What time should a nurse schedule the blood sample for trough levels of vancomycin?

The appropriate time to schedule the blood sample for trough levels of vancomycin is just before the medication is administered. Trough levels represent the lowest concentration of the drug in the bloodstream, which helps to ensure that the drug remains within the therapeutic range without causing toxicity.

By taking the blood sample just before administration, the nurse can accurately assess whether the drug level is low enough to allow for another dose of vancomycin. This timing is critical for maintaining effective and safe plasma concentrations, as trough levels are used to adjust dosages for optimal patient care. Scheduling the blood sample at this time helps healthcare providers make informed decisions regarding continued treatment with vancomycin.
