A phlebotomist must collect TDM samples on two different patients, one for phenobarbital and the other for gentamicin. The collection times for both are the same. What should the phlebotomist do?
A. Obtain the phenobarbital first because it stays in the blood the shortest amount of time.
B. Collect the gentamicin first because it has a shorter half-life than the phenobarbital.
C. Ask a nurse to collect one of them because both must be drawn exactly when requested.
D. Reschedule the gentamicin since it can be drawn anytime before the trough occurs.
