A nurse is reviewing the laboratory results of a client who has a pressure ulcer. The nurse should identify an elevation in which of the following laboratory values as an indication that the client has developed an infection?
RBC count
WBC count
Potassium
BUN
The Correct Answer is B
A. An elevation in the red blood cell (RBC) count is not a specific indication of infection. It primarily reflects oxygen-carrying capacity.
B. An elevation in the white blood cell (WBC) count is an indication of infection. When the body is fighting an infection, the number of white blood cells increases as part of the immune response.
C. Potassium is an electrolyte and is not a specific marker for infection. Abnormal potassium levels may indicate a variety of conditions, but they do not directly indicate infection.
D. Blood urea nitrogen (BUN) is a marker of kidney function and is not a specific indicator of infection. Elevated BUN levels can be seen in various kidney and non-kidney-related conditions.

Correct Answer is ["B","C","D","E","F"]
Explanation
A. Potassium level is incorrect because it is within the normal range and does not affect wound healing directly.
B. Prealbumin level is correct because it is low, indicating malnutrition and poor protein intake, which are essential for tissue repair and immune function.
C. History of diabetes mellitus is correct because it causes impaired blood flow, increased risk of infection, and delayed inflammatory response, which all hinder wound healing.
D. History of hyperlipidemia is correct because it causes atherosclerosis and reduced blood supply to the affected area, which limits oxygen and nutrient delivery to the wound.
E. Wound infection is correct because it increases inflammation, tissue damage, and metabolic demands, which prolong the healing process and may lead to complications.
F. Decreased pedal perfusion is correct because it indicates poor circulation to the lower extremities, which impairs wound healing by reducing oxygen and nutrient delivery to
the wound.
G. Fasting blood glucose is incorrect because it is not a direct cause of delayed wound healing, but rather a reflection of the client's diabetes management. However, high blood glucose levels can impair wound healing by affecting blood flow, immune function, and collagen synthesis.
Correct Answer is ["A","B","E"]
Explanation
A. Providing oral care involves contact with mucous membranes and saliva, which may contain blood or other potentially infectious materials. Therefore, the nurse should wear gloves to protect themselves and the client from cross-contamination.
B. Emptying urine from an indwelling urine collection bag involves contact with urine, which may contain blood or other potentially infectious materials. Therefore, the nurse should wear gloves to protect themselves and the client from cross-contamination.
C. Placing oral medication tablets into a client's hand does not involve contact with blood or other potentially infectious materials. Therefore, the nurse does not need to wear
gloves for this task.
D. Delivering a food tray to a client who has AIDS does not involve contact with blood or other potentially infectious materials. Therefore, the nurse does not need to wear gloves for this task. However, the nurse should follow standard precautions and wash their hands before and after contact with any client.
E. Changing an ostomy pouch involves contact with feces, which may contain blood or other potentially infectious materials. Therefore, the nurse should wear gloves to protect themselves and the client from cross-contamination.
