How does a nurse assess perfusion to the foot when a patient has a cast from the left middle calf to the toes?

Assess capillary refill of the left toes

Explanation:

Foot perfusion assessment helps to manage patients with diabetic foot ulceration to know if injuries on the foot could heal or if it needed to be amputated. Capillary refill time of the left foot helps to ascertain the time it would take for normal color to return to the toe after pressure had been applied. It helps to assess the level of illness and the level of blood circulation in the patient.

sadly i believe the answer is d

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
