OFA Wound Care & Bleeding Control — Questions and Answers
Question 1: What is the first step in controlling external bleeding?
- Apply a tourniquet immediately.
- Clean the wound with water.
- Apply direct pressure to the wound (Correct answer)
- Check for signs of infection.
Correct answer: Apply direct pressure to the wound
The most immediate and effective first step in controlling external bleeding is to apply firm, direct pressure directly onto the wound with a clean dressing or cloth. This pressure helps to compress the blood vessels and promote clotting, thereby reducing blood loss.
Question 2: When should you use a tourniquet?
- On all types of wounds.
- Only if bleeding continues after applying direct pressure (Correct answer)
- For minor cuts and scrapes.
- Immediately, regardless of wound severity.
Correct answer: Only if bleeding continues after applying direct pressure
A tourniquet is a last resort for severe, life-threatening bleeding that cannot be controlled by direct pressure or pressure bandages. It works by completely stopping blood flow to the limb, which can cause tissue damage, so it should only be used when other methods have failed and the bleeding poses an immediate threat to life.
Question 3: What is a sign of internal bleeding?
- Bruising, rapid pulse, and pale skin (Correct answer)
- Loud breathing and coughing.
- Itching and rash.
- Sneezing and nasal congestion.
Correct answer: Bruising, rapid pulse, and pale skin
Internal bleeding occurs when blood vessels inside the body are damaged, leading to blood loss within body cavities or tissues. Signs like bruising, a rapid and weak pulse (indicating the body's attempt to compensate for blood loss), and pale, cool, clammy skin (due to reduced blood volume and shock) are key indicators of internal hemorrhage.
Question 4: How should you treat a nosebleed?
- Lean the head back and breathe deeply.
- Lie flat and stay still.
- Lean forward and pinch the nostrils together (Correct answer)
- Apply a cold compress to the back.
Correct answer: Lean forward and pinch the nostrils together
To treat a nosebleed, the person should lean slightly forward to prevent blood from flowing down the throat, which can cause nausea or choking. Pinching the soft part of the nostrils together for 10-15 minutes applies direct pressure to the bleeding vessels, helping the blood to clot and stop the flow.
Question 5: Which of the following is NOT a recommended action for treating a minor wound?
- Clean with water and mild soap.
- Apply a clean dressing.
- Remove deeply embedded objects (Correct answer)
- Apply an antibiotic ointment.
Correct answer: Remove deeply embedded objects
For minor wounds, cleaning, dressing, and applying antibiotic ointment are appropriate steps. However, deeply embedded objects should never be removed by a first aid responder, as this can cause further damage, increased bleeding, or introduce infection. Such objects should be stabilized and left for medical professionals to remove.
Question 6: What is the purpose of elevating a bleeding limb?
- To increase circulation.
- To reduce swelling only.
- To reduce blood flow and help control bleeding (Correct answer)
- To check for broken bones.
Correct answer: To reduce blood flow and help control bleeding
Elevating a bleeding limb above the level of the heart uses gravity to reduce blood flow to the injured area. This decrease in hydrostatic pressure can help to slow down bleeding and make it easier for the body's clotting mechanisms to work effectively.
Question 7: How should you treat a puncture wound?
- Sew it closed immediately.
- Cover it tightly with thick gauze.
- Clean it and monitor for infection (Correct answer)
- Ignore it if bleeding is minimal.
Correct answer: Clean it and monitor for infection
Puncture wounds, while often appearing small, can be deep and carry a high risk of infection because they can introduce bacteria deep into tissues. The correct treatment involves thoroughly cleaning the wound with soap and water to remove contaminants and then closely monitoring for signs of infection, such as redness, swelling, pus, or increased pain.
Question 8: What should you do if bleeding soaks through the bandage?
- Remove the bandage and apply a new one.
- Apply more dressings on top and continue pressure (Correct answer)
- Wrap the wound tightly with tape.
- Do nothing and wait for it to stop.
Correct answer: Apply more dressings on top and continue pressure
If bleeding soaks through the initial bandage, it indicates that the pressure might not be sufficient or the bleeding is severe. The correct action is to apply additional clean dressings directly on top of the soaked ones and continue to apply firm, direct pressure. Removing the original bandage can disrupt the clotting process and worsen bleeding.
Question 9: What is a potential complication of untreated severe bleeding?
- Hypovolemic shock (Correct answer)
- High blood pressure.
- Allergic reaction.
- Broken bones.
Correct answer: Hypovolemic shock
Untreated severe bleeding leads to a significant loss of blood volume, which can result in hypovolemic shock. This life-threatening condition occurs when the heart can no longer pump enough blood to meet the body's needs, leading to organ damage and potentially death if not promptly addressed.
