overweight: 7–11.5 kg; obese: 5–9 kg.
2. Which maternal cardiac change is characteristic of normal
pregnancy?
A) Decreased heart rate
B) Increased systemic vascular resistance
C) Increased stroke volume
D) Decreased cardiac output

Rationale: Stroke volume increases 30–50% by mid-
pregnancy. Heart rate increases 15–20 bpm; SVR decreases;
CO increases 30–50%.
3. A 32-year-old G2P1 at 20 weeks has a fundal height of

A) 12–16 weeks
B) 20–24 weeks
C) 28–32 weeks
