1. A young male was struck in the forearm with a baseball and complains of pain to the area. Slight swelling and ecchymosis are present, but no external bleeding. What type of injury does this describe?

A. AbrasionB. ContusionC. HematomaD. Avulsion

Page 37: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: B

Rationale: A contusion (bruise) is caused by direct blunt force trauma. The epidermis remains intact, but small blood vessels in the dermis are injured. The depth of the injury varies, depending on the amount of energy absorbed. Pain and swelling occur as fluid and blood leak into the damaged area. The buildup of blood produces a characteristic blue and black discoloration called ecchymosis.

A. AbrasionRationale: An abrasion is a wound of the superficial layer of skin, caused by

friction.B. ContusionRationale: Correct answerC. HematomaRationale: Hematoma is blood that has collected within damaged tissue or in

a body cavity, associated with large blood vessel damage.D. AvulsionRationale: An avulsion is an injury that separates various layers of tissue.

2. The primary reason for applying a sterile dressing to an open injury is to:

A. prevent contamination.B. control external bleeding.C. reduce the risk of infection.D. minimize any internal bleeding.

Page 40: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

3. Which of the following is considered a critical burn?

A. Any full-thickness burnB. 20% partial-thickness burnC. 10% full-thickness burn with abrasionsD. 5% full-thickness burn with a fracture

Page 43: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: D

Rationale: Critical burns include the following: partial- and full-thickness burns involving the hands, feet, face, airway, or genitalia; full-thickness burns covering more than 10% of the body surface area; burns involving the respiratory tract (ie, smoke inhalation); burns complicated by fractures; and burns on patients younger than 5 years or older than 55 years that would otherwise be classified as “moderate” burns on younger adults.

4. A 22-year-old male was attacked by a rival gang and has a large knife impaled in the center of his chest. Your assessment reveals that he is apneic and pulseless. You should:

A. carefully remove the knife, control any bleeding, begin CPR, and transport.

B. stabilize the knife in place, provide rescue breathing, and transport at once.

C. remove the knife and control any bleeding, apply the AED, and analyze his rhythm.

D. begin CPR, control any external bleeding, and transport rapidly to a trauma center.

Page 46: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: A

Rationale: As a rule, impaled objects should be stabilized in place. However, if they interfere with the patient’s breathing or your ability to perform CPR, they should be removed. You cannot perform CPR on a patient if a knife is impaled in the center of the chest. Carefully remove the knife, control any bleeding, begin CPR, and transport at once. The AED is not indicated for patients with traumatic cardiac arrest; their arrest is usually caused by massive blood loss, not a primary cardiac dysrhythmia.

5. The MOST appropriate way to dress and bandage an open abdominal wound with a loop of bowel protruding from it is to:

A. cover the wound with a dry, sterile dressing and apply firm pressure.

B. apply a moist, sterile dressing to the wound and apply firm pressure.

C. apply a moist, sterile dressing to the wound followed by a dry, sterile dressing.

D. carefully replace the protruding bowel into the abdomen and cover the wound.

Review

Answer: C

Rationale: Treatment for an abdominal evisceration includes applying a moist, sterile dressing to the wound and covering the moist dressing with a dry one. Do not replace a protruding bowel back into the wound or apply firm pressure, which may force the bowel back into the wound; these actions increase the risk of infection.

6. A 5-year-old boy was burned when he pulled a barbecue pit over on himself. He has partial and full-thickness burns to his anterior chest and circumferentially on both arms. What percentage of his body surface area has been burned?

A. 18%B. 27%C. 36%D. 45%

Page 53: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: B

Rationale: Using the pediatric rules of nines, the anterior chest accounts for 9% of the body surface area (the entire anterior trunk, which includes the chest and abdomen, account for 18% of the body surface area [BSA]), and each arm accounts for 9% of the BSA. Therefore, this child has experienced 27% BSA burns.

8. A 45-year-old convenience store clerk was shot in the right anterior chest during a robbery. Your assessment reveals that the wound has blood bubbling from it every time the patient breathes. Your MOST immediate action should be to:

A. prevent air from entering the wound. B. cover the wound with a bulky dressing. C. assess the patient’s back for an exit wound. D. transport promptly to the closest trauma center.

Page 59: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: A

Rationale: Immediate treatment for a sucking chest wound (open pneumothorax) involves covering the wound with an occlusive (non-porous) dressing. This will prevent air from being drawn into the chest cavity. After covering the wound, assess for an exit wound, apply high-flow oxygen (if not already done), and transport promptly.

10. A compression injury that is severe enough to cut off blood flow below the injury is called:

A. a contusion.B. a hematoma.C. a local thrombus.D. compartment syndrome.

Page 65: You are the provider continued (2 of 3) You and your partner opt to perform a rapid physical exam. Partner maintains c-spine precautions. You determine

Review

Answer: D

Rationale: Compartment syndrome can occur when a part of the body has been compressed for a prolonged period of time—usually greater than 4 hours. The injured tissue begins to swell, which can impede arterial blood flow and venous return. As a result, the part of the body distal to the compression site becomes hypoxic and metabolic waste products (ie, lactic acid) begin to accumulate.
