A nurse is screening a group of clients for potential mental health conditions. Which of the following questions should the nurse ask to determine a client's risk for self-harm?

The correct answer is A: "Have you ever felt you should decrease your consumption of alcohol?" This question assesses the client's potential risk for self-harm by addressing the issue of alcohol consumption, which is a common risk factor for self-harm behaviors. Clients who feel the need to decrease their alcohol intake may be at higher risk for self-harm.
Choice B is incorrect as it focuses on liver damage and not on self-harm risk. Choice C is irrelevant to self-harm risk assessment. Choice D addresses family alcohol use but does not directly assess the individual's risk for self-harm. It is important to ask specific questions related to self-harm behaviors to accurately assess the client's risk.
