A nurse is assessing for cyanosis in a client who has dark skin. Which of the following sites should the nurse examine to identify cyanosis in this client?

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.

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.
