CCHT practice exam questions solved
correctly.
AAMI Chemical Analysis of water used for hemodialysis is tested -
Ans>> >> annually
A dialysis technician observes a drop of blood on the surface of a
patient's hemodialysis machine. Which of these actions should
the dialysis technician take? - Ans>> >> Clean the machine
surface immediately
A dialysis technician observes all of the below on the treatment
floor, which one poses an environment risk? - Ans>> >> About
one ounce (30 ml) fluid is on the floor
A fistula connects - Ans>> >> An artery to a vein
,A marker used to determine the middle molecule clearance of a
dialyzer is - Ans>> >> Vitamin B12
A mixed- bed DI tank contains - Ans>> >> Cations and anions
What is diffusion? - Ans>> >> The movement of particles across
a semipermeable membrane from an area of higher solute
concentration to an area of lower solute concentration, until the
concentration on both sides of the membrane is equal
What is filtration? - Ans>> >> The process of passing fluid
through a filter or semipermeable membrane
What is epogen? - Ans>> >> A medication (synthetic
erythropoietin) used to stimulate production of red blood cells
How long can a used dialyzer sit out before reprocessing? -
Ans>> >> 2 hours
How long can a reprocessed dialyzer sit out to dry before use? -
Ans>> >> 11 hours
What is a reused dialyzer shelf life? - Ans>> >> 14 days
What is a reuse dialyzer (TCV) percentage - Ans>> >> 80%
,What does AAMI stand for? - Ans>> >> Association for the
Advancement of Medical Instrumentation
The base used to maintain an acceptable dialysate pH(acid/base
balance). A buffer - Ans>> >> Bicarbonate
What is BUN? - Ans>> >> Blood urea nitrogen, the end product of
protein metabolism
What is a aneurysm? - Ans>> >> A ballooning of the AV fistula,
sometimes caused by improper rotation of needle sites
An irregular heart beat - Ans>> >> dysrhythmia
Difficulty breathing - Ans>> >> Dyspnea
Abnormal accumulation of fluid in the body tissues causing
swelling. Fluid accumulated in the interstitial space - Ans>> >>
Edema
What is Epogen given for? - Ans>> >> A medication (synthetic
erythropoietin) used to stimulate production of red blood cells
What is extracorporeal circuit? - Ans>> >> The circuit "outside
body" that carries blood from the patient through dialyzer and
, back to the patient. The dialyzer and blood lines make up the
circuit
What is filtration? - Ans>> >> The process of passing fluid
through a filter or semipermeable membrane.
What is glomerulus? - Ans>> >> A tuft of capillaries in the
nephron that act as filters to remove waste products, fluid and
excess electrolytes from the blood as it passes through the
kidney.
The measurement of the percentage of red blood cells in a sample
of whole blood. This measure is affected by vascular volume. -
Ans>> >> Hematocrit (HCT)
A localized mass of clotted or partially clotted blood confined
within an organ or tissue, which may be discolored (bruised). -
Ans>> >> Hematoma
A protein that carries oxygen from the lung to the body tissue and
trAns>> ports carbon dioxide from the tissues to the lungs. -
Ans>> >> Hemoglobin (HB)
What is the rupture of red blood cells? ( lysis is cell rupture) -
Ans>> >> Hemolysis
