The answer is the second one (B): A small child whose palm is burned by hot water.
Explanation for each option:
A. A teenager who has sunburned arms and is in pain: While sunburn can be painful, it is generally not a life-threatening emergency that requires calling 9-1-1. Sunburns can often be treated with home care, such as applying aloe vera or taking pain relievers.
B. A small child whose palm is burned by hot water: This situation is more serious because it involves a child and a burn from hot water, which can cause significant damage to the skin and underlying tissues. Burns in children can be more severe due to their sensitive skin and smaller body size, and they may require immediate medical attention. Therefore, calling 9-1-1 or the designated emergency number is appropriate.
C. A healthy adult who has a burn on the arm from a cigarette: A cigarette burn on the arm of a healthy adult is typically a minor injury that can be treated with basic first aid. It does not usually require emergency services unless there are complications or the burn is more severe than it appears.
D. An older person who has a small superficial burn on the leg: A small superficial burn is generally not life-threatening and can be managed with first aid. However, if the person has underlying health conditions or if the burn becomes infected, medical attention may be needed, but it does not typically require an emergency call.
In summary, the situation involving a small child with a burn from hot water is the most appropriate scenario to call 9-1-1 due to the potential severity and the need for immediate medical evaluation.
