Correct Answer: A

Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.

Correct Answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.

Correct Answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with frequent rest periods is the best strategy to promote independence. This approach helps the client regain confidence and autonomy in performing self-care activities. Instructing the client to rest until fully recovered (Choice A) may lead to decreased muscle strength and independence. Assigning assistive personnel (Choice C) does not empower the client to actively participate in their care. Involving the client's family (Choice D) may provide support but does not directly encourage the client's independence.

Correct Answer: B

Rationale: Reducing sodium intake is crucial for managing hypertension as excess sodium can lead to increased blood pressure. High-fat foods (Choice A) are not recommended as they can contribute to heart issues. While dairy products (Choice C) should be consumed in moderation, they are not specifically targeted in hypertension management. High-protein foods (Choice D) are not the priority; rather, reducing sodium intake takes precedence due to its direct impact on blood pressure levels.

Correct Answer: C

Rationale: The correct action for the nurse to take is to pour warm water over the client's perineum. This intervention helps stimulate urination after catheter removal by providing warmth and promoting relaxation of the muscles. Assessing for bladder distention after 2 hours (Choice A) is not the initial intervention to facilitate voiding. Encouraging the client to try urinating in a sitting position (Choice B) may be uncomfortable if the client is struggling to void. Restricting the client's fluid intake (Choice D) is not appropriate as it can further exacerbate the issue by concentrating the urine.
