A 15-year-old patient complains of left ankle pain after being tackled while playing football. He asks the nurse what tests he needs to have to determine if he has a strain or a fracture. How should the nurse reply?
1) "You don't need an x-ray; I can tell by the way your ankle looks and feels whether you have a strain or fracture."
2) "Sprains, strains, and fractures have similar symptoms at first; you will need an x-ray of the joint to be certain."
3) "We will need to get a venous Doppler study to make sure that there is not a fracture."
4) "An arterial Doppler will show whether the blood flow is interrupted, which is common for fractures but not for strains."
