9.

Which of the following statements regarding the clotting of blood is correct?

A person taking blood thinners will experience slower blood clotting.

By what mechanism is a person injured when he or she falls from a significant height?

Potential energy is converted to kinetic energy; the kinetic energy is then converted into the work of bringing the body to a stop.

Which of the following interventions is the MOST critical to the outcome of a patient with multisystem trauma?

Rapid transport to a trauma center

Which of the following body systems or components is the least critical for supplying and maintaining adequate blood flow to the body?

The filtering of blood cells in the spleen

Which of the following findings would be the most significant when assessing a patient with possible internal bleeding?

The patient takes rivaroxaban (Xarelto).

If direct pressure fails to immediately stop severe bleeding from an extremity, you should apply:

a tourniquet proximal to the injury.

A 48-year-old male has a suspected open-book pelvic fracture. He is conscious but restless, and his skin is pale and diaphoretic. His respirations are 22 breaths/min and his pulse rate is 120 beats/min. There is no external bleeding noted. The EMT should:

apply a compression device around his pelvis.

A 39-year-old male sustained a large laceration to his leg during an accident with a chainsaw and is experiencing signs and symptoms of shock. You should first:

apply direct pressure to the wound.

While assessing a young male who was struck in the chest with a steel pipe, you note that his pulse is rapid and irregular. You should be MOST suspicious for:

bruising of the heart muscle.

Perfusion is most accurately defined as the:

circulation of blood within an organ in adequate amounts to meet the body's metabolic needs.

Signs of a pulmonary blast injury include:

coughing up blood.

Two of the MOST common mechanisms of injury for blunt trauma are:

falls and motor vehicle collisions.

Evaluation of the interior of a crashed motor vehicle during extrication will allow the EMT to:

identify contact points and predict potential injuries.

Bleeding from the nose following head trauma:

is a sign of a skull fracture and should not be stopped.

Approximately 25% of severe injuries to the aorta occur during:

lateral collisions.

Early signs and symptoms of intra-abdominal bleeding include:

pain and distention.

A 43-year-old man is experiencing a severe nosebleed. His blood pressure is 190/110 mm Hg and his heart rate is 90 beats/min and bounding. Preferred treatment for this patient includes:

pinching the patient's nostrils and having him lean forward.

When caring for an occupant inside a motor vehicle equipped with an airbag that did not deploy upon impact, you should:

remember that it could still deploy and seriously injure you.

Internal bleeding into a fractured extremity is most often controlled by:

splinting the extremity.

A 15-year-old female was struck by a small car while riding her bicycle. She was wearing a helmet and was thrown to the ground, striking her head. In addition to managing problems associated with airway, breathing, and circulation, it is MOST important for you to:

stabilize her entire spine.

If one or more occupants in the same vehicle are killed in a crash, the EMT should:

suspect that all living occupants experienced the same serious trauma.

Regardless of the type of tourniquet used, it is important to remember that:

the tourniquet should only be removed at the hospital because bleeding might return if the tourniquet is released.

You should consider air medical transport of a trauma patient if:

traffic conditions hamper the ability to get the patient to a trauma center by ground within the ideal time frame for the best clinical outcome.

Capillaries link the arterioles and the:

venules.
