Correct Answer is D
Explanation
A. Left bundle branch: The left bundle branch is stimulated after the atrioventricular node and bundle of His, not immediately after the sinoatrial node.
B. Purkinje fibers: The Purkinje fibers are stimulated later in the conduction pathway, after the bundle branches.
C. Right bundle branch: The right bundle branch is also stimulated after the atrioventricular node and bundle of His.
D. Atrioventricular node: After the sinoatrial node initiates the heartbeat, the electrical impulse travels to the atrioventricular node, which then passes the signal to the bundle of His and down to the bundle branches.
Correct Answer is C
Explanation
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.
