Final answer:
The Apgar score is a method for evaluating fetal status based on five variables: FHR, breathing movement, gross body movement, muscle tone, and amniotic fluid volume. Scores are taken at 1 minute and 5 minutes after birth, and high scores indicate a healthy baby.
Step-by-step explanation:
Fetal evaluation based on five variables is called the Apgar score. The five variables are:
1. FHR (heart rate)
2. Breathing movement
3. Gross body movement
4. Muscle tone
5. Amniotic fluid volume
These variables are assessed at 1 minute and 5 minutes after birth, and each one is assigned a score of 0, 1, or 2. The scores are then added together, with high scores indicating a healthy baby and lower scores suggesting potential distress.
