In the urinary tract, urine flows from:
Kidneys to urethra to ureters to bladder
Kidneys to bladder to ureters to urethra
Kidneys to ureters to bladder to urethra
Kidneys to ureters to urethra to bladder
The goals of hemodialysis are to replace some functions of the kidney, and include:
· Removal of waste products
· Regulation of fluid balance
· Correction of electrolyte and acid/base imbalance
True
False
The hemodialysis machine:
Mixes and monitors dialysate
Pumps and monitors the patients blood
Monitors patient safety
All of the above
The physician determines the hemodialysis prescription, which includes:
Treatment time, type of dialyzer
Blood and dialysate flow rates
Dialysate composition
Needle size, medications
All of the above
Access to the patient's bloodstream is necessary for hemodialysis. The most reliable, problem-free and longest-lasting hemodialysis vascular access is:
Arteriovenous graft (AVG) (graft)
Arteriovenous fistula (AVF) (fistula)
Central venous catheter (CVC) (catheter)
Femoral catheter
Dialysate is a precise mixture of treated water, bicarbonate concentrate and acid concentrate which is:
Hypotonic
Isotonic
Hypertonic
Normotonic
Hypotonic dialysate is one cause of:
Hemolysis
Hemorrhoids
Hemoconcentration
Hemmorhage
The RN may vary prescribed amounts of potassium and calcium in dialysate based on the patient's needs
True
False
Water used for hemodialysis is treated to remove harmful contaminants and is:
Sterile
Routinely tested by CMS
Not sterile
Routinely tested by AAMI
The dialyzer membrane is semipermeable because:
Electrolytes pass through it
Water and wastes pass through it
Blood cells don't pass through it
Bacteria and viruses don't pass through it
All of the above
Diffusion is:
The movement of water from an area of lesser concentration to an area of higher concentration across a semipermeable membrane
The movement of solute from an area of lower concentration to an area of higher concentration across a semipermeable membrane
The movement of water from an area of higher concentration to an area of lower concentration across a semipermeable membrane
The movement of solute from an area of higher concentration to an area of lower concentration across a semipermeable membrane
Osmosis is:
The movement of water from an area of lesser concentration to an area of higher concentration across a semipermeable membrane
The movement of solute from an area of lesser concentration to an area of higher concentration across a semipermeable membrane
The movement of water from an area of higher concentration to an area of lesser concentration across a semipermeable membrane
The movement of solute from an area of higher concentration to an area of lesser concentration across a semipermeable membrane
During hemodialysis, wastes are removed from the patient's blood by:
Osmosis
Diffusion
Filtration
Ultrafiltration
Removal of waste during hemodialysis is enhanced by:
A. Greater permeability of the membrane (larger pores)
B. More membrane surface area
C. Countercurrent flow of dialysate and blood
D. Lower dialysate temperature
E. All but D
During hemodialysis, excess fluid is removed by:
Osmosis
Diffusion
Filtration
Ultrafiltration
The difference in pressure that results as fluid moves across the dialyzer membrane is called:
Venous pressure (VP)
Transmembrane pressure (TMP)
Arterial pressure (AP)
Dialysate pressure (DP)
During hemodialysis, increasing transmembrane pressure (TMP) is usually caused by:
Clotting of the dialyzer fibers
Clotting of the venous chamber
Clotting of the arterial chamber
Clotting of the patient's access
By FKC standards, which hemodialysis spKt/V is considered adequate?
1.0
1.1
1.2
1.4
Factors that enhance dialysis adequacy include:
A. Good vascular access function
B. Optimal heparinization
C. Proper priming of the extracorporeal circuit
D. All of the above
E. All but B
Adequacy of the hemodialysis treatment would be adversely affected by:
The presence of air in the dialyzer
Using the prescribed dialyzer
Maintaining blood flow and dialysate flow rates
Completing the full treatment
