14 Questions
What is the acceptable range for average oral temperature in adults?
37°C (98.6°F)
What is the normal range for pulse in adults?
60 to 100 beats/min, strong and regular
What is the acceptable range for blood oxygen saturation (SpO2) in adults?
=95%
What is the acceptable range for respirations in adults?
12 to 20 breaths/min, deep and regular
What controls heat production in the body?
The posterior hypothalamus
What mechanisms does the body use to promote heat loss?
Sweating and vasodilation of blood vessels
What is the role of the hypothalamus in temperature regulation?
It senses minor changes in body temperature
What happens when nerve cells in the anterior hypothalamus detect elevated body temperature?
They send impulses to reduce body temperature
How does the body conserve heat when the posterior hypothalamus senses lower than normal body temperature?
By redistributing blood to surface vessels
What is the primary purpose of vasoconstriction in temperature regulation?
To reduce blood flow to the skin and extremities to prevent heat loss
What occurs when vasoconstriction is ineffective in preventing additional heat loss?
Muscle shivering begins
How do thyroid hormones affect the basal metabolic rate (BMR)?
They increase the BMR by promoting breakdown of body glucose and fat
What is the primary purpose of voluntary movements such as muscular activity during exercise?
To produce additional heat by increasing metabolic rate
What is the primary purpose of shivering in temperature regulation?
To equalize body temperature by producing additional heat
