NOT a component of a micronutrient assessment in PN patients?

• A. Genetic history
• B. Review nutrient intake
• C. Potential nutrient losses
• D. Medications

Answer: (A)

In PN patients, the micronutrient assessment centers on factors that directly affect current micronutrient status and needs: what the patient is actually consuming (review of nutrient intake, including any EN/PN contributions and oral intake), what is being lost (potential nutrient losses from GI losses, drainage, dialysis, diuresis), and what medications might alter micronutrient levels or interactions (drug-induced depletions or chelation). These elements actively shape supplementation decisions and adjustments to the PN plan.

Genetic history, while relevant to overall care in some contexts, does not provide direct, actionable information about a patient’s current micronutrient status or immediate needs in PN. It may influence long-term disease risk but is not a standard component used to gauge or guide micronutrient supplementation in PN therapy.

Thus, genetic history is not a typical component of the micronutrient assessment in PN patients.
