The nurse reviews the female client's laboratory test results for a nutritional assessment. Which is the best indicator of a nutritional deficit in the client?
1. Hemoglobin 15 g/dL
2. Prealbumin 11 mg/dL
3. Cholesterol 180 mg/dL
4. Absolute lymphocytes 1750

2. The best indicator of a nutritional deficit is a low serum prealbumin level because prealbumin is a sensitive indicator of catabolism. A normal concentration of preal-bumin in serum is 16 to 40 mg/dL and a concentration below 8 mg/dL is consistent with severe protein-calorie malnutrition. The client's prealbumin level means that, not only does the client consume inadequate total calories, the client's intake of protein is inadequate.
1. Hemoglobin 15 g/dL is within normal limits.
3. A serum cholesterol less than 200 mg/dL is considered normal or desirable.
4. Absolute lymphocyte count ranges from 1700–3700. White blood cells are used in determining nutritional status; however, the lymphocyte count is potentially a better index of immunological status for the client.
