Final answer:
The first action a nurse should perform when measuring a stage IV pressure ulcer is to perform hand hygiene to prevent infection.
Step-by-step explanation:
When measuring the size, depth, and wound tunneling of a client's stage IV pressure ulcer, the first action the nurse should perform is:
A) Perform hand hygiene.
Hand hygiene is the foundational step in any wound assessment procedure to prevent the introduction of microorganisms and reduce the risk of infection. Before examining or managing any wound, the nurse should thoroughly perform hand hygiene by washing hands with soap and water or using an alcohol-based hand sanitizer. This helps maintain aseptic technique and prevents the potential transmission of pathogens to the wound, ensuring patient safety and minimizing the risk of wound contamination.
After performing hand hygiene, the nurse can proceed with the wound assessment, which includes measuring the width, depth, and any tunneling of the stage IV pressure ulcer using appropriate techniques and tools. Proper wound measurement provides crucial information for monitoring healing progress and guiding the development of an effective care plan tailored to the individual's needs.
