Section 1: Antepartum Care - Advanced Clinical Scenarios (Questions
1–30)
1. A nurse is caring for a client at 9 weeks of gestation who presents with severe nausea,
vomiting, and a 7% weight loss from pre-pregnancy weight. Laboratory findings reveal serum
potassium 3.1 mEq/L, sodium 130 mEq/L, and urine ketones 3+. Which of the following
interventions should the nurse anticipate initiating first?
A. Intravenous fluid resuscitation with 0.9% normal saline
B. Administration of intravenous ondansetron
C. Initiation of enteral nutrition via nasogastric tube
D. Thiamine supplementation prior to IV dextrose administration
- detailed answer 100% correct :-D
Rationale: In hyperemesis gravidarum with significant weight loss and electrolyte imbalances,
thiamine (vitamin B1) must be administered BEFORE IV dextrose to prevent Wernicke's
encephalopathy, a potentially irreversible neurological complication. While IV fluids (A), antiemetics
(B), and enteral nutrition (C) may be indicated, thiamine administration is the priority safety
intervention when glucose is being considered.
2. A nurse is assessing a client at 16 weeks of gestation who has a history of two prior
spontaneous abortions. The client reports mild lower abdominal cramping and a small amount
of pink-tinged vaginal discharge. Which of the following diagnostic tests should the nurse
anticipate the provider ordering to evaluate cervical insufficiency?
A. Serum progesterone level
B. Transvaginal cervical length measurement
C. Quantitative beta-hCG level
D. Amniotic fluid volume assessment
- detailed answer 100% correct :-B
Rationale: Transvaginal ultrasound measurement of cervical length is the gold standard for evaluating
cervical insufficiency. A cervical length <25 mm before 24 weeks of gestation is indicative of cervical
insufficiency and increased risk of preterm birth. Serum progesterone (A) is not diagnostic for cervical
insufficiency. Beta-hCG (C) is used to assess pregnancy viability. Amniotic fluid volume (D) is not
specific to cervical insufficiency.
,3. A nurse is providing preconception counseling to a client with type 1 diabetes mellitus. Which
of the following statements indicates the client understands the importance of glycemic control
before pregnancy?
A. "I should aim for an HbA1c of less than 8% before conceiving."
B. "I should aim for an HbA1c of less than 6.5% before conceiving."
C. "I should aim for an HbA1c of less than 7.5% before conceiving."
D. "I should aim for an HbA1c of less than 9% before conceiving."
- detailed answer 100% correct :-B
Rationale: The American Diabetes Association recommends an HbA1c of <6.5% before conception to
reduce the risk of congenital anomalies, which are strongly correlated with hyperglycemia during the
first 8 weeks of gestation. Optimal glycemic control significantly reduces the risk of spontaneous
abortion, fetal anomalies, and other pregnancy complications. An HbA1c of 8% (A), 7.5% (C), or 9% (D)
represents suboptimal control and increased fetal risk.
4. A nurse is assessing a client at 28 weeks of gestation who has gestational diabetes managed
with diet and exercise. The client's fasting blood glucose is 105 mg/dL, 1-hour postprandial
glucose is 155 mg/dL, and 2-hour postprandial glucose is 130 mg/dL. Which of the following
actions should the nurse take?
A. Reinforce dietary instructions and recommend continued monitoring
B. Notify the provider that insulin therapy may be required
C. Recommend increasing exercise to 45 minutes dailyD. Schedule a repeat glucose tolerance test in 2
weeks
- detailed answer 100% correct :-B
Rationale: Gestational diabetes targets are fasting ≤95 mg/dL and 1-hour postprandial ≤140 mg/dL.
The client's fasting (105 mg/dL) and 1-hour postprandial (155 mg/dL) values exceed targets, indicating
poor glycemic control despite diet and exercise. Insulin therapy is indicated when glycemic targets are
consistently exceeded. Reinforcing diet (A) alone is insufficient. Increasing exercise (C) may help but
insulin is indicated. Repeat testing (D) delays necessary intervention.
5. A nurse is caring for a client at 22 weeks of gestation who is diagnosed with an incompetent
cervix. A McDonald cerclage is placed. Which of the following post-procedure instructions
should the nurse include in the teaching plan?
A. "You may resume sexual intercourse after 1 week."
B. "You should report any vaginal bleeding or increased discharge immediately."
C. "You will need to remain on strict bed rest for the remainder of the pregnancy."
D. "You may continue your regular exercise routine."
- detailed answer 100% correct :-B
Rationale: After cerclage placement, clients should report signs of infection, preterm labor, or
membrane rupture including vaginal bleeding, increased discharge, or rupture of membranes. Sexual
intercourse (A) and strenuous activity (D) are typically restricted to prevent cervical irritation and
, infection. Strict bed rest (C) is not universally recommended; activity restrictions vary based on
provider preference and clinical status.
6. A nurse is assessing a client at 32 weeks of gestation who presents with a blood pressure of
158/96 mm Hg, 3+ proteinuria, and right upper quadrant pain. Laboratory results show platelet
count 85,000/mm³ and AST 80 units/L. Which of the following medications should the nurse
anticipate administering first?
A. Magnesium sulfate
B. Labetalol
C. Nifedipine
D. Hydralazine
- detailed answer 100% correct :-A
Rationale: The client is presenting with HELLP syndrome (hemolysis, elevated liver enzymes, low
platelets) with severe preeclampsia. Magnesium sulfate is the first-line medication for seizure
prophylaxis and should be initiated immediately. While labetalol (B), nifedipine (C), and hydralazine (D)
may be used for blood pressure management, seizure prevention with magnesium sulfate is the
priority in this scenario.
7. A nurse is providing teaching to a client at 12 weeks of gestation who has a positive purified
protein derivative (PPD) test. Which of the following statements by the client indicates
understanding of the treatment plan?
A. "I will start isoniazid therapy immediately and continue throughout pregnancy."
B. "I will delay isoniazid therapy until after the first trimester."
C. "I will start isoniazid therapy after the second trimester."
D. "I do not need treatment during pregnancy; I will wait until after delivery."
- detailed answer 100% correct :-B
Rationale: For pregnant clients with a positive PPD (latent tuberculosis) without active disease,
isoniazid (INH) therapy is typically delayed until after the first trimester (after 12 weeks) to minimize
teratogenic risk while still providing treatment during pregnancy. Immediate treatment (A) is not
recommended in the first trimester. Delaying until the second trimester (C) or third trimester is
appropriate. Not treating during pregnancy (D) is incorrect.
8. A nurse is assessing a client at 20 weeks of gestation who has a history of a previous preterm
birth at 32 weeks. The client's cervical length on transvaginal ultrasound is 22 mm. Which of the
following interventions should the nurse anticipate?
A. Progesterone supplementation
B. Cervical cerclage
C. Tocolysis with nifedipine
D. Betamethasone administration
- detailed answer 100% correct :-A
