Difficulty: MediumPharmacological and Parenteral Therapies

A nurse is preparing to draw up a prescribed intravenous medication from a glass ampule. Arrange the following steps in the correct chronological order to ensure safe preparation.

  1. 1Tap the top of the ampule lightly to move all fluid into the lower chamber.
  2. 2Wrap a sterile gauze pad or an unopened alcohol swab around the ampule neck.
  3. 3Snap the ampule neck quickly and firmly away from the body.
  4. 4Attach a filter needle to a syringe and withdraw the medication.
  5. 5Remove the filter needle and attach an appropriate injection needle.

Answer

The correct chronological order for preparing medication from an ampule is: tap the ampule to clear the fluid from the neck, wrap the neck with a protective pad, snap the neck away from the body, withdraw the medication using a filter needle, and finally replace the filter needle with a standard injection needle.
Safe preparation of medication from a glass ampule follows a strict chronological sequence to prevent injury to the nurse and client. Tapping the ampule ensures the entire dose is in the lower chamber. Wrapping the neck provides a physical barrier, and snapping away from the body protects against flying glass. Using a filter needle is mandatory to prevent glass aspiration, and replacing it before administration ensures glass particles are not injected into the client.

Step-by-Step Solution

1
Tap the top of the ampule lightly.
The medication in the top of the ampule moves into the bottom chamber.
This ensures the full dose of the medication is available and prevents spilling when the ampule is opened.
2
Wrap a sterile gauze pad or unopened alcohol swab around the ampule neck.
A physical barrier is created around the scored glass.
This protects the nurse's fingers from cuts when the glass breaks.
3
Snap the ampule neck quickly and firmly away from the body.
The ampule is opened safely.
Directing the breaking force away from the body prevents glass shards from flying toward the nurse's face or eyes.
4
Attach a filter needle to a syringe and withdraw the medication.
The medication is drawn into the syringe without glass shards.
The filter needle catches any microscopic glass particles that may have fallen into the liquid when the ampule was snapped.
5
Remove the filter needle and attach an appropriate injection needle.
The syringe is safely prepared for administration to the client.
Filter needles are for drawing up only; using them for administration could inject trapped glass particles into the client.

Key Concept

Safe medication preparation from a glass ampule requires protecting the nurse from glass cuts and protecting the client from glass shards by using a filter needle.
