Which of the following indicates a score of 2 for muscle tone in the Apgar assessment?

In the Apgar assessment, muscle tone is scored based on the baby's extremities' movement. A score of 2 indicates that the infant exhibits active motion. This means that the baby demonstrates a good level of activity and muscle strength, which is a positive sign of neurological function. Active motion suggests not only healthy muscle tone but also responsiveness to stimuli, reflecting the newborn's overall well-being.

The other options reflect varying degrees of muscle tone. Flaccid limbs suggest no muscle tone, leading to a score of 0. Absent movement would also signify a lack of tone, indicating a 0 score. Flexion of extremities suggests a better-than-flaccid condition but is not as strong as active motion, which would typically receive a score of 1. Overall, a score of 2 for muscle tone in the Apgar assessment represents the best outcome, highlighting the newborn's active engagement and normal muscle function.
