,WGU D027 OA Exam
Question 1
What is the gold standard for the suspected diagnosis of Celiac Disease?
A. Serologic testing for anti-tissue transglutaminase antibodies
B. Genetic testing for HLA-DQ2 and HLA-DQ8
C. Endoscopy with small intestine biopsy
D. Capsule endoscopy
Correct Answer: C. Endoscopy with small intestine biopsy
Rationale: Endoscopy with small intestine biopsy remains the gold
standard for diagnosing celiac disease, as it allows for direct visualization
and histologic confirmation of villous atrophy.
Question 2
A 44-year-old woman has recently been diagnosed with advanced
metastatic non-small-cell lung cancer. Genetic testing is ordered. A few
weeks later, the test results come back positive for a genetic mutation. The
APN starts osimertinib (Tagrisso). What type of genetic mutation does this
patient have?
A. ALK mutation
B. ROS1 mutation
C. KRAS mutation
D. EGFR mutation
Correct Answer: D. EGFR mutation
Rationale: Osimertinib (Tagrisso) is a third-generation EGFR tyrosine kinase
inhibitor specifically indicated for EGFR-mutated non-small-cell lung cancer.
Question 3
A 20-year-old male has slowly progressive symptoms including frequent
falls, toe walking since childhood, difficulty running/jumping, and trouble
changing from sitting to standing. Family history is not significant. Which
condition is most likely?
, A. Duchenne muscular dystrophy
B. Becker muscular dystrophy
C. Spinal muscular atrophy
D. Myasthenia gravis
Correct Answer: B. Becker muscular dystrophy
Rationale: Becker muscular dystrophy presents with later onset and slower
progression than Duchenne. Symptoms include gait abnormalities, proximal
muscle weakness (difficulty rising from sitting), and preserved ambulation
into adulthood.
Question 4
Which statement should the provider give the patient regarding the
pathophysiology of SLE and its relation to thrombocytopenia?
A. SLE causes direct destruction of megakaryocytes in the bone marrow
B. SLE disrupts immune homeostasis and promotes development of self-
reactive antibodies
C. SLE leads to vitamin K malabsorption
D. SLE increases splenic sequestration of platelets
Correct Answer: B. SLE disrupts immune homeostasis and promotes
development of self-reactive antibodies
Rationale: In SLE, loss of immune tolerance leads to autoantibodies,
including antiplatelet antibodies, which mediate immune
thrombocytopenia.
Question 5
A female patient has an elevated ferritin level found by her previous PCP.
She is asymptomatic with no past medical history. What should the
provider do next?
A. Repeat ferritin level in 6 months
B. Order a liver function test
C. Refer to hematology for therapeutic phlebotomy
