A client is prescribed digoxin and has a potassium level of 3.0 mEq/L. Which of the following actions should the nurse take?

Correct Answer: A

Rationale: A potassium level of 3.0 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity. In this case, the nurse should administer the digoxin without any modifications. Lowering the dose (Choice B) may not be necessary if the potassium level is not critically low. Monitoring serum potassium levels (Choice C) is important but should not delay the administration of digoxin. Discontinuing the medication (Choice D) is not the initial action to take unless the potassium levels become severely low and life-threatening.

Correct Answer: B

Rationale: The correct first action the nurse should take when preparing to administer a blood transfusion is to verify the blood type and crossmatch. This step is crucial to ensure compatibility and prevent transfusion reactions. Obtaining the client's consent is important but should follow the verification process. Taking baseline vital signs is necessary before starting the transfusion, but confirming compatibility takes precedence. Priming the IV with normal saline is a step done before starting the transfusion, after ensuring blood compatibility.

Correct Answer: D

Rationale: When a client is receiving corticosteroids, the nurse should monitor both blood glucose levels and blood pressure. Corticosteroids can elevate blood glucose levels, leading to hyperglycemia, and may cause hypertension. Monitoring these parameters is essential to detect and address any potential adverse effects promptly. While monitoring serum potassium levels is important in some situations, it is not a primary concern when caring for a client receiving corticosteroids. Therefore, choices A and B are the most appropriate options for monitoring in this scenario, making option D the correct answer.

Correct Answer: B

Rationale: The correct answer is B: 'Take it at the same time every day.' It is important to take levothyroxine consistently at the same time each day to maintain stable thyroid hormone levels. Choice A is incorrect as levothyroxine should be taken on an empty stomach for better absorption. Choice C is incorrect because stopping levothyroxine suddenly can lead to adverse effects due to sudden changes in hormone levels. Choice D is also incorrect as hyperglycemia is not a common side effect associated with levothyroxine.

Correct Answer: D

Rationale: When caring for a client receiving total parenteral nutrition (TPN), monitoring serum glucose levels is essential due to the impact TPN can have on glucose metabolism. Additionally, electrolytes like potassium should be monitored as they can be affected by TPN administration. Blood pressure monitoring is not directly related to TPN administration, making choices A and B the correct options to monitor in this scenario.
