Well, I have had quite a few more problems than that, but I agree with your basic sentiment.
I am overly prone to minor burn accidents. Not sure why, but has held true over the years. Splinters are another biggie for all of the family. Thorny type. Then blisters. Next, minor cuts and abrasions. So, cleaning and covering are the big basics for me.
Sutures and scapels are not DIY for me :-)
My Mtn bike accident story -
Went with a very competent rider (me, not as capable). He also has a Masters in Sports Medicine, team trainer, therapist, etc. So, I am thinking, "good hands" and all.
Rains all morning. Coming down some shale switchbacks, I go down and slice my lower leg on a nice shale shard. I make it to the bottom pretty muddy/dirty and very bleeding. My buddy is waiting.
We take a look, pulling the flap back and he says, "That's your tibia."
So, I am thinking good thing he's there!
He squirts it with a water bottle and tosses me a band aid. Geesh, I could do that. So, luckily we crossed the forest service road at the bottom and only had to ride halfway back to the truck when a horseback rider on the way to his trailer picked us up in his truck and took us to ours.
Spent quite a bit of time in the ER getting debrided and seven stitches. The worse part is my buddy gets to watch and give me a running comentary, telling me how many millimeters of tissue are being removed.
I certainly would have liked to have had a better kit than a bandana and clean towel at the truck. BTW, using a waterbottle that has been drank from is a bad idea. All kinds of nasties to include possible staph infection. Luckily it was cool and rainy and I had only drank from by hydration pack, so my waterbottle was untouched by my mouth. Oh, and I got even with my buddy. I sold him my mountain bike!
