A client is 5 months pregnant. On a routine ultrasound scan, the physician
discovers that the fetus has a diaphragmatic hernia. The woman becomes
distraught and asks the nurse what she should do. Which response would be
most suitable?
a.Talk to the client, and refer her to a genetic counselor.
b.Suggest that the client travel to a fetal treatment center for intrauterine
surgery.
c.Tell her that everything is going to be fine.
d.Sit with the client, and calmly suggest that she consider terminating this
pregnancy. - ANS: A
Before the client makes any decisions, she should discuss this newly discovered
information with a genetic counselor. Genetic counselors can help with the
diagnosis and management of families affected by genetic conditions. The
discussion of potential surgery should be pursuant to genetic counseling.
Telling the woman that everything is going to be fine may give her false hope and
is not accurate. All options should be discussed with the genetic counselor.
Furthermore, the guiding principle for genetic counseling is nondirection, which
respects the right of the individual or family who are being counseled to make
autonomous decisions.
A client who is gravida 2 and 16 weeks of gestation comes in for her prenatal
appointment. Her 2-year-old daughter is with her and is wearing a sleeveless
top. While interacting with her daughter, you note axillary freckling and several
café-au-lait spots (>2 cm). In reviewing her chart, the nurse should assess for
documentation of which genetic disease?
a.Tay-Sachs disease
,b.Galactosemia
c.Neurofibromatosis (NF)
d.PKU - ANS: C
Clinical manifestations of NF may include axillary freckling and café-au-lait
spots. Tay-Sachs disease is an incurable lipid-storage disorder and is not
associated with café-au-lait spots. Galactosemia is an inborn error of
metabolism and is also not associated with café-au-lait spots. PKU is not
associated with café-au-lait spots. A child with PKU would have difficulty
manufacturing the liver enzyme phenylalanine.
A father and mother are carriers of phenylketonuria (PKU). Their 2-year-old
daughter has the condition. The couple tells the nurse that they are having a
second baby. Because their daughter has PKU, they are certain that this baby
will not be affected. Which response by the nurse is the most accurate?
a."Good planning. You need to take advantage of the odds that are in your
favor."
b."I think you'd better first check with your physician."
c."You are both carriers; therefore, each baby has a 25% chance of being
affected."
d."The ultrasound indicates a boy, and boys are not affected by PKU." - ANS: C
Each child conceived by this couple has a one-in-four chance of being affected
with the PKU disorder. This couple still has an increased likelihood of having a
child with PKU; having one child already with PKU does not guarantee that they
will not have another. These parents need to discuss their options with their
physician. However, an opportune time has presented itself for the couple to
receive correct teaching about inherited genetic risks. No correlation exists
between gender and inheritance of the disorder, because PKU is an autosomal
recessive disorder.
A new father has just been told that his infant has trisomy 18. Which identifying
physical feature is unique to an infant with this genetic disorder?
a.Microcephaly and capillary hemangiomas
, b.Epicanthal folds and a simian crease
c.Oblique palpebral fissures and Cri du chat syndrome
d.Rocker-bottom feet and clenched hands with overlapping fingers - ANS: D
Rocker-bottom feet and clenched hands with overlapping fingers are associated
with trisomy 18. Microcephaly and capillary hemangiomas are associated with
trisomy 13. Epicanthal folds and a simian crease are associated with trisomy 21
(Down syndrome). Deletion of the short arm of chromosome number 5 is
manifested by Cri du chat syndrome.
A nurse is assessing the knowledge of new parents of a child born with
Klinefelter syndrome. Which statement accurately describes this genetic
disorder?
a.Klinefelter syndrome is a sex chromosome abnormality.
b.It affects only female children.
c.The disorder is expressed as trisomy XYY.
d.The child with this disorder will grow to be infertile. - ANS: A
Klinefelter syndrome, also known as trisomy XXY, is a sex chromosomal
deviation that is expressed in males. Turner syndrome (monosomy X) is
displayed in females. Most males with Klinefelter syndrome are tall, may be
infertile, and are slow to learn; however, those who have mosaic Klinefelter
syndrome may be fertile as adults.
Which factor is least likely to influence the decision to undergo genetic testing?
a.Anxiety and altered family relationships
b.Cost of testing or denial of insurance benefits
c.Imperfection of test results
d.Ethnic and socioeconomic disparity associated with genetic testing - ANS: B
Testing is not 100% accurate and has a high percentage of false-negative
results. An individual may not take these results seriously and subsequently fail
