A patient is suspected of having protein calorie malnutrition (PCM) with a body mass index of less than 18. Which laboratory tests should the nurse expect to be prescribed for this patient?
Select all that apply.
1. serum albumin
2. lymphocyte count
3. serum electrolytes
4. complete blood count (CBC)
5. Urinalysis
Correct Answer: 1, 2, 3
In PCM, serum albumin and lymphocytes count are reduced. Serum electrolytes are measured and potassium levels are low in severe malnutrition. While a CBC and urinalysis are important measures, they are not necessarily useful in determining protein calorie malnutrition.
