When someone has an accident, we use different words to say if something is necessary, forbidden, or just good advice.
1. Advice: Should and Shouldn't
Use these when you want to give a helpful suggestion or an opinion. It’s not a strict rule, but it’s the right 
thing to do.
- Should: "You should lie down if you feel dizzy."
- Shouldn't: "You shouldn't play football if you hurt your ankle."
2. Strong Necessity: Must and Need to
Use these when it is very important or essential to do something.
- Must: "You must call an ambulance if the accident is serious!"
- Need to: "You need to take some medicine for that pain."
3. Prohibition & No Necessity: Mustn't and Don't need to
These have very different meanings! Be careful:
- Mustn't (Prohibition): It is necessary that you do NOT do something.
- Example: "You mustn't touch a burn with dirty hands."
- Don't need to (Lack of necessity): It is not necessary to do it, but you can if you want.
- Example: "You don't need to go to the hospital for a small cut on your finger.
