NR 511 CEA EXAM: COMPREHENSIVE CLINICAL EXAMINATION
WITH 150 QUESTIONS,CORRECT ANSWERS,WELL VERIFIED
AND ELABORATED RATIONALES!
Section 1: Cardiovascular & Respiratory (Questions 1-25)
1. A 68-year-old male with a history of hypertension and smoking presents with a non-healing ulcer on
his right great toe. His right foot is cool to the touch and has diminished hair growth. What is the most
likely diagnosis?
A. Venous stasis ulcer
B. Neuropathic ulcer
C. Arterial insufficiency ulcer
D. Pressure ulcer
Correct ANSWER: C. Arterial insufficiency ulcer
Rationale: Arterial insufficiency ulcers are typically located on the distal extremities (toes, feet) and are
characterized by a pale, "punched-out" appearance, cool skin temperature, and diminished hair growth
due to poor perfusion. Venous stasis ulcers (A) are usually medial malleolus, warm, and have irregular
borders. Neuropathic ulcers (B) are pressure-related, often on the plantar surface. Pressure ulcers (D)
occur over bony prominences.
2. A 55-year-old female with a history of CHF presents with progressive dyspnea, orthopnea, and
bilateral lower extremity edema. On auscultation, you hear bibasilar crackles and an S3 gallop. Which
medication is the most appropriate first-line therapy for managing her volume overload?
A. Metoprolol
B. Furosemide
C. Lisinopril
D. Spironolactone
Correct ANSWER: B. Furosemide
Rationale: Furosemide is a loop diuretic that is the mainstay of therapy for acute volume overload in
heart failure. It rapidly reduces preload, relieving symptoms of pulmonary congestion and edema.
Metoprolol (A) and Lisinopril (C) are chronic management medications that do not provide immediate
,relief of fluid overload. Spironolactone (D) is a potassium-sparing diuretic used in severe CHF but is not
the first-line for acute decompensation.
3. A 32-year-old healthy female is diagnosed with a urinary tract infection (UTI). Which antibiotic is
considered a first-line agent for uncomplicated cystitis?
A. Ciprofloxacin
B. Nitrofurantoin
C. Doxycycline
D. Amoxicillin
Correct ANSWER: B. Nitrofurantoin
Rationale: Nitrofurantoin is a first-line agent for uncomplicated cystitis due to its high efficacy and low
resistance rates among E. coli. Ciprofloxacin (A) is generally reserved for complicated UTIs due to
resistance concerns. Doxycycline (C) and Amoxicillin (D) are not first-line treatments for UTIs.
4. A patient presents with sudden onset of pleuritic chest pain and shortness of breath. Physical exam
reveals tachycardia and tachypnea. What is the most critical diagnostic test to order initially?
A. D-dimer
B. Chest X-ray
C. CT Pulmonary Angiography
D. V/Q Scan
Correct ANSWER: C. CT Pulmonary Angiography
Rationale: CT Pulmonary Angiography (CTPA) is the gold standard and most definitive test for diagnosing
a pulmonary embolism (PE), which is suspected here. While a D-dimer (A) is sensitive but not specific,
CTPA provides a definitive diagnosis if positive. Chest X-ray (B) is often normal in PE and used to rule out
other causes. V/Q Scan (D) is used when CTPA is contraindicated.
5. What ECG finding is most characteristic of an acute ST-segment elevation myocardial infarction
(STEMI)?
A. ST-segment depression
B. T-wave inversion
,C. ST-segment elevation in contiguous leads
D. Pathologic Q waves
Correct ANSWER: C. ST-segment elevation in contiguous leads
Rationale: ST-segment elevation in two or more contiguous leads is the hallmark of an acute STEMI and
indicates transmural ischemia. ST-segment depression (A) and T-wave inversion (B) are suggestive of
ischemia but not specific to STEMI. Pathologic Q waves (D) indicate a completed infarct and are not an
acute finding.
6. A 60-year-old male with a 20-pack-year smoking history presents with a chronic cough and
hemoptysis. A chest X-ray shows a suspicious nodule. What is the most likely diagnosis?
A. Tuberculosis
B. Bronchogenic carcinoma
C. Pneumonia
D. Pulmonary embolism
Correct ANSWER: B. Bronchogenic carcinoma
Rationale: A suspicious nodule in a patient with a significant smoking history and hemoptysis raises high
suspicion for bronchogenic carcinoma (lung cancer). Tuberculosis (A) presents with fever, night sweats,
and weight loss. Pneumonia (C) is acute with fever and productive cough. Pulmonary embolism (D) is an
acute onset of respiratory distress.
7. Which of the following is a known adverse effect of statin therapy?
A. Hyperglycemia
B. Hypokalemia
C. Sinus tachycardia
D. Constipation
Correct ANSWER: A. Hyperglycemia
Rationale: Statins are associated with a modest increase in blood glucose levels and an increased risk of
developing type 2 diabetes. They are also known for myalgias and elevated liver enzymes. They do not
cause hypokalemia (B), sinus tachycardia (C), or constipation (D) as primary adverse effects.
, 8. A patient with acute bronchitis is asking for antibiotics. Which of the following is the most appropriate
management for this patient?
A. Azithromycin
B. Amoxicillin-clavulanate
C. Symptom management and symptomatic relief
D. Levofloxacin
Correct ANSWER: C. Symptom management and symptomatic relief
Rationale: Acute bronchitis is typically viral in origin. Antibiotics (A, B, D) are not indicated unless there is
a secondary bacterial infection or a specific diagnosis like pertussis. Management focuses on supportive
care, including hydration, rest, and symptom relief (e.g., cough suppressants).
9. What is the most common cause of heart failure exacerbation?
A. Non-adherence to dietary restrictions
B. Medication non-compliance
C. Myocardial ischemia
D. Infection
Correct ANSWER: D. Infection
Rationale: While all options can contribute, the most common identifiable precipitating cause of acute
decompensated heart failure is infection, particularly pneumonia or urinary tract infections, which
increase metabolic demands and fluid requirements.
10. A patient presents with a blood pressure of 180/110 mmHg. They are asymptomatic. What is the
most appropriate next step?
A. Admit to the hospital for IV antihypertensives
B. Recheck blood pressure in 5 minutes and start oral antihypertensives
C. Order a CT scan of the head
D. Prescribe sublingual nifedipine
