New cards
26

thrill (vibration under skin when palpate) bruit (swoosh sound when auscultated) positive for thrill and bruit

what do you assess for a fistula and graft? what do you chart?

injury/ cause happens

What is the first stage of ARF?

Stage 2, oliguric phase

Stage ARF? urine output--minimal to none (no output for 1 day or 2 days, hours) Labs: BUN and Creatine: Elevated Acid Base Imbalance: Metabolic Acidosis K, Mg, P are high GFR is decreased

Stage ARF? Urine output: massive amounts, usually at least 4000ml (kidneys will regain their ability to get rid of fluid but will not effectively filter) Greatest risk? -Electrolyte depletion, dehydration (pull lytes k, mg out, risky for patients. See cardiac dysrhythmia, muscle weakness, pain, cramp, chest pain)

New cards
65

Stage 4 , recovery phase

Stage ARF? output normalizes, balances intake Labs: mostly normal immediately. Gradually improve more as the body heals and regulates everything -lytes normal -BUN/ creatine normal
