What is the most important thing to do when applying a tourniquet?

• A. Write down the time you applied it
• B. Apply as tight as possible
• C. Check for a pulse below the tourniquet
• D. Use a cloth as a pad

Answer: (A)

The critical point when a tourniquet is applied is to note exactly when you did it. That timestamp is essential because it tells medical personnel how long the limb has been without blood flow, which directly influences decisions about further treatment and the urgency of transport. Knowing the ischemia duration helps determine potential risks of tissue damage and guides how aggressively clinicians will intervene. While tightening enough to stop the bleeding is important, and other steps like checking distal pulses or padding can be part of care, recording the application time provides the most actionable information for ongoing management.
