A 65-year-old client admitted with heart failure reports acute, severe nausea. The client's current vital signs include a blood pressure of 118/74 mmHg and a heart rate of 82 bpm. The healthcare provider prescribes 4 mg of ondansetron to be administered via intravenous (IV) push through an existing intermittent peripheral IV catheter (saline lock). Arrange the following steps in the correct chronological order for safely administering this parenteral medication.
- 1Clean the injection port of the intermittent IV catheter with an antimicrobial swab.
- 2Attach a syringe containing normal saline, aspirate for a blood return, and flush the line.
- 3Clean the injection port again with a new antimicrobial swab and attach the medication syringe.
- 4Administer the prescribed ondansetron slowly over the recommended amount of time.
- 5Clean the injection port and flush the catheter with normal saline at the same rate the medication was administered.
Cevap
The correct sequence for administering an IV push medication via a saline lock is to clean the port, assess patency with a saline flush, clean the port again, administer the medication, and perform a final saline flush at the medication's administration rate.
The standard sequence for administering medication via an intermittent IV lock utilizes the SAS method (Saline, Administer, Saline) while prioritizing infection control and patient safety. The nurse must scrub the hub before every connection. First, patency is verified with a saline flush. Next, the medication is administered at the appropriate rate. Finally, a post-administration flush clears the line, which must be given at the same rate as the medication to prevent a rapid bolus of the residual drug.
