Femoral nerve block: artery first, nerve next, then wrap it

Question 1Where does the femoral nerve lie in relation to the femoral artery at the inguinal crease?

1. aMedial to the femoral vein
2. bLateral to the artery, deep to fascia iliaca
3. cInside the femoral sheath with the artery
4. dSuperficial to fascia lata, over the artery

Question 2Why do you insert the needle from the lateral side?

1. aThe nerve is easier to see from the medial side
2. bIt gives a faster onset
3. cThe needle reaches the nerve before it can reach the artery
4. dThe lateral approach avoids fascia iliaca

Question 3Which area does a femoral nerve block not cover reliably?

1. aThe front of the thigh
2. bThe femoral shaft
3. cThe front of the knee
4. dThe skin on the outer side of the thigh

Question 4What does correct spread look like?

1. aFluid around the femoral vein
2. bDark fluid under fascia iliaca, surrounding the nerve
3. cFluid in the fat above fascia iliaca
4. dA swelling inside the nerve

Question 5What do you tell the patient and ward team after the block?

1. aThe block will last for 72 hours
2. bThe leg will be warm and red for a week
3. cThe patient can walk straight away
4. dThe thigh muscles will be weak, so the patient must not walk on the leg until the block wears off
