A 10-month-child weighing 5 kg and with 65 cm length, presents with cough and cold. He was found to have a respiratory rate of 48 per minute with no retractions, grunting, cyanosis. There is no history of convulsions. Which is true?
**Core Concept:** Respiratory rate is a vital sign that reflects the efficiency of respiration in maintaining oxygenation. In children, respiratory rate greater than 40-45 per minute is considered abnormal.
**Why the Correct Answer is Right:** In the given scenario, the child has a respiratory rate of 48 per minute, which is above the normal range for an 10-month-old child (40-45 per minute). This abnormality indicates the need for further evaluation and management of the child's condition.
**Why Each Wrong Option is Incorrect:**
A. **False:** The respiratory rate is elevated, not within the normal range.
B. **False:** The presence of retractions, grunting, or cyanosis would be more concerning and justify a higher priority in diagnosis.
C. **False:** The absence of convulsions does not rule out the possibility of a serious underlying condition causing respiratory distress.
D. **False:** The respiratory rate is elevated, not within the normal range.
**Why the Correct Answer is Right:**
The correct answer is chosen because the respiratory rate is elevated (48 per minute) and this is the only option that correctly states the observed value. The other options either mention incorrect values (options A, B, and D) or irrelevant findings (option C).
**Clinical Pearl:** In children with respiratory distress, it is essential to evaluate for other signs (i.e., retractions, grunting, cyanosis, and convulsions) and consider the underlying cause. This could be due to a variety of conditions, such as pneumonia, bronchiolitis, asthma, or congenital heart disease, among others. A thorough clinical examination and further investigations are necessary to determine the underlying cause and initiate appropriate management.
