A patient is prescribed 150 mg/day of Lithium, divided into two equal doses. How much Lithium should be given per dose?
150 mg.
75 mg.
50 mg.
100 mg.
The Correct Answer is B
Choice A reason: Giving 150 mg in one dose would mean the full daily dose is administered at once, not divided as ordered.
Choice B reason: The total daily dose is 150 mg. Dividing this into two equal doses means 150 ÷ 2 = 75 mg per dose.
Choice C reason: Fifty mg per dose would only total 100 mg per day, which is below the prescribed dose.
Choice D reason: One hundred mg per dose would total 200 mg daily, which exceeds the prescribed 150 mg/day.

Correct Answer is C
Explanation
Choice A reason: The Hamilton Depression Scale is used to assess severity of depression, not antipsychotic side effects.
Choice B reason: The Body Attitude Test is used in eating disorder assessments, unrelated to risperidone therapy.
Choice C reason: The Abnormal Involuntary Movement Scale (AIMS) evaluates for movement disorders like tardive dyskinesia, which are possible side effects of antipsychotics. Baseline assessment is essential before starting treatment.
Choice D reason: The Recovery Attitude and Treatment Evaluator measures patient attitudes about recovery and treatment, not medication side effects.
Correct Answer is D
Explanation
Choice A reason: Directly rejecting the belief is non-therapeutic and may increase defensiveness, damaging trust.
Choice B reason: Telling the client to stop worrying invalidates their feelings and dismisses the emotional impact of the delusion.
Choice C reason: Participating in the delusion by “looking for cameras” reinforces the false belief, which is not supportive of reality testing.
Choice D reason: Acknowledging the client’s fear while gently presenting reality and shifting toward problem-solving helps maintain trust and supports reality testing.
