Correct Answer: C

Rationale: In this situation, speaking assertively is the most appropriate action for the nurse to take. Confronting the client may escalate the situation further. Expressing sympathy, although important in other contexts, may not be effective in managing aggressive behavior. Standing within close proximity to an aggressive client can compromise the nurse's safety. Therefore, speaking assertively helps to set clear boundaries and manage the situation while ensuring safety in a seclusion room.

Correct Answer: B

Rationale: The correct answer is B. Clients taking furosemide, a potassium-wasting diuretic, should increase their intake of potassium-rich foods to prevent hypokalemia. Option A is incorrect because weight monitoring is crucial for furosemide due to fluid loss. Option C is incorrect as furosemide is usually taken in the morning to prevent nighttime diuresis. Option D is incorrect because furosemide is best taken on an empty stomach for better absorption.

Correct Answer: B

Rationale: Fresh vegetables are an excellent choice for clients on a low-sodium diet as they are naturally low in sodium. Pickles, canned soup, and smoked salmon are high in sodium and should be avoided by clients following a low-sodium diet. Pickles are pickled in a brine solution high in sodium, canned soup usually contains added salt for preservation, and smoked salmon is a processed food that typically has a high sodium content.

Correct Answer: B

Rationale: The correct answer is B: Amylase. Amylase is typically elevated in clients with acute pancreatitis due to inflammation of the pancreas. Elevated serum creatinine levels are more indicative of kidney dysfunction rather than pancreatitis. Hemoglobin levels are not directly related to pancreatitis. While blood glucose levels can be affected by pancreatitis, they are not typically the primary laboratory result expected to be elevated in this condition.

Correct Answer: D

Rationale: The correct statement the nurse should include is to take levothyroxine with a full glass of water before breakfast. This helps improve absorption and prevents gastrointestinal side effects. Choice A is incorrect because levothyroxine should be taken on an empty stomach. Choice B is incorrect as insomnia is not a common side effect of levothyroxine. Choice C is also incorrect as levothyroxine does not need to be refrigerated.
