- BROWARD COLLEGE.
SECTION 1: ANTEPARTUM (PRENATAL) CARE
Question 1
The patient is at 16 weeks gestation. During the assessment, the nurse notes the
patient's fundal height is at the umbilicus. The nurse concludes that the patient is:
A) At 16 weeks gestation
B) At 20 weeks gestation
C) At 20-22 weeks gestation
D) At 24 weeks gestation
Rationale: At 20-22 weeks gestation, the fundus reaches the umbilicus. At 16 weeks, the
fundus is midway between the symphysis pubis and the umbilicus. Fundal height in
centimeters generally corresponds to gestational age in weeks.
Question 2
A pregnant woman at 35 weeks gestation with worsening pre-eclampsia is
admitted to the labor and delivery unit. After 2 hours of IV magnesium sulfate
therapy, which assessment finding indicates magnesium toxicity?
A) Absence of patellar reflexes
B) Serum magnesium level of 6 mEq/L
,C) Urine output of 80 mL in 4 hours
D) Respiratory rate of 18 breaths/minute
Rationale: Magnesium toxicity is characterized by loss of deep tendon reflexes (DTRs) at
serum levels of 7-10 mEq/L. Urine output less than 30 mL/hour may indicate renal
impairment, as magnesium is excreted by the kidneys. A respiratory rate below 12
breaths/min is also a sign of magnesium toxicity.
Question 3
During a prenatal visit, a nurse assesses the client's nutritional status. Which
findings indicate to the nurse that the client is at risk for nutritional deficits?
A) Pre-pregnancy weight: 130 lb (within 10% of ideal body weight)
B) Current hemoglobin level of 10 g/dL
C) Total weight gain: 10 lb at 16 weeks' gestation
D) Blood glucose level 100 mg/dL
Rationale: A hemoglobin level of 10 g/dL in pregnancy indicates anemia. The normal
hemoglobin in pregnancy is 11-12.5 g/dL due to hemodilution. Iron deficiency is the
most common cause.
Question 4
A nurse is counseling a client who is Rh-negative about Rh isoimmunization.
Which statement indicates the client understands the teaching?
A) "The injection is given to prevent my body from producing antibodies against
the baby."
B) "The injection is given to treat my baby's anemia."
C) "The injection is given to prevent me from becoming anemic."
D) "The injection is given to treat my baby's jaundice."
,Rationale: RhoGAM (Rh immunoglobulin) is given to Rh-negative mothers to prevent
maternal antibody formation against Rh-positive fetal red blood cells. It is administered
at 28 weeks and within 72 hours of delivery.
Question 5
A patient is scheduled for a non-stress test (NST) at 38 weeks gestation. The nurse
should instruct the patient to:
A) Take a sedative before the test
B) Eat a meal before the test
C) Empty the bladder before the test
D) Lie in a supine position during the test
Rationale: A non-stress test (NST) evaluates fetal well-being by monitoring fetal heart
rate (FHR) accelerations. Patients should eat a meal before the test to stimulate fetal
activity. Supine position should be avoided; left lateral position is preferred.
Question 6
A nurse is assessing a client at 28 weeks gestation. The fundal height measurement
is 24 cm. Which nursing action is most appropriate?
A) Document the findings as normal
B) Notify the provider
C) Prepare for an ultrasound
D) Instruct the client to increase fluid intake
Rationale: Fundal height should be within 2 cm of gestational age. At 28 weeks, the
fundal height should be 26-30 cm. A measurement of 24 cm is below normal and may
indicate intrauterine growth restriction (IUGR) or oligohydramnios. The provider should
be notified.
, Question 7
A patient at 12 weeks gestation is experiencing nausea and vomiting. Which
teaching is most appropriate?
A) Eat small, frequent meals throughout the day
B) Avoid eating anything when nauseated
C) Drink large amounts of fluid with meals
D) Lie down immediately after eating
Rationale: Small, frequent meals help prevent nausea by maintaining blood glucose
levels and avoiding an empty stomach. Eating dry crackers before rising in the morning
can also help. Drinking fluids with meals can distend the stomach and worsen nausea.
Question 8
Which of the following is a normal physiologic change during pregnancy?
A) Increased cardiac output
B) Decreased respiratory rate
C) Decreased blood volume
D) Decreased glomerular filtration rate
Rationale: Cardiac output increases by 30-50% during pregnancy. Respiratory rate
increases slightly, blood volume increases by 40-50%, and glomerular filtration rate
increases. The enlarged uterus can cause supine hypotensive syndrome when the
patient is in the supine position.
Question 9
A nurse is providing teaching to a pregnant client about warning signs during
pregnancy. Which of the following should be reported to the healthcare provider?
A) Headache with visual changes
B) Breast tenderness
