Correct Answer: C

Rationale: Tachycardia is a potential adverse effect of levothyroxine, indicating overmedication. Dysuria (painful urination) is not typically associated with levothyroxine. Leg cramps are not a common adverse effect of levothyroxine. Blurred vision is not a typical adverse effect of levothyroxine; instead, it may be a sign of other eye-related conditions or medication side effects.

Correct Answer: A

Rationale: The best method for communicating a vision for the future is to involve others in creating the vision and connect daily work tasks to the vision. This approach fosters ownership and commitment among team members, as they feel part of the vision-building process and understand how their daily tasks contribute to achieving that vision. Choice B, encouraging staff nurses to openly discuss practice and possible improvements, is important for fostering communication but doesn't directly address creating and communicating a vision. Choice C, critically analyzing and discussing advances in practice with other nurses, focuses on professional development and knowledge sharing rather than specifically communicating a future vision. Choice D, actively listening to recommendations, is valuable for gathering input but may not be sufficient on its own for effectively communicating a future vision.

Correct Answer: A

Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.

Correct Answer: C

Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. This is essential to ensure that the client's blood glucose levels remain within the target range and to prevent complications such as hypo- or hyperglycemia. Choices A, B, and D are incorrect because giving a regular diet as ordered, holding insulin on the morning of surgery, or stopping insulin 48 hours before surgery can lead to uncontrolled blood glucose levels, posing risks to the client's safety during the surgical procedure.

Correct Answer: B

Rationale: The correct answer is B. Prednisone is a corticosteroid that can cause hyperglycemia by increasing glucose production in the liver. Atenolol (Choice A) is a beta-blocker that typically does not affect blood glucose levels significantly. Phenelzine (Choice C) is a monoamine oxidase inhibitor used for depression and does not directly impact blood glucose levels. Allopurinol (Choice D) is a xanthine oxidase inhibitor used to manage gout and does not contribute to hyperglycemia.
