Question

Quizplus · Accepted Answer

The trough level for tobramycin, an aminoglycoside antibiotic, should be drawn just before the next dose is administered to ensure the lowest concentration in the bloodstream is measured. Since the dose is scheduled for 8:00 AM, the trough level should be drawn at 7:45 AM.
