Chap 6 - Genetics, Conception, andFetal Development
A couple has been counseled for genetic anomalies. They ask you, "What is
karyotyping?" Your best response is:
a. "Karyotyping will reveal if the baby's lungs are mature."
b. "Karyotyping will reveal if your baby will develop normally."
c. "Karyotyping will provide information about the gender of the baby and the
number and structure of the chromosomes."
d. "Karyotyping will detect any physical deformities the baby has." - answer
✅✅c. "Karyotyping will provide information about the gender of the baby and
the number and structure of the chromosomes."
Karyotyping provides genetic information such as gender and chromosome
structure. The L/S, not karyotyping, reveals lung maturity. Although
karyotyping can detect genetic anomalies, the range of normal is
nondescriptive. Although karyotyping can detect genetic anomalies, not all
such anomalies display obvious physical deformities. The term deformities is
a nondescriptive word. Furthermore, physical anomalies may be present that
are not detected by genetic studies (e.g., cardiac malformations).

The lecithin/sphingomyelin ratio, not karyotyping, reveals lung maturity.

A father and mother are carriers of phenylketonuria (PKU). Their 2-year-old
daughter has PKU. The couple tells the nurse that they are planning to have
a second baby. Because their daughter has PKU, they are sure that their next
baby won't be affected. What response by the nurse is most accurate?
a. "Good planning; you need to take advantage of the odds in your favor."
b. "I think you'd better check with your doctor first."
c. "You are both carriers, so each baby has a 25% chance of being affected."
d. "The ultrasound indicates a boy, and boys are not affected by PKU." -
answer ✅✅c. "You are both carriers, so each baby has a 25% chance of
being affected."
, The chance is one in four that each child produced by this couple will be
affected by 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 key finding from the Human Genome Project is:
a. Approximately 20,000 to 25,000 genes make up the genome.
b. All human beings are 80.99% identical at the DNA level.
c. Human genes produce only one protein per gene; other mammals produce
three proteins per gene.
d. Single gene testing will become a standardized test for all pregnant clients
in the future. - answer ✅✅a. Approximately 20,000 to 25,000 genes make up
the genome.
Approximately 20,000 to 25,000 genes make up the human genome; this is
only twice as many as make up the genomes of roundworms and flies.
Human beings are 99.9% identical at the DNA level. Most human genes
produce at least three proteins. Single gene testing (e.g., alpha-fetoprotein)
is already standardized for prenatal care.
