WGU D236 FINAL PATHOPHYSIOLOGY 2025 LATEST
EXAM WITH CURRENTLY TESTING Q&A (COMPLETE
& VERIFIED) GRADE A
1. A newborn exhibits the manifestations of a genetic disorder. A five- generation family
history of each parent does not indicate the presence of the disorder. Which type of
mutation does the nurse recognize?
An undetected genetic defect in one of the parents An
undetected defect in an earlier generation
An alteration that likely occurred spontaneously
Feedback: This is correct. A mutation can occur spontaneously because of environmental
influences. This is the most likely cause based on the other factors examined.
One that changes both the DNA and RNA sequence
1
,2. Which defines translation in protein synthesis?
Process of DNA synthesis
Process of protein synthesis from RNA
Feedback: This is correct. The process of protein synthesis from RNA at ribosomes is called
translation.
Process of ribosome formation
Process of RNA synthesis Correct
3. Which definition applies to the term karyotype?
All the chromosomal pairs in an individual
Feedback: This is correct. Each individual has a fixed number of chromosomes and gene
patterns. This overall picture is a karyotype.
All the abnormal chromosomal pairs in an individual All the
chromosomal pairs of a species
All the normal chromosomal pairs in an individual
4. The human genome is estimated to be composed of between 20,000 and 25,000 genes
and has a specific arrangement of nucleotide bases, which carry a code for constructing
proteins. Which additional characteristic is present in genes?
Up to five bases code for one amino acid, so an average gene can code for 10,000 amino
acids
Intron sequences provide coding information for protein synthesis
Only about 50% of the genome is known to include the protein-coding sequences Genes have
codons that signal when protein production should begin or should stop Feedback: This is correct.
Codons exist within genes that signal that protein production should begin or should stop.
5. Genomics is the study of the interactions of all the nucleotide sequences within an
organism. Which statement regarding genomics is correct? Genomics recognizes genes
as the basic units of heredity
Feedback: This is correct. Each DNA molecule contains many genes, which are the basic units
of heredity. A gene is a specific arrangement of nucleotide bases, which carry a code for
constructing proteins.
Genomics is about the expression of genes
The nitrogen base in RNA is thymine instead of uracil DNA
is a single structure that can be broken down
6. During fertilization each parent contributes to the DNA being passed on to the
offspring. Which genetic expression in the offspring is validation of the genetic
contribution by a parent?
2
, The sex of the offspring
Feedback: This is correct. Each chromosome carries the genes for certain traits, so except for
those genes located on the sex chromosomes, everyone has two copies of each gene. The
female genotype is usually XX, and the male genotype is usually XY. The sex of the offspring is
determined by the male; XX results in a female, XY in a male. Hair color of the offspring
A client is diagnosed with degenerative disc disease. Which form of physical therapy does
the nurse anticipate the health-care provider will prescribe to reduce the movement of
the spine and enhance the healing process?
Heat and cold packs
Braces
Feedback: This is correct. Braces are a type of physical therapy that prevent movement of
the spine and facilitate the healing of spinal stenosis.
Electrotherapies
Massage
2. A nursing instructor is teaching a group of nursing students the causes of spinal
nerve impingement. Which statement made by the student indicates the need for
further teaching?
“Herniated discs may cause spinal nerve impingement.”
“Disc thickening may cause spinal nerve impingement.”
Feedback: This is correct. Disc thinning, not thickening, may cause spinal nerve impingement;
therefore, the nursing student’s response is incorrect and indicates the need for further teaching.
“Compression of the disc may cause spinal nerve impingement.”
“Osteocyte formation may cause spinal nerve impingement.” Correct
1/1 Points
3. The primary care provider recommends measuring the trabecular bone density in a
client’s spine. For which diagnostic test does the nurse prepare the client?
Electromyography (EMG)
Quantitative computerized tomography (QCT) scan
Feedback: This is correct. QCT scans are used to measure trabecular bone density in the spine.
X-ray
Magnetic resonance imaging (MRI) scan
Correct
1/1 Points
4. When assessing a client with a musculoskeletal disorder, the nurse finds lack of
sensation in the dermatome areas of the lower extremity L5. The nurse suspects lumbar
sprain/strain. Which does the nurse expect the health-care provider to prescribe in this
situation?
X-ray and dual energy x-ray absorptiometry scan of the spine
Anteroposterior and lateral x-rays of the lumbar spine
Feedback: This is correct. A client with a lumbar sprain/strain lacks sensation in the dermatome
areas of the lower extremity. Anteroposterior and lateral x-rays of the lumbar spine should be
routinely obtained to exclude a fracture, rheumatic disease, or a tumor growth and to evaluate
degenerative joint disease as well as overall spinal alignment.
