Correct Answer: C

Rationale: The correct action in the medication reconciliation process is to compare prescriptions with the client's medications. This step ensures that there are no conflicting medications prescribed, reducing the risk of adverse drug interactions. Discontinuing current medications or writing new prescriptions without comparing them can lead to errors and potential harm. Asking the client to decide is not appropriate in this context as it is the nurse's responsibility to ensure medication safety based on professional judgment and knowledge.

Correct Answer: A

Rationale: A CT scan is the priority diagnostic test to identify and confirm the location and severity of a stroke.

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: B

Rationale: In this situation, the nurse should irrigate the catheter with 0.9% sodium chloride irrigation. This action helps clear the clots in the catheter and restore proper urine flow after a TURP. Administering an antispasmodic (Choice A) is not the appropriate action for clots in the catheter and decreased urinary output. Applying gentle manual pressure to the bladder (Choice C) or clamping the catheter tubing (Choice D) could potentially worsen the situation by causing bladder distention or preventing urine drainage.

Correct Answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.
