1. CH. 5 The perinatal nurse explains to a new nurse that a female fetus has a
developed ovary by
A. 8 weeks
B. 10 weeks
C. 12 weeks
D. 16 weeks - ANSWER B
2. A nurse is teaching a patient how to track her menstrual cycle. What day does
the nurse tell the patient to label as day 1?
A. First day after the menstrual cycle
B. First day of the menstrual cycle
C. Last day before the menstrual cycle
D. Last day of the menstrual cycle - ANSWER: B
Day 1 of the menstrual cycle begins with the onset of bleeding.
3. A woman is in the family planning clinic to learn about her cycle and the best
times to get pregnant. What information should the nurse plan to teach her?
A. An ovum can be fertilized for 12 to 24 hours after ovulation.
B. Pregnancy can only occur during the follicular phase.
C. There are no physiological signs that demonstrate ovulation.
D. You can't easily get pregnant if your cycles are irregular. -
ANSWER: A
An ovum is capable of being fertilized by a sperm cell for approximately 12 to 24
hours after ovulation. Pregnancy occurs during ovulation, which marks the end of
the follicular phase and the beginning of the luteal phase. There are physiological
signs of ovulation, such as changes in cervical mucus and body temperature.
Women with irregular cycles can get pregnant.
,4. In providing anticipatory guidance to a 12-year-old female who has developed
breast buds, what information should the nurse provide?
A. Breast self-exam is now important.
B. First period will occur in 6 months.
C. Growth of pubic hair will occur next.
D. Maximum height has been obtained. - ANSWER: C
The larche (breast budding) is followed by the growth of pubic hair. Breast self-
exam is not vital until the breasts have developed, and then self-exam is taught as
a component of breast awareness. Menarche, the first period, usually occurs 1
year after peak height velocity. It is not possible to state if maximum height has
been obtained. Thelarche starts on average at age 9.8 years and is complete on
average at age 14.6 years. The growth spurt starts on average at age 10 years and
is complete on average by age 11
5. A family practice nurse is providing anticipatory guidance to an 11-year-old
boy. What information about puberty should the nurse plan to include?
A. Boys start puberty about 2 years earlier than girls.
B. Circulating estrogen may cause breast enlargement.
C. Testosterone production is the last stage of puberty.
D. The first sign of puberty is testicular enlargement. - ANSWER: D
Testosterone secretion causes testicular enlargement, which is the first sign of
pubertal changes in males. Girls start puberty about 2 years earlier than boys.
Testosterone production causes the first signs of puberty, so saying that this is a
late occurrence is incorrect. Breast enlargement usually does not occur in males
despite the presence of circulating estrogen.
6. A 14-year-old girl asks the school nurse why her periods are so irregular.
What is the best response by the nurse?
A. "All young girls have irregular periods
B. "Don't worry; this is totally normal."
C. "Estrogen levels are still pretty low."
D. "You should be seen by your physician." - ANSWER: C
,As a girl begins menstruating, estrogen levels are usually insufficient to stimulate
ovulation, and the menstrual periods are generally unpredictable and irregular. As
the ovaries mature, regular ovulation and menses are established. Telling the
student that all young girls have irregular periods and that her complaint is normal
are both poor choices, because they do not give the girl adequate information. She
does not need to be seen by her physician for this complaint.
7. A nurse reads in a female patient's chart that she is Tanner stage V. What can
the nurse conclude about this patient?
A. Beginning puberty
B. Midpoint of puberty
C. Sexually immature
D. Sexually mature - ANSWER: D
Guidelines of secondary sexual characteristic development, termed Tanner stages,
measure the predictable stages of pubertal body changes in both genders. A
female in stage V (the last stage) would be sexually mature.
8. A nurse is teaching a class about gender maturation. What information is most
accurate?
A. Gender is determined by 8 weeks of gestation, when sex organs are
visible.
B. Gender maturity is not fully complete until old age.
C. It is a lengthy process that spans from the embryonic stage through
puberty.
D. The process begins and ends during fetal development. - ANSWER:
C
Gender maturation is a lengthy process that begins during embryonic
development and is completed during late adolescence, at which time full
maturity is achieved. The other statements are not correct.
9. A mother brings her 9-year-old daughter to the family practice clinic. She is
worried because the daughter already has definite breast buds and is asking to
wear a bra. What response by the nurse is best?
, A. "At what age did you develop breast buds or start menstruating?"
B. "Does anyone in your family have a history of precocious
development?"
C. "The average age for breast budding is 9.8 years, so she is normal."
D. "This is too early for breast buds; she may need endocrine studies." -
ANSWER: C
The average age that breast budding begins is 9.8 years, so this child is normal.
The other responses are not relevant for this situation.
10.The nurse teaching a course in human reproduction informs the class that
which reproductive structure is the first to form in the embryo?
A. Gonad
B. Mesoderm
C. Mesonephric duct
D. Oocyte - ANSWER: A
The first reproductive structure formed in the embryo is a gonad. This early
reproductive tissue arises from the mesoderm, which is the embryo's middle
layer. The mesonephric ducts are a set of primitive reproductive ducts. Oocytes
are eggs.
11.The nurse teaches a class that which of the following is the first gender change
to occur in the embryo?
A. Destruction of the "Y" chromosome in the female embryo
B. Development of dominance in the primitive duct structure
C. Formation of primitive external genitalia that are visible on ultrasound
D. Spermatogenesis and oogenesis in male and female embryos,
respectively - ANSWER: B
Differing male/female developmental changes in the mesonephric and
paramesonephric ducts include the development of dominance in one set of the
ducts. Mesonephric ducts become dominant in males; paramesonephric ducts
become dominant in females. This is the first gender change that occurs. Gender is
determined by the presence of an XX or XY pair of chromosomes; none are
destroyed. External genitalia are usually not visible before 12 weeks of gestation,
when androgens begin to stimulate their growth. Spermatogenesis occurs in
