NUR 230 Exam 4 Questions and Correct Answers plus
Rationale| New 2026-2027 Update | Graded A+
1. Which of the following best describes the primary purpose of the Apgar
score?
A) To evaluate a newborn's immediate adjustment to extrauterine life
B) To assess long-term cognitive development in newborns
C) To determine the need for surgical intervention after birth
D) To measure the newborn's birth weight and length
Correct Answer: To evaluate a newborn's immediate adjustment to extrauterine
life
Rationale: The Apgar score assesses heart rate, respiratory effort, muscle tone,
reflex irritability, and color at 1 and 5 minutes after birth. It provides a quick,
standardized evaluation of how well the newborn is transitioning to life outside
the uterus and identifies those needing immediate resuscitation.
2. What is the primary function of the "5 S's" technique in newborn care?
A) To soothe and calm a crying infant
B) To assess newborn reflexes
C) To evaluate gestational age
D) To screen for developmental delays
Correct Answer: To soothe and calm a crying infant
Rationale: The "5 S's"—Swaddling, Side/stomach position, Shushing, Swinging,
and Sucking—are techniques developed by Harvey Karp to activate the newborn
calming reflex. They mimic the conditions of the womb and help soothe crying
infants. They are not used for assessment or screening.
3. According to the exam blueprint, which medication is contraindicated for a
newborn experiencing alcohol withdrawal syndrome?
,A) Morphine
B) Methadone
C) Narcan
D) Phenobarbital
Correct Answer: Narcan
Rationale: Narcan (naloxone) is an opioid antagonist and is contraindicated in
newborns with alcohol withdrawal syndrome because it can precipitate acute
withdrawal symptoms and seizures. Morphine, methadone, and phenobarbital are
used to manage withdrawal symptoms.
4. What is the term for a newborn's first bowel movement, which should
occur within the first 12 hours of life?
A) Meconium
B) Nevi simplex
C) Meningocele
D) Erythromycin
Correct Answer: Meconium
Rationale: Meconium is the first stool passed by a newborn, consisting of amniotic
fluid, mucus, and bile. It is dark green to black and sticky. Passage within the first
12 hours indicates a patent gastrointestinal tract.
5. Which condition is a bluish-black spot near the buttocks that is benign and
commonly seen in newborns with darker skin tones?
A) Mongolian spot
B) Nevus simplex
C) Erythema toxicum
D) Milia
Correct Answer: Mongolian spot
Rationale: Mongolian spots are benign, bluish-black pigmented lesions commonly
found on the buttocks and lower back of newborns with darker skin. They result
from melanocytes in the dermis and usually fade during childhood.
, 6. What is the primary purpose of administering vitamin K to a newborn after
birth?
A) To prevent hemorrhagic disease of the newborn
B) To promote bone development
C) To boost the immune system
D) To prevent jaundice
Correct Answer: To prevent hemorrhagic disease of the newborn
Rationale: Newborns are at risk for vitamin K deficiency bleeding because they
have low vitamin K stores and their intestines are sterile. A single intramuscular
dose of vitamin K at birth prevents this potentially fatal bleeding disorder.
7. Which finding is most consistent with fetal alcohol syndrome?
A) Smooth philtrum and thin upper lip
B) Large head circumference and macrosomia
C) Hyperactivity and increased attention span
D) Tall stature and advanced bone age
Correct Answer: Smooth philtrum and thin upper lip
Rationale: Fetal alcohol syndrome is characterized by specific facial features,
including a smooth philtrum, thin upper lip, and short palpebral fissures. It also
causes growth restriction and central nervous system abnormalities.
8. What is the biggest physiological impact caused by fetal alcohol syndrome?
A) Central nervous system damage
B) Gastrointestinal dysfunction
C) Renal failure
D) Cardiac arrhythmias
Correct Answer: Central nervous system damage
Rationale: The most significant and permanent effect of fetal alcohol syndrome is
damage to the central nervous system, leading to cognitive deficits, behavioral
problems, and developmental delays. Alcohol is a teratogen that crosses the
placenta and interferes with fetal brain development.
, 9. Which condition is characterized by a newborn's head circumference being
significantly below normal for gestational age?
A) Microcephaly
B) Macrocephaly
C) Hydrocephalus
D) Craniosynostosis
Correct Answer: Microcephaly
Rationale: Microcephaly is a condition in which the newborn's head
circumference is significantly smaller than expected for gestational age. It can
result from genetic factors, infections, or teratogen exposure and is often
associated with developmental delays.
10.What is the primary purpose of the newborn screening test?
A) To detect metabolic and genetic disorders early
B) To diagnose acute infections
C) To assess hearing acuity
D) To evaluate cardiac function
Correct Answer: To detect metabolic and genetic disorders early
Rationale: Newborn screening tests, typically performed via a heel stick, detect
metabolic disorders such as phenylketonuria (PKU), congenital hypothyroidism,
and sickle cell disease. Early detection allows for prompt treatment and
prevention of serious complications.
11.Which condition is a birth defect characterized by the spinal cord and
meninges protruding through an opening in the spine?
A) Spina bifida
B) Anencephaly
C) Hydrocephalus
D) Encephalocele
Correct Answer: Spina bifida
Rationale: Spina bifida is a neural tube defect in which the spinal cord and
meninges protrude through an opening in the vertebral column. It can vary in
