mother treating daughter's injured knee with first-aid kit

A well-stocked first-aid kit can help you respond effectively to common injuries and emergencies. Lea Mathison, BSN, RN, the emergency department trauma coordinator at MercyOne Siouxland Medical Center, breaks down best practices and essentials for your first-aid kit.

First-aid kit basics

A few basics to be aware of when creating your first-aid kit include:

  • Keep at least one-first aid kit in your home or in your car
  • Make sure to store your kits in a place easy to get to and out of the reach of children
  • Talk with your children that are old enough about the purpose of the kits and where they are located

Additional considerations:

Aspirin is something you can consider having in a first-aid kit for the purpose of someone having chest pain that is unexplainable.

However, do not take aspirin if you are allergic to aspirin, have bleeding problems, take blood thinners, or advised by your provider not to do so. Never give children aspirin.

Emergency items:

  • Emergency phone numbers including contact information for your family health care provider and pediatrician, local emergency services, emergency road service providers and the poison help line.
  • Contact poison help line for help Poison Control in the U.S.: online at www.poison.org or by calling 1-800-222-1222. Both options are free, confidential, and available 24 hours a day.
