Answer to Question 1

a

Answer to Question 2

C
The nurse should withhold the drug and notify the prescriber, because a trough level of 15 mcg/mL is high and may lead to aplastic anemia. The normal trough level is 5 to 10 mcg/mL.
The drug should not be administered as scheduled.
Nothing indicates that the measurement should be repeated.
An increase in the dose definitely would not be indicated, because the trough level is already high.
