What must NOT be done when someone is impaled by a foreign object?
- A.
Call 995 immediately.
- B.
Give constant assurances to the casualty.
- C.
Attempt to pull out the impaled object.
- D.
Do not give the casualty anything to eat or drink.
Correct Answer
C. Attempt to pull out the impaled object.Explanation
When someone is impaled by a foreign object, attempting to pull out the impaled object must not be done. Pulling out the object can cause further damage and increase bleeding. It is important to leave the object in place and seek immediate medical assistance by calling 995. Giving constant assurances to the casualty and not giving them anything to eat or drink are also important actions to take in this situation.Rate this question:

An arterial haemorrhage is characterized by ___________ .
- A.
Oozing of blood
- B.
Dark red deoxygenated blood
- C.
Profused gushing of dark red blood
- D.
Richly oxygenated blood that is bright red and spurting out
Correct Answer
D. Richly oxygenated blood that is bright red and spurting outExplanation
An arterial hemorrhage is characterized by richly oxygenated blood that is bright red and spurting out. Arteries carry oxygenated blood away from the heart to the rest of the body, so when an artery is damaged and bleeding, the blood that comes out is bright red and under pressure, causing it to spurt out. This is in contrast to veins, which carry deoxygenated blood back to the heart and are characterized by darker red blood that oozes rather than spurts.Rate this question:

In the case of an arterial haemorrhage from the thigh, you should apply pressure on the _____________________.
- A.
Carotid pressure point
- B.
Brachial pressure point
- C.
Femoral pressure point
- D.
Subclavian pressure point
Correct Answer
C. Femoral pressure pointExplanation
In the case of an arterial hemorrhage from the thigh, applying pressure on the femoral pressure point can help control the bleeding. The femoral artery is a major blood vessel located in the thigh, and applying pressure on this point can help compress the artery against the underlying bone, reducing the blood flow and preventing further bleeding. This technique is commonly used in emergency situations to provide immediate first aid and buy time until professional medical help arrives.Rate this question:

Which of the following are signs and symptoms of a fracture?
- A.
Blisters, mottled skin, hoarseness.
- B.
Sweating, low blood pressure, pain.
- C.
Joint tenderness, loss of movement, crepitus.
- D.
Restlessness, thread-like pulse, shallow, rapid breathing.
Correct Answer
C. Joint tenderness, loss of movement, crepitus.Explanation
The signs and symptoms of a fracture include joint tenderness, loss of movement, and crepitus. Joint tenderness refers to pain or discomfort in the affected joint. Loss of movement refers to the inability to move the affected area or joint. Crepitus is a crackling or popping sound that may occur when the fractured bone moves or rubs against other bones. These signs and symptoms are commonly associated with a fracture and can help in diagnosing the condition.Rate this question:

A clean cut from a sharp edge is known as a/an __________.
- A.
Incision
- B.
Abrasion
- C.
Contusion
- D.
Laceration
Correct Answer
A. IncisionExplanation
An incision refers to a clean cut made by a sharp object or edge. It is a deliberate and controlled wound that is typically made during surgical procedures or medical interventions. Unlike abrasions, contusions, or lacerations, an incision is characterized by its precise and neat edges, indicating a deliberate and intentional cut rather than a result of scraping, bruising, or tearing.Rate this question:

Which of the following is not a sign or symptom of a fracture?
- A.
Swelling.
- B.
Deformity.
- C.
Breathlessness.
- D.
Loss of movement.
Correct Answer
C. Breathlessness.Explanation
Breathlessness is not a sign or symptom of a fracture because a fracture is a break or crack in a bone, which does not directly affect the respiratory system. Swelling, deformity, and loss of movement are commonly associated with fractures as the body's response to the injury. However, breathlessness may indicate other medical conditions such as respiratory problems or cardiovascular issues, but it is not directly related to fractures.Rate this question:

