PRACTICE QUESTIONS & RATIONALES
DOCUMENT OVERVIEW
• This resource contains 200 comprehensive practice questions designed to
replicate the NGN format of the ATI RN Maternal Newborn OB Proctored Exam,
enabling you to assess readiness across all major content areas and identify
knowledge gaps before the actual exam.
• Study effectively by working through questions section by section, reviewing
detailed rationales for all answers (not just incorrect ones), and timing yourself to
build exam-paced endurance for the actual testing environment.
QUESTION 1
A 28-year-old primigravida at 32 weeks gestation presents to the prenatal
clinic with complaints of swelling in her feet and ankles that worsens
throughout the day. Her blood pressure is 138/88 mmHg, and urinalysis shows
1+ proteinuria. Which nursing assessment finding would be most concerning
for the development of preeclampsia?
A) Mild ankle edema that resolves with rest
B) Blood pressure elevation in the afternoon only
C) Weight gain of 1 lb per week consistently
D) Presence of proteinuria with hyperreflexia
E) Occasional mild headache in the evening
D) Presence of proteinuria with hyperreflexia
Rationale: The combination of proteinuria and hyperreflexia suggests the
development of preeclampsia, which is a serious hypertensive disorder of
,pregnancy. While mild edema and occasional blood pressure elevation can occur in
normal pregnancy, the triad of hypertension, proteinuria, and hyperreflexia
indicates a pathological process requiring immediate intervention. Hyperreflexia is
a sign of central nervous system irritability and increased risk for progression to
eclampsia.
QUESTION 2
A 35-year-old multigravida at 28 weeks gestation is diagnosed with
gestational diabetes mellitus. She asks the nurse why frequent blood glucose
monitoring is necessary. Which response by the nurse is most accurate?
A) To determine if insulin therapy will be needed immediately
B) To identify maternal hyperglycemia that can lead to fetal macrosomia and birth
complications
C) To confirm the diagnosis and adjust the diet plan weekly
D) To prevent the development of type 2 diabetes in the mother after pregnancy
E) To monitor kidney function and prevent diabetic nephropathy
B) To identify maternal hyperglycemia that can lead to fetal macrosomia
and birth complications
Rationale: Frequent blood glucose monitoring in gestational diabetes mellitus
allows early detection of maternal hyperglycemia, which crosses the placenta and
stimulates fetal pancreatic insulin production. This results in fetal hyperinsulinemia,
leading to increased fat deposition and fetal macrosomia. Macrosomia increases
risks for shoulder dystocia, birth trauma, and neonatal hypoglycemia. While insulin
may eventually be needed and there is increased risk for type 2 diabetes
postpartum, the primary goal of monitoring is to prevent hyperglycemia-related
fetal complications.
QUESTION 3
,During a routine prenatal visit at 20 weeks gestation, a client reports a
history of recurrent spontaneous abortions in her first trimester. The nurse
should assess for which additional risk factor that would warrant further
evaluation?
A) Maternal age over 30 years
B) Uterine abnormalities or cervical incompetence
C) Multiparity with previous full-term deliveries
D) Regular exercise and physical activity
E) History of seasonal allergies
B) Uterine abnormalities or cervical incompetence
Rationale: Recurrent first-trimester losses warrant investigation for structural
abnormalities of the uterus (such as septate uterus, unicornuate uterus) or cervical
incompetence, which are significant risk factors for spontaneous abortion. Cervical
incompetence may present as painless dilation during the second trimester and is
associated with previous pregnancy trauma. These are modifiable or manageable
conditions that require specific interventions. While advanced maternal age is a risk
factor, it is not as actionable as structural abnormalities. Multiparity with successful
outcomes and regular exercise are protective factors, not risk factors.
QUESTION 4
A 32-year-old woman at 36 weeks gestation presents to the labor unit with
vaginal bleeding. Fetal heart rate is 145 beats per minute and reactive.
Contractions are occurring every 3-4 minutes lasting 45 seconds. The client
denies abdominal pain. Which nursing action is the priority?
A) Perform a digital cervical examination to determine dilation
B) Obtain an ultrasound to determine placental location
C) Encourage ambulation to promote labor progression
D) Administer oxygen at 2 liters per minute
, E) Prepare the client for emergency cesarean delivery
B) Obtain an ultrasound to determine placental location
Rationale: Painless vaginal bleeding at term is highly suspicious for placenta
previa. Digital cervical examination is contraindicated before placental location is
confirmed, as manipulation could precipitate massive hemorrhage if previa is
present. Ultrasound is the definitive diagnostic tool to visualize placental location.
The reassuring fetal heart rate and contractions do not eliminate the need for
accurate diagnosis first. Once placental location is confirmed, appropriate delivery
planning can proceed.
QUESTION 5
A 24-year-old primigravida at 8 weeks gestation is prescribed metformin for
gestational diabetes management. She asks about the safety of this
medication for her developing fetus. What is the most appropriate nursing
response?
A) Metformin is contraindicated in pregnancy and should be discontinued
immediately
B) Metformin is safe in pregnancy and preferred over insulin for gestational
diabetes
C) Metformin crosses the placenta and is known to cause fetal abnormalities
D) Metformin may be used but requires weekly ultrasounds to monitor fetal
development
E) Metformin should only be used if dietary modifications have failed
B) Metformin is safe in pregnancy and preferred over insulin for
gestational diabetes
Rationale: Metformin is classified as a Category B medication and is safe to use
during pregnancy. Research supports its use as first-line therapy for gestational
diabetes management and is often preferred because it does not cause
hypoglycemia and has a lower incidence of neonatal hypoglycemia compared to
