1. Which of the following is NOT a mechanism of heat loss?
*
a. radiation
b. transduction
c. convection
d. evaporation
2. Which fibres are responsible for the detection of decreases in body temperature?
*
a. C fibres
b. A-δ fibres
c. A-β fibres
3. Which part of the brain is responsible for initiating a response to changes in body temperature?
*
a. temporal lobe
b. cerebellum
c. hypothalamus
d. pituitary gland
4. During which phase of heat loss is the greatest loss expected to occur?
*
a. Phase I
b. Phase II
c. Phase III
5. Which of the following is a direct result of hypothermia?
*
a. hypertension
b. hypercapnia
c. hyperoxemia
d. cardiac arrhythmias
6) The use of electric heating pads is appropriate for warming an anesthetized patient.
*
a. true
b. false
7. What causes malignant hyperthermia?
*
a. genetic mutation activated by anesthetic agents
b. large, heavy coated canine breeds
c. patients with too much heat support
d. use of succinylcholine
8. What is the goal of pre-warming both the patient and the induction area?
*
a. to increase the patient’s peripheral body temperature prior to induction of anesthesia
b. to decrease the patient’s peripheral body temperature prior to induction of anesthesia
c. to decrease the amount of blood flow redistribution to the periphery, resulting in a decrease in radiation heat loss
d. a&c
9. If the RVT monitoring a patient notes mild iatrogenic hyperthermia, which measures should they take?
*
a. all heating sources must be turned off and removed from contact with the patient
b. any material wrapped around the extremities must be removed
c. intravenous fluid therapy can be administered; the warm fluids can help decrease the patient’s core body temperature
d. a&b
