1. 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.
X-bearing sperm
b.
The tail of the sperm
c.
The head of the sperm
d.
The middle portion of the sperm - correct answer
☑️☑️ANS: C
The head of the sperm contains the male chromosomes
that will join the chromosomes of the ovum. If an X-
bearing sperm fertilizes the ovum, the baby will be
female. The tail of the sperm helps propel the sperm
toward the ovum. The middle portion of the sperm
supplies energy for the tail's whip-like action.

2. 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.
One artery and one vein
b.
Two veins and one artery
c.
Two arteries and one vein
d.
Two arteries and two veins - correct answer ☑️☑️ANS: C
The umbilical cord contains two arteries and one vein to
transport blood between the fetus and the placenta. Any
option other than two arteries and one vein is considered
abnormal and requires further assessment. Two veins and
one artery is abnormal and may indicate an anomaly. Two
arteries instead is a normal finding; this infant would
require further assessment for anomalies due to the
finding of two veins.

3. What is the purpose of the ovum's zona pellucida?
a.
Prevents multiple sperm from fertilizing the ovum
b.
Stimulates the ovum to begin mitotic cell division
c.
Allows the 46 chromosomes from each gamete to merge
d.
Makes a pathway for more than one sperm to reach the
ovum - correct answer ☑️☑️ANS: A
Fertilization causes the zona pellucida to change its
chemical composition so that multiple sperm cannot
fertilize the ovum. Mitotic cell division begins when the
nuclei of the sperm and ovum unite. Each gamete (sperm
and ovum) has only 23 chromosomes; there will be 46
chromosomes when they merge. Once sperm has entered
the ovum, the zona pellucida changes to prevent other
sperm from entering.
