Question

Normal heart rate in a two-month-old infant is
A)<72/min
B)60 to 72/min
C)>72/min
D)16/min

Answer 1

Hint: The times our heartbeats each minute is called a heart rate and it is also known as a pulse rate. When the child is active the heart beats faster and when they are seated asleep it becomes lower. The fluctuation in the rate of the heartbeat is changed depending on the daily activities.

Complete answer
-The number of heartbeats per minute is known as the heartbeat. Back of the knees, Groin, Neck, Ankle, The top or inner side of the foot, are the areas where an artery passes close to the skin.
-Place the index and middle finger over the underside of the opposite wrist below the base of the thumb to measure the pulse at the wrist and press there until you feel the pulse.
-Place the index and the middle finger to the side of the Adam's Apple to measure the pulse on the neck and press firmly until you locate the pulse.
-When the pulse is observed, for one full minute count the beats and multiply by 2. This gives the beat per minute.
-2-month-old infants have a higher heart rate i.e 100-150 per minute due to body metabolism is faster than adults.
-As a child grows (ten years), like an adult their heartbeat comes in the same range. The pulse rate is measured in a child's resting position when he is not crying, running, or playing.
-About 50 million times heartbeats in a child first year of life

Additional information
For resting heart rate, normal values are
Newborns have 100 - 150 beats per minute
Infants (3 - 6 months old) have 90 - 120 beats per minute
Infants (6 - 12 months old) have 80 - 120 beats per minute
Children 1 - 10 years have 70 - 130 beats per minute
Children over 10 and adults (including seniors) have 60 - 100 beats per minute
Well-trained athletes have 40 - 60 beats per minute

So, the correct answer is,”<72/min”.

Note
-Resting heart rate in a newborn is about 130 beats per minute whereas the child normal heartbeat range is around 80 to 100 and adults have 70 to 90.
-When the baby is not crying or having a fever then the heart rate can rise to 160 beats per minute.
-Because of the higher metabolism, babies and children up to two years old have higher heart rate
