Question: 1 / 615

What is the average pulse rate for an infant?

80-120 bpm

100-160 bpm

The average pulse rate for an infant typically falls within the range of 100 to 160 beats per minute (bpm). This range is established based on physiological norms for infants and reflects their higher metabolic and physiological demands compared to older children and adults. Infants have faster heart rates due to their smaller body size and higher activity levels, which require a more rapid blood flow to meet their developmental needs.

In contrast, the other options provide pulse rate ranges that are either too low or too high for infants. The lower ranges might apply to older children or adults, while the higher ranges could pertain to the pulse rates observed during increased activity or distress. Thus, the range of 100 to 160 bpm appropriately encompasses the normal resting heart rate for infants.
