A major concern for an 86-year-old patient who has been NPO for 8 hours prior to a diagnostic test would be:

hydration status.

nutritional status.

circulatory status.

fatigue.

Answer and Explanation

The Correct Answer is A

A. Hydration status: Older adults are at increased risk of dehydration due to decreased thirst perception and potential underlying conditions. Prolonged NPO status exacerbates this risk.

B. Nutritional status: While important, 8 hours of fasting does not significantly affect nutrition.

C. Circulatory status: This would not typically be affected solely by NPO status unless dehydration becomes severe.

D. Fatigue: Though possible, it is less critical than hydration status.
