Nursing Elites

1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is B: Administer intravenous insulin and glucose. In the presence of hyperkalemia, the priority intervention is to shift potassium back into the cells to lower serum levels. Insulin, in combination with glucose, helps drive potassium intracellularly. Administering calcium gluconate (choice A) is used to stabilize myocardial cell membranes but does not address the underlying cause of hyperkalemia. Administering sodium bicarbonate (choice C) is not the initial treatment for hyperkalemia. Loop diuretics (choice D) may be used later to enhance potassium excretion but are not the primary intervention for acute hyperkalemia.

2. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

• A. Serum potassium of 4.0 mEq/L
• B. Blood glucose of 200 mg/dl
• C. Serum creatinine of 1.5 mg/dl
• D. Serum potassium of 3.2 mEq/L

Correct answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.

3. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum bicarbonate of 18 mEq/L
• C. Serum glucose of 350 mg/dl
• D. Serum sodium of 135 mEq/L

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.

4. After receiving lactulose, a client with hepatic encephalopathy has several loose stools. What action should the nurse implement?

• A. Send stool specimen to the lab
• B. Measure abdominal girth
• C. Encourage increased fiber in the diet
• D. Monitor mental status

Correct answer: D

Rationale: The correct action for the nurse to implement after a client with hepatic encephalopathy has loose stools following lactulose administration is to monitor the client's mental status. Lactulose is given to lower serum ammonia levels in hepatic encephalopathy, and loose stools can be an expected side effect of its use. Monitoring mental status is crucial because changes in mental status, such as confusion or altered level of consciousness, are key indicators of hepatic encephalopathy worsening. Sending a stool specimen to the lab would not be the priority in this situation as loose stools are a known effect of lactulose. Measuring abdominal girth is more relevant for conditions like ascites, not loose stools. Encouraging increased fiber in the diet may be beneficial for constipation but is not the immediate action needed when loose stools occur after lactulose administration.

5. A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme (ACE) inhibitor. Which instruction should the nurse include in the medication teaching plan?

• A. Increase intake of potassium-rich foods.
• B. Report increased bruising or bleeding.
• C. Stop medication if a cough develops.
• D. Limit intake of leafy green vegetables.

Correct answer: B

Rationale: The correct instruction for the nurse to include in the medication teaching plan is to 'Report increased bruising or bleeding.' ACE inhibitors can cause thrombocytopenia, which lowers platelet count and increases the risk of bruising and bleeding. Choice A is incorrect because while ACE inhibitors may cause potassium levels to increase, the instruction should not be to increase intake of potassium-rich foods without healthcare provider guidance. Choice C is incorrect because a cough is a common side effect of ACE inhibitors due to bradykinin accumulation, and stopping the medication abruptly is not recommended without consulting the healthcare provider. Choice D is incorrect because there is no need to limit intake of leafy green vegetables specifically with ACE inhibitors; however, consistent intake of vitamin K-rich foods is recommended to maintain a stable INR for clients taking anticoagulants.