Which type of burns may induce cardiac arrest?
- A.
Thermal burns.
- B.
Electrical burns.
- C.
Chemical burns.
- D.
None of the above.
Correct Answer
B. Electrical burns.Explanation
Electrical burns can induce cardiac arrest because they can disrupt the normal electrical activity of the heart. When a person comes into contact with an electrical source, the electrical current can pass through the body and interfere with the heart's rhythm, potentially leading to cardiac arrest. Thermal burns, caused by heat or fire, and chemical burns do not directly affect the heart's electrical activity and are therefore less likely to induce cardiac arrest.Rate this question:

A torn or lacerated wound can be identified as __________ .
- A.
Bleeding under skin
- B.
A clean cut caused by sharp cutting instruments
- C.
Large in area and caused by sharp cutting instruments
- D.
Jagged edges caused by machinery, claws of animals, etc
Correct Answer
D. Jagged edges caused by machinery, claws of animals, etcExplanation
A torn or lacerated wound can be identified by jagged edges caused by machinery, claws of animals, etc. This type of wound is not a clean cut caused by sharp cutting instruments, but rather has irregular and rough edges. It is also different from a wound that is large in area and caused by sharp cutting instruments, as the size of the wound is not the defining characteristic of a torn or lacerated wound.Rate this question:

The blood vessels that carry blood back to the heart are called ____________ .
- A.
Veins
- B.
Valves
- C.
Arteries
- D.
Capillaries
Correct Answer
A. VeinsExplanation
Veins are the correct answer because they are the blood vessels that carry blood back to the heart. Arteries carry oxygenated blood away from the heart, capillaries are the smallest blood vessels that connect arteries and veins, and valves are structures within veins that prevent blood from flowing backward.Rate this question:

Which type of soft tissue injury has the upper most layer of skin scraped away?
- A.
Incision
- B.
Avulsion
- C.
Abrasion
- D.
Laceration
Correct Answer
C. AbrasionExplanation
An abrasion is a type of soft tissue injury where the uppermost layer of skin is scraped away. This can occur when the skin rubs against a rough surface, causing friction and damage to the skin. Unlike an incision, which is a clean cut made by a sharp object, an abrasion involves the removal of superficial layers of skin. Avulsion refers to the tearing away of skin or tissue, while a laceration is a deep cut or tear in the skin.Rate this question:

Applying pressure on the carotid pressure point prevents blood from flowing to the_____________.
- A.
Head
- B.
Lower limbs
- C.
Whole body
- D.
Upper and lower arms
Correct Answer
A. HeadExplanation
Applying pressure on the carotid pressure point can disrupt the blood flow to the head. The carotid arteries are major blood vessels that supply oxygenated blood to the brain. By applying pressure on these arteries, blood flow can be temporarily restricted, leading to a decrease in blood supply to the head. This can result in dizziness, loss of consciousness, and potentially prevent blood from reaching the brain, causing temporary impairment or even brain damage if sustained for a prolonged period of time.Rate this question:

Which type of burns destroy tissue through protein coagulation?
- A.
Thermal burns.
- B.
Electrical burns.
- C.
Chemical burns.
- D.
None of the above.
Correct Answer
C. Chemical burns.Explanation
Chemical burns destroy tissue through protein coagulation. When a chemical comes into contact with the skin, it can cause a chemical reaction that leads to the coagulation or denaturation of proteins in the affected area. This coagulation causes damage to the tissue and can result in severe burns. Thermal burns, on the other hand, are caused by heat sources such as fire or hot objects, while electrical burns are caused by electric current passing through the body. Therefore, the correct answer is chemical burns.Rate this question:

Which of the following is not an open wound?
- A.
Incision
- B.
Contusion
- C.
Amputation
- D.
Evisceration
Correct Answer
B. ContusionExplanation
A contusion is not an open wound because it is a closed injury where the skin is not broken. It occurs when the body experiences blunt force trauma, causing damage to the blood vessels and underlying tissues, resulting in bruising. Unlike an incision, amputation, or evisceration, which all involve the breaking or cutting of the skin, a contusion does not create an open wound.Rate this question:

