I would want a different response from the vet. I don't know of any first time owners that could properly deal with such an injury. Call someone else.
If the injury is less than 24 hours old, you should try to get it stitch up. If you don't, you will have months of wrapping the leg and most likely be left will a disfiguring scar. Properly wrapping the leg is equally important. Start by covering the wound with a sterile gauze dressing. Hold it in place with gauze wrap. Add a cotton wrap. Go from knee to fetlock. Gauze wrap again than finish with vetwrap or elastikon. If you run elastikon around the top and bottom of the wrap (catch the skin/hair) it will stay in place for days. A poorly wrapped leg can do more damage than good. Getting the proper amount of tension on each layer comes with lots of experience.
It's important to limit all her activity. Lock her up in a stall if you can or make a small 10x10 panel pen for her. You want to limit the movement of the knee so she's not tearing anything as it heals. Take any grain away so she's not climbing the walls. Keep hay in front of her to help keep her out of trouble. Don't feel sorry for her and try to handwalk her. She'll quickly turn into a blooming idiot from lack of turnout and if she gets away from you, weeks of healing will be undone in about 10 seconds. You can easily be looking at 2 months or more to heal depending upon the severity of the injury. You can't rush it and I can't overemphasize it, she can't go out until the leg can withstand normal bucking and running.
Pen is administer I M. Your vet needs to show you how to give the shots and what the dosage is for her weight. A little bit of pain meds (bute) isn't a bad idea but it's rX so you can only get it from the vet and some pain is good. The pain will help keep her from moving around too much.
