Arizona Certified Nursing Assistant (CNA) Practice Test

When counting a resident's pulse, the nurse aide should notice what aspect of the heartbeat?

1. If the pulse is strong or weak

2. If the rhythm of the heart-beat is regular

3. If the pulse is fast or slow

4. If the pulse is steady

The correct answer is: If the rhythm of the heart-beat is regular

When counting a resident's pulse, it is important to assess the rhythm of the heartbeat. A regular rhythm indicates that the heart is beating in a consistent and predictable pattern, which is a sign of a healthy cardiovascular system. Any irregularities could suggest underlying health issues that may require further evaluation. Monitoring the rhythm helps in identifying abnormalities such as arrhythmias, which can impact a patient's health. While aspects such as the strength of the pulse, its speed, and whether it is steady are also relevant to understanding a person's cardiovascular health, the rhythm specifically gives insight into the regularity and function of the heart's electrical conduction. A consistent rhythm is crucial for effective blood circulation and overall health, making this aspect particularly significant during pulse assessment.
