Abstract:
This document serves as a definitive study resource for the NR576 Differential Diagnosis in Adult-Gerontology
Primary Care final examination at Chamberlain University. It contains 200 meticulously verified multiple-choice
questions with correct answers and comprehensive rationales, covering the breadth of differential diagnosis in
adult and geriatric primary care. The content is organized by body system, reflecting the latest clinical practice
guidelines and diagnostic criteria for the 2026/2027 academic year. Each rationale elucidates the pathophysiology,
clinical reasoning, and key distinguishing features to solidify diagnostic skills. This resource is essential for
advanced practice nursing students aiming for a Grade A performance, as it aligns with course objectives and
emphasizes evidence-based, patient-centered care. The inclusion of geriatric-specific considerations ensures
applicability to the aging population, a core focus of adult-gerontology primary care. By mastering these

,Q1. A patient with a history of GERD reports progressive dysphagia and weight loss.
Barium swallow shows a smooth, tapered narrowing at the gastroesophageal
junction. What is the most likely diagnosis?
A. Esophageal adenocarcinoma
B. Benign esophageal stricture
C. Achalasia
D. Schatzki ring
Correct Answer: C. Achalasia
Rationale: Achalasia presents with dysphagia and weight loss, and barium swallow
classically shows a smooth, tapered 'bird's beak' narrowing at the gastroesophageal
junction due to failure of LES relaxation. Adenocarcinoma typically shows irregular
narrowing, benign stricture is associated with long-standing reflux but not weight loss,
and Schatzki ring is a mucosal ring at the gastroesophageal junction that causes
intermittent dysphagia without weight loss.
Why Wrong:
A - Adenocarcinoma usually presents with progressive dysphagia and irregular,
scalloped narrowing on barium swallow, not smooth tapering.
B - Benign peptic stricture also causes dysphagia but typically develops after years of
GERD and does not usually cause significant weight loss; barium swallow shows
smooth narrowing but not the classic 'bird's beak' pattern.
D - Schatzki ring is a thin mucosal ring associated with hiatal hernia and causes
intermittent dysphagia, not progressive weight loss.

Ch. 345.
Q2. A patient with long-standing hypertension and diabetes presents with acute onset
of flank pain and hematuria. CT abdomen without contrast shows a hyperdense mass
in the renal pelvis. Urine cytology is negative. What is the next best step?
A. Ureteroscopy with biopsy
B. MRI with gadolinium
C. Renal ultrasound with Doppler
D. Observation and repeat CT in 3 months
Correct Answer: A. Ureteroscopy with biopsy
Rationale: The CT finding of a hyperdense mass in the renal pelvis is concerning for
urothelial carcinoma, especially given hematuria and risk factors. Urine cytology can be
falsely negative. Ureteroscopy with biopsy provides definitive tissue diagnosis. MRI is not
superior for urothelial lesions, ultrasound may miss small pelvic masses, and observation
risks progression.
Page 3
, Why Wrong:
B - MRI with gadolinium is not first-line for evaluating a suspected renal pelvic mass;
CT urography or ureteroscopy is preferred.
C - Renal ultrasound with Doppler is useful for cystic versus solid renal masses but
has limited sensitivity for urothelial lesions in the renal pelvis.
D - Observation is inappropriate given the high suspicion for malignancy; delay could
allow progression.

50.
Q3. A patient with type 2 diabetes and stage 3 CKD is started on an SGLT2 inhibitor.
One week later, they present with fatigue, myalgias, and dark urine. Labs: eGFR 40,
urine dipstick positive for blood but no RBCs on microscopy. What is the most likely
cause?
A. Rhabdomyolysis inducing acute kidney injury
B. SGLT2 inhibitor-induced euglycemic DKA causing volume depletion
C. SGLT2 inhibitor-associated acute interstitial nephritis
D. SGLT2 inhibitor-associated sepsis from urinary tract infection
Correct Answer: A. Rhabdomyolysis inducing acute kidney injury
Rationale: Dark urine with positive dipstick for blood but no RBCs suggests
myoglobinuria due to rhabdomyolysis. SGLT2 inhibitors can rarely cause rhabdomyolysis,
especially in patients with CKD. Euglycemic DKA would present with nausea, vomiting,
and hyperventilation, not dark urine. Acute interstitial nephritis typically causes sterile
pyuria and WBC casts. Sepsis would include fever and bacteriuria.
Why Wrong:
B - Euglycemic DKA presents with nausea, vomiting, abdominal pain, and Kussmaul
breathing, not dark urine or myalgias.
C - Acute interstitial nephritis presents with fever, rash, eosinophilia, and white cell
casts on microscopy, not myoglobinuria.
D - Sepsis from UTI would cause fever, flank pain, and bacteriuria; urine dipstick
would show nitrites or leukocyte esterase.
Reference: Lehne, R. A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 48.
Q4. A patient presents with acute onset of vision loss in one eye associated with a
headache and tenderness over the temple. ESR is 100 mm/hr. Fundoscopic exam
shows a pale, swollen optic disc. What is the most likely diagnosis?
A. Central retinal artery occlusion
B. Anterior ischemic optic neuropathy (arteritic)
C. Optic neuritis
D. Papilledema due to pseudotumor cerebri
