A nurse is creating a nutritional plan of care for a child. Which of the following diagnostic tests should the nurse plan to monitor for the child?

A. Complete blood count: A CBC provides information about hemoglobin, hematocrit, and red and white blood cell counts, which can reflect nutritional status. Low hemoglobin or hematocrit may indicate iron deficiency anemia, while changes in white blood cells could suggest protein-calorie malnutrition or immune compromise. B. Cardiac enzymes: Cardiac enzymes, such as troponin and CK-MB, are used to assess myocardial injury and are not related to routine nutritional monitoring in children. C. Blood coagulation tests: Coagulation studies evaluate clotting function and liver-related disorders. While vitamin K deficiency may affect clotting, these tests are not primary indicators for overall nutritional assessment. D. Arterial blood gases: ABGs measure acid-base balance and oxygenation status. They are not standard tests for evaluating nutritional status unless there is a specific metabolic concern.
