Question Easy: 🚑 A 62-year-old man with a history of chronic obstructive pulmonary disease (COPD) presents with increased breathlessness. Which of the following is the most appropriate initial management?
A) Start oral antibiotics
B) Provide supplemental oxygen
C) Initiate nebulised salbutamol
D) Prescribe systemic steroids
E) Arrange for pulmonary rehabilitation
Explanations & Answers:
Question Easy Answer: C) Initiate nebulised salbutamol
Question Easy Explanation: In patients with COPD experiencing an exacerbation characterised by increased breathlessness, NICE guidelines recommend the use of a short-acting bronchodilator, such as nebulised salbutamol, as the initial management step. Supplemental oxygen may be appropriate, but it requires careful monitoring of oxygen saturation to avoid CO2 retention.
Question Medium: ❓ A 45-year-old woman complains of palpitations. She has no significant past medical history, and an ECG shows a regular narrow-complex tachycardia. What is the most appropriate immediate management?
A) Digoxin
B) Carotid sinus massage
C) Amiodarone
D) Adenosine
E) Verapamil
Question Medium Answer: D) Adenosine
Question Medium Explanation: For a patient with paroxysmal supraventricular tachycardia (SVT), the immediate management of a regular narrow-complex tachycardia is the use of adenosine. Adenosine transiently blocks the atrioventricular (AV) node, allowing the heart to return to a normal rhythm. Carotid sinus massage is an option, but adenosine is typically preferred due to its reliability and ease of administration.
Question Hard: 🧐 A 28-year-old marathon runner collapses during a race. On examination, a late systolic click and a murmur are heard. The ECG shows non-specific T-wave changes. What is the most likely diagnosis?
A) Aortic stenosis
B) Mitral valve prolapse
C) Hypertrophic cardiomyopathy
D) Atrial septal defect
E) Long QT syndrome
Question Hard Answer: B) Mitral valve prolapse
Question Hard Explanation: The presence of a late systolic click and murmur is suggestive of mitral valve prolapse (MVP). MVP can be seen in young athletes and may lead to non-specific ECG changes, such as T-wave abnormalities. Although collapse during physical activity requires prompt investigation, the clinical findings point towards MVP in this case.
Medical fact of the day: Did you know that the UK has one of the highest rates of COPD in Europe? Smoking is the most significant risk factor, and efforts to reduce smoking rates through NHS programs have been crucial in managing this disease.
