| Description: - Significant differences exist between adults and infants in respect to fluid distribution, regulation of fluid and electrolyte balance and acid-base homeostasis. Differences exist due to: proportion and distribution of water Metabolic rate - Functional development of the kidneys - Body surface area - Breathing rate - Ion concentrations - Older adults often have impaired ability to maintain fluid, electrolyte and acid-base balance. Basically, all systems slow down and function less efficiently. - Older adults often suffer with: dehydration and hypernatremia – inadequate fluid intake, loss of more water than Na+ - Hypokalemia – chronic use of laxatives, drugs that cause K+ loss - Acidosis – impaired ability of lungs and kidneys to compensate for acid-base imbalances.
