Which of the following is a component of the micronutrient assessment in PN patients?

• A. Medical and surgical history
• B. Nutritional counseling
• C. Medical and surgical history
• D. Imaging studies

Answer: (C)

A thorough micronutrient assessment in PN patients starts with gathering a complete medical and surgical history. This history reveals factors that influence micronutrient needs and absorption, such as prior gastrointestinal surgeries that bypass or remove absorption sites (eg, gastrectomy, small-bowel resection, bariatric procedures), chronic GI diseases, liver or renal conditions, alcohol use, inflammatory illnesses, or prior parenteral nutrition exposure. These factors help identify which micronutrients to monitor, which laboratory tests to prioritize, and how aggressively to supplement.

Imaging studies can show structural issues or complications but do not measure micronutrient status. Nutritional counseling is important for ongoing care but is not the component used to assess micronutrient status itself.
