Question Easy:
A 68-year-old man visits his GP with complaints of leg swelling, fatigue, and breathlessness. On examination, his legs show pitting oedema. Which of the following conditions is most likely causing these symptoms?
A) Deep vein thrombosis
B) Varicose veins
C) Chronic heart failure
D) Peripheral artery disease
E) Lymphedema
Explanations & Answers:
Question Easy Answer: C) Chronic heart failure
Question Easy Explanation: The symptoms described, including leg swelling (oedema), fatigue, and breathlessness, are classic signs of chronic heart failure. According to NICE guidelines, the accumulation of fluid in tissues as well as tiredness and shortness of breath are indicative of this condition. Oedema in heart failure is due to fluid retention caused by the heart’s reduced ability to pump blood effectively.
Question Medium:
A 54-year-old woman presents to the emergency department with acute pain, swelling, and redness in her left calf. The symptoms started suddenly after a long-haul flight. What is the most appropriate first-line treatment for this condition?
A) Warfarin
B) Rivaroxaban
C) Aspirin
D) Compression stockings
E) Thrombolysis
Explanations & Answers:
Question Medium Answer: B) Rivaroxaban
Question Medium Explanation: The presentation is suggestive of deep vein thrombosis (DVT), often triggered by prolonged immobility, such as after a long-haul flight. NICE guidelines recommend rivaroxaban as a first-line treatment for DVT due to its oral administration, predictable pharmacokinetics, and reduced requirement for regular monitoring compared to warfarin.
Question Hard:
A 72-year-old man presents with a history of recurrent episodes of dizziness and syncope. On examination, he has a harsh systolic murmur best heard over the right second intercostal space and radiating to the carotids. His blood pressure is 110/70 mmHg. Which of the following is the most likely underlying diagnosis?
A) Mitral stenosis
B) Mitral regurgitation
C) Aortic stenosis
D) Hypertrophic cardiomyopathy
E) Aortic regurgitation
Explanations & Answers:
Question Hard Answer: C) Aortic stenosis
Question Hard Explanation: The clinical findings suggest aortic stenosis, characterized by a harsh systolic murmur heard over the aortic area and radiating to the carotids. The symptoms of dizziness and syncope, combined with the murmur, align with the pathophysiology of aortic stenosis, where the narrowed valve impedes blood flow from the left ventricle into the aorta, often leading to reduced cerebral perfusion, especially during exertion. This aligns with both NHS and NICE guidelines on the identification and management of valvular heart disease.
Medical fact of the day: 🌍 Did you know? In the UK, iron deficiency anaemia is one of the most common haematological disorders, and according to NICE guidelines, it’s crucial to investigate and manage the underlying cause, as it often reflects gastrointestinal blood loss in men and postmenopausal women.
