Final answer:
The newborn's Apgar score, calculated using the provided criteria, is 9 at 1 minute after birth. This score suggests that the baby is in a generally good physical condition as it is above the normal threshold of 7.
Step-by-step explanation:
The Apgar score is a quick test performed on a newborn at 1 minute and again at 5 minutes after birth to determine the physical condition of the baby and if immediate medical care is necessary. Each of the five criteria - appearance (skin color), pulse (heart rate), grimace (reflex irritability), activity (muscle tone), and respiration - are scored on a scale of 0 to 2, with a maximum total score of 10 indicating optimal physical condition.
We can assess the infant's score with the given information as follows:
- Appearance: Trunk is pink but extremities are blue, which scores 1 point.
- Pulse: Heart rate is 110 bpm, which scores 2 points (normal is over 100 bpm).
- Grimace: Infant cries on stimulation which scores 2 points.
- Activity: Limbs are flexed which scores 2 points.
- Respiration: Infant is crying vigorously, which scores 2 points.
Adding these together, the infant's Apgar score is 9 at 1 minute. This score is considered normal as it is above 7, indicating that the baby is in a good physical state post-delivery.
