, Question 2 pts
If an ovum has chromosomal nondisjunction, which conditions(s) could result
in the embryo?
Correct! Monosomies and trisomies
Nondisjunction, or failure of a chromosome to separate during meiosis,
results in an ovum with two copies of the chromosome and an ovum with
no copies of the chromosome. When these ova encounter a male
gamete (sperm), the resulting embryo will have either an extra copy of
the chromosome (trisomy) or one copy of the chromosome (monosomy).
Chromosomal translocation
Broken chromosomes
Normal cell division
Question 3 pts
If a patient has Gaucher disease, which of the following organ(s) should the
nurse monitor?
Liver
Spleen
CNS/brain
Correct! All of the above
Gaucher disease is caused by the accumulation of a fatty substance
called glucocerebroside in the spleen, liver, and CNS. It also affects the
lungs and brain.
, Question 4 pts
An individual who is heterozygous for a gene has:
Correct! alleles at a given locus that are different from one another.
An individual who is heterozygous for a gene has alleles at a given locus
that are different from one another.
alleles at a given locus that are the same.
alleles at different loci that are the same.
a recessive gene on chromosomal pairs.
Question 5 pts
A nurse recalls that adaptive cellular mechanisms function to:
treat disease.
Correct! protect cells from injury.
Adaptive cellular mechanisms actually help cells adjust to environmental
changes, thereby protecting them from injury and death. Aging is a
complex physiologic process that occurs despite cellular adaptations.
Cellular adaptations help prevent, rather than speed up cell death.
Exogenous therapies, such as medications and surgery, are used to
treat disease.
prevent cellular aging.
speed up cellular death.
, Question 6 pts
The nurse is caring for a new mother who just gave birth to a baby with Down
syndrome. The nurse explains that this syndrome is a result of trisomy with
which chromosome?
6
8
14
Correct! 21
The karyotype of an individual with Down syndrome shows trisomy 21.
Question 7 pts
The nurse documents "tattooing and stippling" in a trauma patient. Which
type of injury does this patient have?
Asphyxial injuries
Blunt force injuries
Correct! Gunshot wounds
Tattooing and stippling are caused by gunpowder and occur on the skin
surrounding the entrance wound. Asphyxial injuries are caused by a
failure of cells to receive or use oxygen. Blunt force injuries involve
tearing, shearing, or crushing of tissues. Injury to cells due to pathogens
are referred to as "infectious injuries."
