NSPN 7100 FINAL EXAM(QUESTIONS
AND ANSWERS 2026 LATEST EDITION)
ALL GRADED A+.
What are some short term benefits of preconception care? - CORRECT ANSWER
(S) --reducing the number of preterm births
-decreasing the number of unintended pregnancies
-lowering the risk of genetic disorders or environmental exposures
-reducing maternal and neonatal mortality
-improving maternal and child health outcomes
What day does the maternal-placental-embryonic circulation become in place to
allow the heart to beat? - CORRECT ANSWER (S) -Day 17
,When does the placenta develop? - CORRECT ANSWER (S) -Within the first week
of implantation
The villi erode the walls or ________ _____ _______ as they penetrate the
________, opening them up so that a lake of maternal blood forms, in which the
villi float. - CORRECT ANSWER (S) --maternal blood vessels
-decidua
The maternal blood circulates slowly, allowing fetal capillaries within the villi to
absorb nutrients and oxygen and to excrete waste. The _________ _____ are
capable of carrying out this fetal/maternal exchange by the third week after
conception. - CORRECT ANSWER (S) --chorionic villi
As the placenta continues to grow, when do the villi proliferate until? - CORRECT
ANSWER (S) -Approximately 18-20 weeks after conception, when the majority of
villi are established.
,Fetal/maternal exchange (of gases, nutrients, and wastes) occurs across or
through the cell membranes that line the outside of the chorionic villi. There is no
mixing of maternal and fetal blood unless there is a break in these membranes.
Can the baby have a completely different blood type than the mother? - CORRECT
ANSWER (S) -Yes
The placenta is not a "barrier" but a _____. - CORRECT ANSWER (S) --Sieve
-blood cannot pass through the cell membranes but other substances can such as,
drugs, infectious agents and maternal antibodies.
The placenta secretes 4 pregnancy hormones. What are they and how do they
function? - CORRECT ANSWER (S) -Human chorionic gonadotrophin (hCG)
(protein)
•preserves the function of the corpus luteum, ensuring a continued supply of
estrogen and progesterone needed to maintain pregnancy
Human placental lactogen (hPL) (Protein)
, •stimulates the maternal metabolism to supply nutrients for fetal growth
•increases maternal resistance to insulin, and facilitates glucose transport across
the placental membrane
•stimulates breast development in preparation for lactation
Progesterone (steroid)
•maintains endometrium
•decreases contractility of the uterus
•stimulates development of breast alveoli
•stimulates maternal metabolism
Estrogen (steroid)
•stimulates uterine growth and uteroplacental blood flow
•causes proliferation of breast glandular tissue
