NSG 3500 EXAM 4 STUDY GUIDE | 2026/ ACTUAL EXAM QUESTIONS AND CORRECT
ANSWERS/GRADE A+ ASSURED/NEWEST UPDATE!!!
Question 1
At which specific intervals is the APGAR score typically assigned to a newborn?
A) Immediately at birth and at 10 minutes
B) At 1 minute and 5 minutes after birth
C) Every 5 minutes for the first 30 minutes
D) At 5 minutes and 15 minutes after birth
E) Only once at 1 minute unless the score is below 5
Correct Answer: B) At 1 minute and 5 minutes after birth
Rationale: The APGAR score is a standardized assessment used to evaluate a newborn's
transition to extrauterine life. It is performed at 1 minute to assess the initial transition and
at 5 minutes to evaluate the infant's response to any interventions and overall stability.
Question 2
Which of the following is NOT one of the five categories evaluated in an APGAR score?
A) Heart rate
B) Respiratory effort
C) Muscle tone
D) Blood glucose level
E) Generalized skin color
Correct Answer: D) Blood glucose level
Rationale: The five categories of the APGAR score are Heart Rate (HR), Respiratory
Rate/Effort (RR), Muscle Tone, Reflex Irritability (Grimace/Cry), and Color (Appearance).
Blood glucose is a laboratory assessment and not part of the APGAR scoring system.
Question 3
A nurse calculates a 5-minute APGAR score of 8. How should the nurse interpret this finding?
A) The infant is in critical condition.
B) The infant is showing a low score and needs immediate resuscitation.
C) The infant is considered normal and is transitioning well.
D) The infant requires immediate transfer to the NICU.
E) The score is invalid and must be repeated.
Correct Answer: C) The infant is considered normal and is transitioning well.
Rationale: APGAR scores are interpreted as follows: >7 is normal, 4-6 is considered low
(may require some assistance/stimulation), and <3 is critical (requires immediate
resuscitation).
Question 4
If a newborn’s APGAR score is <9 at the 5-minute mark, what is the priority nursing action?
A) Keeping the infant with the mother for skin-to-skin contact.
B) Initiating breastfeeding immediately.
C) Stabilizing the infant rather than keeping them with the mother.

D) Waiting until the 10-minute mark to reassess before acting.
E) Administering the Hepatitis B vaccine immediately.
Correct Answer: C) Stabilizing the infant rather than keeping them with the mother.
Rationale: While skin-to-skin contact is the standard for healthy newborns, a score below 9
at 5 minutes indicates the need for closer observation or intervention. Safety and
physiological stabilization take priority over maternal bonding in this specific scenario.
Question 5
Which "Chemical Factors" are responsible for triggering the initiation of a newborn's first
breath?
A) Hyperoxia and Alkalosis
B) Hypocarbia and high pH
C) Hypercarbia, acidosis, and hypoxia
D) Hypoxia and decreased aortic pressure
E) Increased magnesium and decreased potassium
Correct Answer: C) Hypercarbia, acidosis, and hypoxia
Rationale: During labor and birth, a natural decrease in oxygen (hypoxia) and an increase
in carbon dioxide (hypercarbia) lead to a drop in pH (acidosis). These chemical changes
stimulate the respiratory center in the medulla to initiate the first breath.
Question 6
How do "Mechanical Factors" assist in the respiratory transition of a newborn during a vaginal
birth?
A) The cold air in the delivery room shocks the lungs.
B) The thoracic squeeze during birth expels fluid and allows air replacement.
C) The clamping of the umbilical cord increases pulmonary pressure.
D) The use of forceps expands the chest wall.
E) The infant’s cry causes the foramen ovale to open.
Correct Answer: B) The thoracic squeeze during birth expels fluid and allows air
replacement.
Rationale: As the infant passes through the birth canal, the chest is compressed (thoracic
squeeze), forcing fetal lung fluid out of the airways. Upon delivery, the chest recoils,
drawing air into the lungs to replace the fluid.
Question 7
A nurse observes a newborn having brief respiratory pauses lasting 10 seconds without changes
in skin color or heart rate. What is the correct interpretation?
A) This is apnea of prematurity and requires caffeine.
B) This is normal "periodic breathing" for a newborn.
C) This is a sign of respiratory distress syndrome.
D) This is a critical emergency requiring a code blue.
, 3
E) This is a sign of a patent ductus arteriosus.
Correct Answer: B) This is normal "periodic breathing" for a newborn.
Rationale: Periodic breathing is common in newborns and involves pauses in breathing
lasting 5 to 15 seconds. As long as there are no associated changes in heart rate or skin
color (cyanosis), it is considered a normal transitional finding.
Question 8
Which of the following is considered a sign of respiratory difficulty in a newborn?
A) Respiratory rate of 45 breaths per minute
B) Acrocyanosis of the hands and feet
C) Expiratory grunting and nasal flaring
D) Periodic breathing pauses of 8 seconds
E) Abdominal breathing
Correct Answer: C) Expiratory grunting and nasal flaring
Rationale: Signs of respiratory distress in the neonate include apnea (pauses >20 seconds),
expiratory grunting, wheezing, nasal flaring, retractions, and the use of accessory muscles.
Question 9
For a successful cardiopulmonary adaptation, which of the following pressure changes must
occur?
A) Increased pulmonary pressure and decreased systemic pressure
B) Decreased aortic pressure and increased venous pressure
C) Increased systemic pressure and decreased pulmonary pressure
D) Increased venous pressure and decreased aortic pressure
E) Opening of the foramen ovale and ductus arteriosus
Correct Answer: C) Increased systemic pressure and decreased pulmonary pressure
Rationale: Successful transition involves the lungs expanding and pulmonary resistance
falling (decreased pulmonary pressure). Meanwhile, the loss of the low-resistance placental
circuit causes systemic vascular resistance to rise (increased systemic pressure).
Question 10
What is the expected heart rate range for a newborn immediately at birth?
A) 80–100 bpm
B) 110–130 bpm
C) 120–160 bpm
D) 160–180 bpm
E) Over 200 bpm
Correct Answer: D) 160–180 bpm
Rationale: Immediately at birth, the newborn's heart rate is typically high (160–180 bpm)
due to the stress of labor and delivery. It usually settles into the normal range of 120–160
bpm about 30 minutes after birth.
