ATI RN Maternal Newborn Proctored Exam 2023–2026
Updated Practice Questions, Screenshots, Answers &
Rationales
.
1. A nurse is caring for a client who is 12 weeks pregnant and has a rubella titer
of 1:5. Which of the following actions should the nurse anticipate?
A) Administer rubella vaccine today
B) Repeat rubella titer at 28 weeks
C) Administer rubella vaccine in the postpartum period
D) Isolate the client from other pregnant women
Correct Answer: C
Rationale: A rubella titer <1:10 indicates non-immunity. Rubella vaccine is a live
virus vaccine and is contraindicated during pregnancy. It should be administered
immediately postpartum before discharge, and the client should avoid pregnancy
for 4 weeks.
,2. A nurse is assessing a client at 20 weeks gestation. The fundal height is 18 cm.
Which of the following should the nurse suspect?
A) Multiple gestation (twins)
B) Intrauterine growth restriction (IUGR)
C) Polyhydramnios
D) Normal finding
Correct Answer: B
Rationale: Fundal height in cm should approximately equal weeks of gestation ±2
cm. At 20 weeks, 18 cm is 2 cm below expected, which may indicate intrauterine
growth restriction (IUGR), oligohydramnios, or measurement error. Twins and
polyhydramnios cause larger-than-expected fundal height
,3. A nurse is caring for a client at 16 weeks gestation who has hyperemesis
gravidarum. Which of the following laboratory findings should the nurse report
to the provider?
A) Serum sodium 135 mEq/L
B) Urine specific gravity 1.025
C) Serum potassium 3.0 mEq/L
D) Blood glucose 85 mg/dL
Correct Answer: C
Rationale: Hypokalemia (K <3.5 mEq/L) is a serious finding in hyperemesis
gravidarum due to vomiting and can lead to cardiac arrhythmias. Normal sodium
is 135-145. Urine specific gravity 1.025 is within normal range (1.005-1.030). Blood
glucose 85 mg/dL is normal.
, 4. A nurse is providing discharge teaching to a client with gestational diabetes.
Which of the following statements by the client indicates understanding?
A) "I will need to take insulin injections for the rest of my life."
B) "My blood sugar should be less than 200 mg/dL one hour after meals."
C) "I will have a glucose tolerance test 6-12 weeks after my baby is born."
D) "I can stop checking my blood sugar once I start feeling well."
Correct Answer: C
Rationale: Women with gestational diabetes have a 35-60% risk of developing
type 2 diabetes later in life and should have a glucose tolerance test 6-12 weeks
postpartum. Blood glucose goals are stricter during pregnancy (fasting <95, 1hour
<140). Most women do not require lifelong insulin; diabetes usually resolves after
delivery.
