Introduction
This comprehensive examination is designed to assess the advanced practice
nursing student's competency in differential diagnosis and primary care
clinical reasoning. It evaluates the integration of evidence-based practice,
diagnostic test interpretation, and guideline-concordant management of acute
and chronic conditions across the lifespan. The exam utilizes a multiple-choice
format with scenario-based questions that reflect real-world primary care
clinical situations. Emphasis is placed on the application of clinical decision
rules, preventive care guidelines, and patient-centered communication
strategies essential for safe, effective nurse practitioner practice. This
,assessment aligns with Next Generation NCLEX (NGN) standards and APRN
competency requirements.
SECTION ONE: QUESTIONS 1 - 200
1. A 29-year-old woman presents with 6 months of crampy abdominal
pain relieved by defecation, intermittent diarrhea, and bloating. She
denies weight loss, fever, or rectal bleeding. Her physical exam is
normal. Which of the following is the MOST appropriate next step in
evaluating this patient's symptoms?
A. Immediately schedule colonoscopy with random biopsies
B. Order stool studies including fecal fat, weight, laxative screen, and tests for
microorganisms
C. Begin empiric treatment for ulcerative colitis without further testing
D. Refer urgently for abdominal CT with contrast
B. Order stool studies including fecal fat, weight, laxative screen, and tests
for microorganisms
RATIONALE: In IBS-like presentations with diarrhea as the dominant
symptom, the recommended approach includes thyroid testing and stool
studies for fecal fat, stool weight, laxative content, microorganisms, and celiac
serology to exclude organic causes before confirming IBS.
2. A 48-year-old man reports burning chest pain after large meals that
worsens when lying down and improves with antacids. He denies
dysphagia, weight loss, or GI bleeding. Which is the MOST likely
diagnosis?
A. Acute cholecystitis
B. Gastroesophageal reflux disease (GERD)
C. Peptic ulcer disease
D. Acute pancreatitis
B. Gastroesophageal reflux disease (GERD)
, RATIONALE: Classic symptoms of GERD include burning chest pain after
meals that worsens when recumbent and improves with antacids. The
absence of alarm symptoms (dysphagia, weight loss, bleeding) supports an
initial diagnosis of GERD without immediate invasive testing.
3. A 45-year-old man with typical heartburn and sour taste in his mouth
several times per week for 3 months has no alarm symptoms. You
suspect GERD. What is the MOST appropriate initial management
strategy?
A. Schedule EGD within 1 week
B. Start an H2 blocker for 2 weeks
C. Start a proton pump inhibitor (PPI) for 8 weeks
D. Recommend lifestyle modifications only
C. Start a proton pump inhibitor (PPI) for 8 weeks
RATIONALE: GERD management emphasizes acid suppression with PPIs
as first-line pharmacologic therapy, especially in patients with persistent
symptoms, along with appropriate diagnostic evaluation for dysphagia.
4. A 28-year-old woman reports 6 months of crampy lower abdominal
pain relieved by defecation, with alternating constipation and loose
stools. She denies weight loss, GI bleeding, or nocturnal symptoms.
Exam and basic labs are normal. What is the MOST likely primary
diagnosis?
A. Ulcerative colitis
B. Irritable bowel syndrome
C. Celiac disease
D. Chronic pancreatitis
B. Irritable bowel syndrome
RATIONALE: IBS is characterized by recurrent abdominal pain related to
defecation with changes in stool frequency and/or form and absence of alarm
features or significant objective abnormalities.
, 5. A 63-year-old man presents with cramping lower abdominal pain and
bloody diarrhea. He is hypotensive and tachycardic. He has extensive
atherosclerotic cardiovascular disease. Which diagnosis is MOST
consistent with this presentation?
A. Irritable bowel syndrome
B. Ischemic colitis
C. Ulcerative colitis
D. Celiac disease
B. Ischemic colitis
RATIONALE: Acute onset of cramping abdominal pain with bloody
diarrhea in a patient with atherosclerotic cardiovascular disease is classic for
ischemic colitis, which results from reduced blood flow to the colon.
6. A 35-year-old man presents with acute onset of severe right lower
quadrant abdominal pain, fever, nausea, and anorexia. On
examination, he has rebound tenderness at McBurney's point. Which
of the following is the most appropriate next step?
A. Outpatient observation with oral antibiotics
B. Immediate surgical consultation
C. Abdominal ultrasound
D. CT scan of the abdomen and pelvis with contrast
B. Immediate surgical consultation
RATIONALE: The presentation of acute right lower quadrant pain with
peritoneal signs (rebound tenderness at McBurney's point) is consistent with
acute appendicitis. Immediate surgical consultation is indicated for possible
appendectomy.
7. A 55-year-old woman presents with epigastric pain that occurs 2-3
hours after meals and is relieved by food or antacids. She also reports
nocturnal pain that awakens her from sleep. What is the MOST likely
diagnosis?
A. GERD
