Question

Blockade of all of the following combinations of nerves EXCEPT which one will provide adequate anesthesia for surgery of the entire foot?

A. Femoral, sciatic
B. Popliteal, saphenous
C. Sural, saphenous, deep peroneal, superfi cial peroneal, posterior tibial
D. Obturator, sciatic, sural, posterior tibial
E. Common peroneal, tibial, femoral

Answer 1

To provide adequate anesthesia for surgery of the entire foot, blockade of the femoral and sciatic nerves is necessary.

Step-by-step explanation:

To provide adequate anesthesia for surgery of the entire foot, a blockade of all the following combinations of nerves except one is required. The only combination that will provide adequate anesthesia for such surgery is A. Femoral and sciatic nerves. Blockade of the femoral and sciatic nerves will ensure complete anesthesia of the foot. The other options listed, such as B. Popliteal and saphenous nerves, C. Sural, saphenous, deep peroneal, superficial peroneal, and posterior tibial nerves, D. Obturator, sciatic, sural, and posterior tibial nerves, and E. Common peroneal, tibial, and femoral nerves, will not provide complete anesthesia for the entire foot.
