Solution
To determine which of the following is an abnormal finding, we need to assess each option and compare it to the expected values for the corresponding age group.
a. Heart rate of 80 beats/min in a 3-month-old infant: The normal heart rate for a 3-month-old infant is typically between 100-150 beats per minute. Therefore, a heart rate of 80 beats/min in a 3-month-old infant would be considered abnormal.
b. Systolic BP of 100 mm Hg in a 10-year-old child: The normal systolic blood pressure for a 10-year-old child is typically around 90-110 mm Hg. A systolic blood pressure of 100 mm Hg falls within the normal range for this age group, so it would not be considered abnormal.
c. Rapid, irregular breathing in a newly born infant: Rapid and irregular breathing is common in newborn infants due to their immature respiratory system. Therefore, this finding would be considered normal for a newly born infant.
d. Respiratory rate of 26 breaths/min in a 2-year-old child: The normal respiratory rate for a 2-year-old child is typically between 20-30 breaths per minute. A respiratory rate of 26 breaths/min falls within the normal range for this age group, so it would not be considered abnormal.
Based on the above analysis, the abnormal finding would be a heart rate of 80 beats/min in a 3-month-old infant (option a).
