An adult's resting pulse is 52 beats per minute. How is this documented?
- Arrhythmia
- Bradycardia
- Tachycardia
- Bradypnea
Show the answer
B. Bradycardia
A heart rate under 60 is bradycardia. Bradypnea sounds similar but refers to slow breathing, and arrhythmia describes an irregular rhythm, not a slow rate.

A medical assistant finds a regular radial pulse. What is the accepted shortcut for counting it?
- Count for 10 seconds and multiply by 6
- Count for 6 seconds and multiply by 10
- Count for 30 seconds and multiply by 2
- Count for 5 seconds and multiply by 12
Show the answer
C. Count for 30 seconds and multiply by 2
With a regular rhythm, a 30-second count doubled is accurate enough. Shorter counts magnify any miscount, and an irregular pulse must be counted for a full minute.

While taking a radial pulse, the medical assistant notices the rhythm is irregular. What should be done?
- Count the pulse for one full minute
- Count for 15 seconds and multiply by 4
- Switch to the other wrist and count for 30 seconds
- Record the rate from the pulse oximeter instead
Show the answer
A. Count the pulse for one full minute
An irregular rhythm must be counted for a full 60 seconds (many offices take it apically) and the irregularity documented. Short counts multiplied up can miss or double-count the uneven beats.
