Answer:

A. Count the radial pulse for 30 seconds, if the pulse is regular, and multiply by two.

B. If irregular, auscultate the heart and count beats for 1 minute.

Explanation:

The correct answers are A and B. If the pulse is regular, by counting the heartbeat and multiplying them by two it should give you the correct heart rate, if the heart rate is irregular, auscultating the heart for a minute gives you more of an exact rate than just counting the radial pulse.
