Body Temperature

What is the normal range of human body temperature?

• 96.5°F to 99.5°F (36°C to 38°C)

• 97.5°F to 100.5°F (37°C to 39°C)

• 95.5°F to 97.5°F (35°C to 36°C)

• 96.5°F to 98.5°F (36°C to 37°C)

What is the average human oral temperature?

• 100.4°F (39°C)

• 96.5°F (36°C)

• 99.5°F (38°C)

• 98.6°F (37°C)

How much does the average human body temperature fluctuate within a 24-hour period?

• 1° to 2°

• 0.5° to 1°

• 2° to 3°

• 3° to 4°

When does the lowest body temperature typically occur?

• During exercise

• When exposed to cold temperatures

• During sleep

• After eating

Why do infants have difficulty regulating their body temperature?

• Their metabolic rate is slower.

• Their sweat glands are underdeveloped.

• Their circulatory system is inefficient.

• They have more surface area (skin) relative to volume and lose heat more rapidly.

Why do elderly individuals often have difficulty regulating their body temperature?

• They have more subcutaneous fat.

• Their temperature-regulating mechanisms function less efficiently.

• Their sweat glands are overactive.

• Their metabolic rate is higher.

What is insensible water loss?

• Water loss through urination

• Water loss through the respiratory tract

• Water loss through the skin's permeability and evaporation, unrelated to sweating

• Water loss through sweating

What can happen to elderly individuals during prolonged exposure to high environmental temperatures?

• They may experience increased energy and alertness.

• They may experience improved circulation and reduced joint pain.

• They may develop an increased tolerance to heat.

• It can be dangerous due to their decreased temperature regulation and inactive sweat glands.

Why are quadriplegics at greater risk for hypothermia?

• Their sweat glands are overactive, leading to excessive heat loss.

• They have a higher metabolic rate and generate too much heat.

• They have no sensation of cold in their body and may have lower heat production due to inactivity.

• Their blood vessels are constricted, reducing blood flow to the extremities.
