E) Rivaroxaban

Explanations & Answers:

Question Easy Answer:
B) Iron deficiency anaemia

Question Easy Explanation:
The patient presents with microcytic anaemia (MCV of 70 fL). The most common cause of microcytic anaemia, particularly in young adults, is iron deficiency. Signs like fatigue, shortness of breath, and pallor align with this diagnosis according to NICE guidelines.

Question Medium Answer:
C) Acute limb ischaemia

Question Medium Explanation:
Acute limb ischaemia is characterised by the “6 Ps”: Pain, Pallor, Pulselessness, Paresthesia, Paralysis, and “Perishing cold”. The sudden onset and progression of symptoms are consistent with an embolic event causing acute ischaemia, a vascular emergency.

Question Hard Answer:
C) Prothrombin complex concentrate

Question Hard Explanation:
In the case of warfarin-associated bleeding with a high INR, the immediate management is to reverse anticoagulation. Prothrombin complex concentrate is recommended by the BNF and NHS guidelines for rapid reversal of warfarin in life-threatening bleeding as it acts faster than vitamin K.

Medical fact of the day:
Did you know that aspirin, at low doses, is an antiplatelet agent and is used in the UK not only for pain and fever but also for the prevention of cardiovascular events due to its effect on inhibiting platelet aggregation?
