The answer that best completes the statement above is this: POSTERIOR TIBIAL. Based on the nurse's assessment, stabbing pain and burning sensation is reported as the subjective cue and the skin of the foot is lighter. Given this result, this would clearly mean that the artery in the left foot is being occluded. And the artery present here is the posterior tibial artery. The stabbing pain and burning sensation being felt of the patient is a result of lack of oxygen in the area since the blood can no longer circulate.
I would tell their parents (hopefully they are good parents), but I would tell them to act as if they figured it out by themselves, so my friend won't know that I told them and won't hate me.
