Obstetrics: Prenatal Care, Normal Pregnancy, and Complications
,1. A pregnant patient presents for her first prenatal visit at 8 weeks'
gestation. Which laboratory test is routinely important during the
initial prenatal evaluation?
A. Serum lipase
B. Blood type and Rh status
C. Troponin level
D. Serum amylase
Answer: B. Blood type and Rh status
Rationale: Determining ABO blood type and Rh status helps identify
patients at risk for Rh alloimmunization and guides prenatal
management.
2. Which hormone is primarily responsible for maintaining the
endometrial lining during early pregnancy?
A. FSH
B. LH
C. Progesterone
D. Prolactin
Answer: C. Progesterone
Rationale: Progesterone maintains the decidualized endometrium
and supports early pregnancy until placental steroid production
becomes established.
3. A pregnant patient has a positive pregnancy test and vaginal
bleeding. The most appropriate initial imaging study is generally:
A. CT abdomen
B. Transvaginal ultrasound
C. Abdominal radiograph
D. MRI with gadolinium
,Answer: B. Transvaginal ultrasound
Rationale: Transvaginal ultrasonography provides high-resolution
evaluation of early pregnancy and can help determine pregnancy
location and viability.
4. Which finding is most characteristic of a normal physiologic
change during pregnancy?
A. Decreased plasma volume
B. Increased systemic vascular resistance
C. Increased plasma volume
D. Decreased cardiac output
Answer: C. Increased plasma volume
Rationale: Plasma volume increases substantially during pregnancy,
producing physiologic hemodilution and contributing to the normal
fall in hemoglobin concentration.
5. The physiologic anemia of pregnancy primarily results from:
A. Hemolysis
B. Decreased erythropoietin production
C. Plasma-volume expansion exceeding red-cell expansion
D. Chronic gastrointestinal bleeding
Answer: C. Plasma-volume expansion exceeding red-cell expansion
Rationale: Plasma volume increases more than red-cell mass,
resulting in dilutional anemia.
6. Which nutrient is particularly important for preventing neural tube
defects?
, A. Vitamin C
B. Folic acid
C. Vitamin D
D. Vitamin K
Answer: B. Folic acid
Rationale: Adequate folate before conception and during early
pregnancy reduces the risk of neural tube defects.
7. A pregnant patient develops nausea and vomiting during the first
trimester. Which intervention is commonly appropriate for mild
symptoms?
A. Immediate hospitalization
B. Dietary modification and small frequent meals
C. Total parenteral nutrition
D. Emergency cesarean delivery
Answer: B. Dietary modification and small frequent meals
Rationale: Mild nausea and vomiting of pregnancy can often be
managed with dietary changes, hydration, and appropriate
antiemetic therapy when necessary.
8. Hyperemesis gravidarum is most strongly suggested by:
A. Mild morning nausea
B. Persistent vomiting with dehydration and weight loss
C. Increased appetite
D. Constipation alone
Answer: B. Persistent vomiting with dehydration and weight loss
