

Identifying normal versus abnormal laboratory values is a critical safety step before medication administration.

Correlate the laboratory finding with the prescribed medication's mechanism of action.

Spironolactone is recognized as a potassium-sparing diuretic.

Understanding pharmacodynamics reveals that administering this drug will further elevate the already critical potassium level.

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

The medication must be withheld and the critical finding escalated to the supervising registered nurse.

The PN must ensure client safety by preventing the administration of a contraindicated drug and communicating critical data promptly.

Answer: Notify the registered nurse (RN) immediately about the changes in mental status and vital signs.; Ensure the patency of the client's peripheral intravenous (IV) catheter.; Administer supplemental oxygen as prescribed.

Answer

The correct actions are to notify the registered nurse (RN) immediately about the changes, ensure the patency of the peripheral IV catheter, and administer supplemental oxygen as prescribed.

The correct actions prioritize recognizing and responding to the early signs of hypovolemic shock resulting from severe dehydration. Notifying the RN ensures appropriate escalation and medical intervention, ensuring IV patency prepares the client for necessary rapid fluid resuscitation, and administering oxygen addresses potential tissue hypoxia that is causing the client's new-onset restlessness.

Step-by-Step Solution

Analyze the client's history and presenting clinical data.

The client has a history of severe fluid loss (vomiting and diarrhea). Current findings reveal new-onset confusion, tachycardia (108 bpm), and a relative drop in blood pressure from 138/78 to 104/62 mm Hg.

Comparing current data against the client's baseline is essential to accurately identify physiological deterioration.

Correlate the assessment findings to a potential physiological complication.

The combination of significant fluid loss, borderline abnormal vital signs, and acute mental status changes indicates the early compensatory stages of hypovolemic shock.

Connecting clinical manifestations to their underlying pathophysiological cause guides nursing prioritization and intervention.

Select the most appropriate interventions within the practical nurse (PN) scope of practice.

The PN must escalate the findings to the RN, secure IV access for anticipated fluid resuscitation, and administer oxygen to support tissue perfusion.

Show answer & explanation

Answer: Obtain a pulse oximetry reading to check oxygen saturation.

Answer

Obtain a pulse oximetry reading to check oxygen saturation.

Sudden restlessness, agitation, and confusion in a postoperative client are primary indicators of underlying physiological compromise, most commonly hypoxia or early hemorrhagic shock. The borderline elevated heart rate and respiratory rate further support a compensatory physiological response. The priority action within the practical nursing scope is to immediately collect focused data on the client's respiratory and oxygenation status to identify or rule out hypoxia before implementing other measures.

Step-by-Step Solution

Analyze the client's new-onset symptoms.

The client is exhibiting sudden restlessness, confusion, borderline tachycardia (114 bpm), and tachypnea (24 breaths/min).

Identifying acute deviations from the baseline status is the crucial first step in clinical judgment.

Correlate symptoms with potential postoperative physiological complications.

Sudden restlessness and altered mental status in a postoperative client are primary early indicators of hypoxia or impaired perfusion.

Physiological adaptation issues must be investigated before assuming psychological or cognitive causes for confusion.

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

Gathering specific data regarding the client's respiratory status directly addresses the most life-threatening potential cause.

Airway and Breathing (ABCs) always take priority in emergent or acute status changes.

Answer: Verify the client's identity using two distinct identifiers prior to administering an oral antibiotic.; Monitor the client's peripheral intravenous (IV) site for redness or swelling during a piggyback antibiotic infusion.; Reinforce the registered nurse's teaching regarding the common adverse effects of the prescribed medications.

Answer

The appropriate actions are: verifying the client's identity using two distinct identifiers, monitoring the peripheral IV site during the infusion, and reinforcing teaching regarding medication adverse effects.

The correct actions align with the practical nurse's scope of practice and strict medication administration standards. Verifying two unique identifiers ensures the medication is given to the correct client. Monitoring an IV site during a piggyback infusion is a required safety check to detect infiltration or phlebitis early. Reinforcing teaching that was initially provided by the registered nurse or provider is a primary educational responsibility of the practical nurse.

Step-by-Step Solution

Analyze the clinical scenario and the role of the nurse.

The scenario involves a practical nurse caring for a client receiving pharmacological therapies for an acute infection.

Understanding the client's condition (acute infection) and the nurse's specific scope of practice (PN) is necessary to evaluate the appropriateness of each intervention.

Evaluate each option based on established medication safety principles.

Verifying two identifiers promotes safety. Leaving medications at the bedside violates the rights of medication administration.

Adhering to the rights of medication administration prevents errors and ensures client safety.

