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: 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: An elevated BUN level indicates possible nephrotoxicity, which is a side effect of gentamicin and should be reported. Elevated serum creatinine and WBC count are not specifically related to gentamicin therapy. Normal serum glucose levels are also within the expected range.

Correct Answer: A

Rationale: The correct intervention for a client with obsessive-compulsive disorder is to allow the client enough time to perform rituals. This helps manage anxiety and stress in individuals with OCD. Allowing time for rituals can provide a sense of control and reduce distress. Choice B, giving the client autonomy in scheduling activities, may not address the core symptoms of OCD related to rituals and compulsions. Choice C, discouraging the client from exploring irrational fears, goes against the principles of exposure therapy, which is a common treatment for OCD. Choice D, providing negative reinforcement for ritualistic behaviors, is not recommended as it can reinforce the behavior rather than help the client manage it.

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.
