Which of the following is an EKG test that is performed as the patient is on a treadmill?

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.

A. Place a pulse oximeter on the patient's earlobe: A pulse oximeter measures oxygen saturation and pulse but is not used for manually palpating the pulse.
B. Palpate the patient's radial artery: The radial artery, located at the wrist, is commonly palpated to manually obtain the pulse.
C. Place a pulse oximeter on the patient's finger: A pulse oximeter measures pulse rate and oxygen saturation but does not involve manual palpation.
D. Palpate the patient's popliteal artery: The popliteal artery is located behind the knee and is less commonly used for routine pulse measurement compared to the radial artery.
