Correct Answer: B

Rationale: A sudden increase in energy and talkativeness in a client with severe depression who has been on antidepressants for a short period may indicate an increased risk of suicide due to the potential shift from profound sadness to motivation to act. The first action the RN should take is to monitor the client closely for signs of suicidal behavior. Encouraging participation in group activities or praising the client for the apparent improvement may overlook the potential risk of suicidal behavior. While discussing the client's progress with the healthcare provider is important, the immediate concern is to ensure the client's safety by closely monitoring for any signs of suicidal ideation or behavior.

Correct Answer: A

Rationale: Dry mouth is a common side effect of MAO inhibitors like phenelzine due to their anticholinergic effects. Choices B, C, and D are incorrect as indigestion, diarrhea, and pink urine are not commonly associated side effects of phenelzine.

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: A

Rationale: The correct answer is A: Decreased thyroid stimulating hormone level. Hyperthyroidism causes an increased level of serum thyroid hormones (T3 and T4), which inhibit the release of TSH. In this case, a decreased TSH level can indicate hyperthyroidism, which can present with manic behavior. Elevated liver function profile (B) is not directly related to the manic phase of bipolar disorder. Increased white blood cell count (C) typically indicates an infection or inflammation, not directly related to the manic phase. Decreased hematocrit and hemoglobin levels (D) may suggest anemia but are not as crucial in the context of a manic phase of bipolar disorder.

Correct Answer: A

Rationale: The correct response is to choose A: 'Let's talk about your feelings of being monitored.' This response shows empathy and encourages the client to express his feelings. Engaging the client in a discussion about his feelings can help address underlying fears without directly challenging the delusion. Choice B is incorrect because directly denying the delusion may lead to increased distrust or agitation in the client. Choice C may come across as confrontational, which can exacerbate the client's paranoia. Choice D offers a false sense of assurance and does not address the client's concerns effectively.
