Question 1: Celiac Disease
A patient is being evaluated for celiac disease. The nurse understands that
which of the following statements about celiac disease is correct?
A) It is caused by an autoimmune response to gluten that damages the
large intestine
B) The immune system sees gluten as a foreign invader, damaging the
lining of the small intestine
C) Testing includes IgA-tTG only
D) The patient should avoid gluten for 2 weeks before testing to ensure
accurate results
Answer: B
Rationale: Celiac disease is an autoimmune condition where the immune
system identifies gluten as a foreign invader, leading to damage of the
small intestine lining (not the large intestine). Testing typically includes
both IgA-tTG AND Total IgA (option C is incomplete). Importantly, patients
must continue a gluten-containing diet prior to testing because eliminating
gluten can cause false-negative results (option D is incorrect).
,Question 2: Sjögren's Syndrome
A 65-year-old woman with a history of rheumatoid arthritis presents with
complaints of dry eyes and dry mouth. The nurse anticipates which
diagnostic finding?
A) Positive ANA only
B) Positive SSA and SSB antibodies
C) Elevated TSH
D) Positive anti-acetylcholine receptor antibodies
Answer: B
Rationale: Sjögren's syndrome is an immune disorder characterized by dry
eyes (xerophthalmia) and dry mouth (xerostomia). It typically affects older
women or patients with other autoimmune conditions like RA and Lupus.
The hallmark diagnostic finding is positive SSA and SSB antibodies. Anti-
acetylcholine receptor antibodies are associated with Myasthenia Gravis,
not Sjögren's.
Question 3: Cinnamon Effects
A patient asks the nurse about the health benefits of cinnamon. Which of
the following is NOT a known effect of cinnamon?
A) Decreases glucose by acting like insulin at the cellular level
B) Decreases cholesterol
, C) Increases blood pressure
D) Decreases blood pressure
Answer: C
Rationale: Cinnamon has been shown to decrease glucose levels by acting
like insulin at the cellular level, decrease cholesterol, and decrease blood
pressure. It does NOT increase blood pressure. Patients should be
counseled on these potential effects, especially if they are on medications
for diabetes, hyperlipidemia, or hypertension.
Question 4: Hypoplastic Left Heart Syndrome (HLHS)
A newborn is diagnosed with Hypoplastic Left Heart Syndrome. Which of
the following structures is NOT underdeveloped in this condition?
A) Left ventricle
B) Mitral valve
C) Right ventricle
D) Ascending aorta
Answer: C
Rationale: In HLHS, the left side of the heart is not fully developed. This
includes the left ventricle, mitral valve, aortic valve, ascending aorta, and
atrial septal defect. The right ventricle is typically normal and works to
compensate for the left side. During the first few days of life, the Patent
Ductus Arteriosus (PDA) and Patent Foramen Ovale (PFO) assist with blood
flow. Diagnosis is made by echocardiogram, and treatment is surgical.
