DAVITA EXAM PREP QUESTIONS WITH CORRECT ANSWERS GRADED TO PASS

What is the correct procedure for residual bleach testing after chemical disinfection loops and equipment fluid pathways? - residual bleach testing is performed after bleach disinfection and prior to use To avoid bacterial proliferation rapid reproduction within the extracorporeal circuit once primed the recirculation of saline within the dialyzer and blood lines should not exceed _______________ prior to initiating the hemodialysis treatment - 2 hours Why is strikethrough of an external pressure transducer protector of concern? - fluid could have entered the machine and contaminated the internal pressure transducer protector providing a reservoir for microorganism and causing subsequent patient blood infections Machine alarm test are performed - before the initiation of each patient treatment Which is a true statement regarding the monitoring testing and verification of conductivity prior to each patient treatment for all fresenius machine models and the b braun system - the b braun machine conductivity is verified on the endle machine screen manual conductivity testing with an independent meter must be within +/-0.4 ms of the theoretical conductivity tcd for both the b braun and fresenius machines What is the safe range for dialysate ph - between 6.9 and 7.6 The transport mechanism when particles move from an area of higher solute concentration to an area of lower solute concentration is called - diffusion If a patient with acute kidney injury aki dialyzes in the outpatient facility one task of the patient care teammate is to monitor blood pressure and weight closely why is this important - hypokalemia and hypotensive episodes can cause renal ischemia and can further damage the kidneys During dialysis the movement of bicarbonate from the dialysate into the blood - helps normalize body ph Ultrafiltration is defined as - controlled fluid removal by manipulation of hydrostatic pressure Your role and anemia management includes - rinsing back as much of the patient's blood as you can at the termination of each treatment A common reason of how hepatitis b is transmitted from patient to a healthcare worker is - needlestick injuries Hemodialysis patients are at increased risk for contracting hepatitis b - true To prepare a 1:100 bleach solution you would - add 1 part bleach to 99 parts water Handwashing at a designated clean sink would be performed for a minimum of - 20 seconds Contact transmission is the most important route through which infections are spread contact transmission is defined as - transmission of micro organisms through healthcare workers hands According to the policy and procedure gowns - must be fully snapped up or tied at the neck and waist and wrist covered Appropriate personal protective equipment ppe should be worn whenever there is a potential for contact with blood or bodily fluids hazardous chemicals contaminated equipment and environment - gloves gowns and face mouth nose and eye protection A 1:10 bleach solution is used to - clean up visible blood or gross blood spills Timmy is caring for a patient with active c diff infection are required to - perform hand hygiene using only soap and water I sudden decrease in blood pressure of equal to or greater than _____________ can be an indication that the patient is losing intravascular fluid too quickly - 20 mmhg Because a pre-pump arterial pressure that becomes too negative can cause hemo lysis davita policy states that the arterial pressure must not exceed - -260 mmhg What needle size should be used for a blood flow rate bfr a prescription of 400 ml/min - 15 gauge Once rinse back is complete what should be done before removing a patient's venous needles - check the patient's blood pressure
