Question 1

1. Blood pressure 158/90 mm Hg
2. Potassium 4.1 mEq/L
3. Sodium 134 mEq/L
4. Oxygen saturation 87% on room air with positive fluid balance (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key issue is fluid overload, indicated by oxygen saturation 87%, shortness of breath, positive fluid balance, and tachypnea post-surgery. The finding of oxygen saturation 87% on room air with positive fluid balance should be reported because it signals pulmonary edema requiring intervention. Potassium 4.1 mEq/L is normal; sodium 134 mEq/L is normal; blood pressure 158/90 mm Hg is elevated but secondary. The clinical decision-making principle applied is prioritizing oxygenation in overload. This involves reviewing intake/output and saturation. A transferable strategy is to report low saturation and high intake in post-op clients promptly.

Question 2

1. Provide free water at the bedside to correct sodium level slowly
2. Implement seizure precautions and notify the RN of worsening neurologic symptoms with severe hyponatremia (correct answer)
3. Delegate to unlicensed assistive personnel to offer ice chips frequently
4. Teach the client to avoid salty foods to prevent fluid retention

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is severe hyponatremia, with sodium 120 mEq/L and confusion in a client on fluid restriction. Implementing seizure precautions and notifying the RN of worsening neurologic symptoms with severe hyponatremia is the best choice because it addresses seizure risk urgently. Providing free water would exacerbate hyponatremia; delegating ice chips is unsafe; teaching salt avoidance is incorrect. The clinical decision-making principle applied is prioritizing neurological safety in hyponatremia. This involves recognizing confusion as a critical symptom. A transferable strategy is to apply precautions and notify for hyponatremia below 125 mEq/L with symptoms.

Question 3

1. Encourage the client to drink more free water to improve sodium level
2. Implement seizure precautions and notify the RN of symptomatic hyponatremia (correct answer)
3. Delegate to unlicensed assistive personnel to recheck the client's weight
4. Teach the client to avoid foods high in sodium

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hyponatremia, indicated by a sodium level of 122 mEq/L with symptoms of confusion and nausea in a client on furosemide. Implementing seizure precautions and notifying the RN of symptomatic hyponatremia is the best choice because low sodium can lead to neurological complications requiring immediate safety measures. Encouraging more free water would worsen hyponatremia; delegating weight recheck is not urgent; teaching to avoid high-sodium foods is counterproductive. The clinical decision-making principle applied is prioritizing neurological safety in hyponatremia to prevent seizures or coma. This involves recognizing symptoms and escalating care quickly. A transferable strategy is to apply seizure precautions and notify the team for any client with severe hyponatremia and altered mental status.

Question 4

2. Notify the RN immediately and ensure the client remains on continuous cardiac monitoring (correct answer)
3. Recheck the potassium level in 2 hours to confirm the result
4. Delegate to unlicensed assistive personnel to obtain the client's daily weight

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hyperkalemia, with potassium 6.8 mEq/L, weakness, and bradycardia in CKD. Notifying the RN immediately and ensuring the client remains on continuous cardiac monitoring is the best choice because it addresses arrhythmia risk urgently. Teaching salt substitutes is not immediate; rechecking in 2 hours delays care; delegating weight is lower priority. The clinical decision-making principle applied is prioritizing cardiac monitoring in hyperkalemia. This involves recognizing weakness and bradycardia as critical. A transferable strategy is to notify and monitor continuously for potassium above 6.5 mEq/L with symptoms.

Question 5

1. Teach the client to avoid foods high in sodium
2. Encourage increased oral fluids to thin secretions
3. Delegate to unlicensed assistive personnel to obtain a full bed bath to reduce anxiety
4. Slow the intravenous infusion as allowed by the order, elevate the head of the bed, and notify the RN (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key issue is fluid overload, evidenced by new crackles, tachycardia, hypertension, and low oxygen saturation in a client receiving IV fluids. Slowing the intravenous infusion as allowed, elevating the head of the bed, and notifying the RN is the best choice because it reduces further overload and improves breathing urgently. Encouraging oral fluids would worsen the issue; delegating a bath is inappropriate; teaching sodium avoidance is not immediate. The clinical decision-making principle applied is prioritizing respiratory support and fluid rate adjustment for safety. This involves assessing lung sounds and vitals to detect overload early. A transferable strategy is to adjust IV rates and position clients upright while notifying the team in suspected fluid overload.

