NREMT Environmental Emergencies

Question 1

A patient is found in a hot environment with altered mental status, hot dry skin, and a core temperature of 104°F (40°C). Which condition does this presentation most likely indicate?

Accepted Answer

Heat stroke

Answer

Heat stroke is characterized by altered mental status, hot skin, and a core temperature exceeding 104°F (40°C), making it a life-threatening emergency requiring immediate cooling.

Question 2

A hypothermic patient who was previously shivering has now stopped shivering. What does this indicate?

Accepted Answer

The body can no longer generate compensatory heat, indicating worsening hypothermia

Answer

Cessation of shivering in a hypothermic patient indicates the body's thermogenic mechanisms have been overwhelmed, signaling progression to severe hypothermia.

Question 3

You arrive to find a drowning victim who has been removed from the water. The patient is unresponsive and pulseless. What is your immediate priority?

Accepted Answer

Begin CPR immediately

Answer

For a pulseless drowning victim, beginning CPR immediately is the highest priority, as prompt chest compressions and ventilations offer the best chance of survival.

Question 4

At a lightning strike mass casualty incident, which victim should receive priority care?

Accepted Answer

An unconscious patient with no detectable breathing

Answer

Lightning strike incidents use reverse triage: pulseless and apneic victims are prioritized because they have the greatest chance of survival with immediate CPR, unlike other MCI scenarios.

Question 5

A patient presents with heavy sweating, pale moist skin, weakness, nausea, and a core temperature of 101°F (38.3°C) after working in the heat. Which condition does this most likely represent?

Accepted Answer

Heat exhaustion

Answer

Heat exhaustion presents with heavy sweating, pale moist skin, weakness, and nausea with a mildly elevated temperature, distinguishing it from heat stroke which features altered mental status and higher core temperatures.
