Document Summary
Osmotic fluid shifts - look at the patient. Skin turgor, fluid perfusion; chapped lips, don"t have to use the bathroom, when you do pee it"s dark and stinks: changes in urine output. Regardless of age, intake and output must be a careful. Increased (bounding) pulse - a lot stronger and harder. Decreased capillary colloidal osmotic pressure (r/t decreased proteins) Generalized edema - looks puffy all over; maybe have bp issues. Obstruction to lymph flow - edema around lymph nodes. Decreased diffusion of oxygen, nutrients, and waste in that area - so no shots or iv into edematous tissue - they would have tissue damage. If lungs cant get rid of co2, might have major lung disease like copd, or asthma, or have a cns depression (brain problem) Happens when you can"t breathe enough - not getting rid of enough co2: might have upper airway obstruction or chest wall problem like pneumothorax or broken ribs, manifestations - restless, headache, flushed skin.
