1By the third trimester of pregnancy, maternal blood volume has increased above pre-pregnancy levels by approximately what amount?

A.10-20%

B.25-35%

C.40-50%

D.70-80%

Explanation: Maternal blood volume expands by approximately 40-50% above baseline by 32-34 weeks gestation, peaking around that time. This expansion supports placental perfusion, accommodates expected blood loss at delivery, and protects against orthostatic changes. Plasma volume increases more than red cell mass, producing the physiologic anemia of pregnancy.

2An antepartum nurse reviews the CBC of a healthy patient at 30 weeks gestation. Which finding is consistent with normal physiologic anemia of pregnancy?

A.Hemoglobin 13.5 g/dL, hematocrit 41%

B.Hemoglobin 11.0 g/dL, hematocrit 33%

C.Hemoglobin 8.5 g/dL, hematocrit 26%

D.Hemoglobin 15.0 g/dL, hematocrit 45%

Explanation: Physiologic (dilutional) anemia of pregnancy occurs because plasma volume expands proportionally more than red cell mass. CDC and ACOG define anemia in the second/third trimester as Hgb <10.5 g/dL or Hct <33%, so a Hgb of 11.0 g/dL with Hct 33% reflects expected hemodilution rather than pathology.

3Which respiratory change is expected during a normal pregnancy?

A.Decreased tidal volume and increased functional residual capacity

B.Increased tidal volume and decreased functional residual capacity

C.Decreased respiratory rate and decreased minute ventilation

D.Unchanged tidal volume with increased residual volume

Explanation: Pregnancy is characterized by a 30-40% increase in tidal volume, driven largely by progesterone, which produces a chronic compensated respiratory alkalosis. The enlarging uterus elevates the diaphragm, decreasing functional residual capacity by about 20%. Respiratory rate remains essentially unchanged.

4When auscultating heart sounds in a healthy pregnant patient at 28 weeks gestation, the nurse most likely will hear

A.a loud pansystolic murmur radiating to the axilla

B.a soft systolic ejection murmur at the left sternal border

C.an early diastolic decrescendo murmur

D.a fixed split S2 unaffected by respiration

Explanation: A soft systolic ejection murmur is heard in roughly 90% of pregnant women due to increased blood flow across normal cardiac valves. Diastolic murmurs, holosystolic murmurs, and loud or radiating murmurs are NOT physiologic and require cardiology evaluation.

5A patient at 26 weeks gestation reports nausea, hand tingling, and dizziness when lying flat for an ultrasound. The nurse's first action should be to

A.administer supplemental oxygen at 2 L/min via nasal cannula

B.place a wedge under the right hip to displace the uterus to the left

C.elevate both legs to increase venous return

D.obtain a 12-lead ECG

Explanation: These symptoms reflect supine hypotensive (aortocaval compression) syndrome: the gravid uterus compresses the inferior vena cava when supine, reducing venous return and cardiac output. Lateral uterine displacement (left lateral tilt or wedge under the right hip) restores venous return and is the first intervention.

6Which arterial blood gas pattern reflects the expected acid-base status of a healthy pregnant patient at 32 weeks?

A.pH 7.30, PaCO2 50, HCO3 24

B.pH 7.44, PaCO2 30, HCO3 20

C.pH 7.50, PaCO2 28, HCO3 26

D.pH 7.35, PaCO2 40, HCO3 24

Explanation: Pregnancy produces a chronic compensated respiratory alkalosis: progesterone-driven hyperventilation drops PaCO2 to roughly 28-32 mm Hg, and the kidneys compensate by excreting bicarbonate (HCO3 around 18-22 mEq/L), keeping pH only slightly alkalotic (about 7.40-7.45).

7Glomerular filtration rate (GFR) during normal pregnancy

A.decreases by approximately 25% due to compression of renal vessels

B.increases by approximately 50% beginning early in the first trimester

C.remains unchanged from pre-pregnancy values

D.increases only in the third trimester after the placenta matures

Explanation: GFR rises by about 50% by the end of the first trimester and remains elevated throughout pregnancy. This explains the lower normal serum creatinine in pregnancy (typically <0.8 mg/dL) and the appearance of mild glycosuria/proteinuria. Values that would be normal in a non-pregnant adult may indicate renal compromise during pregnancy.

