RN MedSurg Final Review 2022 (Answered) Complete Verified Solution Perfusion Circulation of blood within an organ or tissue in adequate amounts to meet current needs of the cells. peripheral arterial disease (PAD) disease of the arteries in the arms and legs, resulting in narrowing or complete obstruction of the artery signs and symptoms of peripheral arterial disease Intermittent claudication, pain at rest, tightening pressure in calves or buttocks, and ischemic changes. BP in the effected extremity is lower. Pallor with elevation, rubor when dependent. Peripheral Venous Disease (PVD) damage, defects or blockage in the veins that carry blood from the hands and feet to the heart signs and symptoms of peripheral venous disease - ruddy, cyanotic, brownish pigmentation - edema usually present, better with elevation - normal nails - normal pulses - warm - moist at bony ankle Ted hose, compression stockings, anti-embolic hose special stocking used to help prevent swelling and blood clots and to aid circulation (aka elastic or compression stockings) Plavix (clopidogrel) Antiplatelet Buerger's disease A condition in which the blood vessels, especially those supplying the legs, are constricted whenever nicotine enters the bloodstream, the ultimate result being gangrene and amputation. Raynaud's disease a peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress high cholesterol Hyperlipidemia (HLD) Atherosclerosis condition in which fatty deposits called plaque build up on the inner walls of the arteries respiratory acidosis A drop in blood pH due to hypoventilation (too little breathing) and a resulting accumulation of Co2. respiratory alkalosis Arise in blood pH due to hyperventilation (excessive breathing) and a resulting decrease in CO2. metabolic alkalosis elevation of HCO3- usually caused by an excessive loss of metabolic acids metabolic acidosis decreased pH in blood and body tissues as a result of an upset in metabolism S/S of metabolic acidosis Changing leves of consciousness, ranging from fatigue, & confusion to stupor & coma, headache, vomiting & diarrhea, anorexia, muscle weakness & cardiac dysrhythmias. S/S of metabolic alkalosis observe LOC decreased K levels muscle cramps and life threatening arrhythmias S/S of respiratory acidosis Headache Restlessness Mental status changes, such as drowsiness and confusion Visual disturbances Diaphoresis Cyanosis as the hypoxia becomes more acute Hyperkalemia Rapid, irregular pulse Dysrhythmias leading to ventricular fibrillation S/S of respiratory alkalosis lightheaded, faint, peri-oral numbness, numbness and tingling in fingers and toes acid-base balance equilibrium between acid and base concentrations in the body fluids cardon dioxide Product of metabolism Cells bicarbonate buffer system CO2 (g)+ H2O(l)↔H2 CO3 (aq)↔H+ (aq)+HCO3- (aq) -Blowing off CO2 (hyperventilation) decreases levels of CO2 which causes reaction to shift left consuming H+ and reducing H+ in the blood making pH less acidic -mechanism that deals w/ acidemia (excess H+ in blood) COPD (chronic obstructive pulmonary disease) disease with enlarged lung spaces, usually from smoking can cause shortness of breath S/S of COPD -Dyspnea -SOB -Clubbing of finger nails -Barrel chest -Cough -Crackles and wheezing -Low O2 sat -shallow respirations
