WGU D027 OA Final Exam 2026 | Verified Answers |
Exam Prep
1. What is the estimated normal ejection fraction
65% +/- 8%
60% +/- 8%
55% +/- 10%
70% +/- 5%
2. Describe why ACE inhibitors are often recommended for diabetic patients
with hypertension.
ACE inhibitors are used to increase insulin sensitivity in diabetic
patients.
ACE inhibitors help protect kidney function and lower blood
pressure in diabetic patients.
ACE inhibitors primarily reduce heart rate, which is not beneficial for
diabetic patients.
ACE inhibitors are primarily used for treating high cholesterol levels.
3. Describe why combining an angiotensin II Receptor Blocker (ARB) with ACE
inhibitors is generally avoided.
There are no significant interactions between ARBs and ACE inhibitors.
ARBs and ACE inhibitors work synergistically to lower blood pressure.
Combining ARBs with ACE inhibitors can increase the risk of kidney
dysfunction and hypotension.
ARBs are used to treat the side effects of ACE inhibitors.
,4. If a patient with Crohn's disease presents with severe abdominal pain and
imaging shows thickening of the bowel wall, what might this indicate
regarding the microscopic findings?
Absence of inflammatory cells
Decreased mucosal integrity
Presence of diverticula
Increased transmural inflammation
5. If a patient on statin therapy reports experiencing unexplained muscle pain,
what should be the immediate course of action?
Advise the patient to continue the statin without any changes.
Refer the patient to a physical therapist for muscle strengthening.
Increase the dosage of the statin to alleviate muscle pain.
Evaluate the patient for possible rhabdomyolysis and consider
discontinuing the statin.
6. Describe the significance of transmural inflammation in the diagnosis of
Crohn's disease.
Transmural inflammation is only seen in ulcerative colitis.
Transmural inflammation is a sign of benign conditions.
Transmural inflammation suggests a viral infection in the bowel.
Transmural inflammation indicates that the inflammation affects all
layers of the bowel wall, which is a hallmark of Crohn's disease.
7. Patients starting cholinesterase inhibitors should be instructed that they may
experience the following side effects:
, tinnitus, vertigo, and hearing loss
nausea, vomiting, and diarrhea
numbness and tingling in the extremities
headache and confusion
8. If a patient diagnosed with Hashimoto's disease presents with symptoms of
fatigue and weight gain, what would be the most appropriate initial treatment
approach?
Increased iodine intake
Thyroid hormone replacement therapy
Antibiotics
Surgery to remove the thyroid gland
9. A patient taking Florinef presents with elevated blood pressure and low
potassium levels. What might be the underlying cause?
Adrenal insufficiency
Dietary potassium deficiency
Kidney dysfunction
Side effects of Florinef
10. What is Klinefelter syndrome?
2 or more X chromosomes in males, causing low muscle tone,
breast growth, less hair, and poor coordination
2 or more Y chromosomes in males, causing speech impairment,
difficulty reading, and excess hair growth
, A hormone disorder, in which excess estrogen is produced in males,
causing less hair growth, adrenal tumors, and cardiac disorders
11. Which long-term medications are recommended for patients following
myocardial infarction (MI)?
Diuretics and calcium channel blockers
Antibiotics and antifungals
Anticoagulants and antiplatelet agents
Aspirin, β-blocker, ACE inhibitor, and statin
12. Which is an oncogene?
BRCA1
TP53
BRCA2
RET
13. What is the primary diagnostic test used to identify postural orthostatic
tachycardia syndrome?
Blood pressure monitoring
Electrocardiogram
Holter monitor
Tilt table test
14. If a patient has an ejection fraction of 45%, what might this indicate about
their heart health?
The patient is at risk for hypertension.
