Correct Answer: A

Rationale: Encouraging the client to talk about the flashbacks is the most appropriate initial intervention for a client with PTSD experiencing flashbacks and nightmares. This intervention helps the client express their feelings, thoughts, and experiences related to the trauma they are going through. It can assist in processing the traumatic events and starting the healing process. Choice B, assisting the client in developing coping strategies, is important but should come after the client has started to verbalize and process their experiences. Choice C, discussing relaxation techniques, may be beneficial later in the treatment process but may not be as effective initially as addressing the traumatic experiences. Choice D, referring the client to a PTSD support group, is also valuable but may not be as immediate as encouraging the client to talk about their flashbacks to begin the therapeutic process.

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: B

Rationale: The most important instruction for a client prescribed lithium carbonate is not to change their salt intake. Alterations in sodium levels can impact lithium levels, leading to an increased risk of toxicity. Choice A is not crucial for lithium carbonate administration. While hydration is essential, maintaining a consistent salt intake is more critical than just increasing water intake (Choice C). Although caffeine can interact with lithium, it is not as important as maintaining a consistent salt intake (Choice D).

Correct Answer: D

Rationale: The correct action for the nurse to take in this situation is to administer the prescribed anticholinergic benztropine (Cogentin) for dystonia. Dystonia can be a side effect of antipsychotic medications like risperidone, leading to involuntary muscle contractions and abnormal postures. Benztropine is an anticholinergic medication commonly used to treat dystonia. Choices A, B, and C are incorrect because thioridazine is not the appropriate medication in this case, a hot pack would not address the underlying issue of dystonia, and occupational therapy is not the primary intervention for addressing acute dystonic reactions.

Correct Answer: B

Rationale: The correct answer is B: Projection. In this scenario, the client is projecting his own feelings of anger and selfishness onto his roommate. Projection is a defense mechanism where individuals attribute their own unacceptable thoughts, feelings, and motives to another person. Choices A, C, and D are incorrect. Denial is refusing to acknowledge an aspect of reality or experience. Rationalization is providing logical-sounding reasons to justify unacceptable behaviors or feelings. Splitting is seeing individuals as all good or all bad, with no middle ground.
