Nursing251: Genetics and Genomics Final Questions With
Complete Solutions
a ____ is a type of cancer causing gene that promotes cancer by
activating cell division at inappropriate time or place Correct
Answer oncogene
a 21 year old woman who has two brothers with duchenne
muscular dystrophy asks whether carrier status testing is
appropriate for her. what is the best response Correct Answer
testing could be beneficial because your risk for being a carrier
is approximately 50%
a 23 year old man states that he hears Elvis talking to him.
although somewhat anxious, his mood is normal. what's his
diagnosis Correct Answer schizophrenia
a 31 year old man has been diagnosed with chronic obstructive
pulmonary disease as a result of being homozygous for the ZZ
mutation of the alpha1-antitripsin (AAT) gene alleles. his wife
doesn't have the mutation. he is worried about his kids getting it.
how do you respond Correct Answer because your kids will
each only have one mutated gene allele, the risk is primarily
dependent on chronic environmental exposure to inhalation
irritants
a common situation in which two or mas digits are fused
together Correct Answer syndactyly
,a condition where the fibers are abnormally long and slender in
comparison to the palm of the hand Correct Answer
arachnodactyly
a diagnostic hallmark of bipolar disorder is Correct Answer
mania
a point mutation that changes a codon specifying an amino acid
into a stop codon is called Correct Answer a nonsense
mutation
a primary structural defect occurring during the growth or
development of a tissue or organ Correct Answer
malformation
a son with achondroplasia is born to parents with no family
history of the disease. what is the most likely explanation for the
disorder? Correct Answer the gamete of one parent had a
spontaneous mutation
a woman whose hemoglobin S-levels are less than 1% has a
brother with sickle cell disease and both parents have been
diagnosed as carriers for the disorder. she asks what her risks are
of having a child with sickle cell disease. what is the best
response Correct Answer because you do not have the trait,
you cannot have a child with sickle cell disease regardless of
your partners sickle cell status
all of the following diseases belong to the autism spectrum
disorders except Correct Answer attention deficit
hyperactivity disorder
, alleles are Correct Answer alternative forms of a gene
an 85 year old patient states that she doesn't perform breast self
exam because there is no history of breast cancer in her family.
what is the best response Correct Answer breast cancer can be
found more frequently in some families; however, the risk for
general nonfamilial breast cancer increases with age
an affected individual is homozygous for the abnormal gene
having inherited an abnormal allele from each parent, both of
whom are unaffected heterozygous carriers Correct Answer
autosomal recessive
an individual with the chromosomal description 45, X would be
a Correct Answer female with turner syndrome
an individual with two normal sets of autosomes and a single x
chromosome had Correct Answer turner syndrome
an obese patient (BMI 35) says "it's all genetics, why even try".
how do you respond? Correct Answer even with a large
genetic component, obesity can be reduced by sensible diet and
exercise
atherosclerosis is the term used to describe Correct Answer
narrowing of the coronary arteries
autosomal dominant Correct Answer trait expressed
regardless of whether the person is homozygous or heterozygous
for the dominant allele
