Brain stem.

Injury to the head and neck may indicate injury to the:

Cervical spine.

The ideal procedure for moving an injured patient from the ground to a backboard is:

The four-person log roll.

You respond to a 38-year-old man who fell while rock climbing. He is unconscious with an open airway. The respiration and pulse rates are within normal limits. His distal pulses are intact. You check his pupils and find that they are unequal. You know this could be a sign of:

Increased intracranial pressure.

Once a cervical collar has been applied to a patient with a possible spinal injury, it should not be removed unless:

It causes a problem managing the airway.

A 45-year-old male was working on his roof when he fell approximately 12 feet, landing on his feet. He is conscious and alert and complains of an ache in his lower back. He is breathing adequately and has stable vital signs. You should:

Immobilize his spine and perform a focused secondary exam.

Which of the following statements regarding motor nerves is correct?

They carry information from the CNS to the muscles.

The hormone responsible for the actions of the sympathetic nervous system is:

Epinephrine.

Which of the following nerves allow sensory and motor impulses to be sent from one nerve directly to another?

Connecting.

In which of the following situations would the EMT be the LEAST likely to immobilize a patient's spine?

No distracting injuries or evidence of intoxication.

Neck rigidity, bloody cerebrospinal fluid, and headache are associated with what kind of bleeding in the brain?

Subarachnoid hemorrhage.

Rapid deceleration of the head, such as when it impacts the windshield, causes:

Compression injuries or bruising to the anterior portion of the brain and stretching or tearing to the posterior portion of the brain.

When immobilizing a trauma patient's spine, the EMT manually stabilizing the head should not let go until:

The patient has been completely secured to the backboard.

During your primary assessment of a 19-year-old unconscious male who experienced severe head trauma, you note that his respirations are rapid, irregular, and shallow. He has bloody secretions draining from his mouth and nose. You should:

Suction his oropharynx for up to 15 seconds.
