Final answer:
The phlebotomist should draw the blood for the Tobramycin level at 1200, which is one hour after the scheduled 1100 administration of the medication. This timing is essential for the accurate monitoring of drug concentration to avoid toxicity and ensure therapeutic effectiveness.
Step-by-step explanation:
Action for Tobramycin Level Blood Draw
The phlebotomist should schedule the blood draw for one hour after the administration of the Tobramycin dose. Since Tobramycin is supposed to be administered at 1100, the appropriate time to draw the blood for the Tobramycin level would be at 1200. It is crucial to follow physician orders precisely when drawing medication levels to ensure accurate measurement of the drug's concentration in the patient's bloodstream.
Tobramycin level monitoring is critical because it helps in adjusting the dose to avoid toxicity and ensure therapeutic effectiveness. The timing of the blood draw is particularly important with drugs like Tobramycin that have a narrow therapeutic index and require careful monitoring. Failing to draw the blood at the right time could result in incorrect dosage adjustments and potentially harmful consequences for the patient.
