First Aid Bleeding, Wounds, and Shock Questions and Answers — Questions and Answers
Question 1: A person has a deep cut on their forearm that is spurting bright red blood. After ensuring the scene is safe and wearing personal protective equipment, what is your IMMEDIATE priority?
- Elevate the arm above the heart.
- Apply firm, direct pressure to the wound with a clean dressing. (Correct answer)
- Locate and apply pressure to the brachial artery pressure point.
- Cover the person with a blanket to prevent shock.
Correct answer: Apply firm, direct pressure to the wound with a clean dressing.
For arterial bleeding, characterized by spurting, bright red blood, the most critical and immediate action is to apply firm, direct pressure to the wound. This is the most effective way to control severe bleeding. While other steps like elevation and treating for shock are important, they are secondary to stopping the blood loss at its source.
Question 2: You are providing first aid to a construction worker who has a piece of rebar impaled through their thigh. The person is conscious and in pain. Which of the following actions is most appropriate?
- Carefully remove the rebar to clean and dress the wound.
- Apply direct pressure on top of the rebar to stop the bleeding.
- Shorten the rebar by breaking or cutting it for easier transport.
- Stabilize the rebar in place with bulky dressings and call for emergency help. (Correct answer)
Correct answer: Stabilize the rebar in place with bulky dressings and call for emergency help.
An impaled object should not be removed, as it may be acting as a plug to control bleeding and its removal can cause further significant damage. The correct procedure is to stabilize the object in place using bulky dressings to prevent movement, control bleeding by applying pressure around the object, and immediately seek emergency medical services.
Question 3: Which of the following are common signs and symptoms of shock?
- Flushed, warm skin, and a slow, bounding pulse.
- High blood pressure, agitation, and thirst.
- Pale, cool, clammy skin, and a rapid, weak pulse. (Correct answer)
- Deep, slow breathing and normal mental status.
Correct answer: Pale, cool, clammy skin, and a rapid, weak pulse.
The body's response to shock involves redirecting blood flow to vital organs. This results in pale or ashen, cool, and clammy (moist) skin. The heart beats faster to compensate for the loss of blood volume or pressure, leading to a rapid and weak pulse. Other signs include rapid, shallow breathing, nausea, and changes in mental status.
Question 4: A person has caught their hand in a piece of machinery, resulting in an avulsion, where a flap of skin is torn away but still partially attached. How should you care for the wound after controlling the bleeding?
- Cut off the skin flap to create a neat wound edge.
- Apply an ice pack directly to the torn tissue.
- Gently clean the wound, fold the skin flap back into its normal position, and cover with a sterile dressing. (Correct answer)
- Scrub the wound vigorously with an antiseptic solution.
Correct answer: Gently clean the wound, fold the skin flap back into its normal position, and cover with a sterile dressing.
For an avulsion where a skin flap is present, the proper first aid is to gently clean the wound area (e.g., with mild soap and water), carefully place the flap back into its normal position if possible, and cover it with a sterile dressing to protect it. This preserves the tissue for potential reattachment and healing. Aggressive cleaning or removing the tissue can cause further damage.
Question 5: A person is showing signs of shock after a serious fall. They are lying on their back and are conscious. After calling for emergency medical help, what is the best position for the person, assuming no head, neck, back, or leg injuries are suspected?
- Help them sit up with their back against a wall.
- Have them stand up and walk around slowly to improve circulation.
- Place them in a semi-seated position with knees bent.
- Have them continue to lie flat and elevate their legs about 12 inches. (Correct answer)
Correct answer: Have them continue to lie flat and elevate their legs about 12 inches.
For a person in shock without suspected spinal or leg injuries, elevating the legs helps to redirect blood flow from the extremities to the vital organs, such as the brain, heart, and lungs. They should be kept lying flat on their back. This position can help improve circulation and manage the symptoms of shock until emergency responders arrive.
Question 6: You are controlling severe bleeding from a wound on a person's arm with direct pressure and a dressing. If the blood soaks through the first dressing, what should you do?
- Remove the soaked dressing and apply a new one.
- Apply a tourniquet immediately above the wound.
- Apply a second dressing on top of the first one and continue to apply pressure. (Correct answer)
- Stop applying pressure and elevate the arm higher.
Correct answer: Apply a second dressing on top of the first one and continue to apply pressure.
If blood soaks through the initial dressing, you should not remove it, as this can dislodge any clots that have started to form and restart the bleeding. The correct procedure is to add another dressing or cloth pad on top of the first one and continue to maintain or even increase the pressure.
