Medical Technicians EMT Exam Questions and Answers PDF

An externally rotated, shortened leg is a classic sign of a proximal femur fracture, specifically a femoral neck or intertrochanteric fracture, commonly seen in elderly fall patients. This presentation reflects muscle pull and fracture displacement.

Posterior hip dislocations cause internal rotation.

Pelvic fractures may cause instability but not specific leg rotation/shortening.

Colles ' fracture is a distal radius (wrist) injury, unrelated to leg trauma.

The symptoms and vital signs (wheezing, hypotension, high pulse rate, respiratory distress) are strongly indicative of anaphylaxis, which is a life-threatening allergic reaction. Bilateral wheezing and hypotension further confirm systemic involvement. The first-line treatment is intramuscular epinephrine, which:

Reverses bronchospasm (via beta-2 adrenergic effects)

Raises blood pressure (via alpha-1 vasoconstriction)

Improves airway tone and reduces mucosal edema

A metered-dose inhaler may help in mild bronchospasm but is insufficient during anaphylactic shock. Positive pressure ventilations are a secondary measure if respiratory failure occurs. Nitroglycerin is contraindicated due to low BP.

After ROSC in an unresponsive patient, the left lateral recumbent position (also called the recovery position) is preferred to:

Maintain an open airway

Prevent aspiration if vomiting occurs

Promote drainage of secretions

Supine or Trendelenburg positions increase the risk of aspiration. Elevating the head to 45° may reduce intracranial pressure, but it’s not standard post-ROSC care in an unresponsive patient unless airway protection is ensured.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Upon arrival, EMTs must immediately perform a scene size-up, which focuses on safety and incident management rather than patient treatment.

Option A (Identifying hazards) is correct because recognizing dangers such as traffic, fire, violence, or hazardous materials is essential to prevent responder injury.

Option E (Requesting additional resources) is correct because early recognition of the need for more personnel, ALS support, fire services, or law enforcement improves patient outcomes and scene control.

Option B is incorrect because ruling out life threats occurs during the primary assessment, not immediately upon arrival.

Option C is incorrect because patient treatment must wait until scene safety is confirmed.

Option D is incorrect because PPE use is a personal responsibility, not a primary scene-arrival task.

NREMT stresses that effective EMS operations begin with safety, situational awareness, and resource management.
