What action should you take if someone with breathing problems has no medicine?

In a situation where someone is experiencing breathing problems and does not have any medicine available, the appropriate action to take is to call for emergency assistance. This is crucial because breathing difficulties can signify a serious medical condition, such as asthma, an allergic reaction, or even a heart problem. Prompt intervention is often necessary to prevent the situation from worsening.

Calling 911 ensures that trained medical professionals can arrive quickly to assess and treat the individual effectively. Immediate medical help is essential, as complications can arise quickly in cases of respiratory distress.

The other choices do not provide the appropriate level of care needed in such an emergency. For instance, waiting and watching can lead to a deterioration in the person's condition without any form of active support. Giving them water could potentially lead to choking, especially if they are struggling to breathe. Encouraging the person to breathe deeply might not be effective or safe, as they may not be able to follow that instruction due to their respiratory distress. Therefore, seeking emergency medical assistance is the best course of action in this scenario.
