How should you indicate that a casualty has received a tourniquet?

• A. Tie a knot in the bracelet
• B. Mark forehead with a T and the time applied
• C. Write on the casualty's clothing
• D. Shout that a tourniquet was used

Answer: (B)

The main idea is to clearly communicate that a tourniquet has been placed and when it was applied. Marking a “T” with the time on the casualty’s forehead provides a visible, durable cue for every responder who treats or transports them. This quick, persistent marker tells medical teams not only that a tourniquet is present but also how long it has been in place, which is crucial for ongoing assessment and decision-making about reassessment and potential removal. The forehead is a convenient spot because it remains visible during initial and ongoing checks, even if other clothing changes occur. Other methods are less reliable: tying a knot in jewelry can be missed or loosen; writing on clothing can smear or wash off; shouting that a tourniquet was used doesn’t give a lasting, portable record for responders. Marking with a T and the time is the most practical, consistent approach.
