RNC-MNN TEST PREP EXAM QUESTIONS (LATEST 2025/2026 UPDATE) WITH WELL
EXPLAINED SOLUTIONS
According to the March of Dimes, there may be four main routes to spontaneous premature
labor. They include all except which of the following?
a. infections or inflammation
b. maternal or fetal stress
c. diabetes
d. bleeding
c. diabetes
Diabetes is not a route considered. The fourth route is uterine stretching. Overdistention of
the uterus due to multiple gestation, or placental abnormalities can lead to the release of
chemicals that stimulate uterine contractions.
An incubator or isolette warms the infant by which of the following?
a. radiation
b. conduction combined with radiation
c. convection
d. convection combined with radiation
c. convection
An incubator or isolette warms the infant by convection. A radiant warmer is an open bed
with radiant heat panels placed above the infant so that convective and evaporative heat
losses are increased. Once an infant's temperature is normalized, the infant is placed in an
open crib with hats and blankets providing thermal support.
,The newborn's general body response to sudden stimulus that is a combination of full
extension and abduction of limbs is which of the following reflexes?
a. rooting
b. Babinski reflex
c. Moro reflex
d. palmar reflex
c. Moro reflex
The Moro reflex is also called the startle reflex. It is the newborn's general body response to
sudden stimulus that is a combination of full extension and abduction of limbs. The Moro
reflex is one of many reflexes that are seen at birth. It normally disappears after 3 or 4
months.
Which of the following statements about mastitis in postpartum women is least accurate?
a. mastitis usually occurs approximately 2-3 weeks after birth
b. the infection involves the interlobular connective tissue
c. the infection usually involves only one breast
d. mastitis may occur as early as the first postpartum day
d. mastitis may occur as early as the first postpartum day
Mastitis usually occurs approximately 2-3 weeks after birth and may occur as early as the
seventh postpartum day. Predisposing factors include milk stasis (from a blocked duct),
nipple trauma (cracked or fissured nipples), and poor breastfeeding technique.
,The cardinal symptoms of a postpartum infection are
a. elevated temperature, tachycardia, and pain
b. elevated temperature, bradycardia, and pain
c. elevated temperature, hypotension, and skin pallor
d. elevated temperature, tachycardia, and skin pallor
a. elevated temperature, tachycardia, and pain
The nursery should be notified of these findings, although the newborn need not be
separated from the mother.
The newborn's chest is cylindrical. Measured at the nipple line, its circumference is
approximately
a. 25 cm
b. 22 cm
c. 38 cm
d. 33 cm
d. 33 cm
This is 2-3 cm less than the infant's head.
, Which of the following statements about thermoregulation in terms of a newborn is least
accurate?
a. the newborn's ability to maintain temperature control after birth is determined by
external environmental factors and internal physiologic processes
b. characteristics of newborns that predispose them to heat loss include a large body
surface area in relation to body mass and a limited amount of subcutaneous fat
c. peripheral vasoconstriction increases heat loss to the skin surface
d. evaporation is a mechanism of heat loss
c. peripheral vasoconstriction increases heat loss to the skin surface
Peripheral vasoconstriction decreases (not increases) heat loss to the skin surface.
Newborns attempt to regulate body temperature through thermogenesis, increased
metabolic rate, and increased muscle activity.
A benign, self-limited, asymptomatic skin condition that only occurs during the neonatal
period characterized by erythematous papules, vesicles, and occasionally, pustules is
which of the following
a. petechiae
b. hemangiomas
c. erythema toxicum
d. cafe au lait spots
c. erythema toxicum
The eruption is characterized by small, erythematous papules, vesicles, and occasionally,
pustules. The lesions are usually surrounded by a distinctive diffuse, blotchy,
