150 Multiple-Choice Questions | Advanced/Hard Difficulty | For
Nurse Practitioner Students & Professionals
Section 1: Advanced Pathophysiology
(Questions 1–50)
1. A 62-year-old male with a 30-year history of gastroesophageal
reflux disease presents with progressive dysphagia to solids,
odynophagia, and a 15-pound weight loss over 3 months.
Endoscopy reveals a circumferential mass in the distal esophagus
with ulceration. Biopsy shows malignant cells with glandular
differentiation. Which of the following is the most likely
underlying pathological process?
A. Squamous cell carcinoma arising from chronic irritation
B. Adenocarcinoma arising from Barrett's esophagus
C. Leiomyosarcoma arising from smooth muscle
D. Lymphoma arising from mucosal-associated lymphoid tissue
E. Neuroendocrine tumor arising from enterochromaffin cells
,Correct Answer: B
Rationale: Chronic GERD can lead to Barrett's esophagus
(metaplasia of squamous epithelium to columnar epithelium),
which is a premalignant condition predisposing to esophageal
adenocarcinoma. The presence of glandular differentiation on
biopsy confirms adenocarcinoma. Squamous cell carcinoma is
associated with smoking and alcohol and does not show glandular
differentiation.
2. A 48-year-old female presents with progressive proximal
muscle weakness, a heliotrope rash on the eyelids, and Gottron's
papules over the metacarpophalangeal and interphalangeal
joints. Laboratory studies reveal elevated creatine kinase and
aldolase. Muscle biopsy shows perifascicular atrophy and
inflammatory infiltrate. Which of the following is the most
important malignancy screening in this patient population?
A. Colonoscopy for colorectal cancer
B. Mammography and pelvic ultrasound for breast and ovarian
cancer
C. Low-dose CT chest for lung cancer
D. PSA testing for prostate cancer
E. Upper endoscopy for gastric cancer
Correct Answer: B
Rationale: Dermatomyositis is associated with an increased risk of
malignancy, particularly in women over 40. The most commonly
associated malignancies in women are breast and ovarian cancer.
,Mammography and pelvic ultrasound are recommended screening
modalities. Colonoscopy and lung cancer screening are also
considerations but breast and ovarian are the most common in this
demographic.
3. A 55-year-old male with chronic alcoholism presents with
confusion, ataxia, and horizontal nystagmus. He reports a history
of poor dietary intake and recurrent vomiting. Which of the
following best describes the underlying pathophysiological
mechanism?
A. Thiamine deficiency leading to impaired glucose metabolism and
ATP production
B. Vitamin B12 deficiency leading to impaired myelin synthesis
C. Folate deficiency leading to impaired DNA synthesis
D. Niacin deficiency leading to impaired NADH production
E. Vitamin E deficiency leading to impaired antioxidant defense
Correct Answer: A
Rationale: Wernicke's encephalopathy is caused by thiamine
(vitamin B1) deficiency, which is essential for glucose metabolism.
Thiamine is a cofactor for several enzymes involved in carbohydrate
metabolism, including pyruvate dehydrogenase and alpha-
ketoglutarate dehydrogenase. Deficiency leads to impaired ATP
production and neuronal damage.
, 4. A 32-year-old pregnant woman at 34 weeks gestation presents
with headache, visual disturbances, and right upper quadrant
pain. Blood pressure is 165/105 mmHg and urine protein is 3+.
Laboratory studies reveal elevated AST, ALT, and low platelets.
Which of the following is the most likely diagnosis?
A. Preeclampsia with severe features
B. HELLP syndrome
C. Acute fatty liver of pregnancy
D. Gestational hypertension
E. Eclampsia
Correct Answer: B
Rationale: HELLP syndrome (Hemolysis, Elevated Liver enzymes,
Low Platelets) is a severe complication of preeclampsia. The
presence of headache, visual disturbances, right upper quadrant
pain, hypertension, proteinuria, elevated liver enzymes, and low
platelets is classic. HELLP syndrome can occur with or without
preeclampsia and is a medical emergency.
5. A 68-year-old female presents with progressive dyspnea on
exertion, orthopnea, and paroxysmal nocturnal dyspnea.
Echocardiography reveals a thickened, hyperdynamic left
ventricle with an ejection fraction of 70%. Which of the following
is the most likely underlying etiology?
A. Hypertrophic cardiomyopathy
B. Restrictive cardiomyopathy (amyloidosis)
C. Constrictive pericarditis
