Basic EMT Environmental Emergencies Exam

Which of the following is one of the four factors that affect how a person deals with exposure to a cold or hot environment?

• Blood type

• Age

• Primary language

• Occupation

A person who is poorly nourished and dehydrated is at a higher risk for environmental emergencies because:

• They sweat more profusely, leading to rapid cooling.

• Their basal metabolic rate increases rapidly in response to temperature changes.

• They lack the energy reserves and fluid volume needed to regulate body temperature effectively.

• Their skin becomes thicker, reducing sensory input.

The primary method of heat loss that occurs when a patient sweats or exhales moist air is:

• Conduction

• Convection

• Radiation

• Evaporation

Tags

NGSS.MS-PS1-4

Heat loss that occurs when heat is transferred from the body to an object (like a cold metal chair) through direct contact is called:

• Conduction

• Convection

• Radiation

• Evaporation

Heat loss that occurs when air or water molecules move across the skin is known as:

• Conduction

• Convection

• Radiation

• Respiration

In a warm environment, the body loses the greatest amount of heat through which mechanism?

• Conduction

• Evaporation

• Radiation

• Respiration

Tags

NGSS.HS-LS1-3

Heat loss through respiration is most significant in which type of environment?

• Warm and humid

• Cold and dry

• Warm and wet

• Moderate and dry

To modify heat loss via convection in an emergency, the EMT should:

• Place a cold pack on the patient's neck.

• Shield the patient from wind or moving air.

• Immediately remove all wet clothing.

• Encourage the patient to shiver.

Why are infants particularly susceptible to hypothermia?

• They have an underdeveloped sweating mechanism.

• They have a lower heart rate than adults.

• They have a large surface area-to-mass ratio.

• They are unable to move to generate heat.

Which action best modifies heat loss via conduction for a hypothermic patient on a cold concrete floor?

• Covering the patient's head with a dry towel.

• Placing a blanket or insulating pad beneath the patient.

• Turning on the heat in the ambulance.

• Removing the patient's wet socks.