Question 6

1. Ask unlicensed assistive personnel to provide oral fluids while the nurse completes documentation
2. Provide a low-sodium meal tray to lower sodium level
3. Obtain a urine specimen for specific gravity before starting fluids
4. Start prescribed intravenous isotonic fluids and monitor for improvement in blood pressure (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key issue is hypernatremia and dehydration, indicated by sodium 154 mEq/L, thirst, hypotension, and tachycardia from GI losses.

Providing a low-sodium tray is incorrect; obtaining urine specific gravity delays action; delegating oral fluids is insufficient. The clinical decision-making principle applied is prioritizing fluid replacement in hypovolemia. This involves monitoring vitals for response. A transferable strategy is to initiate IV fluids and reassess in clients with hypernatremia and hypotension.

Question 7

1. Hold all oral intake until potassium normalizes
2. Delegate to unlicensed assistive personnel to obtain a repeat potassium level
3. Teach the client about choosing low-potassium foods at home
4. Notify the RN and obtain an electrocardiogram per facility protocol while continuing cardiac monitoring (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hyperkalemia, with potassium 6.2 mEq/L, numbness, and bradycardia in renal failure. Notifying the RN and obtaining an electrocardiogram per facility protocol while continuing cardiac monitoring is the best choice because it evaluates for arrhythmias urgently. Holding oral intake is insufficient; teaching diet is not immediate; delegating repeat labs delays. The clinical decision-making principle applied is prioritizing ECG assessment in hyperkalemia. This involves recognizing numbness as a symptom. A transferable strategy is to notify and obtain ECG for potassium above 6 mEq/L with symptoms.

Question 8

1. Delegate to unlicensed assistive personnel to obtain orthostatic vital signs first
2. Encourage the client to drink plain water to replace losses
3. Teach the client to avoid potassium-rich foods until diarrhea resolves
4. Administer prescribed potassium replacement and place the client on cardiac monitoring per facility protocol (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hypokalemia, shown by a potassium level of 2.9 mEq/L with muscle cramps and tachycardia from gastroenteritis. Administering prescribed potassium replacement and placing the client on cardiac monitoring per facility protocol is the best choice because hypokalemia can cause arrhythmias needing urgent correction. Encouraging plain water would worsen electrolyte loss; teaching to avoid potassium-rich foods is incorrect; delegating orthostatic vitals delays treatment. The clinical decision-making principle applied is prioritizing electrolyte replacement and cardiac monitoring for safety. This involves assessing symptoms and labs to address life-threatening imbalances first. A transferable strategy is to initiate potassium supplementation and monitoring in clients with significant GI losses and low potassium.

Question 9

1. Administer prescribed antiemetic medication and reassess nausea
2. Ask unlicensed assistive personnel to ambulate the client to the bathroom
3. Obtain a 24-hour diet recall to estimate sodium intake
4. Start prescribed intravenous isotonic fluids and implement fall precautions (correct answer)

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key issue is hypernatremia and hypovolemia, shown by sodium 152 mEq/L, orthostatic hypotension, and tachycardia from prolonged vomiting. Starting prescribed intravenous isotonic fluids and implementing fall precautions is the best choice because it addresses dehydration and safety risks urgently. Administering antiemetic is lower priority; obtaining diet recall delays action; delegating ambulation is unsafe. The clinical decision-making principle applied is prioritizing volume replacement and fall prevention. This involves assessing postural vitals to confirm hypovolemia first. A transferable strategy is to initiate IV fluids and safety measures in clients with fluid losses and orthostasis.

