A) Amoxicillin
B) Nitrofurantoin
C) Ciprofloxacin
D) Azithromycin
E) Trimethoprim

Explanations & Answers:

Question Easy Answer: B
Question Easy Explanation: Iron deficiency anaemia is characterised by low serum ferritin levels, indicating depleted iron stores. Serum ferritin is a sensitive test for iron deficiency when the patient is otherwise healthy and there is no inflammation. This aligns with NICE guidelines, which recommend checking serum ferritin as part of the diagnosis of iron deficiency anaemia.

Question Medium Answer: C
Question Medium Explanation: The presentation of a pulsatile abdominal mass with severe abdominal pain in an older male with risk factors such as smoking and hypertension suggests an abdominal aortic aneurysm (AAA) rupture. According to NHS guidelines, AAA is a critical emergency, and immediate medical intervention is required.

Question Hard Answer: C
Question Hard Explanation: Ciprofloxacin can potentiate the effect of warfarin by altering its metabolism, which can increase the INR and the risk of bleeding. According to the BNF, interactions between warfarin and certain antibiotics, like ciprofloxacin, necessitate close monitoring of INR levels and possibly adjusting the warfarin dose.
