 NSG 6021 Reproductive Questions and Answers Updates RATED A+

1.A couple who have three daughters would like to add a son to their family, and
they have recently learned that the woman is pregnant. Which of the following
phenomena would most likely be associated with the woman's eventual delivery of
a healthy son?
A)The production of dihydrotestosterone (DHT) by the embryo and
DHT's differentiation into testosterone
B)Development of testes under the influence of the X chromosome
C)Suppression of female reproductive structures by anti-Müllerian
hormone (AMH)
D)Atrophy of the Wolffian ducts during embryonic development
Feedback: AMH suppresses the development of female genital structures and is a
normal aspect of normal sex differentiation. Testosterone is a precursor to DHT
rather than vice versa, and testes develop under the influence of the Y
chromosome. The Wolffian ducts are a component of male sex differentiation
2.The nurse knows that if which of the following hormones listed below are not
available during embryonic development, a male embryo with an XY
chromosomal pattern may develop female external genitalia? Select all that
apply. A)Anti-Müllerian hormone (AMH)
B)Testosterone
C)Dihydrotestosterone (DHT)
D)Acrosome
E)Follicle-stimulating hormone (FSH)
Feedback: In the absence of testosterone (and DHT), a male embryo with an XY
chromosomal pattern develops female external genitalia. AMH suppresses the
Müllerian ducts and prevents development of the uterus and fallopian tubes in
the male. Acrosome is the outside of the anterior two thirds of the head of a
sperm. For spermatogenesis to occur, FSH binds to specific receptors in Sertoli
cells.
3.A 68-year-old male has visited his family physician because the size of his
scrotum has increased exponentially in recent months. He has subsequently been
diagnosed with an inguinal hernia. Which of the following statements best
captures the nature of his health problem?
A) Part of his intestine and parietal peritoneum are protruding through
the inguinal opening.
B)Rupture of the tunica vaginalis has allowed a part of his small bowel to
protrude into the intrascrotal space.
C)Incomplete closure of the inguinal opening during his development has
contributed to testicular hypertrophy and hyperplasia.
D)Occlusion of the efferent ductules and epididymis causes massive dilation of
the testes.
Feedback: An inguinal hernia is the protrusion of intestine and peritoneum into the
scrotum through an incompletely sealed inguinal opening. The tunica vaginalis,
occlusion of the duct system, nor testicular hypertrophy and hyperplasia contribute
to the etiology.
