Question

Why might you consider contacting medical direction before applying a tourniquet in the case of uncontrollable bleeding from an AV fistula?

A. The patient may be in danger of losing the limb.
B. Hemodialysis anticoagulants may make bleeding more severe.
C. Damage to the fistula may occur.
D. Medical direction should be contacted before any use of tourniquets by the EMT.

Answer 1

There are several reasons to contact medical direction before applying a tourniquet in the case of uncontrollable bleeding from an AV fistula. These reasons include the risk of limb loss, the effect of hemodialysis anticoagulants on bleeding, the potential damage to the fistula, and the importance of following safety protocols.

Step-by-step explanation:

When applying a tourniquet to control bleeding from an AV fistula, it is important to contact medical direction for several reasons:

1. The patient may be in danger of losing the limb: Tourniquets are used as a last resort to control severe bleeding. However, if applied incorrectly or for too long, they can cause limb ischemia and tissue damage. Medical direction can provide guidance on whether a tourniquet is appropriate and for how long it should be applied.
2. Hemodialysis anticoagulants: Patients with AV fistulas are often receiving hemodialysis treatment, which requires anticoagulants. These medications can make bleeding more severe, and medical direction can advise on the best approach to manage bleeding in these circumstances.
3. Potential damage to the fistula: AV fistulas are delicate structures that can be easily damaged. Applying a tourniquet without proper guidance could cause harm to the fistula and compromise its function. Medical direction can help determine the safest approach to control bleeding while minimizing harm to the fistula.
4. Overall safety: It is important to consult with medical direction before using any interventions, including tourniquets, to ensure patient safety and follow established protocols and guidelines.
