Question

question 1
what is the first step when using direct pressure to control life - threatening bleeding?
call 9 - 1 - 1
apply a tourniquet
apply a dressing to the wound
check the scene for safety, form an initial impression, and obtain consent
question 2
when should you call 9 - 1 - 1 during a bleeding emergency?
after applying a roller bandage
immediately after checking the scene for safety
only if the bleeding does not stop after applying pressure
after controlling the bleeding

Explanation:

For Question 1: In first - aid for life - threatening bleeding, ensuring personal and victim safety (checking scene safety), forming an initial impression of the situation, and obtaining consent (if the victim is conscious) are fundamental before any other steps like applying dressings or tourniquets. Calling 9 - 1 - 1 is important but not the very first step in the sequence of actions related to direct pressure application process (the overall process starts with scene safety etc.).
For Question 2: In a bleeding emergency, once you have checked the scene for safety (to ensure you can safely help the victim), you should call 9 - 1 - 1 immediately. You don't wait until after applying a bandage, after controlling bleeding (as you may not be able to), or only if pressure fails (as the situation could deteriorate in the meantime).

Answer:

Question 1: Check the scene for safety, form an initial impression, and obtain consent
Question 2: Immediately after checking the scene for safety