Evaluate each option against the legal scope of practice for a practical nurse.

Reinforcing teaching and monitoring an IV site are within the PN scope. Administering an IV push medication is generally outside the PN scope.

Delegated tasks must match the nurse's licensure, education, and competency level.

Evaluate options involving pharmacological contraindications.

Administering a live-attenuated vaccine is inappropriate for a client currently suffering from a severe acute illness.

Recognizing contraindications prevents serious adverse therapeutic reactions.

Answer

Notify the registered nurse (RN) immediately regarding the changes in vital signs

The client's shifting vital signs (tachycardia and hypotension) combined with a history of severe diarrhea indicate the onset of hypovolemic shock. Because this is a potentially life-threatening complication that requires advanced clinical assessment and medical interventions (such as fluid boluses), the practical nurse must prioritize immediately escalating these findings to the registered nurse.

Step-by-Step Solution

Analyze the client's vital sign trends over the past four hours.

The heart rate increased from

84

112

beats per minute (tachycardia), and the blood pressure decreased from

118/76

100/62

mm Hg (hypotension).

Comparing current vital signs to baseline is essential for identifying physiological deterioration.

Correlate the vital sign changes with the client's admitting diagnosis.

The client has severe gastroenteritis with prolonged diarrhea, placing them at high risk for significant fluid volume deficit.

Understanding the underlying pathology helps anticipate complications such as severe dehydration and hypovolemia.

Determine the priority nursing intervention based on the practical nurse scope of practice.

The practical nurse must immediately communicate these findings to the registered nurse.

The vital sign trends indicate early hypovolemic shock, which requires advanced assessment, provider notification, and potentially rapid fluid resuscitation that exceeds the practical nurse's independent scope.

A practical nurse (PN) is preparing to administer a scheduled dose of oral metoprolol to an adult client. Prior to administration, the PN assesses the following vital signs: blood pressure $92/58\text{ mm Hg}$ , heart rate $54\text{ beats/minute}$ , and respiratory rate $16\text{ breaths/minute}$ . Which action should the PN take?

Withhold the medication and report the vital signs to the registered nurse.

Document the vital signs and administer the medication, assuming these are expected resting values.

Independently administer half of the prescribed dose to prevent a further decrease in the heart rate.

Administer the medication and elevate the head of the bed to promote airway clearance.

Show answer & explanation

Answer: Withhold the medication and report the vital signs to the registered nurse.

Answer

The practical nurse should withhold the metoprolol and immediately report the bradycardia and hypotension to the registered nurse.

Metoprolol is a beta-adrenergic blocking agent that lowers heart rate and blood pressure. Standard safety parameters dictate that this medication should be withheld if the client's heart rate is below

60\text{ beats/minute}

or if the systolic blood pressure is below

100\text{ mm Hg}

. Because this client exhibits both bradycardia and hypotension, the safe and legally appropriate action for the practical nurse is to hold the dose and notify the registered nurse for further evaluation.

Step-by-Step Solution

Analyze the client's vital signs against the expected parameters for metoprolol administration.

The heart rate is

54\text{ beats/minute}

(bradycardia) and blood pressure is

92/58\text{ mm Hg}

(hypotension).

Metoprolol is a beta-blocker that decreases heart rate and blood pressure; administering it to a client with already low parameters is dangerous.

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

The medication must be withheld.

Standard nursing safety parameters require withholding beta-blockers if the heart rate is less than

60\text{ beats/minute}

or systolic blood pressure is less than

100\text{ mm Hg}

Identify the required follow-up communication.

The findings must be reported to the registered nurse or healthcare provider.

The practical nurse must escalate abnormal assessment data that affects medication administration for further clinical judgment.

Question 456Question →

While performing a routine assessment for a client who is 3 days postoperative from an exploratory laparotomy, a practical nurse observes a loop of bowel protruding through the abdominal incision after the client forcefully sneezes. The client reports a sudden 'popping' feeling. Arrange the following emergency interventions in the correct priority sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first call for assistance without leaving the client, then position the client to reduce abdominal tension, next cover the protruding organs with moist sterile dressings, and finally assess vital signs to monitor for shock.

Wound evisceration is a surgical emergency. The nurse's first action is to stay with the client and call for immediate assistance. Next, placing the client in a low Fowler's position with knees flexed reduces tension on the abdominal wall, preventing further evisceration. Once supplies are brought to the room, the nurse covers the protruding organs with sterile, saline-soaked dressings to prevent necrosis. Finally, the nurse obtains vital signs to monitor for shock while preparing the client for emergency surgery.

Step-by-Step Solution

Remain at the bedside and activate the emergency call system to request assistance.

