The nurse is calculating the one-minute Apgar score for a newborn infant and determines that the heart rate is 150 beats/minute, a vigorous cry is present, muscle tone is good with total flexion, quick reflex irritability noted, and skin color is dusky and cyanotic. Which Apgar score should the nurse assign to this infant? (Enter numeric value only.)

To determine the Apgar score for the newborn infant, we assess five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and color. Each parameter is scored from 0 to 2, with 2 being the highest score. Let's evaluate each parameter: Heart rate: 150 beats/minute --> Score of 2. Respiratory effort: Vigorous cry present --> Score of 2. Muscle tone: Good muscle tone with total flexion --> Score of 2. Reflex irritability: Quick reflex irritability noted --> Score of 2. Color: Dusky and cyanotic skin color --> Score of 1. Now, we sum up the scores: 2+2+2+2+1=92+2+2+2+1=9 Therefore, the Apgar score for this infant is 9.
