Correct Answer: A

Rationale: Defense mechanisms are employed by the ego, not the id or superego, in response to threats to biological or psychological integrity. They aim to relieve anxiety, not increase it. By redirecting focus, they help manage mild to moderate anxiety and are often self-deceptive in nature.

Correct Answer: D

Rationale: Electroconvulsive therapy (ECT) can have side effects such as short-term memory loss, headache, confusion, and nausea. Tardive dyskinesia is not a side effect of ECT; it is a movement disorder associated with long-term use of certain medications, particularly antipsychotics.

Correct Answer: D

Rationale: In caring for a client with bipolar disorder in a depressive episode, the nurse should implement interventions that promote mental well-being. Encouraging participation in activities, promoting adequate nutrition and hydration, and monitoring for suicidal ideation are all essential components of care. Discouraging verbalization of feelings is counterproductive as it hinders the therapeutic process and communication, which are crucial for the client's emotional expression and recovery.

Correct Answer: A

Rationale: Therapeutic communication techniques aim to establish a trusting and supportive relationship between the healthcare professional and the client. Using silence is a valid therapeutic technique that allows the client to reflect and express their thoughts. On the other hand, discouraging the client from washing their hands goes against good hygiene practices and is not therapeutic. Giving advice and providing reassurance can be non-therapeutic if not used appropriately, as they may undermine the client's autonomy and problem-solving abilities.

Correct Answer: D

Rationale: When assessing a client diagnosed with anorexia nervosa, healthcare professionals should expect findings such as amenorrhea, lanugo, hypotension, and bradycardia. Hyperkalemia is not typically associated with anorexia nervosa; instead, hypokalemia, which is low potassium levels, is more commonly seen in these individuals due to malnutrition and other factors.
