Correct Answer: B

Rationale: The correct answer is 2 tablets. Each tablet of aspirin is 325mg. To achieve the required dose of 650mg, the nurse should administer 2 tablets. Choice A (1 tablet) is incorrect because it would only provide 325mg, which is half the required dose. Choices C (3 tablets) and D (4 tablets) are incorrect as they would exceed the required dose.

Correct Answer: D

Rationale: The correct answer is D because metformin should be held before a contrast CT scan to prevent the risk of kidney damage. Choices A, B, and C are all correct statements regarding the preparation and experience of a CT scan with contrast. It is important to fast before the procedure, keep the head still during the scan, and expect a warm sensation when the dye is injected.

Correct Answer: A

Rationale: The correct answer is A. Pursed-lip breathing is a nursing consideration for patients with COPD as it helps improve oxygenation and reduces air trapping. While administering bronchodilators and corticosteroids (choice B) is part of the treatment plan, it is typically done by healthcare providers. Monitoring oxygen saturation and arterial blood gases (ABGs) (choice C) is important but not a direct nursing consideration. Teaching the patient how to use an inhaler (choice D) is relevant but not specific to COPD care.

Correct Answer: B

Rationale: The correct recommendation to prevent hypoglycemic episodes in a client with diabetes who reports frequent episodes is to monitor blood glucose levels frequently. By monitoring blood glucose levels, the nurse can make necessary adjustments to insulin dosage and diet to maintain blood sugar levels within the target range. Increasing protein intake (Choice A) is not directly related to preventing hypoglycemia; it is more important to focus on balancing carbohydrates and insulin. Increasing the dose of insulin (Choice C) without proper monitoring can lead to further hypoglycemic episodes. Similarly, reducing carbohydrate intake (Choice D) should be done cautiously as carbohydrates are a main source of energy and sudden reduction can cause hypoglycemia in diabetic patients.

Correct Answer: B

Rationale: The most appropriate intervention for a client experiencing acute alcohol withdrawal is to administer diazepam. Diazepam is a benzodiazepine commonly used to prevent seizures and manage the symptoms of alcohol withdrawal. Encouraging physical activity may not be safe during acute withdrawal as the client may be at risk for seizures and other complications. Monitoring for signs of dehydration is important but not the most immediate intervention needed in acute alcohol withdrawal. While encouraging the client to verbalize their feelings is beneficial for therapeutic communication, it is not the priority intervention when managing acute alcohol withdrawal.
