Correct answer: B — Femoral and lateral femoral cutaneous nerves
Fascia iliaca block commonly covers femoral and lateral femoral cutaneous nerves. Femoral nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Ligamentum flavum is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Ulnar nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Intercostobrachial nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. In Primary FRCA anatomy, the tested structure should explain the block, airway sign or regional complication in the stem.
