Final answer:
The lab value indicating that a client on enteral tube feedings needs additional nutrients is a white blood cell count of 22,000/mm³, which suggests an elevated metabolic demand due to infection or inflammation.
Step-by-step explanation:
A nurse caring for an older client on enteral tube feedings needs to evaluate lab values to determine if the client requires additional nutrients. Among the available lab results, an indication that additional nutrients might be needed is:
- Capillary blood glucose of 120 mg/dL
- White blood cell count of 22,000/mm³
- Hemoglobin level of 12 g/dL
- Platelet count of 160,000/mm³
The correct answer is (b) White blood cell count of 22,000/mm³. A high white blood cell count often indicates an infection or inflammation, which can increase metabolic demands and nutrient requirements. The other options do not specifically indicate a need for additional nutrients. A capillary blood glucose level of 120 mg/dL is within a normal range for someone who may not be fasting, a hemoglobin level of 12 g/dL is within normal limits, and a platelet count of 160,000/mm³, while on the lower end of normal, does not directly indicate malnutrition or the need for additional nutrients.
