NR601 Midterm (NR601)

Review Kennedy and Dunphy readings for age related changes KENNEDY:  Reduced physiological reserve of most body systems o Heart, Resp, Renal  Reduced homeostatic mechanisms (fail to adjust regulatory systems) o Temp, fluid and electrolytes  Changes in the sympathetic response o Orthostasis and falls, lack of hypoglycemic response  Impaired immunological function o Increase infections and autoimmune disease

NR601 Midterm Solution Guide What are the 3 primary physiological changes of aging? (ANS)- 1. Reduced physiological reserve of most body systems, esp. cardiac, resp, renal. 2. Reduced homeostatic mechanisms that fail to adjust regulatory systems (i.e. temp control, fluid/lyte balance, etc.). 3. Impaired immunological function (infection risk is greater, autoimmune dz's more prevalent) What is the preferred amount of exercise for elderly? (ANS)- 30min/day 5 days/wk of moderate exercise. ...
