Question

1. what is the correct first step to stop a nosebleed? sit up straight and lean slightly forward. blow your nose to clear clots. tilt your head back and lie down. pinch the bridge of your nose. 11. how long should you pinch your nose to stop a nosebleed? 10 - 15 minutes. 5 minutes. 1 - 2 minutes. until the bleeding stops completely. 12. when should you seek medical attention for a nosebleed? if it happens during physical activity. if the nosebleed happens indoors. if it stops within 10 minutes. if it lasts longer than 20 minutes or follows a head injury.

Explanation:

• For question 10: Sitting up straight and leaning slightly forward is the correct first step. Blowing the nose can disrupt clotting, tilting the head back can cause blood to flow down the throat, and pinching the bridge of the nose is not the first step (the correct pinching area is lower).
• For question 11: Pinching the nose for 10 - 15 minutes is the recommended time. 5 minutes or 1 - 2 minutes may not be enough, and "until the bleeding stops completely" is not a specific time guideline as sometimes it needs a set duration of pressure.
• For question 12: Seeking medical attention if it lasts longer than 20 minutes or follows a head injury is correct. Nosebleeds during physical activity or indoors are common and not necessarily a reason for immediate medical attention if they stop within a reasonable time (not just 10 minutes as in some cases a bit longer but not 20+ is okay without head injury).

Answer:

1. Sit up straight and lean slightly forward.
2. 10 - 15 minutes.
3. If it lasts longer than 20 minutes or follows a head injury.
