Question: 1 / 400

Which of the following would be an abnormal pulse rate for a resting adult?

55 beats per minute

80 beats per minute

120 beats per minute

A resting adult typically has a normal pulse rate ranging from 60 to 100 beats per minute. A pulse rate of 120 beats per minute is considered abnormal for a resting adult as it indicates tachycardia, which is an increased heart rate beyond the normal resting range. This could suggest an underlying medical condition, excessive physical activity, or anxiety at the time of measurement.

In contrast, pulse rates such as 55 beats per minute may be seen in trained athletes or individuals with excellent cardiovascular fitness, whereas rates like 80 beats per minute and 70 beats per minute fall well within the normal resting range for healthy adults. Understanding these ranges is essential for recognizing potential health issues and providing appropriate care.
