Correct Answer: D

Rationale: Reporting insomnia or agitation to the provider is critical, as these are common side effects of bupropion, an antidepressant that stimulates norepinephrine and dopamine, and may require dose adjustment or alternative therapy.
Choice A is incorrect because bupropion is typically taken in the morning or twice daily, as it can cause insomnia if taken at bedtime.
Choice B is incorrect because moderate caffeine intake is generally safe, though excessive caffeine may exacerbate agitation.
Choice C is incorrect because bupropion is more likely to cause weight loss, not weight gain, unlike some other antidepressants.

Correct Answer: A

Rationale: Flashbacks of the traumatic event are a hallmark symptom of PTSD, where clients vividly re-experience the trauma, leading to significant distress.
Choice B is incorrect because euphoria is not associated with PTSD; clients typically experience anxiety, depression, or hypervigilance.
Choice C is incorrect because PTSD often causes insomnia or nightmares, not an increased need for sleep.
Choice D is incorrect because weight gain is not a primary feature; weight changes may occur secondary to depression or medication side effects.

Correct Answer: A

Rationale: Weight gain is a common adverse effect of risperidone, an atypical antipsychotic, due to its effects on metabolism and appetite, requiring monitoring to manage long-term health risks.
Choice B is incorrect because, while hypotension may occur, it is less frequent than weight gain and more associated with initial dosing.
Choice C is incorrect because bradycardia is not a typical side effect; tachycardia may occur with agitation or overdose.
Choice D is incorrect because hypoglycemia is not associated with risperidone; hyperglycemia may occur due to metabolic changes.

Correct Answer: C

Rationale: Exercise for 30 minutes most days of the week is recommended for clients with gestational diabetes mellitus, as it improves insulin sensitivity, helps control blood glucose levels, and supports overall health.
Choice A is wrong because while monitoring blood glucose is essential, the frequency (e.g., four times daily) depends on the provider's plan and the client's condition; the nurse should specify the prescribed schedule.
Choice B is wrong because limiting carbohydrates to 50% of daily calories is not a standard recommendation; carbohydrate intake should be individualized (typically 40-50% of calories) and balanced with protein and fats, as advised by a dietitian.
Choice D is wrong because oral hypoglycemic medications are not first-line for gestational diabetes; insulin is preferred if diet and exercise are insufficient, and oral medications like metformin may be considered in specific cases under provider guidance.

Correct Answer: A

Rationale: Lanugo (fine, soft hair) on the face and body is a common finding in anorexia nervosa due to the body's attempt to conserve heat in response to severe weight loss and malnutrition.
Choice B is incorrect because anorexia nervosa typically causes hypothermia due to low body fat and reduced metabolic rate, not hyperthermia.
Choice C is incorrect because bradycardia, not tachycardia, is common due to decreased metabolic demand and electrolyte imbalances.
Choice D is incorrect because hypotension, not hypertension, is typical due to dehydration and reduced cardiac output.
