PCT -Davita Test Questions with Correct Answers Already Passed
Ultrafiltration (UF) - Answers FLUID PUSHED through the semipermeable (SPM) membrane
Provides fluid balance
Convection - Answers SOLUTES DRAGGED across SPM along with fluid
(Toxins and electrolytes)
Diffusion - Answers PARTICLES moves from area of HIGH to LOW concentration
The hotter the acid concentrate gradient the faster the diffusion
Osmosis - Answers FLIUD moves from area of LOW to HIGH concentration
Acid concentrate / dialysate - Answers Provides concentration gradient for diffusion
Cleans blood in dialyzer by removing waste
(Made up of h2o electrolytes and salts)
Bicarb - Answers BUFFERS the acid concentrate/dailysate
Normalized body PH in pts blood
Dialysate - Answers Composed of purified h2o acid and bicarb
Dialysate compartment of dialyzer IS sterile
PH potential of hydrogen - Answers Normal range: 7.35 - 7.45
Uremia - Answers Buildup of waste in the blood due to kidney failure
Affects all body systems
Sodium - Answers REGULATES: Fluid volume, fluid balance, blood pressure
Requirements KDOQI: 2.3 grams (2,300 mg) per day
KDOQI - Answers Kidney Disease Outcomes Quality Initiative
HypERtension - Answers High blood pressure >180/>100
Leads to LEFT ventricular hypertrophy
HypOtension - Answers low blood pressure persistently lower than 90/60 mm Hg
Pericarditis - Answers Inflammation of the pericardial sac surrounding the heart
, Included in tx: more frequent dialysis, decrease or stop heparin
Why are dialysis pts Anemic? - Answers Life span of RBC is 60 days/half of normal
120
Mature AFV - Answers KDOQI rule of 6
AFV is at RX BFR

Interdialytic weight gain calculation - Answers Pre weight - last post weight
Ultra filtration (UF) goal calculation - Answers Pre weight - target weight + NS prime and rinse back +
weight oral intake, infusions
UF rate (UFR) calculation - Answers (Pt RX/ Dr ordered)
UF goal divided by TX hours
Fluid replacement calculation - Answers Pre weight - target weight = fluid deficit
+ NS prime and rinse back + oral intake, infusions =
Amount of fluid to replace
divided by total TX time =
fluid replacement per hour
