Correct Answer is C
Explanation
Correct answer: C
A. Taking aspirin within 12 hr of testing: Aspirin does not generally impact spirometry results.
B. Using sedatives within 1 hr of testing: While sedatives might affect breathing, they are not commonly noted as a significant factor for spirometry test preparation.
C. Exercising 2 hr prior to testing: Exercise can temporarily affect lung function, so it's advised to avoid vigorous exercise before a spirometry test to ensure accurate results.
D. Eating a heavy meal 4 hr prior to testing: Although a heavy meal might cause some discomfort, it is less likely to affect the spirometry results compared to exercise.
