Correct Answer: C

Rationale: The correct intervention for a client with PTSD experiencing flashbacks is to help them stay grounded in the present moment. This technique can reduce the intensity of flashbacks and provide a sense of safety. Encouraging the client to talk about the trauma (Choice A) may exacerbate the symptoms and should be done cautiously under professional guidance. Advising the client to avoid triggers (Choice B) is important, but solely relying on avoidance may not address the underlying issues. Referring the client to group therapy (Choice D) can be beneficial, but in the immediate context of managing flashbacks, grounding techniques are more appropriate.

Correct Answer: B

Rationale: The correct answer is B: 'Keep your dietary salt intake consistent.' Consistent salt intake is crucial when taking lithium carbonate to avoid lithium toxicity or ineffectiveness due to its renal excretion mechanism. Option A is incorrect because it focuses on the time to achieve therapeutic effects, which is important but not as critical as maintaining consistent salt intake. Option C is incorrect as it mentions avoiding aged cheese and chicken liver, which is more relevant for individuals taking MAOIs. Option D is incorrect as it suggests eating high-fiber foods, which is not directly related to lithium carbonate therapy.

Correct Answer: A

Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.

Correct Answer: B

Rationale: Assisting the client in exploring feelings of shame, anger, and guilt (B) is the most appropriate intervention for acute depression as it helps address core emotions that may be contributing to the condition. Focusing on these emotions can aid the client in processing and coping with their feelings. Ensuring that the client's day is filled with group activities (A) might overwhelm the client, as they may not be ready for social interactions during this sensitive time. Allowing the client to initiate and determine activities of daily living (C) is more suitable for chronic cases where the client needs to regain autonomy. Encouraging the client to explore the rationale for his depression (D) is less effective in acute cases, as the focus should be on immediate emotional support and understanding rather than cognitive analysis.

Correct Answer: B

Rationale: In the manic phase of bipolar disorder, clients often exhibit increased activity and may burn a lot of energy. Offering a high-calorie snack and a drink is the best intervention as it helps maintain their nutritional needs while allowing them to continue their activity. Encouraging the client to join a group activity (Choice A) may further stimulate their behavior. Directing the client to a quieter area (Choice C) might not address their energy expenditure. Instructing the client to sit down and relax (Choice D) may not be effective during the manic phase.
