MULTIPLE CHOICE.
SECTION 1: THE MENSTRUAL CYCLE & FERTILITY (Questions 1–10)
Question 1: Ovulation typically occurs how many days before the next
menstruation?
A) 7 days
B) 10 days
C) 14 days
D) 21 days
Correct answer: C) 14 days
Rationale: Ovulation typically occurs 14 days before the next menstruation. A
mature ovum lives for 12–24 hours after release. Sperm can live up to 5 days
in the female reproductive system .
Question 2: A woman who is trying to conceive asks the nurse how long
sperm can survive in the female reproductive tract. What is the nurse's best
response?
A) 12–24 hours
B) Up to 3 days
, Page 2 of 41
C) Up to 5 days
D) Up to 7 days
Correct answer: C) Up to 5 days
Rationale: Sperm can live up to 5 days in the female reproductive system. The
mature ovum lives 12–24 hours then begins to degenerate .
Question 3: A patient asks the nurse how long after ovulation the egg remains
viable for fertilization. The nurse explains that the egg must be fertilized
within:
A) 6–12 hours
B) 12–24 hours
C) 24–48 hours
D) 48–72 hours
Correct answer: B) 12–24 hours
Rationale: A mature ovum lives 12–24 hours after release and then starts to
degenerate if not fertilized. This is why timing is critical for conception .
Question 4: Progesterone plays which primary role during pregnancy?
A) Increases blood flow to the uterus
B) Softens the cervix
C) Keeps the fetus inside the uterus as a smooth muscle relaxant
D) Develops the breast ductal system
Correct answer: C) Keeps the fetus inside the uterus as a smooth muscle
relaxant
Rationale: Progesterone keeps the fetus inside the uterus by acting as a
smooth muscle relaxant. It keeps the uterus quiet and develops the alveoli for
milk secretion .
Question 5: Estrogen plays which primary role during pregnancy?
A) Keeps the fetus inside the uterus
B) Increases blood flow to the uterus, softens the cervix, and develops the
, Page 3 of 41
breasts
C) Relaxes smooth muscles throughout the body
D) Prevents uterine contractions
Correct answer: B) Increases blood flow to the uterus, softens the cervix,
and develops the breasts
Rationale: Estrogen increases blood flow to the uterus (vasodilation), softens
the cervix, initiates uterine activity, and develops the breasts for lactation .
Question 6: A woman reports a history of four pregnancies, with two term
deliveries and two miscarriages. Using the GTPAL system, this would be
documented as:
A) G4 T2 P0 A2 L2
B) G4 T2 P2 A0 L2
C) G4 T0 P2 A2 L2
D) G2 T2 P0 A2 L0
Correct answer: A) G4 T2 P0 A2 L2
Rationale: GTPAL stands for: G (Gravida—total pregnancies), T (Term—
deliveries at 38+ weeks), P (Preterm—deliveries 20–38 weeks), A (Abortions—
losses under 20 weeks), L (Living children). G=4, T=2, P=0, A=2, L=2 .
Question 7: Naegele's Rule is used to:
A) Determine the mother's blood type
B) Calculate the estimated date of delivery (EDD)
C) Assess fetal heart rate
D) Diagnose gestational diabetes
Correct answer: B) Calculate the estimated date of delivery (EDD)
Rationale: Naegele's Rule is used to determine the expected date of delivery
by taking the first day of the last menstrual period, subtracting 3 months, and
adding 7 days. Alternatively, add 7 days and add 9 months to LMP .

Question 8: A woman's last menstrual period began on June 1. What is her
estimated date of delivery using Naegele's Rule?
A) March 8
B) March 15
C) March 22
D) April 1
Correct answer: A) March 8
Rationale: Using Naegele's Rule: June 1 – 3 months = March 1; March 1 + 7
days = March 8. The EDD would be March 8 .
Question 9: Progesterone is best described as a:
A) Smooth muscle relaxant
B) Smooth muscle stimulant
C) Vasoconstrictor
D) Vasodilator
Correct answer: A) Smooth muscle relaxant
Rationale: Progesterone is a smooth muscle relaxant that keeps the uterus
quiet during pregnancy. It also helps develop the alveoli for milk secretion .
Question 10: Which hormone is detected in pregnancy tests and maintains
the corpus luteum until the placenta becomes functional?
A) Estrogen
B) Progesterone
C) Human chorionic gonadotropin (hCG)
D) Human placental lactogen (hPL)
Correct answer: C) Human chorionic gonadotropin (hCG)
Rationale: hCG maintains the corpus luteum until the placenta becomes
functional. It is the hormone detected in pregnancy tests .
