Introduction
This comprehensive practice examination is meticulously designed to assess the advanced clinical knowledge
and diagnostic reasoning required for success in NU 518 Exam 2. The assessment rigorously evaluates the
student's mastery over advanced health assessment techniques, differential diagnosis formulation, evidence-
based pharmacological interventions, and the integration of pathophysiology into clinical decision-making.
Structured with 200 multiple-choice questions divided into two sections, this exam emphasizes real-world
patient scenarios, critical thinking, and the application of current clinical guidelines. Each question is followed
by a clear, detailed rationale to reinforce learning and ensure a thorough understanding of key principles. This
document serves as a definitive tool for final preparation, mirroring the complexity and depth of the official
examination.
,SECTION ONE: QUESTIONS 1 – 100
1. A 58-year-old male with a 30-pack-year smoking history presents with a new-onset cough, hemoptysis,
and weight loss. Which of the following is the MOST appropriate initial diagnostic test?
A. Chest X-ray
B. CT scan of the chest with contrast
C. Sputum cytology
D. Bronchoscopy with biopsy
🟢A
🔴 Explanation: A chest X-ray is the most appropriate initial imaging study for a patient presenting with
cough, hemoptysis, and weight loss, especially with a significant smoking history. It is readily available, cost-
effective, and can reveal masses, nodules, or other abnormalities that would guide further testing. CT scan,
sputum cytology, and bronchoscopy are subsequent steps if the initial X-ray is suspicious or if there is a high
clinical suspicion despite a normal X-ray.
2. A 72-year-old female with a history of hypertension and type 2 diabetes presents with complaints of
dizziness and lightheadedness upon standing. Her blood pressure is 142/88 mmHg while sitting and
112/70 mmHg upon standing. Which of the following is the MOST likely diagnosis?
A. Orthostatic hypotension
B. Hypertensive urgency
C. Vasovagal syncope
D. Carotid sinus hypersensitivity
🟢A
,🔴 Explanation: Orthostatic hypotension is defined as a drop in systolic blood pressure of ≥20 mmHg or a
drop in diastolic blood pressure of ≥10 mmHg within 3 minutes of standing. This patient meets the criteria,
and her symptoms are classic for orthostatic hypotension. Hypertensive urgency would present with severely
elevated BP without acute end-organ damage. Vasovagal syncope is typically preceded by a trigger and
involves a more pronounced drop in heart rate.
3. A 45-year-old female presents with a 6-month history of fatigue, joint pain, and a malar rash.
Laboratory findings reveal positive antinuclear antibodies (ANA) and anti-dsDNA antibodies. Which of the
following is the MOST appropriate next step in management?
A. Prescribe hydroxychloroquine
B. Refer to rheumatology
C. Order a complete blood count and urinalysis
D. Prescribe prednisone 20 mg daily
🟢B
🔴 Explanation: The presence of a malar rash, joint pain, positive ANA, and anti-dsDNA antibodies is highly
suggestive of systemic lupus erythematosus (SLE). The most appropriate next step is referral to a
rheumatologist for definitive diagnosis and management. While hydroxychloroquine and prednisone are
used in SLE, initiation should be guided by a specialist. Ordering a CBC and urinalysis is important, but it
should be done in conjunction with specialist referral.
4. A 60-year-old male with known coronary artery disease presents with worsening exertional chest pain
that is now occurring at rest. The pain is relieved by sublingual nitroglycerin. Which of the following is the
MOST appropriate diagnosis?
A. Unstable angina
B. Stable angina
C. Prinzmetal's angina
D. Myocardial infarction
, 🟢A
🔴 Explanation: This patient's chest pain has progressed to occur at rest, which classifies it as unstable
angina. Unstable angina is a medical emergency and represents an acute coronary syndrome. Stable angina
is predictable and occurs with exertion. Prinzmetal's angina is vasospastic and often occurs at rest but is not
typically associated with underlying coronary artery disease. Myocardial infarction would be diagnosed with
elevated cardiac biomarkers in addition to symptoms.
5. A 38-year-old pregnant woman at 28 weeks gestation presents with a headache, visual disturbances,
and epigastric pain. Her blood pressure is 168/102 mmHg. Urinalysis reveals 3+ protein. Which of the
following is the MOST appropriate immediate management?
A. Admit to the hospital for close monitoring and magnesium sulfate
B. Prescribe labetalol and send home with follow-up in 2 days
C. Schedule for induction of labor in 1 week
D. Prescribe acetaminophen for headache and recommend bed rest
🟢A
🔴 Explanation: This patient is presenting with preeclampsia with severe features, including severe
hypertension, headache, visual disturbances, epigastric pain, and proteinuria. The most appropriate
management is immediate hospitalization for close monitoring and administration of magnesium sulfate to
prevent eclampsia. This is a life-threatening condition that requires urgent intervention.
6. A 55-year-old male with a history of chronic alcohol use presents with confusion, ataxia, and
ophthalmoplegia. Which of the following is the MOST likely diagnosis?
A. Wernicke's encephalopathy
B. Korsakoff syndrome
C. Hepatic encephalopathy
D. Delirium tremens
