The best answer I can give, as someone who is not in the nursing field, is that there will be a reduction in blood flow to the medial tarsal artery, or answer C. This is because the knife entered in the dorsum and is pretty close to the ankle.

The medial tarsal artery runs right through that part of the foot, and if it’s cut, the blood won’t flow further down the artery. You may see some spurting action if the wound is not properly cauterized or clotted to stop the bleeding.

Again, it’s an artery that has been cut, so the blood is still pumping through the body because of the heart. As it hits that area, it cannot finish the round and it spurts out of the artery.

Reduction of blood flow in the medial tarsal artery -reduction of blood flow in the medial tarsal artery occurs because it is a branch of the dorsalis pedis artery, which begins at the ankle joint as the continuation of the anterior tibial artery. the anterior tibial and peroneal arteries supply the peroneus longus muscle. the deep plantar arterial arch is formed mainly by the lateral plantar artery. blood pressure in the anterior tibial artery should be higher than normal. the arcuate artery should have a low blood pressure because it is a terminal branch of the dorsalis pedis artery.
