Final answer:
A nurse reviewing lab findings of a client with protein-calorie malnutrition should expect decreased albumin levels.
Step-by-step explanation:
The nurse should expect decreased albumin as a finding in a client with protein-calorie malnutrition. Protein-calorie malnutrition refers to a condition where the body does not receive adequate amounts of protein and calories, leading to a deficiency. Since albumin is a protein found in the blood, a decrease in albumin levels would be expected in this condition.
