APGAR Score: the method, the errors, and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
The APGAR score is assessed at one and five minutes after birth, scoring heart rate, respiratory effort, muscle tone, reflex irritability and colour from 0 to 2 each. It describes how well the newborn is transitioning to extrauterine life at that moment, not a prediction of long-term outcome.
Why this skill decides answers
APGAR shows up constantly on the NCLEX because it forces you to prioritise in a compressed time window, and prioritisation is what the exam tests. A newborn with a low one-minute score who improves by five minutes is a different clinical picture than one who stays low, and questions are built around that distinction.
Getting the timing wrong, treating it as a single score or as something done once at birth, leads to wrong answers even when you know the scoring criteria. The skill is not memorising the five categories in isolation; it is knowing what the score at each timepoint tells you to do next.
How to do it reliably
Score five categories, each worth 0, 1 or 2: heart rate, respiratory effort, muscle tone, reflex irritability, and colour. Heart rate is assessed by auscultation or palpation of the umbilical cord, not by feel alone, and above 100 beats per minute scores 2.
Do the first assessment at exactly one minute of life and the second at five minutes. If the five-minute score is below 7, continue scoring every five minutes for up to 20 minutes while resuscitation continues, since a single low score at five minutes is not the end of the assessment. Score what you see at that moment, not what you expect or what the trend suggests; each timepoint stands alone.
The common errors
The most frequent error is treating APGAR as a resuscitation decision tool. It is not. Resuscitation starts based on immediate assessment of breathing, tone and heart rate at birth, before the one-minute APGAR is even calculated, so do not wait for a score to act on an obviously non-breathing infant.
Another common error is scoring colour rigidly. Acrocyanosis, blue hands and feet with a pink body, is normal and common in the first minutes and scores a 1, not a 0. Students also confuse reflex irritability with muscle tone; irritability is the response to stimulation such as suctioning or a foot flick, while tone is the baseline flexion observed independent of stimulation.
Drills that build it
Practise scoring from short case vignettes rather than static tables. Give yourself a description, heart rate 130, irregular slow respirations, some flexion, grimace to stimulation, body pink with blue extremities, and force yourself to assign each category a number before checking the total.
Pair every practice score with the follow-up action. If the one-minute score is 4, what happens next; if the five-minute score is 6, what happens next. The exam rewards knowing the response, not just the arithmetic, so drill the two together every time.
Exam application
Expect questions that give you a scenario and ask you to calculate the score, and expect others that give you the score and ask what it means clinically. A score of 7 to 10 at five minutes is considered normal transition; 4 to 6 is moderately depressed and needs continued support; 0 to 3 is severely depressed and needs ongoing resuscitation and scoring.
Watch for distractor answers that treat a low one-minute score as predictive of poor long-term outcome. NCLEX writers use this deliberately, because it is a real misconception. The correct framing is always that APGAR describes the transition at that moment and guides immediate care, not a prognosis.
Quick reference
Heart rate: 0 for absent, 1 for below 100, 2 for 100 or above. Respiratory effort: 0 for absent, 1 for slow or irregular, 2 for good, crying.
Muscle tone: 0 for limp, 1 for some flexion, 2 for active motion. Reflex irritability: 0 for no response, 1 for grimace, 2 for cry or active withdrawal. Colour: 0 for blue or pale all over, 1 for body pink with blue extremities, 2 for completely pink. Assess at one minute and five minutes, and continue every five minutes past that if the score stays below 7.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our maternity and newborn practice questions are the closest set to what this page covers.
Common questions
Do you wait for the APGAR score before starting resuscitation?
No. Resuscitation begins based on immediate assessment of breathing, tone and heart rate right after birth. The one-minute APGAR score is calculated alongside or after resuscitation has already started if the infant needs it, never as a prerequisite.
Does a low APGAR score at one minute predict long-term outcome?
No. It describes the newborn's transition at that specific moment. A low one-minute score that rises by five minutes usually indicates a normal transition after brief support, and even persistently low scores are only one factor among many in longer-term outcomes.
Why is acrocyanosis scored as 1, not 0, for colour?
Acrocyanosis, blue hands and feet with a pink trunk, reflects normal peripheral circulatory adjustment in the first minutes of life. A 0 is reserved for an infant who is blue or pale over the entire body, which signals more significant compromise.
What do you do if the five-minute APGAR score is still below 7?
Continue resuscitative efforts as indicated and repeat the APGAR score every five minutes up to 20 minutes total. Document each score and the interventions given between assessments, since this trend guides the ongoing care plan.
