Final answer:
The newborn's Apgar score is 6(46%) option (3), which is calculated based on the five criteria: appearance, pulse, grimace, activity, and respiration. The score suggests the baby is in the borderline range and may require some medical assistance. A follow-up assessment will be important for determining additional needs.
Step-by-step explanation:
The nurse should assign an Apgar score of 6(46%) option (3) to this newborn. According to the five criteria used for the Apgar assessment - appearance (skin color), pulse (heart rate), grimace (reflex), activity (muscle tone), and respiration - the newborn's scores are:
- Appearance: Completely blue indicating a score of 0.
- Pulse: Heart rate of 110/min, which warrants a score of 2.
- Grimace: Newborn grimaces when nares are suctioned, earning a score of 1.
- Activity: Active movement and flexion of extremities, indicating a score of 2.
- Respiration: A weak cry, denoting a score of 1.
These individual scores add up to a total Apgar score of 6 (0 + 2 + 1 + 2 + 1 = 6). While a score of 7 or higher is considered normal, a score of 6 suggests that the newborn is in the borderline range in terms of immediate well-being, and they might need some medical assistance but not necessarily an emergency situation. Further evaluation at the 5-minute mark will be important for determining the need for additional medical intervention.
