Correct Answer is D

Explanation

Choice A rationale:

A BUN of 22 mg/dL is slightly elevated but not a contraindication for clozapine.

Choice B rationale:

A serum potassium of 3.3 mEq/L is slightly low but not a contraindication for clozapine.

Choice C rationale:

A hematocrit of 55% is high but not a contraindication for clozapine.

Choice D rationale:

A WBC of 2,900 cells/mm² is low and can indicate agranulocytosis, a potentially life-threatening condition. Clozapine should be discontinued.

A. The importance of medication adherence after the resolution of acute psychosis when taking an antipsychotic. B. The importance of limiting fluid intake when taking an antipsychotic. C. The importance of routine red blood cell count laboratory work when taking an antipsychotic. D. The importance of avoiding foods that contain tyramine when taking an antipsychotic.

Correct Answer is A

Explanation

Choice A rationale:

Adherence to medication, especially after the resolution of acute psychosis, is crucial when taking an antipsychotic like clozapine. This is because discontinuation can lead to a relapse of symptoms.

Choice B rationale:

There’s no specific need to limit fluid intake when taking an antipsychotic.

Choice C rationale:

While routine blood cell count laboratory work is important, it’s not specific to red blood cells but rather to monitor for agranulocytosis, a potential side effect of clozapine.

Choice D rationale:

Avoiding foods that contain tyramine is typically associated with monoamine oxidase inhibitors, not antipsychotics like clozapine.
