Apgar score < 3 at 5 minutes of life is a predictor of:
**Core Concept**
The Apgar score is a method used to quickly summarize the health of newborn children against infant mortality. It assesses heart rate, muscle tone, reflexes, respiratory effort, and skin color. An Apgar score of less than 3 at 5 minutes of life is a critical indicator of a newborn's need for immediate medical attention.
**Why the Correct Answer is Right**
An Apgar score of less than 3 indicates severe distress, primarily due to respiratory and cardiovascular compromise. Newborns with such a low score are at a higher risk of mortality and morbidity. This is because the heart rate, which accounts for the largest portion of the Apgar score, is severely compromised. Newborns with an Apgar score of less than 3 often require resuscitation and close monitoring to prevent long-term complications.
**Why Each Wrong Option is Incorrect**
**Option A:** While an Apgar score of less than 7 at 5 minutes is concerning, it is not as strongly predictive of mortality as a score of less than 3.
**Option B:** An Apgar score of less than 3 does not directly predict the need for surgical intervention in newborns.
**Option C:** While an Apgar score of less than 3 is a predictor of short-term mortality, it is not a reliable predictor of long-term neurological outcomes.
**Clinical Pearl / High-Yield Fact**
An Apgar score of less than 3 at 5 minutes of life is a critical indicator of a newborn's need for immediate medical attention, and it is essential to perform resuscitation and close monitoring to prevent long-term complications.
**Correct Answer:** C. Mortality
