Question 1: What part of the body regulates core body temperature?

Answer:

Hypothalmus (the body's thermostat)

Question 2: In what ways can the body lose heat?

Answer:

Radiation, conduction, convection, vasodilation, evaporation, reduced muscle activity, increased respirations Question 3: If someone has a fever/hyperthermia, it is okay to give cool sponge baths, cooling blankets, and ice packs? True or false?

Answer:

False, they can increase shivering which is counterproductive, and increase temperature

Question 4: What are clincal manifestations of hyperthermia?

Answer:

Flushed skin, warm/hot to touch, diaphoretic, dry skin mucosa, seizures, confusion, coma

Question 5: In what person is basal metabolic rate (BMR) higher in?

Answer:

Higher in the younger, lower in the older

Question 6: What are clinical manifestations of hypothermia?

Answer:

Cool pale skin, cyanosis, slow cap refill, rigid muscles, dysrhythmias, confusion, coma

Question 7: Which core temperature site is preferred, rectal or tympanic?

Answer:

Tympanic because it is less invasive

Question 8: How do you treat someone with hypothermia?

Answer:

Warm head coverings, warm blankets, warm IV fluids, if patient is conscious have them drink warm soup or beverage

Question 9: What is therapeutic hypothermia used for?

Answer:

Often performed during procedures such as surgery/emergencies to reduce oxygen demand and reduce body's metabolic demand

Question 10: Are mild to moderate fevers beneficial to patients?

Answer:

Yes, it is part of the inflammatory response, and means our immune system is working properly

Question 11: How does increased respiratory contribute to heat loss?

Answer:

Cool air is inhaled, and is exchanged for warm air which is exhaled

Question 12: What is considered a hyperthermic temperature?

Answer:

>37.2C >99.7F

Question 13: Are axillary temps accurate in adults? True or False?

Answer:

False

Question 14: How do we lose heat through vasodilation?

Answer:

Causes larger amount of blood to come up to surfaces of tissue

Question 15: Is a tympanic temperature a core temperature (ear)? True or false?

Answer:

True

Question 16: How is evaporation involved in heat loss?

Answer:

Converting water to gas (example: we perspire moisture is lose in the air)

Question 17: What is the definition for febrile?

Answer:

Describes a person with a fever

Question 18: What is thermoregulation?

Answer:

Factors that regulate body temperature. The process of maintaining the core body temperature at nearly a constant value

Question 19: How does convection contribute to heat loss?

Answer:

Process of losing heat through water or air (example: using fan to cool off skin or wearing wet clothes=accelerates heat loss)

Question 20: How does conduction contribute to heat loss?

Answer:

Direct contact of 1 surface to another. Warmer surfaces lose heat to colder surfaces. (Example: heat loss through sleeping on cold ground)

Question 21: What is the definition of heat stroke?

Answer:

When prolonged exposure to high environmental temps overwhelms the body's heat loss mechanisms

Question 22: How does radiation contribute to heat loss?

Answer:

It is heat lost through infrared rays from one object to another without physical contact (Examples: sun heating earth)

Question 23: What is the temperature range for hyperpyrexia?

Answer:

Above a 41.5C or 106.7 F

Question 24: Are axillary temperatures accurate in infants? True of false?

Answer:

True

Question 25: How does reduced muscle activity contribute to heat loss?

Answer:

Lack on muscle contraction= less heat production

Question 26: What medications can be administered for fever reduction?

Answer:

Ibuprofen or acetaminophen

Question 27: What is considered a hypothermic temperature?

Answer:

30C-34C

Below 97.2F

Question 28: What are factors that impact thermoregulation?

Answer:

Age, diurnal variations (time of day), exercise, hormones, stress, environment
