Question

What is the average pulse rate of new born babies (0--3 months)?

• A. 100--150
• B. 80--120
• C. 60--100
• D. 40--60

Hint:

Normal pulse rate:
• Newborns \( \rightarrow \) 100--150 bpm
• Adults \( \rightarrow \) 72 bpm approximately

Answer 1

The Correct Option is A

Concept:
Pulse rate refers to the number of heartbeats per minute. It varies depending on:
• Age
• Physical activity
• Health condition Newborn babies have a faster pulse rate compared to adults because:
• Their metabolism is high
• Growth rate is rapid
• Oxygen demand is greater The normal pulse rate of newborn babies is approximately: \[ \boxed{100-150 \text{ beats per minute}} \]

Step 1: Understand pulse rate.
Pulse is produced due to rhythmic contraction and relaxation of the heart. It can be felt at:
• Wrist
• Neck

Step 2: Understand pulse rate in infants.
Newborn babies require more oxygen and nutrients for rapid body growth. Hence: \[ \text{Heart beats faster} \] Therefore their pulse rate is much higher than adults.

Step 3: Analyze all options carefully.
Option (A): 100--150
Correct range for newborn babies. Correct. Option (B): 80--120
Closer to children or adults. Incorrect. Option (C): 60--100
Normal adult pulse rate. Incorrect. Option (D): 40--60
Very low pulse rate. Incorrect.

Step 4: Choose the correct answer.
Thus, average pulse rate of newborn babies is: \[ \boxed{100-150} \] Hence, \[ \boxed{(1)\ 100-150} \]
