ATI Capstone Maternal Newborn Assessment

Answers & Detailed Rationales Bundle
Question 1
A nurse is assessing a client who is at 34 weeks of gestation and has a
prescription for a nonstress test (NST). Which of the only
configurations confirms a reactive nonstress test?
A. Fetal heart rate accelerations of less than 15 beats/min lasting 10
seconds.
,B. Absence of fetal heart rate accelerations during a 40-minute testing
window.
C. Two or more fetal heart rate accelerations of at least 15 beats/min
lasting at least 15 seconds within a 20-minute period.
D. Persistent late decelerations coinciding with spontaneous uterine
contractions.
VERIFIED ANSWER: C. Two or more fetal heart rate
accelerations of at least 15 beats/min lasting at least 15 seconds
within a 20-minute period.
EXPLANATION: A reactive nonstress test is a reassuring sign of
fetal well-being. It is defined by the presence of two or more fetal
heart rate accelerations of at least 15 beats per minute (bpm) above
the baseline, lasting for at least 15 seconds, within a 20-minute
tracking window. If the fetus is less than 32 weeks of gestation,
accelerations of 10 bpm lasting 10 seconds are considered reactive.
Question 2
A nurse is caring for a client who is at 32 weeks of gestation and is
receiving magnesium sulfate via continuous IV infusion for
preeclampsia. Which of the following findings should the nurse report
to the provider immediately?
A. Deep tendon reflexes of 2+ bilaterally.
, B. Urine output of 20 mL/hr over the last 2 hours.
C. Respiratory rate of 14 breaths per minute.
D. Client reports feeling flushed and warm.
VERIFIED ANSWER: B. Urine output of 20 mL/hr over the last 2
hours.
EXPLANATION: Magnesium sulfate is cleared completely by the
kidneys. A decrease in urine output below 30 mL/hr can lead to
toxic accumulation of magnesium. Signs of magnesium toxicity
include a loss of deep tendon reflexes, respiratory depression (under
12/min), altered mental status, and cardiac arrest. Feeling flushed
or warm is a common, non-toxic side effect during initial infusion.
Question 3
A nurse in the labor and delivery unit is caring for a client who is in
active labor. The nurse notes late decelerations on the fetal heart rate
monitor strip. Which of the following actions should the nurse take
first?
A. Administer oxygen at 2 L/min via nasal cannula.
B. Increase the rate of the maintenance intravenous fluid.
C. Assist the client into a lateral decubitus position.
D. Prepare the client for an immediate amniotomy.
