1. A neonate is born by primary cesarean section at 36 weeks' gestation. The
temperature in the birthing room is 70°F (21.1°C). To prevent heat loss from
convection, which action should the nurse take?
1. Dry the neonate quickly after birth.
2. Keep the neonate away from air conditioning vents.
3. Place the neonate away from outside windows.
4. Prewarm the bed.
3. 2. The neonate should be kept away from drafts, such as from air conditioning
vents, which may cause heat loss by convection. Evaporation is one of the most
common
mechanisms by which the neonate will lose heat, such as when the moisture on the
newly born neonate's body is converted to vapor. Radiation is heat loss between
solid
objects that are not in contact with one another such as walls and windows.
Conduction
is when heat is transferred between solid objects in contact with one another, such
as
when a neonate comes in contact with a cold mattress or scale.
2. Prewarm the bed.
The primary health care provider prescribes ampicillin 100 mg/kg/dose for a
newly
admitted neonate. The neonate weighs 1,350 g. How many milligrams should
the nurse
administer?
_______________ mg.
4. 135 mg
The recommended dose of ampicillin for a neonate is 100 mg/kg/dose. First,
determine the neonate's weight in kilograms, and then multiply the kilograms by 100
, Page 2 of 37
mg.
The nurse should use this formula:
3. A primiparous woman has recently given birth to a term infant. Priority
teaching
for the client includes information on:
1. Sudden Infant Death Syndrome (SIDS).
2. Breast-feeding.
3. Infant bathing.
4. Infant sleep-wake cycles.
1. 2. Breast-fed infants should eat within the first hour of life and approximately
every 2 to 3 hours. Successful breast-feeding will likely require sustained support,
encouragement, and instruction from the nurse. Information on SIDS, infant bathing,
and
sleep-wake cycles are also important topics for the new parent, but can be done at
any
time prior to discharge.
4. A newborn who is 20 hours old has a respiratory rate of 66, is grunting when
exhaling, and has occasional nasal flaring. The newborn's temperature is 98°F
(36.6°C);
he is breathing room air and is pink with acrocyanosis. The mother had
membranes that
were ruptured 26 hours before birth. Based on these data, the nurse should
include
which of the following in the management of the infant's care?
1. Continue recording vital signs, voiding, stooling, and eating patterns every 4
hours.
2. Place a pulse oximeter and contact the primary health care provider for a
prescription to draw blood cultures.
3. Arrange a transfer to the neonatal intensive care unit with diagnosis of
possible
sepsis.
4. Draw a complete blood count (CBC) with differential and feed the infant.
2. 2. The concern with this infant is sepsis based on prolonged rupture of
membranes before birth. Blood cultures would provide an accurate diagnosis of
, Page 3 of 37
sepsis,
but will take 48 hours from the time drawn. Frequent monitoring of infant vital signs,
looking for changes, and maintaining contact with the parents is also part of care
management while awaiting culture results. Continuing with vital signs, voiding,
stooling, and eating every 4 hours is the standard of care for a normal newborn, but
a
respiratory rate greater than 60, grunting, and occasional flaring are not normal.
Although not normal, the need for the intensive care unit is not warranted as
newborns
with sepsis can be treated with antibiotics at the maternal bedside. The CBC does
not
establish the diagnosis of sepsis but the changes in the WBC levels can identify an
infant
at risk. Many experts suggest that waiting until an infant is 6 to 12 hours old to draw
a
CBC will give the most accurate results.
5. A neonate born at 30 weeks' gestation and weighing 2,000 g is admitted to
the
neonatal intensive care unit. What nursing measure will decrease insensible
water loss
in a neonate?
1. Bathing the baby as soon after birth as possible.
2. Use of eye patches with phototherapy.
3. Use of humidity in the incubator.
4. Use of a radiant warmer.
5. 3. Adding humidity to the incubator adds moisture to the ambient air, which helps
to decrease the insensible water loss. Bathing and the use of eye patches has no
impact
on insensible water loss. The use of a radiant warmer will increase the insensible
water
loss by drawing moisture out of the skin.
6. A septic preterm neonate's IV was removed due to infiltration. While
restarting
the IV, the nurse should carefully assess the neonate for:
, Page 4 of 37
1. Fever.
2. Hyperkalemia.
3. Hypoglycemia.
4. Tachycardia.
6. 3. Neonates that are septic use glucose at an increased rate. During the time the
IV
is not infusing, the neonate is using the limited glucose stores available to a preterm
neonate and may deplete them. Hypoglycemia is too little glucose in the blood;
without
the constant infusion of IV glucose, hypoglycemia will result. Fevers and
hyperkalemia
are not related to glucose levels. Tachycardia is the result of untreated
hypoglycemia.
7. The nurse makes a home visit to a 3-day-old full-term neonate who weighed
3,912 g (8 lb, 10 oz) at birth. Today the neonate, who is being bottle-fed, weighs
3,572
g (7 lb, 14 oz). Which of the following instructions should the nurse give to the
mother?
1. Continue feeding every 3 to 4 hours since the weight loss is normal.
2. Contact the primary health care provider if the weight loss continues over
the
next few days.
3. Switch to a soy-based formula because the current one seems inadequate.
4. Change to a higher-calorie formula to prevent further weight loss.
7. 1. This 3-day-old neonate's weight loss falls within a normal range, and therefore
no action is needed at this time. Full-term neonates tend to lose 5% to 10% of their
birth
weight during the first few days after birth, most likely because of minimal nutritional
intake. With bottle-feeding, the neonate's intake varies from one feeding to another.
Additionally, the neonate experiences a loss of extracellular fluid. Typically, neonates
regain any weight loss by 7 to 10 days of life. If the weight loss continues after that
time,
the primary health care provider should be called.
