INTRODUCTION
This comprehensive test bank is designed for advanced practice nurse
students preparing for the NR 511 Midterm Examination in Differential
Diagnosis and Primary Care Practicum. It assesses foundational diagnostic
reasoning, evidence-based clinical decision-making, advanced history
taking, and systematic physical assessment across the lifespan. The test
bank employs multiple-choice and scenario-based questions that simulate
realistic primary care encounters. Emphasis is placed on critical thinking,
differential diagnosis, patient-centered communication, and the application
of current clinical guidelines. Three complete versions provide varied yet
equivalent assessments to support rigorous study and exam readiness.
VERSION A: QUESTIONS 1–100
(Version A was provided in the previous response. Please scroll up to
access the full Version A. Below are Versions B and C.)
VERSION B: QUESTIONS 1–50
,1. A 58-year-old male presents with a 3-month history of progressive
dyspnea on exertion and a dry, hacking cough. He has a 40-pack-year
smoking history. Which diagnosis is most likely?
A. Asthma
B. Chronic obstructive pulmonary disease (COPD)
C. Heart failure
D. Tuberculosis
B. Chronic obstructive pulmonary disease (COPD)
RATIONALE: Progressive dyspnea on exertion and a chronic dry cough
in a long-term smoker are classic for COPD. Asthma often has intermittent
symptoms and a history of atopy. Heart failure typically presents with
orthopnea and edema. Tuberculosis would include fever, night sweats, and
weight loss.
2. A 24-year-old female presents with a 2-day history of dysuria,
frequency, and urgency. She has no fever or flank pain. Which is the
most appropriate initial management?
A. Obtain a urine culture and start antibiotics
B. Recommend increased fluid intake and NSAIDs
C. Prescribe nitrofurantoin empirically
D. Refer to urology for cystoscopy
C. Prescribe nitrofurantoin empirically
RATIONALE: Uncomplicated cystitis in a young, non-pregnant female
can be treated empirically with nitrofurantoin. A urine culture is not routinely
required for first episodes. Increased fluids and NSAIDs are adjunctive but
not definitive.
3. A 45-year-old male with a history of hypertension and diabetes
presents with a BP of 158/94 mmHg. He is already on lisinopril 20 mg
daily. What is the most appropriate next step?
A. Add a thiazide diuretic
B. Increase lisinopril to 40 mg daily
,C. Add a beta-blocker
D. Refer to nephrology
A. Add a thiazide diuretic
RATIONALE: For patients with diabetes and hypertension not at goal
on an ACE inhibitor, adding a thiazide diuretic (e.g., chlorthalidone) is a
guideline-recommended step. Increasing lisinopril may not provide
additional benefit and could increase side effects.
4. A 68-year-old female presents with sudden onset of severe, tearing
chest pain radiating to her back. Her BP is 180/100 mmHg in the right
arm and 140/80 mmHg in the left arm. What is the priority action?
A. Administer morphine for pain
B. Obtain an ECG
C. Activate emergency services for suspected aortic dissection
D. Start a beta-blocker
C. Activate emergency services for suspected aortic dissection
RATIONALE: Tearing chest pain with a BP differential between arms is
classic for aortic dissection, a surgical emergency. Immediate transfer for
imaging and surgical evaluation is required.
5. A 32-year-old female presents with a 6-month history of fatigue,
weight gain, cold intolerance, and constipation. TSH is elevated, free
T4 is low. What is the most likely diagnosis?
A. Hyperthyroidism
B. Hypothyroidism
C. Cushing syndrome
D. Addison disease
B. Hypothyroidism
RATIONALE: Elevated TSH with low free T4 is diagnostic of primary
hypothyroidism. Symptoms include fatigue, weight gain, cold intolerance,
and constipation.
, 6. A 16-year-old male presents with a 2-week history of severe sore
throat, fever, and fatigue. Exam shows exudative pharyngitis,
posterior cervical lymphadenopathy, and splenomegaly. Heterophile
antibody test is positive. What is the diagnosis?
A. Streptococcal pharyngitis
B. Infectious mononucleosis
C. Acute leukemia
D. Diphtheria
B. Infectious mononucleosis
RATIONALE: Exudative pharyngitis, posterior cervical
lymphadenopathy, splenomegaly, and a positive heterophile antibody test
are diagnostic of infectious mononucleosis (Epstein-Barr virus).
7. A 70-year-old male presents with a 3-month history of progressive
dysphagia for solids and weight loss. He has a 30-pack-year smoking
history and daily alcohol use. What is the most likely diagnosis?
A. Achalasia
B. Esophageal carcinoma
C. GERD
D. Esophageal stricture
B. Esophageal carcinoma
RATIONALE: Progressive dysphagia for solids, weight loss, and
significant smoking/alcohol history are highly suspicious for esophageal
carcinoma.
8. A 28-year-old female presents with a 1-week history of palpitations,
heat intolerance, and weight loss. Exam reveals a diffusely enlarged,
non-tender thyroid and exophthalmos. What is the most likely
diagnosis?
A. Graves disease
B. Hashimoto thyroiditis
C. Toxic multinodular goiter
D. Thyroid carcinoma
