Notebook-Gould's Pathophysiology for the Health Professions

1. Notebook-Gould's Pathophysiology for the Health ProfessionsAtrophyHypertrophyHyperplasiaMetaplasiaDysplasiaAnaplasiaNeoplasiaEdema is usually more severe in dependent areas of the body, where the force of gravity is greatest, such as the buttocks, ankles, or feet of a person in a wheelchair. Prolonged edema interferes with venous return, arterial circulation, and cell function in the affected area.TABLE 2-3 Comparison of Signs and Symptoms of Fluid Excess (Edema) and Fluid Deficit (Dehydration)Fluid Excess (Edema)Fluid Deficit (Dehydration)Localized swelling (feet, hands, periorbital area, ascites)Sunken, soft eyesPale, gray, or red skin colorDecreased skin turgor, dry mucous membranesWeight gainThirst, weight lossSlow, bounding pulse; high blood pressureRapid, weak, thready pulse, low blood pressure, and orthostatic hypotensionLethargy, possible seizuresFatigue, weakness, dizziness, possible stuporPulmonary congestion, cough, ralesIncreased body temperatureLaboratory values:Laboratory values: Decreased hematocrit Increased hematocrit Decreased serum sodium Increased electrolytes (or variable) Urine: low specific gravity, high volume Urine: high specific gravity, low volume1.
