Chest X-ray shows right lower lobe consolidation. Most likely diagnosis?
A) Pneumonia
B) Pulmonary embolism
C) Asthma exacerbation
D) Bronchitis
Answer: A) Pneumonia
Rationale: Fever, productive cough, and radiographic consolidation indicate
bacterial pneumonia.
2.
A patient presents with palpitations, diaphoresis, and anxiety. ECG shows
narrow complex tachycardia at 180 bpm. First-line management?
A) Adenosine
B) Amiodarone
C) Metoprolol
D) Digoxin
Answer: A) Adenosine
Rationale: Adenosine is first-line for acute termination of supraventricular
tachycardia (SVT).
,3.
A patient presents with fatigue, pallor, and spoon-shaped nails. Labs reveal low
hemoglobin and low ferritin. Diagnosis?
A) Iron deficiency anemia
B) Vitamin B12 deficiency
C) Hemolytic anemia
D) Thalassemia
Answer: A) Iron deficiency anemia
Rationale: Low ferritin and characteristic physical signs indicate iron-deficiency
anemia.
4.
Which of the following lab values is most specific for acute myocardial
infarction?
A) CK-MB
B) Troponin I/T
C) BNP
D) ALT
Answer: B) Troponin I/T
Rationale: Troponin is highly specific for myocardial injury and remains elevated
for several days.
5.
A patient presents with progressive dyspnea and dry cough. HRCT shows
honeycombing and interstitial fibrosis. Most likely diagnosis?
A) Asthma
B) COPD
C) Idiopathic pulmonary fibrosis
D) Pneumonia
,Answer: C) Idiopathic pulmonary fibrosis
Rationale: Honeycombing on HRCT is characteristic of interstitial lung disease,
especially IPF.
6.
Which of the following medications is first-line for type 2 diabetes mellitus?
A) Insulin
B) Metformin
C) Sulfonylurea
D) GLP-1 receptor agonist
Answer: B) Metformin
Rationale: Metformin improves insulin sensitivity and reduces hepatic glucose
production.
7.
A patient presents with sudden-onset severe right upper quadrant pain, nausea,
and vomiting. Murphy’s sign is positive. Most likely diagnosis?
A) Cholecystitis
B) Appendicitis
C) Pancreatitis
D) Hepatitis
Answer: A) Cholecystitis
Rationale: RUQ pain, nausea, vomiting, and positive Murphy’s sign indicate acute
cholecystitis.
, 8.
Which of the following electrolyte disturbances is most commonly associated
with Addison’s disease?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypocalcemia
Answer: A) Hyperkalemia
Rationale: Aldosterone deficiency leads to potassium retention in Addison’s
disease.
9.
A patient presents with fatigue, cold intolerance, and weight gain. Labs: TSH 18
µIU/mL, T4 low. Diagnosis?
A) Hyperthyroidism
B) Primary hypothyroidism
C) Secondary hypothyroidism
D) Subclinical hypothyroidism
Answer: B) Primary hypothyroidism
Rationale: Elevated TSH and low T4 indicate primary thyroid failure.
10.
Which of the following medications is first-line for chronic HFrEF?
