Correct Answer: D

Rationale: Facial weakness is a common finding in clients with Guillain-Barr© syndrome due to muscle weakness. While increased urine output is not typically associated with Guillain-Barr© syndrome, hyperactive reflexes are more indicative of conditions like hyperthyroidism or spinal cord injury. Hypoactive bowel sounds are not a classic finding in Guillain-Barr© syndrome, making it an incorrect choice.

Correct Answer: C

Rationale: In caring for a client with schizophrenia experiencing delusions, it is essential to focus on the client's feelings rather than directly addressing or challenging the delusions. By focusing on the client's emotions, the nurse can build trust and rapport without reinforcing the delusions. Choice A is incorrect because directly telling the client that their delusions are not real may lead to confrontation or mistrust. Choice B is incorrect as encouraging exploration of the delusions may further validate them. Choice D is incorrect because challenging the client's delusions can escalate the situation and damage the therapeutic relationship.

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.

Correct Answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

Correct Answer: B

Rationale: In cases of benzodiazepine overdose, such as diazepam ingestion, flumazenil is the antidote. Therefore, the priority action for the nurse is to administer flumazenil to the client. Monitoring the IV site for thrombophlebitis (Choice A) is important but not the immediate priority. Evaluating the client for further suicidal behavior (Choice C) is important but not the next immediate action. Initiating seizure precautions (Choice D) is not the priority as the client's airway has already been secured.
