Nursing Elites

1. An older client is admitted to the intensive care unit unconscious after several days of vomiting and diarrhea. The nurse inserts a urinary catheter and observes dark amber urine output. Which intervention should the nurse implement first?

• A. Begin dopamine infusion at 2 mcg/kg/minute.
• B. Begin potassium chloride 10 mEq over 1 hour.
• C. Give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes.
• D. Administer promethazine 25 mg IV push.

Correct answer: C

Rationale: In this scenario, the priority intervention is to give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes. The client's dark amber urine output indicates dehydration and hypovolemia, requiring rapid fluid resuscitation. Dopamine infusion, potassium chloride, and promethazine are not the initial interventions needed for a client with hypovolemic symptoms.

2. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

3. A client with diabetes insipidus is admitted due to a pituitary tumor. What complication should the nurse monitor closely?

• A. Monitor for elevated blood pressure.
• B. Monitor for ketonuria.
• C. Monitor for peripheral edema.
• D. Monitor for hypokalemia.

Correct answer: D

Rationale: The correct answer is to monitor for hypokalemia. In diabetes insipidus, excessive urination can lead to electrolyte imbalances, particularly low potassium levels (hypokalemia). The loss of potassium through increased urination can result in muscle weakness, cardiac dysrhythmias, and other serious complications. Elevated blood pressure (Choice A) is not a typical complication of diabetes insipidus due to pituitary tumors. Ketonuria (Choice B) is more commonly associated with diabetes mellitus due to inadequate insulin levels. Peripheral edema (Choice C) is not a direct complication of diabetes insipidus.

4. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

5. A client with deep vein thrombosis (DVT) is prescribed anticoagulants. What should the nurse monitor closely?

• A. Monitor for signs of bleeding, such as bruising.
• B. Monitor the client’s vital signs every hour.
• C. Monitor for pain in the affected limb.
• D. Assess for signs of pulmonary embolism, such as sudden shortness of breath.

Correct answer: D

Rationale: In clients with DVT, assessing for pulmonary embolism is crucial as a clot in the lungs can be life-threatening. Sudden shortness of breath or chest pain are key signs of a pulmonary embolism. While monitoring for signs of bleeding is important due to anticoagulant therapy, the immediate concern is detecting a potential pulmonary embolism. Monitoring vital signs and pain in the affected limb are relevant aspects of care but are not as urgent as assessing for pulmonary embolism in this scenario.
