Exam 1 (Vital signs, physical assessment, Safety, medication administration, Pharmacology) 2023 latest 1. MAP=: SBP+2(DBP)/3 2. CO (cardiac output)=: SV(stroke volume) x HR(heart rate) 3. Physiological process involved in regulation of Temperature: Heat generated by..: Metabolism, hormones, movement and excercise 4. Metabolic influence on Temperature: increased metabolic rate = increased temp. 5. Age influences on metabolism (temp): Children & athletes have high metabolism. Older adults have lower metabolism. 6. Thyroid hormone influnence on Temp:: Hypo: decreased metabolism, Hyper: increased metabolism. 7. Estrogen and testosterone influence on temp:: Testosterone= faster metabolism. Estrogen= increased heat production 8. Heat loss: 1. controlled by of heat loss: 1. anterior hypothalamus 2. Evaporation, conduction, radiation, convection 9. Evaporation:: larger surface area=more evaporation 10. Excercise/movement effect on temp:: more excerise=better circulation=increased temp 11. Dilation: cold vs. heat: cold=vessels constrict heat=vessels dialate 12. Pulse: Controlled by:: Autonomic NS (involuntary) Parasympathetic NS (rest and digest), sympathetic NS (fight or flight) 13. Factors effecting body temp:: Circadian rhythm, Age, Gender, physical activity, health status, environmental temp. 14. Gender influnces on temp: Men warmer 15. Pyrogens: alter thermostat in hypothalamus, most extreme in young, think of febrile seziures in peds
