NR 601 Midterm Exam review November 2020 Week 1 Developmental changes o Review Kennedy readings for age related changes Physiological Age related Change Functional Change Implications Integument... ary System Loss of dermal and epidermal thickness Loss of subcutaneous tissue and thin epidermis. Prone to skin breakdown and injury Decreased vascularity see • Atrophy of sweat glands resulting in decreased sweat production • Alteration in thermoregulatory response • Decreased body odor • Fluid requirements may change seasonally • Decreased heat loss • Loss of skin water • Dryness • Increased risk of heat stroke Respiratory System Decreased lung tissue elasticity Decreased vital capacity Reduced overall efficiency of ventilatory exchange Cilia atrophy Change in mucociliary transport Increased susceptibility to infection Decreased respiratory muscle strength • Reduced ability to handle secretions and reduced effectiveness against noxious foreign particles Increased risk of atelectasis • Partial inflation of lungs at restCardiovascular System Heart valves thicken and become fibrotic Reduced stroke volume, cardiac output; may be altered Decreased responsiveness to stress Fibroelastic thickening of the sinoatrial node; decreased number of pacemaker cells Slower heart rate Increased prevalence of arrhythmias Decreased baroreceptor sensitivity (stretch receptors) Decreased sensitivity to changes in blood pressure Prone to loss of balance, which increases the risk for falls GI Liver becomes smaller Decreased storage capacity Decreased muscle tone Altered motility Increases risk of constipation, functional bowel syndrome, esophageal spasm, diverticular disease Decreased basal metabolic rate (rate at which fuel is converted into energy) May need fewer calories NE CONDE) Lab results [Show More]
