Final answer:
To manage life-threatening bleeding in a toddler, one should apply direct pressure to the wound after calling 9-1-1, using a clean cloth or bandage, and maintain this pressure until EMS arrives.
Step-by-step explanation:
After calling 9-1-1, the appropriate care for a 14-month-old toddler with life-threatening bleeding from a wound on her upper arm is to apply direct pressure to stop the bleeding. Applying a tourniquet is generally recommended as a last resort and should be done by someone trained in its application to avoid further injury. The goal is to maintain pressure until EMS arrives, being cautious not to cause additional harm to the child.
When dealing with severe bleeding, it is essential to act quickly to reduce blood loss. The immediate response should be to control the bleeding with direct pressure, which is the most effective and immediate method to manage bleeding. Using clean cloth or bandage, press firmly against the wound. If the cloth becomes soaked with blood, do not remove it; instead, add more layers on top and continue to apply pressure.
A bandage can be applied to keep the pressure consistently applied. Throughout the process, it is important to also keep the child calm and reassured until professional help arrives.
