WGU D027 Final Exam Questions & Answers: Genetic
Disorders and Management 2026 | Graded A+
1. Describe how phlebotomy helps in the treatment of hemochromatosis.
Phlebotomy increases iron absorption in the body.
Phlebotomy reduces iron levels in the body by removing blood,
which decreases iron overload.
Phlebotomy provides essential nutrients to patients with
hemochromatosis.
Phlebotomy is used to treat infections related to hemochromatosis.
2. Discuss the significance of understanding the populations affected by beta
thalassemia in clinical practice.
It is not significant as beta thalassemia can occur in any population.
It only matters for research purposes, not clinical practice.
Understanding the populations affected by beta thalassemia helps
in targeted screening and prevention strategies.
It helps in determining the cost of treatment options.
3. Describe how cholinesterase inhibitors function in the management of
Alzheimer's disease.
Cholinesterase inhibitors work by increasing levels of acetylcholine,
a neurotransmitter important for memory and learning.
Cholinesterase inhibitors block the production of neurotransmitters.
Cholinesterase inhibitors reduce the size of amyloid plaques in the
brain.
Cholinesterase inhibitors enhance blood flow to the brain.
,4. In humans, allopurinol can be used as treatment for gout because this drug is
a competitive inhibitor ofChoose one:
urate oxidase.
guanine deaminase.
xanthine oxidase
AMP deaminase.
5. A client newly diagnosed with diabetes tells the nurse, 'I can't take any insulin
made from pigs or cows.' Which of the following responses by the nurse is
best?
"The animals aren't hurt in the production of medications, so you don't
need to worry."
"Most insulin is synthetic now, so your insulin won't be from animal
sources."
"Medications that are derived from animals are typically less
expensive than synthetic medications, but synthetic insulin is
commonly available."
"Most insulin comes from animal sources, but I'm sure alternative
options are available."
6. You are taking care of a patient with the following assessment data: BP 88/43,
HR 127, and RR 25. On your lab work, you notice an elevated serum
osmolality. Which of the following interventions do you anticipate?
Administer normal saline intravenously
Encourage the patient to eat foods high in sodium content
Administer a diuretic
Administer a beta-blocker to reduce the heart rate
,7. Describe the significance of identifying early onset Alzheimer's disease in
patients.
It allows for immediate treatment with no long-term effects.
It helps in determining the genetic predisposition of the patient.
It is only relevant for patients over 70 years old.
Identifying early onset Alzheimer's disease is crucial for early
intervention and planning for care.
8. Hemolytic anemia is when
Insufficient magnesium levels
Insufficient vitamin B12 levels
Insufficient iron levels
The body breaks down more red blood cells than it produces
9. If a patient presents with gastrointestinal symptoms and a family history of
celiac disease, what diagnostic approach should be taken?
Order imaging studies to assess for structural abnormalities.
Immediately start a gluten-free diet without testing.
Perform a colonoscopy to check for tumors.
Conduct serological tests followed by an intestinal biopsy if
necessary.
10. What is the primary medication recommended for patients with HFrEF
according to the 2017 heart failure guidelines?
Losartan
Carvedilol
, Sacubitril/valsartan
Furosemide
11. Which intervention would the nurse provide to a pt with IBD who complains
of abdominal pain?
Encourage the pt to exercise by walking twice a day
Avoid administering analgesics
Advise the pt to drink milk to ease cramping
Observe for signs and symptoms of peritonitis
12. Describe the main characteristics of Duchenne Muscular Dystrophy (DMD)
and how they affect patients.
DMD is a neurological disorder that results in cognitive decline and
memory loss.
DMD is characterized by progressive muscle weakness and
degeneration, primarily affecting boys, leading to loss of
ambulation and respiratory complications.
DMD is a genetic disorder that primarily affects the heart, leading to
cardiovascular issues.
DMD is a condition that causes excessive muscle growth and
strength, affecting both genders equally.
13. Clinical signs of sickle cell anemia appear at:
1 year old
6 months old
9 months old
