QUESTIONS AND ANSWERS ( NEW FULL EXAM )
GUARANTEED A+
1. A newborn who has an asymmetrical Moro reflex response should be
further assessed for which of the following?
o A. Talipes equinovarus
o B. Fractured clavicle
o C. Congenital hypothyroidism
o D. Increased intracranial pressure
Answer
Correct Answer: B. Fractured clavicle
A fractured clavicle would prevent the normal Moro response of
symmetrical sequential extension and abduction of the arms followed by
flexion and adduction.
• Option A: In talipes equinovarus (clubfoot) the foot is turned
medially, and in plantar flexion, with the heel elevated. The
feet are not involved with the Moro reflex.
• Option C: Hypothyroidism has no effect on the primitive
reflexes. Hypothyroidism means that the thyroid gland can’t
make enough thyroid hormones to keep the body running
normally.
• Option D: The absence of the Moro reflex is the most
significant single indicator of central nervous system status,
but it is not a sign of increased intracranial pressure.
2. 2. Question

During the first 4 hours after a male circumcision, assessing for which of
the following is the priority?
o A. Infection
o B. Hemorrhage
o C. Discomfort
, o D. Dehydration
Answer
Correct Answer: B. Hemorrhage
Hemorrhage is a potential risk following any surgical procedure. Although
the infant has been given vitamin K to facilitate clotting, the prophylactic
dose is often not sufficient to prevent bleeding.
• Option A: Although infection is a possibility, signs will not
appear within 4 hours after the surgical procedure.
• Option C: The primary discomfort of circumcision occurs
during the surgical procedure, not afterward.
• Option D: Although feedings are withheld prior to the
circumcision, the chances of dehydration are minimal.
3. 3. Question

The mother asks the nurse. “What’s wrong with my son’s breasts? Why are
they so enlarged?” Which of the following would be the best response by
the nurse?
o A. “The breast tissue is inflamed from the trauma experienced with
birth.”
o B. “A decrease in material hormones present before birth causes
enlargement,”
o C. “You should discuss this with your doctor. It could be a
malignancy.”
o D. “The tissue has hypertrophied while the baby was in the uterus.”
Answer
Correct Answer: B. “A decrease in material hormones present before
birth causes enlargement,”
The presence of excessive estrogen and progesterone in the maternal-fetal
blood followed by prompt withdrawal at birth precipitates breast
engorgement, which will spontaneously resolve in 4 to 5 days after birth.
• Option A: The trauma of the birth process does not cause
inflammation of the newborn’s breast tissue.
, • Option C: Newborns do not have breast malignancy. This
reply by the nurse would cause the mother to have undue
anxiety.
• Option D: Breast tissue does not hypertrophy in the fetus or
newborns.
4. 4. Question

Immediately after birth, the nurse notes the following on a male newborn:
respirations 78; apical heart rate 160 BPM, nostril-flaring; mild intercostal
retractions; and grunting at the end of expiration. Which of the following
should the nurse do?
o A. Call the assessment data to the physician’s attention
o B. Start oxygen per nasal cannula at 2 L/min.
o C. Suction the infant’s mouth and nares.
o D. Recognize this as a normal first period of reactivity.
Answer
Correct Answer: D. Recognize this as normal first period of reactivity
The first 15 minutes to 1 hour after birth is the first period of reactivity
involving respiratory and circulatory adaptation to extrauterine life. The
data given reflect the normal changes during this time period.
• Option A: The infant’s assessment data reflect normal
adaptation. Thus, the physician does not need to be notified.
• Option B: Babies with heart or lung problems may need to
breathe increased amounts of oxygen to get normal levels of
oxygen in their blood. Oxygen therapy provides babies with
extra oxygen.
• Option C: The data do not indicate the presence of choking,
gagging, or coughing, which are signs of excessive secretions.
Suctioning is not necessary.
5. 5. Question
1 point(s)
The nurse hears a mother telling a friend on the telephone about umbilical
cord care. Which of the following statements by the mother indicates
effective teaching?
, o A. “Daily soap and water cleansing is best.”
o B. “Alcohol helps it dry and kills germs.”
o C. “An antibiotic ointment applied daily prevents infection.”
o D. “He can have a tub bath each day.”
Answer
Correct Answer: B. “Alcohol helps it dry and kills germs”
Application of 70% isopropyl alcohol to the cord minimizes
microorganisms (germicidal) and promotes drying. The cord should be
kept dry until it falls off and the stump has healed.
• Option A: Research now shows that the stump might actually
heal faster if left alone. If the stump becomes dirty or sticky,
clean it with plain water, after which you dry it by holding a
clean, absorbent cloth around it or fanning it with a piece of
paper.
• Option C: Antibiotic ointment should only be used to treat an
infection, not as prophylaxis.
• Option D: Infants should not be submerged in a tub of water
until the cord falls off and the stump has completely healed.
6. 6. Question
1 point(s)
A newborn weighing 3000 grams and feeding every 4 hours needs 120
calories/kg of body weight every 24 hours for proper growth and
development. How many ounces of 20 cals/oz formula should this
newborn receive at each feeding to meet nutritional needs?
o A. 2 ounces
o B. 3 ounces
o C. 4 ounces
o D. 6 ounces
Answer
Correct Answer: B. 3 ounces
To determine the amount of formula needed, do the following
mathematical calculation. 3 kg x 120 cal/kg per day = 360 calories/day
feeding q 4 hours = 6 feedings per day = 60 calories per feeding: 60
