Which pulse rate would be considered normal resting for a two-month-old infant?

• A. 90 bpm at rest
• B. 130 bpm at rest
• C. 110 bpm at rest
• D. 70 bpm at rest

Answer: (C)

Infants have higher resting heart rates than older children and adults because of their rapid metabolism and immature nervous system. For a two‑month‑old, a normal resting pulse generally falls in roughly the 100–160 beats per minute range. A resting rate around 110 bpm fits well within that range and represents a healthy, calm infant at rest. Rates well below that for a two‑month‑old, like 70 bpm, would be unusually low and warrant further evaluation, while a rate like 130 bpm is also normal but 110 is a clear, typical resting example. When checking, ensure the infant is quiet and at rest, and count for a full minute to get an accurate number.
