### Question 1
A 67-year-old patient with a history of hypertension and coronary artery disease presents with
progressive dyspnea on exertion, orthopnea, and paroxysmal nocturnal dyspnea. On physical
examination, you note jugular venous distention, hepatomegaly, and 3+ pitting edema in the lower
extremities. An S3 gallop is audible at the apex. Which hemodynamic parameter is most likely elevated
in this patient?
A. Left ventricular end-diastolic pressure
B. Right ventricular systolic pressure
C. Pulmonary artery wedge pressure
D. Central venous pressure
,💫RATIONALE✔️✔️: The patient's presentation of left-sided heart failure symptoms (dyspnea, orthopnea,
PND) combined with right-sided failure signs (JVD, hepatomegaly, edema) indicates biventricular failure.
The S3 gallop indicates elevated left ventricular end-diastolic pressure, reflecting poor left ventricular
compliance and volume overload. While pulmonary artery wedge pressure (C) would be elevated, LVEDP
is the direct measure of left ventricular filling pressure. Central venous pressure (D) reflects right-sided
pressures.
💫ANSWER✔️✔️: A. Left ventricular end-diastolic pressure

### Question 2
A 45-year-old patient presents with episodic headaches, palpitations, diaphoresis, and severe
hypertension. During an episode, blood pressure is 210/115 mmHg with tachycardia. Between episodes,
the patient is normotensive. Which diagnostic test would most likely confirm the suspected diagnosis?
A. 24-hour urine collection for metanephrines and catecholamines
B. Serum aldosterone-to-renin ratio
C. Overnight dexamethasone suppression test
D. Serum cortisol level at 8 AM
💫RATIONALE✔️✔️: The patient's presentation of episodic hypertension with headache, palpitations, and
diaphoresis is classic for pheochromocytoma, a catecholamine-secreting tumor. The diagnostic test of
choice is a 24-hour urine collection for fractionated metanephrines and catecholamines, which will show
elevated levels during symptomatic episodes. Aldosterone-to-renin ratio (B) is used to diagnose primary
aldosteronism. Dexamethasone suppression (C) and cortisol levels (D) are used to diagnose Cushing's
syndrome.
💫ANSWER✔️✔️: A. 24-hour urine collection for metanephrines and catecholamines

,### Question 3
A 72-year-old patient with a history of smoking presents with a chronic cough, hemoptysis, and weight
loss. On physical examination, you note clubbing of the fingers and decreased breath sounds in the right
upper lobe. Chest imaging reveals a mass in the right upper lobe. Which cell type is most likely
associated with this presentation?
A. Squamous cell carcinoma
B. Small cell carcinoma
C. Adenocarcinoma
D. Large cell carcinoma
💫RATIONALE✔️✔️: Squamous cell carcinoma is the most common type of lung cancer associated with
smoking and typically presents as a central mass with cavitation. It is strongly associated with clubbing
and hypertrophic pulmonary osteoarthropathy. The central location (right upper lobe) and presence of
hemoptysis are characteristic. Small cell carcinoma (B) is also associated with smoking but tends to be
more central and associated with paraneoplastic syndromes. Adenocarcinoma (C) is more common in
non-smokers and tends to be peripheral.
💫ANSWER✔️✔️: A. Squamous cell carcinoma

### Question 4
During a cardiovascular assessment, you auscultate a systolic murmur that is best heard at the second
right intercostal space and radiates to the carotid arteries. The murmur is harsh and crescendo-
decrescendo in quality. Which valvular condition is most consistent with these findings?
A. Aortic stenosis
B. Pulmonic stenosis
C. Mitral regurgitation
, D. Aortic regurgitation
💫RATIONALE✔️✔️: A harsh, crescendo-decrescendo systolic murmur best heard at the second right
intercostal space with radiation to the carotids is classic for aortic stenosis. The murmur results from
turbulent flow across a narrowed aortic valve during systole. Pulmonic stenosis (B) is heard at the left
upper sternal border. Mitral regurgitation (C) is a holosystolic murmur heard at the apex. Aortic
regurgitation (D) is a diastolic murmur.
💫ANSWER✔️✔️: A. Aortic stenosis

### Question 5
A 38-year-old patient with a history of rheumatoid arthritis presents with progressive shortness of
breath, dry cough, and fatigue. On physical examination, you note fine inspiratory crackles at the lung
bases and digital clubbing. Which pulmonary complication of rheumatoid arthritis is most likely
responsible for these findings?
A. Interstitial lung disease with pulmonary fibrosis
B. Pleural effusion with restrictive lung disease
C. Pulmonary nodules with cavitation
D. Obliterative bronchiolitis with airflow obstruction
💫RATIONALE✔️✔️: Interstitial lung disease with pulmonary fibrosis is a common pulmonary
complication of rheumatoid arthritis, presenting with progressive dyspnea, dry cough, fine inspiratory
crackles, and clubbing. The pathophysiology involves immune-mediated inflammation and fibrosis of the
lung interstitium. Pleural effusion (B) would present with dullness to percussion. Pulmonary nodules (C)
are usually asymptomatic. Obliterative bronchiolitis (D) would present with obstructive symptoms and
wheezing.
💫ANSWER✔️✔️: A. Interstitial lung disease with pulmonary fibrosis
