,Q1. A patient with type 2 diabetes and chronic kidney disease (eGFR 42
mL/min/1.73m2) has persistent albuminuria (UACR 350 mg/g) despite maximal ACE
inhibitor therapy. According to 2026 ADA guidelines, which add-on therapy is most
appropriate to slow CKD progression?
A. Finerenone
B. Dapagliflozin
C. Liraglutide
D. Irbesartan
Correct Answer: B. Dapagliflozin
Rationale: SGLT2 inhibitors (e.g., dapagliflozin) are now recommended for patients with
diabetic kidney disease and eGFR 25 mL/min/1.73m2, independent of metformin, to reduce
CKD progression and cardiovascular risk. Finerenone is an option but typically added
after SGLT2 inhibitor or if not tolerated. Liraglutide is for glycemic control, not
specifically for CKD progression, and irbesartan is already maximally dosed.
Why Wrong:
A - Finerenone is a second-line option after SGLT2 inhibitor or if SGLT2i not
tolerated, not the first add-on.
C - GLP-1 receptor agonists have cardiovascular benefit but are not specifically
preferred for CKD progression over SGLT2 inhibitors.
D - Irbesartan is an ARB; adding to maximal ACE inhibitor is not recommended due
to increased hyperkalemia risk without benefit.

Q2. A 55-year-old man presents with acute onset of severe, tearing chest pain
radiating to the back, and a blood pressure difference of 25 mmHg between arms.
Which imaging study is the most appropriate initial diagnostic test to confirm or
exclude aortic dissection?
A. Chest X-ray
B. Transthoracic echocardiogram
C. CT angiography of the chest
D. MRI of the chest
Correct Answer: C. CT angiography of the chest
Rationale: CT angiography (CTA) of the chest is the preferred initial imaging modality for
suspected aortic dissection due to its high sensitivity and specificity, rapid availability, and
ability to guide surgical planning. Chest X-ray may show mediastinal widening but is not
diagnostic. Transthoracic echocardiography has limited sensitivity for dissection, and MRI
is time-consuming and less accessible in emergencies.
Page 3
, Why Wrong:
A - Chest X-ray is insufficient to rule out dissection; it only provides indirect signs.
B - Transthoracic echocardiography has limited sensitivity for aortic dissection,
especially in stable patients.
D - MRI is less practical in acute settings due to time and availability issues.

Management of Aortic Disease. Circulation.
Q3. In a patient with newly diagnosed hypertension and a serum potassium of 3.2
mEq/L, which medication class is most likely to exacerbate the hypokalemia?
A. ACE inhibitors
B. Thiazide diuretics
C. Angiotensin II receptor blockers
D. Calcium channel blockers
Correct Answer: B. Thiazide diuretics
Rationale: Thiazide diuretics promote potassium and magnesium wasting, potentially
worsening hypokalemia. ACE inhibitors and ARBs typically cause potassium retention,
and calcium channel blockers have minimal effect on serum potassium.
Why Wrong:
A - ACE inhibitors increase potassium, not decrease.
C - ARBs also increase potassium.
D - Calcium channel blockers do not significantly affect potassium levels.

Detection, Evaluation, and Management of High Blood Pressure in Adults.
Hypertension.
Q4. A patient with stable COPD (FEV1 55% predicted) and moderate dyspnea
despite regular long-acting muscarinic antagonist (LAMA) therapy is being
considered for escalation. According to the 2026 GOLD strategy, which combination
is most appropriate as the next step?
A. Add inhaled corticosteroid (ICS) to LAMA
B. Switch to LAMA/LABA combination
C. Add theophylline
D. Add oral corticosteroids
Correct Answer: B. Switch to LAMA/LABA combination
Rationale: For patients with persistent dyspnea on LAMA monotherapy, the 2026 GOLD
guidelines recommend escalating to LAMA/LABA combination, which provides additional
bronchodilation and improves symptoms and exercise tolerance. ICS is reserved for
patients with exacerbations and eosinophilia. Theophylline is third-line, and oral
