SECTION 1: ANTEPARTUM CARE (Questions 1–45)
Q1. An expectant father asks the nurse, "Which part of the mature sperm contains the male chromosome?"
What is the correct response by the nurse?
A) The head of the sperm
B) The tail of the sperm
C) The midpiece of the sperm
D) The acrosome of the sperm
Answer: A
Rationale: The head of the sperm contains the male chromosomes (23 chromosomes, including the X or Y
chromosome that determines the sex of the fetus). The tail provides motility, the midpiece contains
mitochondria for energy, and the acrosome contains enzymes for penetrating the ovum .

Q2. One of the assessments performed in the birth room is checking the umbilical cord for blood vessels.
Which finding is considered to be within normal limits?
A) Two arteries and one vein
B) One artery and two veins
C) Two arteries and two veins
D) One artery and one vein
Answer: A
Rationale: The normal umbilical cord contains two arteries and one vein. The two umbilical arteries carry
deoxygenated blood from the fetus to the placenta, and the umbilical vein carries oxygenated blood from the
placenta to the fetus. A single umbilical artery (two vessel cord) is associated with congenital anomalies and
requires further evaluation .
Q3. What is the purpose of the ovum's zona pellucida?
A) Prevents multiple sperm from fertilizing the ovum
B) Provides nutrition to the developing embryo
C) Protects the ovum from maternal immune system
D) Facilitates implantation in the uterine wall
Answer: A
Rationale: The zona pellucida is a glycoprotein layer surrounding the ovum that prevents multiple sperm from
fertilizing the ovum (polyspermy). Once one sperm penetrates, the zona pellucida changes to block entry of
additional sperm .

Q4. The nurse is explaining the process of cell division during the preembryonic period to a group of nursing
students. Which statement best describes the characteristics of the morula?
A) Solid ball composed of the first cells formed after fertilization
B) Hollow ball of cells with an inner cell mass
C) A cluster of cells with trophoblast and embryoblast layers
D) A structure containing the amniotic cavity and yolk sac
Answer: A
Rationale: The morula is a solid ball of cells (16-32 cells) formed approximately 3-4 days after fertilization. It is
the stage before the blastocyst forms. The blastocyst (B) is a hollow ball of cells. The trophoblast and
embryoblast (C) form during the blastocyst stage. The amniotic cavity and yolk sac (D) form later during
implantation .
Q5. The upper uterus is the best place for the fertilized ovum to implant due to which anatomical adaptation?
A) Developing baby is best nourished
B) Reduced risk of placenta previa
C) Increased space for fetal growth
D) Enhanced oxygen exchange
Answer: A
Rationale: The upper uterus (fundus) provides the richest blood supply and optimal endometrial thickness for
implantation and nourishment of the developing embryo. Implantation in the lower uterus increases the risk
of placenta previa (B) .
Q6. Some of the embryo's intestines remain within the umbilical cord during the embryonic period because
