Final answer:
The peak level of an antibiotic administered by intravenous piggyback halfway between two doses of the medication is known as the trough level.
Step-by-step explanation:
The peak level of an antibiotic administered by intravenous piggyback halfway between two doses of the medication is known as the trough level.
When a drug is administered intravenously, it rapidly reaches its peak concentration in the bloodstream. Over time, the drug is eliminated from the body, and the concentration decreases. The trough level is the lowest concentration of the drug in the bloodstream, which occurs just before the next dose is administered.
Monitoring the trough level is important to ensure that the drug remains at a therapeutic level and that it is not toxic to the body.