What kind of wound occurs when a large amount of force impacts on arteries and veins close to skin?
- A.
Abrasion.
- B.
Contusion.
- C.
Laceration.
- D.
Haematoma.
Correct Answer
D. Haematoma.Explanation
A haematoma occurs when a large amount of force impacts on arteries and veins close to the skin, causing them to rupture and blood to pool in the surrounding tissue. This can result in a painful, swollen area that may appear bruised. An abrasion is a superficial wound caused by scraping or rubbing of the skin, a contusion is a bruise resulting from blunt force trauma, and a laceration is a deep cut or tear in the skin.Rate this question:

________ is the cracking sound made by the movement of broken bone ends.
- A.
Crepitus
- B.
Distension
- C.
Aggravation
- D.
Discolouration
Correct Answer
A. CrepitusExplanation
Crepitus is the correct answer because it refers to the cracking sound made by the movement of broken bone ends. It is a common symptom of bone fractures and can also occur in other conditions such as arthritis. Distension refers to the swelling or enlargement of a body part, aggravation refers to the worsening or increase in severity of a condition, and discoloration refers to a change in color, none of which specifically relate to the cracking sound made by broken bone ends.Rate this question:

Which of the following should you treat first?
- A.
Second degree burn.
- B.
Fracture on arm.
- C.
Arterial haemorrhage.
- D.
Venous haemorrhage.
Correct Answer
C. Arterial haemorrhage.Explanation
Arterial haemorrhage should be treated first because it involves bleeding from an artery, which carries oxygenated blood from the heart to the rest of the body. Arterial bleeding can be life-threatening and can lead to severe blood loss and shock if not addressed immediately. It requires immediate attention to control the bleeding and prevent further complications. Second degree burns, fractures, and venous haemorrhage are also important to treat, but they are not as immediately life-threatening as arterial haemorrhage.Rate this question:

“Characterized by red or mottled skin, often with blisters”. Which degree of burn does this description belong to?
- A.
First degree burn.
- B.
Second degree burn.
- C.
Third degree burn.
- D.
None of the above.
Correct Answer
B. Second degree burn.Explanation
The description of red or mottled skin, often with blisters, is indicative of a second-degree burn. A first-degree burn typically causes redness and mild pain, but does not result in blisters. A third-degree burn would cause severe damage to the skin, including charring and a white or black appearance, which is not mentioned in the description. Therefore, the correct answer is second-degree burn.Rate this question:

Which of the following is/are a type of haemorrhage?
- A.
Arterial haemorrhage.
- B.
Venous haemorrhage.
- C.
Capillary haemorrhage.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
All of the options listed - arterial haemorrhage, venous haemorrhage, and capillary haemorrhage - are types of haemorrhage. Haemorrhage refers to the escape of blood from blood vessels due to injury or rupture. Arterial haemorrhage occurs when there is bleeding from an artery, venous haemorrhage occurs when there is bleeding from a vein, and capillary haemorrhage occurs when there is bleeding from capillaries, which are the smallest blood vessels in the body. Therefore, all three options are correct as they represent different types of haemorrhage.Rate this question:

Which of the following is/are dangers of a haemorrhage?
- A.
Death.
- B.
Shock.
- C.
Blood loss.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
A haemorrhage refers to excessive bleeding, which can be life-threatening. Death can occur if the bleeding is not controlled or treated promptly. Shock is another danger of haemorrhage, as it can result from the loss of a significant amount of blood, leading to a decrease in blood pressure and inadequate oxygen supply to the body's organs. Additionally, haemorrhage causes blood loss, which can lead to complications such as organ damage, anemia, and further medical emergencies. Therefore, all of the listed options are dangers associated with a haemorrhage.Rate this question:
