Correct Answer: C

Rationale: The nurse's top priority upon admission is to determine if the client has been taking St. John's Wort, an herbal preparation often used for depression. St. John's Wort can interact adversely with medications used to treat HIV infection, potentially explaining the rise in the viral load (C). Asking about attending support groups (A) or recent changes in mood (D) may provide valuable information about the client's depression but is not as critical as determining St. John's Wort use. Holding antidepressant medications (B) without assessing for potential interactions can be harmful to the client.

Correct Answer: B

Rationale: The most important nursing intervention during the first 48 hours for a client with anorexia nervosa is monitoring vital signs and electrolytes (B) to assess for life-threatening complications. This helps in early detection of any physiological imbalances that could lead to serious consequences. Providing high-calorie, high-protein meals (A) is important for nutritional rehabilitation but comes after ensuring the client's physical stability. Encouraging the client to talk about feelings (C) and observing for signs of purging (D) are relevant aspects of care but are not as critical as monitoring vital signs and electrolytes in the initial phase of treatment.

Correct Answer: B

Rationale: The correct answer is B: Suicidal ideation. When dealing with a client diagnosed with major depression, assessing for suicidal ideation is of utmost importance. Individuals with major depression have an increased risk of suicide; hence, evaluating their risk for self-harm is crucial. Mood and affect, while important, come secondary to ensuring the safety of the client. Nutritional status and fluid and electrolyte balance are essential components of care but are not the priority when dealing with a client with major depression.

Correct Answer: A

Rationale: The correct answer is A: Information regarding shelters. Providing information about shelters is crucial in cases of family violence as it ensures the client has a safe place to go after discharge, prioritizing their immediate safety. Option B, instructions regarding calling the police, may be necessary but ensuring a safe place to stay is more immediate. Option C, instructions regarding self-defense classes, may not be appropriate as the priority is to ensure the client's safety rather than teaching self-defense. Option D, explaining the importance of leaving the violent situation, is relevant but providing information on immediate shelter options is the priority.
