What are the components of the APGAR scoring system?

The correct components of the APGAR scoring system are heart rate, activity (which refers to muscle tone), and respirations. This scoring system is used for assessing the health of newborns immediately after birth, typically at one and five minutes. Each component is scored on a scale from 0 to 2, with a total score possible of 10.

Heart rate is evaluated by checking if the baby has a pulse, with points awarded for a heart rate above 100 beats per minute indicating good circulation. Activity assesses the muscle tone of the infant, evaluating whether the baby is active and moving or showing limpness. Respirations measure the baby’s breathing effort, which should be strong and regular.

In this context, other answer choices include elements that are not part of the APGAR scoring system, making them unsuitable for the question. The APGAR tool specifically focuses on the immediate indicators of an infant's transition to life outside the womb, which are best represented by heart rate, activity, and respirations.
