Questions & Answers
Section 1: Antepartum Care & Complications (Questions 1–30)
1. A nurse is calculating the estimated date of birth for a client whose last
menstrual period began on March 5. Using Naegele's rule, which date should the
nurse calculate?
A) December 5
B) December 12
C) December 19
D) November 12
Rationale: Naegele's rule: subtract 3 months from the first day of the LMP and
add 7 days. March 5 minus 3 months = December 5; December 5 + 7 days =
December 12. This is the standard method for calculating the estimated date of
delivery .
2. A nurse is teaching a client at 10 weeks gestation about expected
physiological changes. Which finding should the nurse include as a normal
cardiovascular adaptation?
A) Decreased blood volume
B) Increased heart rate of 10–15 beats/min
C) Decreased cardiac output
D) Increased blood pressure in the first trimester
Rationale: Heart rate increases 10–15 bpm during pregnancy due to increased
metabolic demands. Blood volume increases 40–50%, cardiac output increases,
and BP typically decreases slightly in the second trimester .
3. A client at 28 weeks gestation reports heartburn. Which instruction should
the nurse provide?
