A 1-minute Apgar score of 3 indicates severe distress. Which observation would most likely be present in the newborn?

• A. Muscle tone flaccid
• B. Heart rate 126 bpm
• C. Respirations 42 breaths per minute
• D. Blood pressure 60 mm Hg systolic

Answer: (A)

Think about Apgar scoring: it evaluates five signs—pulse, respiration, muscle tone, reflex irritability, and color—each scored 0, 1, or 2, for a total of up to 10. A 1-minute score of 3 signals severe distress, and the muscle tone component is typically the most affected in such cases. Flaccid, limp muscles indicate very low activity and would contribute 0 points for muscle tone, which fits a low overall score like 3. In contrast, a heart rate of 126 bpm is well within the normal newborn range and would usually earn a score of 2 for pulse; a respiration rate of 42 breaths per minute is also within normal limits and would not alone account for a low score. Blood pressure isn’t part of the Apgar assessment. So the most likely observation with severe distress is flaccid muscle tone.
