RNSG 1430 Thermoregulation Exam Questions with Correct Answers

RNSG 1430 Thermoregulation Exam Questions with Correct Answers thermoregulation - Answer-the process of maintaining core body temperature within an optimal physiological range. critical for optimal physiological function hypothalamus - Answer-controls body temperature and signals for mechanisms to increase heat production or facilitate heat loss decreased temperature - Answer-blood vessels constrict, sweat glands less active, skeletal muscles contract, causing shivering increased temperature - Answer-blood vessels dilate, giving flushed appearance; sweat glands become more active normothermia - Answer-97.7 - 98.96 F 36.5 - 37.2 C will vary in range hypothermia - Answer-below 98- 93.3 (no function-death) rectal temperature - Answer-most accurate for core temperature basal metabolic rate - Answer-the rate of energy utilization in the body required to maintain essential activities such as breathing Metabollic rate in elderly - Answer-decreases shivering - Answer-Which of the following is a physiologic response to hypothermia? Covering up with a blanket Drinking warm fluids Shivering Increasing physical activity Thyoxine (T4) - Answer-main hormone produced by thyroid gland, controls body basal metabolic rate, deficiency lower metabolic rate D. Radiation - Answer-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 - Answer-the stimulation of heat production in the body through increased cellular metabolism caused by increases in thyroxine output sympathetic stimulation - Answer-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 fever - Answer-protective immune response to foreign antigens in body diagnostic labs for fever - Answer-CBC Chest X-ray Urinalysis Conduction - Answer-The direct transfer of heat from one substance to another substance that it is touching. Convection - Answer-the transfer of heat by the movement of air or liquid moving past the body Evaporation - Answer-process of losing heat through the conversion of water to gas Radiation - Answer-transfer of heat from the surface of one object to the surface of another with no physical contact involved People at risk for risk factors affecting body temperature - Answer-infants/ young children, elderly, and people living in very cold or hot environments, low socioeconomic status Individuals at risk for risk factors affecting body temperature - Answer-cognitive impaired, underlying disease, genetics, athletes, construction workers celsius and fahrenheit - Answer-body temperature measured in degrees on two scales oral, rectal, axillary, tympanic membrane, and temporal scanner - Answer-sites for temperature measurement
