Question Easy:
A 55-year-old man with a history of hypertension and smoking presents with chest pain radiating to his left arm. His ECG shows ST-elevation in leads II, III, and aVF. Which coronary artery is most likely occluded? 🚑

A) Left anterior descending artery
B) Left circumflex artery
C) Right coronary artery
D) Diagonal artery
E) Marginal artery

Question Medium:
A 46-year-old woman presents with progressive shortness of breath, a dry cough, and clubbing of her fingers. A high-resolution CT scan of the chest demonstrates a ‘ground glass’ appearance. What is the most likely diagnosis?

A) Pulmonary fibrosis
B) Chronic obstructive pulmonary disease (COPD)
C) Lung cancer
D) Pneumonia
E) Asthma

Question Hard:
A 65-year-old patient with a known history of atrial fibrillation presents to the emergency department after feeling lightheaded and experiencing palpitations. On examination, he is hypotensive with a blood pressure of 80/50 mmHg and has signs of heart failure. The ECG shows a regular wide complex tachycardia. Which is the most appropriate initial management? 🚨

A) Intravenous amiodarone
B) Synchronized cardioversion
C) Carotid sinus massage
D) Intravenous adenosine
E) Oral digoxin

Explanations & Answers:

Question Easy Answer: C
Question Easy Explanation: The presence of ST-elevation in leads II, III, and aVF indicates an inferior myocardial infarction, most commonly due to occlusion of the right coronary artery (RCA). Standard UK guidelines agree with this concise diagnostic approach in STEMI cases.

Question Medium Answer: A
Question Medium Explanation: Progressive shortness of breath, dry cough, finger clubbing, and a ‘ground glass’ appearance on a high-resolution CT scan are indicative of pulmonary fibrosis. NICE guidelines emphasize these findings for diagnosis.

Question Hard Answer: B
Question Hard Explanation: For a patient in shock with hypotension and signs of heart failure with a regular wide complex tachycardia, immediate synchronized cardioversion is recommended as per current UK guidelines to restore normal rhythm and address hemodynamic instability.

Medical fact of the day: Did you know that in the UK, chronic obstructive pulmonary disease (COPD) diagnosis and management improvements have significantly reduced hospital admissions over the past decade? This showcases the importance of implementing effective public health strategies and guidelines.
