RNSG 1430 Thermoregulation || with Complete Solutions.

thermoregulation correct answers the process of maintaining core body temperature within an optimal physiological range. critical for optimal physiological function hypothalamus correct answers controls body temperature and signals for mechanisms to increase heat production or facilitate heat loss decreased temperature correct answers blood vessels constrict, sweat glands less active, skeletal muscles contract, causing shivering increased temperature correct answers blood vessels dilate, giving flushed appearance; sweat glands become more active normothermia correct answers 97.7 - 98.96 F 36.5 - 37.2 C will vary in range hypothermia correct answers below 98- 93.3 (no function-death) rectal temperature correct answers most accurate for core temperature basal metabolic rate correct answers the rate of energy utilization in the body required to maintain essential activities such as breathing Metabollic rate in elderly correct answers decreases shivering correct answers Which of the following is a physiologic response to hypothermia? Covering up with a blanket Drinking warm fluids Shivering Increasing physical activity Thyoxine (T4) correct answers main hormone produced by thyroid gland, controls body basal metabolic rate, deficiency lower metabolic rate D. Radiation correct answers When the ambient air temperature exceeds that of body temperature, which type of heat transfer ability is lost? A. Convection B. Conversion C. Evaporation D. Radiation chemical thermogenesis correct answers the stimulation of heat production in the body through increased cellular metabolism caused by increases in thyroxine output sympathetic stimulation correct answers Neurotransmitter hormones of epinephrine and norepinephrine increases metabolic rate "fight or flight" mechanism physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival
