1. When assessing a newborn infant's heart rate, which technique is most
important for the nurse to use?
1. Quiet the infant before counting the heart rate.
2. Listen at the apex of the heart.
3. Count the heart rate for at least one full minute.
4. Palpate the umbilical cord: 3. Count the heart rate for at least one full minute.
It is most important for the nurse to count the heart rate for at least one full minute (C) so that
irregularities or murmurs can be detected. (A) is not necessary for the heart rate to be
correctly auscultated. The heart rate can be heard clearly over any point of an infant's
chest, not just (B). Immediately after delivery, (D) will allow the nurse to assess the rate, but
(B) is the most accurate method of obtaining a newborn's heart rate.
2. A client at 25-weeks gestation tells the nurse that she dropped a cooking utensil
last week and her baby jumped in response to the noise. What infor- mation should
the nurse provide?
1. This is a demonstration of the fetus's acoustical reflex.
2. The fetus can respond to sound by 24-weeks gestation.
,3. It is a coincidence the fetus responded at the same time.
4. Report the fetus's behavior to the healthcare provider.: 2. The fetus can respond
to sound by 24-weeks gestation.
At 24-weeks gestation, the fetus's ability to hear loud environment sounds can illicit a
startle response (B). Acoustic stimulations can evoke a fetal heart rate response and fetal
movement, but (A and C) are inaccurate. (D) is not indicated.
3. A client at 28-weeks gestation experiences blunt abdominal trauma. Which
parameter should the nurse assess first for signs of internal hemorrhage?
1. Vaginal bleeding.
2. Complaints of abdominal pain.
3. Changes in fetal heart rate patterns.
4. Alteration in maternal blood pressure: 3. Changes in fetal heart rate patterns.
Hypoperfusion of the fetus may be present before the onset of clinical signs of maternal
compromise or shock in a pregnant woman, so the external fetal monitor tracings should
be assessed first to determine signs of fetal hypoxia due to internal
,bleeding in the mother. (A, B, and D) are not the first findings of internal hemorrhage in the
pregnant client.
4. The nurse assesses a male newborn and determines that he has the follow- ing vital
signs: axillary temperature 95.1 F, heart rate 136 beats/minute and
a respiratory rate 48 breaths/minute. Based on these findings, which action should the
nurse take first?
1. Check the infant's arterial blood gases.
2. Notify the pediatrician of the infant's vital signs.
3. Assess the infant's blood glucose level.
4. Encourage the infant to take the breast or sugar water.: 3. Assess the infant's blood
glucose level.
The nurse should first assess the infant's blood glucose level (C), because the infant is
displaying signs of hypothermia (normal newborn axillary temperature is 96 to 98 F) and
hypoglycemia may occur as glucose is metabolized in an effort to meet cellular energy
demands. The infant's respiratory and heart rates are within normal limits, so (A) is not a
priority. (B and D) would be implemented after information regarding the blood sugar level
has been obtained.
5. A client at 29-weeks gestation with possible placental insufficiency is be- ing
prepared for prenatal testing. Information about which diagnostic study should the
nurse provide information to the client?
1. Amniocentesis.
2. Ultrasonography.
, 3. Chorionic villus sampling.
4. Maternal serum alpha-fetoprotein.: 2. Ultrasonography.
Gestational age, fetal growth, and the status and position of the placenta are monitored by
ultrasound.
6. A multigravida client at 40+ weeks gestation is induced using oxytocin (Pitocin). An
intrauterine pressure catheter (IUPC) is in place when the client's membranes rupture
after 5 hours of active labor. Which finding should require the nurse to implement
further action?
1. Labor has progressed at 1 cm/hr dilation.
2. Intensity of contractions is 130 mm Hg.
3. Contractions are lasting 60 to 80 seconds.
4. Oxytocin is infusing at a rate ot 30 mU/min.: 2. Intensity of contractions is 130
