A client is prescribed clozapine. The nurse instructs the client on the need for weekly laboratory testing for which of the following?
A) Serum lithium
B) WBC count
C) Blood glucose
D) pH level
Ans: B
Feedback:
Use of the drug clozapine has been associated with severe agranulocytosis (i.e., decreased white blood cells), so weekly WBC count tests are scheduled. Serum lithium tests are taken for clients who have been administered lithium, not clozapine. There is no need to check blood glucose or pH level.
