NTN Emergency Medical Procedures 3

Question 1

A patient is found in cardiac arrest and an AED is available. After turning on the AED and attaching the pads, the device advises 'No shock advised.' What should the rescuer do next?

Accepted Answer

Immediately resume CPR for 2 minutes

Answer

When an AED advises no shock, the patient's rhythm is not shockable (asystole or PEA). The rescuer should immediately resume CPR for 2 minutes before the AED reanalyzes the rhythm.

Question 2

Which of the following signs would indicate tension pneumothorax in a trauma patient?

Accepted Answer

Tracheal deviation away from the affected side and distended neck veins

Answer

Tension pneumothorax presents with tracheal deviation toward the unaffected side (pushed away from the pressure), distended jugular veins (due to impaired venous return), absent breath sounds on the affected side, and hypotension.

Question 3

What is the recommended fluid for initial resuscitation of a burn patient in the prehospital setting?

Accepted Answer

Normal saline (0.9% NaCl) or lactated Ringer's

Answer

Normal saline or lactated Ringer's solution is the standard isotonic crystalloid used for initial fluid resuscitation in burn patients to replace fluid losses and maintain perfusion.

Question 4

A first responder is treating a patient who was exposed to an organophosphate chemical. Which medication is the primary antidote?

Accepted Answer

Atropine

Answer

Atropine is the primary antidote for organophosphate poisoning. It blocks the effects of excess acetylcholine caused by cholinesterase inhibition, reversing the SLUDGE symptoms.

Accepted Answer

One breath every 3-5 seconds (12-20 breaths per minute)
