The healthcare provider prescribes an aerobic wound culture for a client with a pressure injury on the sacrum. To obtain the specimen accurately and reduce the risk of contaminated diagnostic results, in what order should the practical nurse perform the following actions? Arrange the steps from first to last.
- 1Remove the existing dressing and evaluate the status of the wound bed.
- 2Cleanse the wound thoroughly using sterile 0.9% sodium chloride.
- 3Rotate a sterile swab gently over an area of healthy-looking granulation tissue.
- 4Place the swab into the sterile culture transport tube without touching the edges.
- 5Apply the completed identification label to the specimen container at the bedside.
Cevap
The correct sequence is to first remove the dressing and evaluate the wound, then cleanse the wound with normal saline, next swab the viable granulation tissue, place the swab in the transport tube, and finally label the container at the bedside.
The correct sequence ensures the integrity of the diagnostic specimen, which is a critical risk reduction strategy. The wound must first be exposed and assessed. Next, it MUST be cleansed with sterile saline to remove surface contamination. Once clean, the swab is rotated on viable granulation tissue where the active pathogen resides. The swab is then safely secured in the transport tube to maintain sterility. Finally, labeling at the bedside prevents specimen mix-ups and ensures accurate diagnostics.

Anahtar Kavram
When obtaining a wound culture, the nurse must cleanse the wound with sterile saline before swabbing to ensure the specimen contains the actual pathogen from viable tissue rather than surface colonization or old exudate.
