A medical assistant is preparing a patient for a spirometry test. The assistant should remind the patient that which of the following could affect the test result?
A. Taking aspirin within 12 hr of testing
Taking aspirin within 12 hr of testing: Aspirin does not generally affect spirometry results.
B. Using sedatives within 1 hr of testing
Using sedatives within 1 hr of testing: Sedatives may affect respiratory function, but they are not a common consideration for spirometry preparation.
C. Exercising 2 hr prior to testing
Exercising 2 hr prior to testing: Exercise can affect lung function temporarily, so it’s best to avoid vigorous exercise before a spirometry test.
D. Eating a heavy meal 4 hr prior to testing
Eating a heavy meal 4 hr prior to testing: While eating a heavy meal might cause some discomfort, it is less likely to affect the spirometry results significantly compared to exercise.
