EMS Pre-Hospital Care & Treatment

Question 1

What is the first step in assessing an unresponsive patient in a pre-hospital setting?

Accepted Answer

Check for responsiveness

Answer

In a pre-hospital setting, the first step in assessing an unresponsive patient is to check for responsiveness. This involves gently tapping the patient and shouting to see if they react, which quickly determines their level of consciousness. Establishing responsiveness guides subsequent assessment steps, such as checking for breathing and pulse, and initiating appropriate interventions.

Question 2

Which technique is recommended for opening the airway of an unconscious patient without a suspected spinal injury?

Accepted Answer

Head-tilt, chin-lift

Answer

For an unconscious patient without a suspected spinal injury, the recommended technique for opening the airway is the head-tilt, chin-lift maneuver. This simple yet effective method moves the tongue away from the back of the throat, which is a common cause of airway obstruction in unconscious individuals. It ensures a patent airway for breathing or ventilation.

Question 3

Why is early defibrillation critical in cardiac arrest cases?

Accepted Answer

It increases survival chances by restoring normal rhythm

Answer

Early defibrillation is critical in cardiac arrest cases because it significantly increases survival chances by restoring a normal heart rhythm. Many cardiac arrests are caused by ventricular fibrillation, an erratic electrical activity in the heart. Defibrillation delivers an electrical shock that can reset the heart, allowing it to pump blood effectively again.

Question 4

Which vital sign is most indicative of shock in a trauma patient?

Accepted Answer

Decreasing blood pressure

Answer

In a trauma patient, decreasing blood pressure is often the most indicative vital sign of shock. Shock is a life-threatening condition where the body isn't getting enough blood flow, leading to inadequate oxygen delivery to tissues. While other signs like increased heart rate or respiratory rate may appear earlier, a drop in blood pressure signals a more advanced and critical stage of shock.

Question 5

How should a first responder treat a patient with severe external bleeding?

Accepted Answer

Apply direct pressure to the wound

Answer

For a patient with severe external bleeding, a first responder should immediately apply direct pressure to the wound. This is the most effective initial step to control blood loss by compressing the damaged blood vessels. Maintaining firm, continuous pressure helps to promote clotting and prevent further hemorrhage, which is crucial for patient survival.
