Correct Answer is A
Explanation
A. WBC count 3,300/mm³.
Clozapine, an atypical antipsychotic medication, is associated with a risk of agranulocytosis, which is a severe reduction in white blood cell (WBC) count. A WBC count of 3,300/mm³ is significantly below the normal range, and it indicates a contraindication to the use of clozapine.
B. Asthma:
Asthma is not a contraindication to clozapine. However, it is important to monitor respiratory function as antipsychotic medications can have side effects related to respiratory function.
C. Hypertension:
Hypertension alone is not a contraindication to clozapine. Clozapine can, however, be associated with some cardiovascular side effects, so blood pressure should be monitored regularly.
D. Fasting blood glucose 120 mg/dL:
An elevated fasting blood glucose level is not a contraindication to clozapine. However, it is important to monitor metabolic parameters as antipsychotic medications, including clozapine, can be associated with metabolic side effects.
Correct Answer is B
Explanation
A. Incorrect. Falling asleep in the chair and refusing to eat lunch is not indicative of tardive dyskinesia (TD). TD is characterized by involuntary movements, not by changes in sleep patterns or appetite.
B. Correct. Grimacing and lip smacking are characteristic movements associated with tardive dyskinesia. TD is a side effect of long-term use of typical antipsychotic medications, and it involves involuntary, repetitive movements, often involving the face and mouth.
C. Incorrect. Excessive salivation and drooling are not specific to tardive dyskinesia. These symptoms may occur due to various reasons, and TD is primarily associated with abnormal, involuntary movements.
D. Incorrect. Experiencing muscle rigidity and tremors is more characteristic of other side effects or conditions, such as extrapyramidal symptoms, but it is not specific to tardive dyskinesia. TD typically involves repetitive, involuntary movements rather than tremors.