Help is mobilized without leaving the client unattended.

Wound evisceration is a medical emergency requiring the RN and surgeon. The nurse must not leave the client alone.

Position the client in a low Fowler's position with the knees flexed.

Tension on the abdominal wall is reduced.

Bending the knees and slightly elevating the head relaxes the abdominal muscles, preventing further evisceration.

Apply sterile dressings moistened with sterile 0.9% sodium chloride over the exposed bowel.

The exposed bowel is protected from drying and infection.

Keeping the organs moist is critical to prevent tissue necrosis until the client can be returned to the operating room.

Obtain a complete set of vital signs to evaluate for impending hypovolemic shock.

Baseline physiological stability is determined.

Evisceration can lead to rapid fluid loss and shock. Vital signs guide further emergency interventions and surgical preparation.

An unlicensed assistive personnel (UAP) informs the practical nurse (PN) that a 77-year-old client is suddenly agitated and disoriented. The client had a surgical repair of a fractured femur 24 hours ago. Upon assessment, the PN notes the client has a respiratory rate of 26 breaths/minute, a heart rate of 109 beats/minute, and a blood pressure of 102/64 mm Hg. Which of the following actions should the PN take? Select all that apply.

Select all that apply

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

Report the sudden change in mental status and vital signs to the registered nurse (RN).

Inspect the surgical site and dressing for excessive drainage or bleeding.

Document the acute confusion as a normal age-related response to hospitalization.

Monitor the vital signs at the next scheduled interval since the values are borderline.

Administer the prescribed PRN opioid analgesic to treat the underlying cause of agitation.

Show answer & explanation

Answer: Apply a pulse oximeter to evaluate the client's oxygen saturation.; Report the sudden change in mental status and vital signs to the registered nurse (RN).; Inspect the surgical site and dressing for excessive drainage or bleeding.

Answer

The correct actions are to apply a pulse oximeter, report the findings to the RN, and inspect the surgical site for bleeding.

The client is demonstrating early signs of acute physiological compromise, which could indicate hypoxia, fat embolism, or hypovolemic shock. Applying a pulse oximeter addresses the immediate need to evaluate respiratory status (ABCs). Inspecting the surgical site is essential to identify potential hemorrhage as a cause for the vital sign changes. Because this represents an acute, unstable change in condition, the PN must immediately report these findings to the RN to facilitate prompt medical intervention.

Step-by-Step Solution

Analyze the client's clinical presentation.

The client has new-onset agitation, disorientation, tachypnea (26 breaths/min), tachycardia (109 beats/min), and borderline blood pressure (102/64 mm Hg).

Identifying abnormal data and subtle physiological cues is the first step in clinical judgment.

Determine the potential underlying complication.

These findings are early indicators of acute decompensation, such as hypovolemia, hemorrhage, or hypoxia (potentially from a fat embolism), rather than expected postoperative symptoms.

Connecting physiological changes to severe complications guides safe nursing interventions.

Prioritize nursing actions based on ABCs and scope of practice.

The PN must evaluate oxygenation (Breathing/Circulation), assess for bleeding (Circulation), and escalate care to the RN.

Airway, breathing, and circulation take priority in unstable clients, and acute changes must be reported immediately.

Question 458Question →

After receiving the shift handoff report for four assigned clients on a step-down medical unit, which client should the practical nurse (PN) evaluate first?

A client who had a femoral cardiac catheterization 4 hours ago, with a heart rate of 114 bpm, blood pressure of 96/60 mm Hg, and new-onset lower back ache.

A client who underwent an open reduction and internal fixation of the ankle 48 hours ago, requesting medication for pain rated as 7 out of 10.

An older adult client with advanced dementia who is pacing the room and repeatedly asking for their spouse.

A client with severe chronic obstructive pulmonary disease (COPD) who has a resting oxygen saturation of 91% on room air.

Show answer & explanation

Answer: A client who had a femoral cardiac catheterization 4 hours ago, with a heart rate of 114 bpm, blood pressure of 96/60 mm Hg, and new-onset lower back ache.

Answer

The client who had a femoral cardiac catheterization and is exhibiting early signs of shock.

The correct answer is the client recovering from a femoral cardiac catheterization. This client is displaying tachycardia, borderline hypotension, and new-onset back pain, which are classic early signs of a retroperitoneal hemorrhage following a femoral arterial puncture. This represents an acute, life-threatening circulatory compromise (Circulation in ABCs) that requires immediate evaluation and escalation to the registered nurse.

Step-by-Step Solution

Analyze the clinical status of the post-cardiac catheterization client.

The combination of tachycardia, low-normal blood pressure, and new back pain suggests a retroperitoneal hemorrhage.

