1. A community health nurse is planning a prenatal education program.
Which topic is most important to include to address the leading preventable
cause of intellectual disability?
A) The importance of folic acid supplementation
B) The teratogenic effects of alcohol consumption
C) The benefits of breastfeeding
D) The schedule for routine immunizations
Correct Answer: The teratogenic effects of alcohol consumption
Rationale: Fetal alcohol syndrome is the leading preventable cause of
intellectual disability. Alcohol is a teratogen that crosses the placenta and
can cause lifelong cognitive and physical impairments. While folic acid,
breastfeeding, and immunizations are important, they do not address the
leading preventable cause.
2. A nurse is teaching a group of women about the menstrual cycle. Which
hormonal event triggers ovulation?
A) A surge in estrogen
B) A surge in luteinizing hormone (LH)
C) A steady increase in progesterone
D) A decrease in follicle-stimulating hormone (FSH)
Correct Answer: A surge in luteinizing hormone (LH)
Rationale: Ovulation is triggered by a surge in luteinizing hormone (LH) from
the anterior pituitary gland. This surge typically occurs around day 14 of a
,28-day cycle. Estrogen rises before the surge, progesterone rises after
ovulation, and FSH stimulates follicle development.
3. A nurse is reviewing the components of fetal circulation. Which structure
connects the pulmonary artery to the aorta in the fetus, bypassing the lungs?
A) Foramen ovale
B) Ductus venosus
C) Ductus arteriosus
D) Umbilical vein
Correct Answer: Ductus arteriosus
Rationale: The ductus arteriosus is a fetal vessel that connects the
pulmonary artery to the aorta, allowing blood to bypass the non-functioning
fetal lungs. The foramen ovale is an opening between the atria, the ductus
venosus bypasses the liver, and the umbilical vein carries oxygenated blood
from the placenta.
4. A pregnant client asks the nurse about the function of the amniotic fluid.
Which response is most accurate?
A) It provides nutrients to the fetus
B) It cushions the fetus and allows for movement
C) It exchanges oxygen and carbon dioxide
D) It produces hormones to maintain pregnancy
Correct Answer: It cushions the fetus and allows for movement
Rationale: Amniotic fluid cushions the fetus, allows for movement and
musculoskeletal development, maintains temperature, and prevents
compression of the umbilical cord. Nutrients and oxygen exchange occur
,through the placenta, and hormone production is primarily the role of the
placenta and corpus luteum.
5. A nursing instructor is explaining the process of fertilization. Where does
fertilization typically occur?
A) In the uterus
B) In the ovary
C) In the fallopian tube (ampulla)
D) In the cervix
Correct Answer: In the fallopian tube (ampulla)
Rationale: Fertilization typically occurs in the ampulla (outer third) of the
fallopian tube. The fertilized ovum then travels to the uterus for
implantation. The ovary releases the ovum, the uterus is the site of
implantation and growth, and the cervix is the lower part of the uterus.
6. A client in early pregnancy asks the nurse about the hormone that
maintains the pregnancy until the placenta takes over. Which hormone is
responsible?
A) Estrogen
B) Progesterone
C) Human chorionic gonadotropin (hCG)
D) Oxytocin
Correct Answer: Progesterone
Rationale: Progesterone is produced by the corpus luteum and maintains the
uterine lining and pregnancy until the placenta fully takes over hormone
production around 8-10 weeks of gestation. hCG is the hormone detected in
, pregnancy tests, estrogen supports uterine growth, and oxytocin stimulates
uterine contractions.
7. The nurse is assessing a newborn and notes the presence of fine, downy
hair on the shoulders and back. The nurse correctly documents this finding
as:
A) Vernix caseosa
B) Lanugo
C) Milia
D) Mongolian spots
Correct Answer: Lanugo
Rationale: Lanugo is fine, downy hair that covers the fetus and is typically
present on the shoulders, back, and extremities of premature and some term
newborns. Vernix caseosa is a white, cheesy protective coating, milia are
small white bumps on the face, and Mongolian spots are bluish-gray
pigmented areas.
8. A community health nurse is providing pre-conception counseling. Which
recommendation is most important for preventing neural tube defects?
A) Avoiding alcohol consumption
B) Taking 400-800 mcg of folic acid daily
C) Maintaining a healthy weight
D) Getting vaccinated against rubella
Correct Answer: Taking 400-800 mcg of folic acid daily
Rationale: Folic acid supplementation before and during early pregnancy
significantly reduces the risk of neural tube defects such as spina bifida.
