A registered nurse is preparing to administer an intravenous (IV) push medication through a client's accessed, but currently inactive, implanted venous port (Port-a-Cath). Based on standard facility protocol for a heparin-locked central venous device, arrange the following steps in the correct chronological order.
- 1Scrub the needleless connector with an antimicrobial swab, aspirate for a blood return, and flush with 0.9% sodium chloride.
- 2Scrub the needleless connector again, attach the medication syringe, and administer the intravenous (IV) push medication at the prescribed rate.
- 3Scrub the needleless connector, attach a new syringe of 0.9% sodium chloride, and flush the line using a pulsatile technique.
- 4Scrub the needleless connector, attach the heparin syringe, and instill the prescribed volume of heparin flush solution.
- 5Clamp the extension tubing while simultaneously maintaining positive pressure on the syringe plunger.
Cevap
The correct sequence follows the SASH protocol: Saline flush (with aspiration), Administer medication, Saline flush, Heparin flush, followed by clamping the tubing with positive pressure.
The SASH protocol is the standard of practice for administering medications through a heparin-locked central venous device. The sequence ensures that the line is patent before medication is given, prevents chemical incompatibilities by flushing before and after administration, and secures the line with anticoagulant and positive pressure clamping to prevent future occlusions. Rigorous infection control is maintained by scrubbing the hub before every syringe attachment.
