NR 511 FINAL EXAM – DIFFERENTIAL DIAGNOSIS &
PRIMARY CARE PRACTICUM-CHAMBERLAIN UNIVERSITY
2026/2027 COMPLETE (150) CURRENT TESTING
QUESTIONS AND CORRECT ANSWERS WITH DETAILED
RATIONALES.
NR 511
Prepare effectively for the FNP NR511 Differential Diagnosis Final Exam with this
focused study resource. It supports review of clinical assessment, differential
diagnosis, common disease presentations, diagnostic reasoning, and evidence-based
clinical decision-making. Use the material to reinforce your knowledge, review high-
yield topics, and identify areas that may require additional study. This resource is
suited for family nurse practitioner students, advanced practice nursing learners, and
candidates preparing for the NR511 final examination.
MULTIPLE CHOICE.
SECTION 1: GASTROINTESTINAL DISORDERS (Questions 1–30)
Question 1:
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 (IBS)
C) Celiac disease
D) Chronic pancreatitis
Answer: B
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. Alarm features such as weight
loss, GI bleeding, or nocturnal symptoms would suggest organic pathology.

Question 2:
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) Initiate lifestyle modifications and empiric PPI trial
C) Order abdominal ultrasound
D) Refer to general surgery
Answer: B
Rationale: In patients with classic GERD symptoms and no alarm features, an
empiric trial of a proton pump inhibitor (PPI) combined with lifestyle
modifications (weight loss, elevation of head of bed, avoidance of trigger
foods) is the appropriate initial management. Endoscopy is reserved for
patients with alarm symptoms or inadequate response to therapy.
Question 3:
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. Physical exam is normal. What is the MOST
appropriate next step?
A) Immediately schedule colonoscopy with random biopsies
B) Order stool studies including fecal fat, stool weight, laxative screen, and
tests for microorganisms
C) Begin empiric treatment for ulcerative colitis
D) Refer urgently for abdominal CT with contrast
Answer: B
Rationale: In IBS-like presentations with diarrhea as the dominant symptom,
the study guide recommends thyroid testing and stool studies for fecal fat,
stool weight, laxative content, microorganisms, and celiac serology to exclude
organic causes before confirming IBS. IBS is a diagnosis of exclusion after
history, exam, and limited targeted tests rule out organic causes.

Question 4:
A 46-year-old woman with BMI 31 and typical reflux symptoms asks about
potential complications if GERD remains uncontrolled. Which complication is
most directly associated with chronic untreated GERD?
A) Esophageal varices
B) Barrett's esophagus
C) Esophageal candidiasis
D) Mallory-Weiss tear
Answer: B
Rationale: Barrett's esophagus is the most significant long-term complication
of chronic GERD, involving metaplastic changes in the esophageal mucosa
that increase the risk of esophageal adenocarcinoma.
Question 5:
A 43-year-old man with chronic NSAID use presents with burning epigastric
pain. What is the most likely diagnosis?
A) Gastroesophageal reflux disease
B) Peptic ulcer disease
C) Pancreatitis
D) Gallbladder disease
Answer: B
Rationale: Chronic NSAID use is a major risk factor for peptic ulcer disease,
which typically presents with burning epigastric pain that may be relieved by
food or antacids.
Question 6:
A 65-year-old patient presents with new-onset constipation, iron deficiency
anemia, and a change in bowel habits. What is the priority next step?
, Page 4 of 63
A) Start a high-fiber diet
B) Schedule colonoscopy
C) Order abdominal x-ray
D) Prescribe laxatives
Answer: B
Rationale: New-onset constipation after age 50 combined with iron
deficiency anemia is an alarm feature that warrants further evaluation for
structural pathology such as colorectal cancer. Colonoscopy is the
appropriate diagnostic test.
Question 7:
A patient with Crohn's disease is at increased risk for which complication?
A) Colon cancer
B) Strictures and fistulas
C) Toxic megacolon
D) All of the above
Answer: D
Rationale: Crohn's disease can lead to strictures, fistulas, abscesses, and an
increased risk of colorectal cancer. Toxic megacolon is more commonly
associated with ulcerative colitis but can occur in Crohn's disease.
Question 8:
A 40-year-old woman describes intermittent crampy abdominal pain and
bloating. She has constipation-predominant IBS based on prior evaluation.
Which lifestyle recommendation is MOST appropriate to include in her
management?
A) Strict fasting on one day per week
B) High-fat, low-fiber diet
C) Adequate dietary fiber and fluid intake
D) Avoid all physical activity
