Correct Answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.

Correct Answer: D

Rationale: The correct answer is 'D. Breath sounds.' When a client receiving amlodipine develops edema, it is crucial to assess for potential heart failure, a side effect of the medication. Checking breath sounds helps in identifying any signs of pulmonary edema, a severe complication of heart failure. Choices A, B, and C are less relevant in this context. Bladder distention could be associated with urinary issues, serum albumin level with malnutrition or liver disease, and abdominal girth with gastrointestinal problems, none of which directly relate to the potential heart failure induced by amlodipine.

Correct Answer: C

Rationale: The correct action for the nurse to implement first is to stop the infusion. Stopping the infusion is crucial to prevent further potassium from being administered, which can exacerbate the client's hyperkalemia. Notifying the healthcare provider of the laboratory results (Choice A) can be done after taking immediate action to stop the infusion. Decreasing the rate of the IV infusion (Choice B) may not be sufficient to address the high potassium level quickly. Administering sodium polystyrene sulfonate (Kayexalate) (Choice D) is not the initial action for managing hyperkalemia; stopping the potassium infusion takes precedence.

Correct Answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.

Correct Answer: A

Rationale: The correct action for a client with type 1 diabetes mellitus experiencing hypoglycemia with a blood glucose level of 60 mg/dl is to administer 15 grams of carbohydrate. This will help raise the blood glucose levels quickly. Administering a glucagon injection (Choice B) is usually reserved for severe hypoglycemia where the client is unconscious or unable to swallow. Providing a snack with protein (Choice C) is not the first-line treatment for hypoglycemia as protein takes longer to raise blood glucose levels. Encouraging the client to rest (Choice D) may be beneficial after administering the carbohydrate, but the priority is to raise the blood glucose levels promptly.
