NEONATAL NURSING EXAM — 250 Practice Questions
SECTION 1: ADAPTATION TO EXTRAUTERINE LIFE & THERMOREGULATION
(Questions 1-30)
1. A nurse is caring for a newborn in the transitional period immediately after birth.
Which of the following is the most important physiological change that must occur
for successful adaptation to extrauterine life?
A. Closure of the ductus arteriosus.
B. Establishment of effective respiration and oxygenation.
C. Initiation of gastrointestinal function.
D. Thermoregulation through nonshivering thermogenesis.
Answer: B. Rationale: While all of these are important, the establishment of effective
respiration and oxygenation is the most critical adaptation for survival, as the newborn
must transition from placental gas exchange to pulmonary gas exchange within minutes
of birth. The first breath expands the lungs, decreases pulmonary vascular resistance,
and increases pulmonary blood flow.
2. The nurse is educating a new mother about thermoregulation in the newborn.
The mother asks why her baby needs to be kept warm. Which of the following is the
most accurate explanation the nurse should provide?
A. "Newborns have immature immune systems and can easily get infections if they are
cold."
B. "Newborns have a large surface area relative to body weight and lose heat quickly."
C. "Newborns have a high metabolic rate and need extra calories to maintain body
temperature."

D. "Newborns have thick skin that prevents heat from escaping."
Answer: B. Rationale: Newborns have a large surface area relative to body weight,
minimal subcutaneous fat, and an immature thermoregulatory system. This makes
them highly susceptible to heat loss. Cold stress can lead to hypoglycemia, metabolic
acidosis, and increased oxygen consumption.
3. By keeping the nursery temperature warm and wrapping the neonate in blankets,
the nurse is preventing which type of heat loss?
A. Conduction.
B. Convection.
C. Evaporation.
D. Radiation.
Answer: B. Rationale: Convection is heat loss through air currents. Warming the
nursery and wrapping the infant in blankets prevents convective heat loss. Evaporation
is from wet skin, conduction is from direct contact with cold surfaces, and radiation is
from the infant to colder objects.
4. A nurse is caring for a newborn who has cold stress. Which of the following
findings is most consistent with cold stress in a neonate?
A. Warm trunk and warm extremities.
B. Cold trunk and cold extremities.
C. Warm trunk and cold extremities.
D. Cold trunk and warm extremities.
Answer: C. Rationale: Cold stress presents with a warm trunk and cold
peripheries (extremities). This is due to peripheral vasoconstriction in response to cold,
which preserves core temperature while the extremities become cold.
5. A newborn's mother asks why her baby is receiving a Vitamin K injection
immediately after birth. What is the best response by the nurse?
A. "Your infant needs vitamin K to develop immunity."
B. "The vitamin K will protect your infant from being jaundiced."
C. "Newborns are deficient in vitamin K, and this injection prevents abnormal bleeding."
D. "Newborns have sterile bowels, and vitamin K promotes the growth of bacteria in the
bowel."
, Page 3 of 79
Answer: C. Rationale: Newborns are deficient in vitamin K because the vitamin is
synthesized by intestinal bacteria, which are not yet established, and it does not cross
the placenta well. Vitamin K is essential for the synthesis of clotting factors. The
injection prevents Vitamin K Deficiency Bleeding (VKDB), a potentially fatal condition.
6. A nurse is preparing to perform the initial assessment on a newborn. Which of
the following is the priority nursing action immediately after birth?
A. Weigh the newborn.
B. Administer the Vitamin K injection.
C. Dry the newborn and place them skin-to-skin with the mother.
D. Assess the newborn's gestational age.
Answer: C. Rationale: Drying the newborn and placing them skin-to-
skin immediately after birth prevents evaporative heat loss, promotes bonding,
facilitates early breastfeeding, and helps stabilize the newborn's temperature, blood
glucose, and heart rate. Other assessments can be performed after the initial
stabilization.
7. The nurse is assessing a newborn's temperature. Which of the following findings
is most concerning and indicates the need for immediate intervention?
A. Axillary temperature of 98.0°F (36.7°C).
B. Axillary temperature of 97.5°F (36.4°C).
C. Axillary temperature of 96.5°F (35.8°C).
D. Axillary temperature of 99.0°F (37.2°C).
Answer: C. Rationale: A temperature of 96.5°F (35.8°C) is below the normal range for
a newborn (36.5°C-37.5°C). This indicates cold stress. Cold stress can lead to
increased oxygen consumption, hypoglycemia, metabolic acidosis, and respiratory
distress. The nurse should warm the infant immediately.
8. The nurse is teaching a mother about maintaining a neutral thermal environment
for her newborn. Which of the following statements by the mother indicates
understanding?
A. "I should keep the room temperature cool so my baby doesn't get overheated."
B. "I should dress my baby in loose clothing to allow for air circulation."
C. "I will keep my baby's room warm and dress him in a sleeper and use a blanket."
D. "I should bathe my baby immediately after birth to clean off the vernix."
, Page 4 of 79
Answer: C. Rationale: A neutral thermal environment is one in which the infant
maintains a normal core temperature with minimal oxygen consumption and caloric
expenditure. This is achieved by keeping the room warm and dressing the infant
appropriately. Bathing should be delayed until the infant's temperature is stable to
prevent evaporative heat loss.
9. A nurse is assessing a newborn who was born prematurely at 32 weeks gestation.
Which of the following is the most common cause of heat loss in a preterm infant?
A. Convection.
B. Conduction.
C. Evaporation.
D. Radiation.
Answer: C. Rationale: Evaporation is the primary mode of heat loss in preterm infants,
especially immediately after birth due to their thin skin and lack of vernix caseosa. Wet
skin on a cold surface causes rapid heat loss. Drying the infant promptly and using a
radiant warmer are critical interventions.
10. A newborn has a rectal temperature of 96.8°F (36.0°C). The nurse warms the
infant. Which of the following is the most common early sign that the infant's cold
stress is resolving?
A. The infant's skin becomes warm and pink.
B. The infant's blood glucose level rises.
C. The infant's oxygen saturation improves.
D. The infant's heart rate decreases to normal.
Answer: A. Rationale: As the infant warms, the first visible sign of improvement is the
skin becoming warm and pink as peripheral vasoconstriction reverses. Other
parameters like heart rate, respiratory rate, and blood glucose will also improve as
warming continues.
11. A nurse is reviewing the laboratory values of a newborn with cold stress. Which
of the following findings is most consistent with cold stress?
A. Metabolic alkalosis.
B. Hypoglycemia.
C. Hyperglycemia.
D. Hyperkalemia.
