Which intervention is most appropriate for a patient experiencing a severe manic episode?

Correct Answer: A

Rationale: The correct answer is A because a structured and low-stimulation environment can help reduce the intensity of the manic episode by providing predictability and minimizing triggers. This intervention promotes safety and stability for the patient. Option B may exacerbate the symptoms by overstimulating the patient. Option C may overwhelm the patient with information during a manic episode. Option D is risky as unsupervised time can lead to impulsive behaviors and potential harm.

Correct Answer: B

Rationale: The correct answer is B: Lithium. Lithium is often prescribed for patients with bipolar disorder because it helps stabilize mood by regulating neurotransmitter activity. It is a mood stabilizer that is effective in reducing manic episodes and preventing relapses. Sertraline (A) is an antidepressant and can potentially trigger manic episodes in patients with bipolar disorder. Haloperidol (C) is an antipsychotic used for treating psychotic symptoms but not specifically for stabilizing mood in bipolar disorder. Diazepam (D) is a benzodiazepine used for anxiety and not indicated for mood stabilization in bipolar disorder.

Correct Answer: C

Rationale: The correct answer is C: Nausea. Fluoxetine, an SSRI antidepressant, commonly causes gastrointestinal side effects such as nausea. This is due to its effect on serotonin levels in the gut. Weight gain (A) and increased appetite (B) are less common side effects of fluoxetine. Dry mouth (D) is more commonly associated with tricyclic antidepressants, not SSRIs. Monitoring for nausea is crucial to ensure patient compliance and well-being.

Correct Answer: B

Rationale: The correct answer is B: Teaching relaxation techniques. This intervention is effective in managing PTSD-related nightmares by helping the patient reduce anxiety and promote better sleep. Relaxation techniques, such as deep breathing and progressive muscle relaxation, can calm the nervous system and improve sleep quality. Encouraging the patient to journal before bedtime (Choice A) may help with processing emotions but may not directly address the nightmares. Avoiding discussing the nightmares directly (Choice C) can lead to avoidance behaviors and hinder the therapeutic process. Developing a safety plan (Choice D) is important for overall safety but does not specifically target the nightmares.

Correct Answer: B

Rationale: The correct answer is B: Electrolyte imbalances. In anorexia nervosa, electrolyte imbalances can lead to serious complications like cardiac arrhythmias and even sudden death. This is the most concerning finding as it directly impacts the patient's health and can be life-threatening. Bradycardia (choice A) is common in anorexia but usually reversible with treatment. Slight hypotension (choice C) may occur due to dehydration but can be managed. Lanugo (choice D) is a reversible side effect of malnutrition and not as concerning as electrolyte imbalances.
