Medical Tests NREMT Online Questions & Answers

• Question 1:

  You are treating a 24-year-old female with a gunshot wound to the right side of the back. No exit wound is visible. She is awake but confused. Her skin is pale and diaphoretic with cyanosis noted to the oral mucosa. Breath sounds are clear

  and equal bilaterally. Jugular vein distention is present. Blood pressure is 90/78 mmHg, heart rate is 124 beats per minute, and respiratory rate is 28 per minute and labored. Sinus tachycardia is seen on the cardiac monitor.

  What condition do you think is most likely present with this patient?

  A. Hemothorax
  B. Tension pneumothorax
  C. Pericardial tamponade
  D. Lacerated aorta
  C. Pericardial tamponade

  ---

  explanation:

  Explanation/Reference:

  Pericardial tamponade causes decreased cardiac output as seen by pale skin and hypotension. In addition, jugular vein distention may seen along with a narrowed pulse pressure. Other signs and symptoms include tachycardia, respiratory difficulties, and cyanosis of the face, neck, and arms. With tension pneumothorax or a significant hemothorax, decreased or absent breath sounds will be present.

• Question 2:

  A large collection of blood under the skin is known as?

  A. Contusion
  B. Abrasion
  C. Hematoma
  D. Bruise
  C. Hematoma

  ---

  explanation:

  Explanation/Reference:

  A hematoma is a large collection of blood, caused by larger blood vessels being damaged. A hematoma often is located between layers of tissues. A contusion is generally a smaller collection of blood within tissue such as the dermis. A bruise is a generic term which is often used interchangeably between a contusion and a larger hematoma.

• Question 3:

  When approaching a scene of trauma incident your first order of business?

  A. Airway
  B. C-Spine control
  C. Body substance Isolation
  D. Scene safety
  D. Scene safety

  ---

  explanation:

  Explanation/Reference:

  Scene safety must be the first order of business upon approaching the scene, if you are injured then you can not help those you were called to help, plus you will now compound the incident since you are now a victim. Body substance isolation is important after you arrive the scene and approach the patient (s). Once you find the patient then Airway/C-spine control are the next steps.

• Question 4:

  The way a patient is injured is often referred to as the _______________?

  A. Mechanism of injury
  B. Mechanics of injury
  C. Injury pattern
  D. Energy transfer
  A. Mechanism of injury

  ---

  explanation:

  Explanation/Reference:

  The mechanism of injury transfers energy to the patient causing a pattern of injury which is predictable. The way a patient is injured is referred to as the Mechanism of injury a frontal impact auto accident is the mechanism of injury. This allows the clinician to predict the type of injuries the patient may have and predict their response to treatment. Injury pattern can be predicted by looking a the mechanism of injury.

• Question 5:

  When there is penetrating trauma there is a permanant cavity which is formed by the projectile contacting the tissues, how is a tempoary cavity formed?

  A. By the twisting of the projectile
  B. By energy scrubbing off of the projectile
  C. The wadding entering the body
  D. Unspent gun powder
  B. By energy scrubbing off of the projectile

  ---

  explanation:

  Explanation/Reference:

  When a projectile is traveling through space it is giving off energy as it pushes away the air molecules. When it impacts with human tissue kinetic energy is taken away from the projectile to the tissues. When this projectile is a high velocity missile the tissues which absorb this energy transfer is often damaged but not disrupted enough to be permanently damaged.

• Question 6:

  Any penetrating missile traveling over 2,000ft/sec would be classified as?

  A. Low velocity
  B. Medium velocity
  C. High velocity
  D. Decelerating
  C. High velocity

  ---

  explanation:

  Explanation/Reference:

  Any projectile which Is traveling greater than 2,000ft/sec in indeed high velocity and carry with it high potential for kinetic energy transfer. These would be a rifle rounds which can deliver a large projectile over long distances with devastating consequences.

• Question 7:

  Of the two types of energy transfer, which type would a Motor Vehicle crash (MVC) with frontal impact, non-restrained driver with bent steering wheel and spidered windshield?

  A. High velocity penetrating
  B. Decelerating
  C. Low velocity penetrating
  D. Blunt
  D. Blunt

  ---

  explanation:

  Explanation/Reference:

  Blunt trauma is just not getting stabbed or shot. Blunt trauma is any injury which is caused by something sticking the human body and having energy transferred to the human body. Blunt trauma can be caused by decelerating injury like a front end impact of a car against a tree.

• Question 8:

  Your patient has a laceration to the right leg which has intersected the femoral artery.

  You have applied direct pressure to the wound, but it continues to soak through the bandages.

  What should you do next?

  A. Apply a tourniquet
  B. Elevate the Leg
  C. Remove the old bandage and apply new ones
  D. Apply pressure to the pressure point just above the injury
  B. Elevate the Leg

  ---

  explanation:

  Explanation/Reference:

  Elevating the leg above the heart can help control bleeding. IF that fails the next step would be to use a pressure point. When applying bandages you should not remove the old ones, just apply the new ones over the old ones.

• Question 9:

  A laceration, spurting bright red blood most likely means what type of injury.

  A. Venous
  B. Arterial
  C. Capillary
  D. Amputation
  B. Arterial

  ---

  explanation:

  Explanation/Reference:

  The brighter the blood the more oxygen it holds, Because arterial blood comes from the heart it is rich in oxygen.

• Question 10:

  You patient is a 17 year old male found face down in a swimming pool. He is currently being help face up at the surface of the water, he is unconscious but breathing and has a pulse. What is the best course of action for this patient?

  A. Jump into the pool and begin CPR
  B. Remove the patient from the pool, immobilize, and transport.
  C. Apply cervical and spinal immobilization while the patient is still in the pool
  D. Wait for a trained water rescue team
  C. Apply cervical and spinal immobilization while the patient is still in the pool

  ---

  explanation:

  Explanation/Reference:

  Because you do not know what caused the patient to became unconscious spinal precautions need to be taken.
