Correct Answer: B

Rationale: Administering flumazenil is the priority to reverse the effects of diazepam overdose. Flumazenil is a specific benzodiazepine receptor antagonist that can rapidly reverse the sedative effects of diazepam. Monitoring the IV site for thrombophlebitis is important but not the immediate priority in this situation. Evaluating the client for further suicidal behavior is important for comprehensive care but is not the most urgent action at this moment. Initiating seizure precautions may be necessary, but the priority is to counteract the sedative effects of diazepam with flumazenil.

Correct Answer: D

Rationale: The correct answer is D. Clients taking furosemide should avoid alcohol because it can lead to dehydration and potential interactions with the medication. Choices A and B are incorrect because furosemide is a diuretic that can actually lower potassium levels, so the client should not expect an increase in potassium levels or solely rely on bananas for potassium intake. Choice C is incorrect because a cough is not a common side effect of furosemide and should not be a reason to stop taking the medication.

Correct Answer: C

Rationale: The correct intervention for a client with severe preeclampsia is to monitor intake and output. This is crucial to assess kidney function, fluid balance, and detect any signs of deterioration. Administering magnesium sulfate is indicated for seizure prophylaxis in severe preeclampsia, but it is not the primary intervention related to care planning. Placing the client in the left lateral position is not a specific intervention for managing preeclampsia. Providing a low-sodium diet is not typically recommended for clients with severe preeclampsia as sodium restriction is not a primary treatment modality for this condition.

Correct Answer: C

Rationale: The correct action for the nurse to take when using an IV pump for a newly admitted client is to hold the IV pump cord while walking the client. This is important for ensuring the safe and secure management of the IV pump during client mobility. Option A is incorrect as grasping the IV pump cord when unplugging it can lead to electrical hazards. Option B is incorrect as ensuring the pump is plugged into an outlet with two prongs is important for electrical safety but not directly related to the nurse's action. Option D is also important but does not directly address the nurse's immediate action while using the IV pump with the client.

Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.
