Question

1. heat loss involving the transfer of heat to an object without physical contact is known as:

a. convection.
b. conduction.
c. radiation.
d. evaporation.

1. most body heat is lost through which part of the body?

a. the chest and back
b. the arms and legs
c. the head and neck
d. the abdomen and pelvis

1. which of the following is not a risk factor for a patients response to cold?

a. underlying medical condition
b. use of alcohol or drugs
c. age
d. altitude

1. a sign of mild hypothermia is:

a. increased blood pressure.
b. decreased breathing rate.
c. decreased pulse rate.
d. absence of shivering.

1. with severe hypothermic patients, it is recommended that a pulse check be done for __________ before a decision to start cpr.

a. 1 minute
b. 2 minutes
c. 30 seconds
d. 10 seconds

Explanation:

• Question 6: Radiation is heat transfer without physical contact. Convection involves fluid movement, conduction requires contact, and evaporation is a phase - change cooling.
• Question 7: The head and neck have a large surface area and blood flow, so most body heat is lost through them.
• Question 8: Altitude is not a direct risk factor for a patient's response to cold. Underlying medical conditions, alcohol/drug use, and age can affect thermoregulation.
• Question 9: In mild hypothermia, there is an increased blood pressure as the body tries to maintain core temperature. Decreased breathing and pulse rates and absence of shivering are more associated with severe hypothermia.
• Question 10: For severe hypothermic patients, a 1 - minute pulse check is recommended before starting CPR as hypothermia can slow physiological processes.

Answer:

1. C. radiation
2. C. The head and neck
3. D. Altitude
4. A. increased blood pressure
5. A. 1 minute
