resource is the - ANSWER-FDA Good Manufacturing Practices Act
How far should the sternum of an adult be depressed during cardiopulmonary
resuscitation (CPR) compressions? - ANSWER-1 1/2 inches
When handling dialysate effluent (liquid waste or sewage), staff should wear gloves,
masks, and eye protection because - ANSWER-The effluent is considered a
contaminated body fluid
A permanent tunneled catheter is an example of - ANSWER-External blood accesses
A system of water treatment that removes chloramines is called - ANSWER-Activated
carbon
Mechanical filtration of suspended particulate matter includes all of the following
EXCEPT - ANSWER-Carbon filters
The MOST common cause of death among hemodialysis patients is - ANSWER-
Cardiac complications
, Prepump arterial pressure monitoring is useful for - ANSWER-1. Monitoring access
function 2. Monitoring dialyzer clotting 3. Identifying potential hemolysis risk
As the technician is returning blood to the patient at a slow rate at the end of dialysis, it
is noted that the venous chamber has emptied and the venous line has filled with air.
The FIRST response should be to - ANSWER-Clamp the venous line and turn off the
blood pump
The major cause associated with the failure of the arteriovenous (AV) graft is -
ANSWER-Rejection
All the following conditions can cause alarm and result in no dialysate flow - ANSWER-
1. Dialysate pump failure 2. Inadequate water 3. Power failure
According to the Association for the Advancement of Medical Instrumentation (AAMI),
water used for the hemodialysis machine should NOT exceed an action level of -
ANSWER-50 CFU/mL

middle of a patient treatment can be reduced by - ANSWER-Putting deionization tanks
downstream of the water softener

urea - ANSWER-Creatinine, potassium, and phosphorus
The technician has tested the tap water for total chlorine and the level is zero. The
municipal water treatment plant tells the technician it does not use chlorine. The
