Multiple Choice

Which of the following respiratory rates should be cause for alarm in a 2-month-old child?

40 breaths per minute

10 breaths per minute

30 breaths per minute

50 breaths per minute

Verified step by step guidance

Step 1: Understand the normal respiratory rate for a 2-month-old child. Typically, the normal range is between 30 to 60 breaths per minute. This is higher than the respiratory rate for adults due to the child's smaller lung capacity and higher metabolic rate.

Step 2: Evaluate each option provided in the problem. Compare the given respiratory rates (10, 30, 40, and 50 breaths per minute) to the normal range for a 2-month-old child.

Step 3: Identify any respiratory rate that falls outside the normal range. For example, a rate of 10 breaths per minute is significantly below the normal range and could indicate respiratory distress or other medical concerns.

Step 4: Consider the implications of a respiratory rate that is too high or too low. A rate below 30 breaths per minute or above 60 breaths per minute may require immediate medical attention.

Step 5: Conclude that the respiratory rate of 10 breaths per minute is cause for alarm, as it is far below the normal range for a 2-month-old child and could indicate a serious issue requiring prompt evaluation by a healthcare professional.
