First Aid Bleeding and Wound Care 4

Question 1

A tourniquet has been applied. How should you mark time of application?

Accepted Answer

Write the time on the patient's skin near the tourniquet with a marker

Answer

Writing 'TK' and the time directly on the patient's skin ensures EMS always has the critical information even if rescuers change.

Question 2

What is the maximum recommended time a tourniquet should remain on a limb before tissue damage becomes a serious concern?

Accepted Answer

2 hours

Answer

Tourniquets should be removed or reassessed within approximately 2 hours to minimize risk of permanent nerve and tissue damage.

Question 3

During wound irrigation, what is the recommended minimum volume of clean water to use for a contaminated wound?

Accepted Answer

At least 250–500 mL or more

Answer

Copious irrigation with at least 250–500 mL of clean water significantly reduces bacterial contamination and infection risk.

Question 4

A patient is showing signs of hypovolemic shock from blood loss. Which combination of signs is most consistent with this condition?

Accepted Answer

Rapid weak pulse, low blood pressure, pale cool clammy skin

Answer

Hypovolemic shock causes compensatory tachycardia, hypotension, and peripheral vasoconstriction resulting in pale, cool, clammy skin.

Question 5

Which wound type is MOST likely to require sutures or wound closure strips to heal properly?

Accepted Answer

A deep 2-inch laceration on the scalp

Answer

Deep lacerations with gaping edges require closure to approximate tissue, reduce infection risk, and minimize scarring.
