A nurse is caring for a client who has a stage 3 pressure ulcer. The nurse should recognize that which of the following laboratory findings will affect wound healing?

Hemoglobin 16g/dL

INR 0.9

Serum albumin 3.2 g/dL

WBC count 8,000/mm

Answer and Explanation

The Correct Answer is C

Choice A rationale: Hemoglobin level reflects the oxygen-carrying capacity of the blood but is not a direct indicator of nutritional status.
Choice B rationale: International Normalized Ratio (INR) is a measure of blood clotting, and a normal value does not directly impact wound healing.
Choice C rationale: Serum albumin is a marker of nutritional status, and a low level (hypoalbuminemia) can adversely affect wound healing. Adequate protein intake is essential for collagen synthesis and overall tissue repair.
Choice D rationale: White blood cell count is an indicator of immune response and infection but does not directly affect wound healing in the absence of infection.

Correct Answer is A

Explanation

Choice A rationale: Phototherapy can sometimes cause sensitivity to light, and wearing dark glasses can help protect the eyes from excessive light exposure.
Choice B rationale: It is not typical to interrupt phototherapy due to redness and tenderness, as some skin reactions may occur during treatment but can be managed without interruption.
Choice C rationale: The schedule of phototherapy can vary, and the choice of days on and off may not necessarily be fixed in a three-day pattern.
Choice D rationale: The frequency and timing of phototherapy sessions depend on the specific treatment plan prescribed by the healthcare provider.

A. Swab the wound bed with a sterile cotton-tipped swab B. Cleanse the area around the wound with sterile saline. C. Don sterile gloves D. Place the collection tube in a specimen bag.

Correct Answer is C

Explanation

- A: Swabbing the wound bed is an essential step in obtaining a wound culture, but it is not the first action that should be taken. This step is performed after the wound has been cleansed to ensure that the sample is not contaminated with debris or bacteria from the surrounding skin.
- B: Cleansing the area around the wound with sterile saline is the correct first step. This action helps to remove any contaminants or debris from the wound surface, ensuring that the culture obtained is from the wound itself and not from the surrounding skin, which could lead to inaccurate results.
- C: Donning sterile gloves is a crucial step to maintain sterility during the procedure. However, it is not the first action because the nurse must first cleanse the wound area to prevent contamination of the culture specimen.
- D: Placing the collection tube in a specimen bag is done after obtaining the wound culture to transport the specimen to the laboratory. This is one of the final steps in the process, not the first.
