Final answer:
The most appropriate nursing action for a client with a pressure ulcer and slightly low prealbumin levels, but otherwise normal lab values, is to request a dietary consult to address potential nutritional needs to aid in wound healing.
Step-by-step explanation:
The student's question asks which action by the nurse is most appropriate after reviewing a client's laboratory values that indicate a pressure ulcer with specific blood counts. With the given laboratory values showing a normal white blood count of 8000/mm3, a slightly low prealbumin level of 15.2 mg/dL, normal albumin 4.2 mg/dL, and a normal lymphocyte count of 2000/mm3, the most appropriate action would be A. Request a dietary consult. This is because the slightly low prealbumin suggests possible malnutrition, which could impair wound healing. While the white blood cell count and lymphocytes are within normal ranges, indicating no systemic infection, nutrition is critical in promoting wound healing, and a registered dietitian can provide recommendations for nutritional therapy to support the healing of the pressure ulcer.
