Latest Solved Update
Fetal circulatio... [Show More] n differs from the circulatory path of the newborn infant. In utero the fetus
has a hole connecting the right and left atria of the heart. This allows oxygenated blood
to quickly pass to the major organs of the body. What is this hole called? - ANSForamen ovale
Explanation:
The foramen ovale is a hole that connects the right and left atria so the majority of
oxygenated blood can quickly pass into the left side of the fetal heart, go to the brain,
and move to the rest of the fetal body.
A nursing student is explaining to a newly pregnant woman what happens during each
stage of fetal development. At which stage does the nurse inform the woman that the
lungs are fully shaped? - ANS-end of 16 weeks
Explanation:
At the end of 16 weeks, the lungs are fully shaped, fetus swallows amniotic fluid,
skeletal structure is identifiable, downy lanugo hair is present on the body, and sex can
be determined using ultrasound.
A pregnant client is scheduled to undergo chorionic villus sampling (CVS) to rule out
any birth defects. Ideally, when should this testing be completed? - ANS-10 to 12
weeks' gestation
Explanation:
Chorionic villus sampling (CVS) is typically performed between 10 to 12 weeks'
gestation. Sometimes it may be offered up to 14 weeks. The test is not conducted
before 10 weeks' gestation.
A couple has just been notified that their unborn child carries a genetic disorder. The
couple expresses concern that the insurance company will not cover the costs
associated with the medical bills for the child. What is the most appropriate response by
the nurse? - ANS-"There are laws in place that prohibit that from happening."
Explanation:
The Genetic Information Nondiscrimination Act of 2008 prohibits insurance companies
from denying coverage or charging higher premiums based solely on genetic
predisposition.
The nurse is seeing a client who is going to be married in a month. This client has a
history of Huntington disease in her family. The genetic testing has come back, and the
client has just been told she carries the gene for Huntington disease and will develop
the disease when she gets older. The client asks the nurse if this information is
confidential and if it will remain that way. The nurse explains to the client that her family
should be told and so should her fiancé. The client forcefully tells the nurse "no." She is
not going to tell either her family or her fiancé. What is the nurse's best response? -
ANS-"I will respect your wishes and keep your information confidential. I do wish you
would reconsider though."
Explanation:
The nurse must honor the client's wishes and should be sure the client is aware that this
action will be done. Although the nurse may ask the client to consider the potential
benefit this information may have for other family members, this reply is not the critical
or best one. The other two replies should not be stated, because the nurse has to honor
the wishes of the client.
A pregnant woman asks the nurse about medications taken during pregnancy and if
they cross the placental barrier. What response by the nurse is appropriate? - ANS-
"Some medications cross the placental barrier, so be sure to discuss medications with
your provider."
Explanation:
Some medications cross the placental barrier, so the nurse will encourage the woman
to talk more specifically with her provider. The nurse would be in error to state that all or
none cross the placental barrier. Regardless of the route, some medications cross the
barrier and are unsafe during pregnancy. The first trimester is the most dangerous time
to take a medication that crosses the placental barrier.
A client at a preconception screening appointment indicates to the nurse that she is a
carrier of muscular dystrophy, an X-linked recessive trait. Her partner does not have the
trait. Which statement made by the client indicates an understanding of the
implications? - ANS-"Each time I have a child, there is a 25% chance a female child will
be a carrier."
Explanation:
X-linked recessive inheritance affects more males than females. There is no male-tomale transmission but any man who is affected with an X-linked recessive disorder will
have carrier daughters. If a woman is a carrier, there is a 25% chance she will have an
"affected son," a 25% chance that her daughter will be a "carrier," a 25% chance that
she will have an "unaffected" son, and a 25% chance her daughter will be a
"noncarrier."
The nurse is working for an obstetrician. Which couple(s) may benefit from genetic
counseling? Select all that apply. - ANS-The father-to-be is 58 years old.
The parents-to-be are cousins.
The parents-to-be are of African heritage.
The parents-to-be have a child who was born blind and deaf.
Explanation:
People who should receive genetic counseling prior to our during pregnancy: couple
where the father is older than 50 years of age, if the couple have at least one common
ancestor (consanguinity), couple with one or both parents with African heritage, and
couple who have a biologic child who was born blind or deaf. A mother-to-be older than
35 years of age may also benefit from genetic counselingterm-8.
The term that describes the percentage of individuals known to carry the gene for a trait
and who actually manifest the condition is: - ANS-penetrance.
Explanation:
Penetrance is the percentage of persons known to have a particular gene mutation and
who actually show the trait. Pedigree is a first step in establishing the pattern of
inheritance. A genotype consists of the genes and variations therein that a person
inherits from his or her parents. Variable expression is the variation in the degree to
which a trait is manifested.
A client with symptoms of pregnancy is having an ultrasound is to determine the
gestation of the pregnancy. The nurse explains that the visualization of different
developmental milestones correlates with the gestation of the pregnancy. Place the
following developmental milestones in order, from earliest to latest, as they appear
during the first trimester. Use all options. - ANS-Gestational sac
Cardiac pulsation
Spine formation
Formation of limb buds
Explanation:
A gestational sac appears between 4 to 5 weeks' gestation. Cardiac pulsation begins at
6 weeks' gestation, the spine is visible at 7 weeks' gestation, and evidence of four limb
buds is present at 8 weeks' gestation.
At a prenatal checkup with a client at 7 weeks' gestation, the nurse would identify what
as a normal finding? - ANS-Fetal heart sounds are heard.
Explanation:
Although the heart is not fully developed, it begins to beat at week 5, and a regular
rhythm and can be heard at week 7. Quickening is felt around week 13. Gender identity
can be determined at weeks 9 to 12. The startle reflex can be seen around weeks 21 to
24.
A recently married couple come to the prenatal clinic because they are concerned about
genetic testing. The husband is of Jewish heritage. The nurse should recommend the
couple undergo genetic testing to determine if the fetus has which disorder common
among Ashkenazi Jews (Jews of Eastern European lineage)? - ANS-Tay-Sachs
disease
Explanation:
Tays-Sachs disease is a autosomal recessive disorder that occurs primarily in
Ashkenazi Jews.
