To receive a score of 1 on the APGAR for muscle tone, the newborn must place their extremities in what position?

The correct answer is flexion. In the context of the APGAR scoring system, muscle tone is assessed by observing the position of the newborn's extremities. A score of 1 is given when the infant's arms and legs are in a flexed position, which indicates some degree of muscle tone. This positioning reflects the newborn's ability to maintain a certain level of muscle tension and is a sign of normal neurological function.

In contrast, if the extremities were held in extension or hyperextension, this could indicate poor muscle tone or neurological dysfunction, which is not desirable. Relaxation, while indicative of low tone, also does not meet the criteria for scoring positively in this category. Recognizing these details helps in understanding the significance of muscle tone evaluation in newborns and its implications for their overall health and development.