Question 10

1. Lower the head of the bed to improve venous return and increase urine output
2. Elevate the head of the bed, maintain oxygen as ordered, and notify the RN of suspected fluid overload (correct answer)
3. Encourage oral fluids to thin respiratory secretions
4. Obtain a complete dietary history to determine sodium intake

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key issue is fluid overload, shown by jugular venous distention, crackles, tachypnea, and low oxygen saturation post-surgery. Elevating the head of the bed, maintaining oxygen as ordered, and notifying the RN of suspected fluid overload is the best choice because it improves breathing and escalates care. Lowering the bed would worsen symptoms; encouraging fluids is contraindicated; dietary history is not urgent. The clinical decision-making principle applied is prioritizing positioning and oxygenation in overload. This involves assessing neck veins and lungs. A transferable strategy is to elevate the head and apply oxygen while notifying in respiratory distress from fluids.

Question 11

1. Administer a potassium-binding medication without notifying the RN to avoid delaying treatment
2. Notify the RN immediately and prepare to implement ordered hyperkalemia protocols while maintaining cardiac monitoring (correct answer)
3. Teach the client to follow a low-potassium diet before discharge
4. Obtain a full pain assessment and reassess in 30 minutes

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hyperkalemia, with potassium 6.5 mEq/L, bradycardia, and chest fluttering in renal failure. Notifying the RN immediately and preparing to implement ordered hyperkalemia protocols while maintaining cardiac monitoring is the best choice because it prevents cardiac complications. Administering medication independently is outside scope; teaching diet is not urgent; pain assessment is irrelevant. The clinical decision-making principle applied is prioritizing escalation in critical hyperkalemia. This involves monitoring for symptoms like fluttering. A transferable strategy is to notify and prepare for interventions in hyperkalemia with cardiac changes.

Question 12

1. Notify the RN immediately and maintain continuous cardiac monitoring (correct answer)
2. Provide dietary teaching about limiting potassium intake
3. Encourage ambulation to reduce potassium level
4. Collect a stool sample to evaluate for gastrointestinal bleeding

Explanation: This question tests clinical judgment related to fluid and electrolyte management. The key electrolyte imbalance issue is hyperkalemia, with a potassium level of 6.3 mEq/L, irregular rhythm, and bradycardia in a client who missed dialysis. Notifying the RN immediately and maintaining continuous cardiac monitoring is the best choice because hyperkalemia can lead to cardiac arrest requiring urgent escalation. Providing dietary teaching is not immediate; encouraging ambulation is unsafe; collecting a stool sample is irrelevant. The clinical decision-making principle applied is prioritizing cardiac stability in critical hyperkalemia. This involves recognizing ECG changes and symptoms for prompt action. A transferable strategy is to ensure monitoring and notify the team for any missed dialysis in renal clients with elevated potassium.

Question 13

1. Heart rate 52/min with potassium 6.3 mEq/L (correct answer)
2. Sodium 140 mEq/L within expected range
3. Client reports feeling tired after poor sleep
4. Blood pressure 176/94 mmHg without headache

Explanation: This question tests clinical judgment related to recognizing cardiac manifestations of hyperkalemia in a dialysis patient. The key finding is the combination of bradycardia (52/min) with hyperkalemia (6.3 mEq/L), indicating cardiac conduction abnormalities that can progress to complete heart block or asystole. Heart rate 52/min with potassium 6.3 mEq/L (A) must be reported first because bradycardia in hyperkalemia indicates dangerous cardiac effects requiring immediate treatment. Normal sodium (B) is not concerning; fatigue from poor sleep (C) is non-urgent; hypertension without symptoms (D) is common in renal disease but less urgent than cardiac manifestations of hyperkalemia. The clinical decision-making principle is recognizing that cardiac rhythm changes in hyperkalemia represent a medical emergency requiring immediate intervention such as calcium gluconate, insulin/glucose, or emergency dialysis. When hyperkalemia presents with bradycardia or other ECG changes, always report immediately as cardiac arrest may be imminent.