8A nurse is reviewing prenatal labs for an antepartum admission. Which result requires the most immediate follow-up?

A.Trace urine glucose

B.Platelet count of 240,000/microliter

C.Indirect Coombs positive in an Rh-negative patient

D.TSH 2.5 mIU/L

Explanation: A positive indirect Coombs in an Rh-negative patient indicates anti-D antibodies (alloimmunization), which can cause hemolytic disease of the fetus and newborn. This requires titer follow-up, MCA Doppler surveillance, and maternal-fetal medicine involvement. RhoGAM is no longer protective once antibodies are present.

9A patient at 22 weeks gestation discloses past intimate partner violence and asks the nurse about safety planning. The nurse's most appropriate initial response is to

A.tell the patient that documentation will be entered into a public record

B.thank the patient for sharing, ensure privacy, and offer screening tools and referrals

C.advise the patient that nothing can be done unless violence has occurred during pregnancy

D.contact law enforcement on the patient's behalf without consent

Explanation: Trauma-informed care begins with acknowledging the disclosure, creating a private and nonjudgmental environment, and offering validated screening (e.g., HITS, AAS) along with referrals to hotlines, advocacy services, and safety planning. Pregnancy is a high-risk period for escalation, so the conversation is therapeutic and central to antepartum care.

10The Edinburgh Postnatal Depression Scale (EPDS) is used during the antepartum period because

A.it can only be used after delivery

B.it is validated for use during pregnancy and the postpartum year

C.it screens specifically for psychotic symptoms

D.it replaces the need for clinical interview

Explanation: The EPDS is a 10-item validated tool for perinatal depression screening across pregnancy and the first postpartum year. ACOG and AWHONN recommend at least one screen during pregnancy. A score of 10 or greater warrants further assessment, and item 10 (self-harm) is reviewed regardless of total score.

About the RNC-IAP Exam

Specialty certification for registered nurses providing inpatient antepartum care. The RNC-IAP exam launched February 2022 and validates expertise in maternal/fetal physiology and assessment, obstetric complications, medical complications in pregnancy, and antepartum pharmacology — the core knowledge base for nurses caring for hospitalized antepartum patients on MFM and high-risk OB units.

Frequently Asked Questions

When did the RNC-IAP exam launch?

NCC launched the RNC-IAP (Inpatient Antepartum Nursing) certification in February 2022. It is the first NCCA-accredited certification specifically for nurses caring for hospitalized antepartum patients, separate from the more general RNC-OB credential. NCCA accreditation extends through December 31, 2028.

What are the RNC-IAP eligibility requirements?

To sit for the RNC-IAP exam, you need: 1) A current, active, unencumbered RN license in the US or Canada. 2) A minimum of 2 years of specialty experience in inpatient antepartum nursing. There is no additional CE requirement to test, but maintenance requires CE every 3 years.

What is the most heavily weighted RNC-IAP domain?

Obstetric Complications carries the largest weight at 31%. This domain includes hypertensive disorders (preeclampsia, HELLP, eclampsia), diabetes and DKA, placental abnormalities (previa, abruption, accreta), preterm labor management, multiple gestation complications, and obstetric emergencies including cord prolapse and amniotic fluid embolism.

How is RNC-IAP different from RNC-OB?

RNC-OB (Inpatient Obstetric Nursing) covers labor and delivery and immediate postpartum care. RNC-IAP focuses specifically on the antepartum hospitalized patient — high-risk pregnancies admitted for monitoring or management of complications before labor. Many MFM and high-risk OB units now hire and credential RNs against RNC-IAP rather than RNC-OB.

How should I study for the RNC-IAP exam?

Plan for 60-100 hours of study over 8-12 weeks. Focus heaviest on Obstetric Complications (31%) and Medical Complications in Pregnancy (27%) — together they are 58% of the exam. Use the NCC RNC-IAP candidate guide as your blueprint and complete at least 100 practice questions, aiming for 80%+ consistency before scheduling.
