Final answer:
The CPCT must first confirm that the medication was administered at the scheduled time of 1100, then plan to draw the blood sample for the tobramycin level one hour later at 1200, adhering to the doctor's orders and hospital protocol.
Step-by-step explanation:
When a CPCT is caring for a patient who has an order for tobramycin (Tobrex) level to be drawn 1 hour after dosing, the first action the CPCT should take is to confirm the time when the medication was administered. If the medication is scheduled for 1100, the CPCT must ensure that it is given exactly at that time. Then, they must plan to draw the blood sample for the tobramycin level at 1200, which is one hour post medication administration. Tobramycin levels are measured to monitor drug concentration in the blood and to ensure therapeutic levels are achieved without reaching toxic levels.
It is crucial for the CPCT to closely follow the doctor's orders and hospital protocol for drawing blood and monitoring medication efficiency, as well as to document all actions taken. Good communication with nursing staff and proper documentation are vital components of patient care and medication administration.