Airway, Breathing, and Circulation (ABCs) take the highest clinical priority; bleeding compromises circulation.

Analyze the clinical status of the postoperative ankle client.

Postoperative pain is an expected finding 48 hours after bone surgery.

Pain management is a psychosocial and comfort need that does not supersede acute circulatory failure.

Analyze the clinical status of the client with advanced dementia.

Disorientation and pacing are chronic, baseline behaviors for this individual.

Chronic, stable conditions are triaged at a lower priority than acute, newly unstable conditions.

Analyze the clinical status of the client with severe COPD.

An oxygen saturation of 91% is an expected baseline adaptation for a client with severe COPD.

Compensated, expected respiratory findings are a lower priority than an uncompensated acute hemorrhage.

Question 459Question →

An adult client is prescribed iron dextran via intramuscular injection. To prevent tissue irritation and skin staining, the practical nurse utilizes the Z-track technique. Place the steps of this administration technique in the appropriate chronological order, assuming standard pre-administration safety checks and hand hygiene have already been completed.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for administering a Z-track intramuscular injection is to first displace the skin laterally, then insert the needle at a 90-degree angle, slowly inject the medication, hold the needle in place for 10 seconds, and finally withdraw the needle while simultaneously releasing the skin.

The Z-track method relies on misaligning tissue layers prior to injection. By displacing the skin first, inserting the needle, injecting, waiting for dispersion, and then releasing the skin simultaneously as the needle is removed, a broken (zigzag) path is created. This permanently traps the medication in the muscle layer.

Step-by-Step Solution

Identify the purpose of the Z-track method.

The goal is to prevent medication from leaking back into the subcutaneous tissue, which is especially important for irritating or staining medications like iron dextran.

Understanding the physiological goal helps logically sequence the physical actions required.

Determine the initial physical action required to create the 'track'.

The skin and subcutaneous tissue must be displaced laterally before any needle insertion occurs.

If the skin is not displaced first, the needle track will be perfectly straight, defeating the purpose of the technique.

Sequence the insertion and injection steps.

While holding the skin displaced, the needle is inserted at a 90-degree angle, and the medication is injected slowly.

A 90-degree angle ensures intramuscular delivery, and a slow injection minimizes tissue trauma.

Identify the critical pause before removing the needle.

The needle must be held in place for 10 seconds after the injection is complete.

This brief pause allows the medication to begin absorbing into the muscle, reducing the risk of it tracking back up the needle path.

Sequence the final withdrawal step.

The needle is withdrawn and the skin is immediately released.

Releasing the skin shifts the superficial tissue layers back to their original position, breaking the needle track and trapping the medication in the muscle.

Key Concept

The Z-track method is an intramuscular injection technique designed to trap medication in the muscle layer and prevent it from leaking into the subcutaneous tissue, thereby reducing irritation and staining.

A practical nurse (PN) is providing care for a client who is $4$ hours postoperative following a percutaneous coronary intervention (PCI) via the right femoral artery. Which nursing action demonstrates the correct application of risk reduction principles?

Promptly reporting to the registered nurse (RN) that the client's resting heart rate has gradually increased from

76

112

beats/minute.

Bypassing the electronic barcode scanning system to expedite the administration of a scheduled oral antiplatelet medication.

Show answer & explanation

Answer: Promptly reporting to the registered nurse (RN) that the client's resting heart rate has gradually increased from $76$ to $112$ beats/minute.

Answer

The correct action is to promptly report the increasing heart rate to the RN, as it is an early indicator of potential hemorrhage.

An unexplained, gradual increase in heart rate (tachycardia) following a femoral artery catheterization is a classic early sign of internal hemorrhage, such as a retroperitoneal bleed. The practical nurse demonstrates accurate application of risk reduction by recognizing this subtle vital sign change and immediately escalating it to the registered nurse for comprehensive assessment and intervention.

Step-by-Step Solution

Evaluate the client's current clinical data against baseline findings.

The heart rate has increased from

76

112

beats/minute.

Identifying trends in vital signs is crucial for detecting early physiological deterioration.

Correlate the vital sign changes with the client's recent surgical procedure.

The client had a femoral artery puncture, placing them at high risk for internal bleeding (retroperitoneal hemorrhage).

Unexplained, gradual tachycardia is one of the earliest compensatory mechanisms for hypovolemia or occult bleeding.

Determine the appropriate risk-reduction intervention within the PN scope of practice.

The PN must immediately escalate the finding to the supervising RN for further assessment and potential provider notification.

Early escalation allows for rapid medical intervention, preventing the client from progressing into severe hypovolemic shock.
