Correct Answer: D

Rationale: The nurse should acknowledge the client's awareness of the irrationality of their behavior and the feeling of powerlessness to change it. By reflecting the client's feelings, the nurse validates them and opens a discussion on strategies to manage the behavior effectively. Empathy and understanding are key in supporting clients with OCD. Choice A is incorrect because it focuses more on changing the behavior rather than acknowledging the client's feelings. Choice B is incorrect as it does not directly address the client's sense of powerlessness. Choice C is incorrect as it doesn't validate the client's feelings of being unable to control the behaviors.

Correct Answer: B

Rationale: In anorexia nervosa, individuals often develop lanugo, fine soft hair, on the face and back. This is a physiological response to the body's attempt to conserve heat due to a lack of subcutaneous fat. It is a common physical finding in clients with anorexia nervosa and can be a sign of severe malnutrition. Choices A, C, and D are incorrect because weight gain and increased appetite, increased body temperature and tachycardia, and hyperactivity and distractibility are not typically associated with anorexia nervosa. In fact, weight loss, decreased appetite, hypothermia, and bradycardia are more commonly seen in individuals with anorexia nervosa.

Correct Answer: A

Rationale: The initial action the nurse should take is to encourage the client to talk about the traumatic event during the day. This approach can assist the client in processing the trauma in a controlled environment, potentially reducing the frequency and intensity of nightmares. It allows for emotional expression and may promote better sleep by addressing the underlying psychological distress associated with PTSD. Encouraging the client to talk about the event during the day promotes therapeutic processing of the trauma and emotional expression, which can lead to improved coping mechanisms and potentially decrease the distressing symptoms like nightmares. Encouraging the client to avoid caffeine and alcohol may be beneficial, but addressing the emotional aspects first is crucial. Administering a sedative should not be the first approach, as it does not address the root cause of the nightmares. Scheduling a follow-up appointment with the therapist is important but should follow addressing the immediate distressing symptoms and promoting coping strategies.

Correct Answer: C

Rationale: Interventions for a client with anorexia nervosa include monitoring daily caloric intake and weight, establishing a structured eating plan, providing liquid supplements as prescribed, and offering rewards for weight gain. However, encouraging the client to exercise is not appropriate as it may exacerbate the condition by increasing caloric expenditure and reinforcing unhealthy behaviors associated with the disorder. Exercise may further contribute to excessive weight loss and worsen the client's physical health in the context of anorexia nervosa.

Correct Answer: B

Rationale: The initial priority for the nurse is to ensure the safety of the client. Placing the client on one-to-one observation allows for constant monitoring and intervention if there are any signs of self-harm or a worsening condition. This immediate intervention is crucial to prevent further harm. Options A, C, and D involve therapeutic communication and interventions, which are important but should come after ensuring the client's safety.
