Correct Answer: D

Rationale: The correct answer is D. When a client is prescribed warfarin, they should be educated to report any unusual bleeding or bruising promptly. Choices A, B, and C are incorrect. Avoiding foods rich in vitamin K is not necessary when taking warfarin, as long as intake remains consistent. Warfarin does not need to be taken with meals, and aspirin should not be taken for pain relief due to its blood-thinning effects, which can increase the risk of bleeding when combined with warfarin.

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: B

Rationale: The correct action for the nurse to take when finding that the TPN solution is infusing too rapidly is to stop the TPN infusion. This is crucial to prevent fluid overload and ensure the client's safety. Sitting the client upright (Choice A) or turning the client on their left side (Choice C) are not appropriate responses to a rapidly infusing TPN solution and do not address the immediate issue of preventing complications from the rapid infusion. Adding insulin to the TPN infusion (Choice D) is not indicated unless specifically prescribed by the healthcare provider for the client's condition. Therefore, the priority action is to stop the TPN infusion to prevent potential harm.

Correct Answer: D

Rationale: The correct answer is assessing the gag reflex. This is the priority assessment following an EGD procedure to prevent aspiration. Checking the gag reflex helps ensure the client's airway protection. Assessing the level of consciousness is important, but ensuring the client can protect their airway takes precedence. Pain and nausea assessments are also essential but are secondary to maintaining airway patency.

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.
