The normal range of respiratory rate in the newborn is.. 30 - 60 B/m

The normal range of respiratory rate in  the newborn is:

• A- 50 – 100 B/m
• B- 30 – 60 B/m
• C- 15 – 25 B/m
• D- 12– 20 B/m

The normal range of respiratory rate in a newborn is: B. 30 – 60 breaths per minute (B/m)

Here's why:

- Option A (50 – 100 B/m):

This is too high for a healthy newborn. A respiratory rate consistently above 60 B/m could indicate respiratory distress and requires medical evaluation.

- Option C (15 – 25 B/m):

This is too low for a healthy newborn. A respiratory rate below 30 B/m is concerning and requires immediate medical attention.

- Option D (12– 20 B/m):

This is also too low for a healthy newborn. Similar to option C, a respiratory rate below 30 B/m necessitates immediate medical attention.

Therefore, a newborn's respiratory rate falling within the range of 30-60 breaths per minute is considered normal and healthy. However, it's important to remember that individual variations can exist, and any significant deviations from this range, especially persistent ones, warrant prompt medical evaluation.
