Question 1

What is the danger of using a rubber band or thin cord as a makeshift tourniquet?

Accepted Answer

It may cut into tissue and damage nerves and blood vessels without stopping deep arterial bleeding

Answer

Thin improvised tourniquets concentrate pressure on a small area, cutting into skin and nerves while failing to compress deep arteries adequately.

Question 2

A wound is described as having jagged, irregular edges with tissue damage around it. What type of wound is this?

Accepted Answer

Laceration

Answer

A laceration has irregular, torn edges caused by blunt or tearing force, in contrast to the clean edges of a surgical incision.

Question 3

What is the correct way to remove a ring from an injured finger that is beginning to swell?

Accepted Answer

Attempt removal before significant swelling occurs; if not possible, cut the ring and refer to medical care

Answer

Early removal before major swelling is preferable; if impossible, the ring must be cut to prevent a tourniquet effect that can compromise circulation.

Question 4

Which of the following is a sign of wound infection developing after initial first aid was given?

Accepted Answer

Increasing redness, warmth, swelling, and pus at the wound site 24–72 hours later

Answer

Signs of infection — redness, warmth, swelling, pus, and fever — typically develop 24–72 hours after injury and require medical evaluation.

Question 5

When using Personal Protective Equipment (PPE) while managing a bleeding wound, which item is the MOST critical barrier against bloodborne pathogen exposure?

Accepted Answer

Disposable nitrile or latex gloves

Answer

Gloves provide the primary barrier between the first aider's skin and the victim's blood, protecting against bloodborne pathogens such as HIV and hepatitis B.
