1. A client with diabetes is taking insulin lispro (Humalog) injections. The nurse should advise the client to eat:

Correct answer: A

Rationale: The correct answer is to eat within 10 to 15 minutes after the injection. Insulin lispro, also known as Humalog, is a rapid-acting insulin that starts working very quickly. Eating shortly after the injection helps match the food intake with the insulin action, reducing the risk of hypoglycemia. Choice B is incorrect because waiting 1 hour after the injection may lead to a mismatch between insulin activity and food intake. Choice C is incorrect as timing meals with lispro injections is essential to optimize glycemic control. Choice D is incorrect as eating 2 hours before the injection is not in alignment with the rapid action of insulin lispro and may lead to fluctuations in blood sugar levels.

2. The nurse is caring for a client who is scheduled for hemodialysis. Which of the following laboratory values should the nurse monitor closely before, during, and after the procedure?

Correct answer: D

Rationale: The correct answer is D: Serum potassium level. Before, during, and after hemodialysis, monitoring the serum potassium level is crucial to prevent hyperkalemia, a potentially life-threatening complication. Hemodialysis is done to remove waste products and excess electrolytes like potassium from the blood. Monitoring other laboratory values like hemoglobin, BUN, and creatinine is important in assessing kidney function and anemia, but serum potassium level requires close monitoring during hemodialysis due to the risk of rapid shifts that can lead to cardiac arrhythmias.

3. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

4. A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding should prompt immediate action by the nurse?

Correct answer: A

Rationale: The correct answer is A: Blood pressure of 76/58 mm Hg. In a client undergoing continuous venovenous hemofiltration (CVVH), hypotension can be a significant concern if replacement fluid does not adequately maintain blood pressure. The nurse should take immediate action to address hypotension to prevent further complications. The sodium level of 138 mEq/L is within normal range, and a potassium level of 5.5 mEq/L, while slightly elevated, may be expected in a patient with acute kidney injury. A pulse rate of 90 beats/min falls within the normal range and does not typically require immediate intervention in this context.

5. The nurse observes an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation following a transurethral resection of the prostate (TURP). What is the best initial nursing action?

Correct answer: C

Rationale: The best initial nursing action when observing an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation post-TURP is to increase the flow of the bladder irrigation. This action helps prevent blood clots from obstructing the catheter, ensuring effective drainage and promoting client comfort. Providing additional oral fluid intake (Choice A) is important for overall hydration but may not directly address the issue of blood clots in the drainage tubing. Measuring the client's intake and output (Choice B) is a routine nursing assessment that may not directly address the immediate concern of blood clots obstructing the catheter. Administering a PRN dose of an antispasmodic agent (Choice D) is not the best initial action as it does not directly address the issue of blood clots in the drainage tubing.
