ANSWERS WITH COMPLETE

||NEWLY UPDATED 2026
Question 1
During prenatal development, which specific intrauterine component serves as a
vital physical buffer to cushion the developing fetus against external trauma while
simultaneously maintaining a stable, warm thermal environment? A. The placenta
B. The embryonic membranes C. The amniotic fluid D. The umbilical cord
✔✔ C. The amniotic fluid
Rationale: Amniotic fluid plays multiple critical roles in fetal development. It
acts as a liquid shock absorber, protecting the fetus from maternal abdominal
trauma, and acts as an insulator to maintain a constant, warm body temperature.
While the placenta manages nutrient and gas exchange, the embryonic membranes
enclose the cavity, and the umbilical cord handles vascular transport, it is the
amniotic fluid itself that directly provides cushioning and thermal stability.
Question 2
When assessing a couple experiencing difficulty conceiving, the fertility nurse
evaluates various modifiable health behaviors. Which of the following choices are
recognized as distinct risk factors that can impair reproductive health and
contribute to infertility? A. Maternal obesity B. Parental tobacco smoking C.
Heavy or chronic alcohol consumption D. All of the above
✔✔ D. All of the above
Rationale: Infertility can be significantly influenced by modifiable lifestyle
choices. Maternal obesity disrupts endocrine pathways, leading to ovulatory
dysfunction and hormonal imbalances. Parental tobacco smoking compromises
egg quality in women and lowers sperm count and motility in men. Heavy alcohol
consumption negatively impacts reproductive hormone production and fertility
parameters in both sexes. Implementing healthy lifestyle modifications is a
foundational first step to optimize a couple's chances of successful conception.
Question 3
,The maternal cardiovascular system undergoes profound physiological adaptations
to support the growing fetus. Which of the following alterations represents an
expected, normal cardiovascular change during a healthy pregnancy? A. Elevated
cardiac output B. Development of dependent lower-extremity edema C. Expansion
of total plasma volume D. All of the above
✔✔ D. All of the above
Rationale: Pregnancy triggers dramatic, healthy shifts in maternal hemodynamics.
Plasma volume expands significantly (by up to 50%) to ensure adequate placental
perfusion, which directly drives an increased cardiac output to meet metabolic
demands. Furthermore, as the growing uterus compresses the inferior vena cava,
venous return from the lower extremities slows down. This increased hydrostatic
pressure regularly results in dependent edema in the feet and ankles, making all
three options classic features of maternal cardiovascular adaptation.
Does a pregnant test depict ________ sigh of pregnancy
A. Probable
B. Presumptive
C. Positive -ANSWER.....A. Probable
Negele's Rule helps calculate what?
A. Date of LMP
B. EDD
C. GTPAL
D. Multiple births -ANSWER.....B. EDD
Based upon first day of last menstrual period
,Which of the following are maternal tasks of pregnancy?
A. Accepting the pregnancy
B. Identifying with the role of motherhood
C. Solving mother/daughter conflicts
D. All of the above -ANSWER.....D. All of the above
Prenatal classes provide the couple with:
A. Knowledge and confidence
B. Mental health counseling
C. Nursing-level knowledge
D. A birth plan -ANSWER.....A. Knowledge and confidence
Prenatal classes empower the couple to know, understand, and plan for pregnancy.
They gain skills to create their own birth plan and seek resources, if needed.
Which test best provides an answer to the question of whether or not the infant has
a congenital defect?
, A. Screening
B. Diagnostic test
C. Biophysical profile
D. Multiple marker screening -ANSWER.....B. Diagnostic test
Diagnostic tests, which are often invasive and can pose risks to the fetus, can
obtain a definitive answer on suspected congenital defects.
The multiple marker screenings identify:
A. Neural tube defects
B. Cerebral palsy
C. Hemolytic diseases
D. Cleft palate -ANSWER.....A. Neural tube defects
Multiple marker screenings can identify most open neural tube defects. They also
identify Down syndrome.
Who's at risk for gestational diabetes?
A. Obese pregnant women
