Q1. During pregnancy, plasma volume increases by approximately:
A) 10-20%
B) 20-30%
C) 40-50%
D) 60-70%
Correct Answer: C
Rationale: Plasma volume increases by approximately 40-50% during pregnancy to
support the needs of the uterus, placenta, and fetus. This increase begins early in
pregnancy and peaks around 24-32 weeks .
Q2. The physiological anemia of pregnancy is caused by:
A) Iron deficiency
B) Folic acid deficiency
C) Disproportionate increase in plasma volume compared to red blood cell mass
D) Decreased erythropoietin production
,Correct Answer: C
Rationale: Physiological anemia of pregnancy occurs because plasma volume increases
by 40-50%, while red blood cell mass increases by only 20-30%. This disproportionate
increase dilutes hemoglobin concentration. This is a normal adaptation, not a
deficiency .
Q3. Nagele's rule is used to calculate:
A) The estimated date of delivery (EDD)
B) The expected fetal weight
C) The gestational age based on fetal heart rate
D) The amniotic fluid volume
Correct Answer: A
Rationale: Nagele's rule calculates EDD using the formula: subtract 3 months from the
first day of LMP, then add 7 days. Example: LMP January 1 → October 8 EDD .
Q4. A woman's estimated date of delivery using Nagele's rule with LMP of June 10
is:
A) March 17
B) March 10
C) April 17
D) May 17
Correct Answer: A
Rationale: LMP June 10 → subtract 3 months → March 10 → add 7 days → March 17.
Nagele's rule assumes a 28-day menstrual cycle .
, Q5. During pregnancy, cardiac output increases by approximately:
A) 10-20%
B) 20-30%
C) 30-50%
D) 50-60%
Correct Answer: C
Rationale: Cardiac output increases by 30-50% during pregnancy, beginning early and
peaking around 24 weeks due to increased stroke volume and heart rate .
Q6. A pregnant woman reports constipation and heartburn. These are likely due
to:
A) Increased progesterone leading to smooth muscle relaxation
B) Increased estrogen leading to increased gastric acid
C) The enlarged uterus compressing the intestines
D) Decreased gastrointestinal motility due to progesterone and pressure from the uterus
Correct Answer: D
Rationale: Progesterone slows gastric emptying and intestinal transit. Combined with
uterine pressure on the stomach and intestines, this causes heartburn and constipation .
Q7. Lightening refers to:
A) The baby dropping into the pelvis
B) The first fetal movements felt by the mother
