Maternity/Newborn ATI Study Guide
Amniocentesis ANS: An amniocentesis is used to determine lung maturity, detect
congenital anomalies, and diagnose fetal hemolytic disease.
Cordocentesis ANS: A cordocentesis is used to identify fetal blood type and RBC
when there is a risk of isoimmune hemolytic anemia.
Kleihauer-Betke test ANS: The Kleihauer-Betke test is used to determine the
amount of fetal blood in the maternal circulation when there is a risk of Rh-
isoimmunization.
A positive contraction stress test indicates that further evaluation of the fetus is
necessary. ANS: A biophysical profile will provide further evaluation with a real-
time ultrasound.
Side effects of combined oral contraceptives ANS: The nurse should instruct the
client that depression is a common adverse effect of combined oral
contraceptives. Other common adverse effects of the medication include
amenorrhea, weight gain, headache, nausea, breakthrough bleeding, and breast
tenderness.
A nurse is assessing four newborns. Which of the following findings should the
nurse report to the provider?
a. A newborn who is 26 hr old and has erythema toxicum on his face
b. A newborn who is 32 hr old and has not passed a meconium stool
,c. A newborn who is 12 hr old and has pink-tinged urine
d. A newborn who is 18 hr old and has an axillary temperature of 37.7° C (99.9° F)
ANS: Answer:
d. A newborn who is 18 hr old and has an axillary temperature of 37.7° C (99.9° F)
An axillary temperature greater than 37.5° C (99.5° F) is above the expected
reference range for a newborn and can be an indication of sepsis. Therefore, the
nurse should report this finding to the provider.
Explanation:
Erythema toxicum is a transient rash that can appear anywhere on a newborn's
body during the first 24 to 72 hr following birth and can last up to 3 weeks. This
finding requires no treatment.
A newborn should pass the first meconium stool within the first 24 to 48 hr
following birth. Failure to pass a meconium stool can indicate a bowel obstruction
or congenital disorder. This finding is within the expected reference range.
Pink-tinged urine is an indication of uric acid crystals and is an expected finding
for a newborn during the first week following birth.
side effects of magnesium sulfate ANS: - Hypotension
- Sedation
- Confusion
- N/V
, - Bradycardia
- Pruritis
- Arrhythmias
- Decreased deep tendon reflexes
- Respiratory depression/paralysis
- Drowsiness
- Muscle weakness
- Complete heart block
- When used immediately prior to delivery it can cause fetal hypoxia, asphyxia,
arrhythmias and possible fetal intracranial bleeding
How much folic acid should a pregnant person take daily? ANS: A client who is
pregnant should increase folic acid intake to 600 mcg daily. Folic acid assists with
preventing neural tube birth defects.
Caloric intake for a pregnant person? ANS: A client who is pregnant should
increase caloric intake by 340 cal during the second trimester and by 452 cal
during the third trimester.
How much water should a pregnant patient drink daily? ANS: A client who is
pregnant should consume 3 L of water each day.
Amniocentesis ANS: An amniocentesis is used to determine lung maturity, detect
