Question 1: For patients in whom the priming solution is to be discarded, what should the hemodialysis technician do next?

• connect the arterial and venous tubing before beginning dialysis
• connect the arterial tubing, and allow the priming solution to drain before connect the

venous tubing

• connect the blood lines only after the primer is discarded
• do none of the above

Answer:

• connect the arterial tubing, and allow the priming solution to drain before connecting the venous

tubing Question 2: Which type of arteriovenous fistula is likely to result in high blood flow with the fewest complications?

• artery side to vein side
• artery side to vein end
• artery end to being side
• artery end to vein end

Answer:

• artery side to vein end

Question 3: All of the following conditions are associated with chronic kidney failure EXCEPT:

• low hemoglobin
• hypoparathyroidism
• hyperkalemia
• hyperphosphatemia

Answer:

• Hypoparathyroidism

Question 4: The term "sieving coefficient of a membrane" refers to the:

• fraction of solute that passes through the membrane by convection
• amount of water required for solute drag through the membrane
• concentration of pores in the membrane
• size of the pores in the membrane

Answer:

• fraction of solute that passes through the membrane by convection

Question 5: The urea reduction ratio has which of the following properties?

• it requires measurement of both pre and post dialysis blood urea nitrogen
• it accounts for the production of urea during dialysis
• it allows calculation of the time needed for dialysis
• it allows calculation of urea removed by ultrafiltration

Answer:

• It requires measurement of both pre and post dialysis blood urea nitrogen

Question 6: A hemodialysis patient suddenly develops trouble breathing, hives, itching, and

hypotension. The most likely cause is:

• an air embolism
• an anaphylactic reaction
• angina
• disequilibrium syndrome

Answer:

• an anaphylactic reaction

Question 7: Dialysis machines control the rate of fluid removal by:

• volume control
• flow control
• either volume or flow control
• neither volume nor flow control

Answer:

• either volume or flow control

Question 8: The glomerular filtration rate is an important index of renal function and in the

normal adult is approximately:

• 50 mL/min/1.73 m2
• 75 mL/min/1.73 m2
• 125 mL/min/1.73 m2
• 200 mL/min/1.73 m2

Answer:

• 125 mL/min/1.73 m2

Question 9: All of the following substances are produced by the kidney EXCEPT:

• renin
• aldosterone
• erythropoietin
• calcitriol

Answer:

• Aldosterone

Question 10: To determine the most accurate clearance rate of a particular solute, one should:

• use water instead of blood
• use a large molecular weight molecule
• reduce the manufacture's stated rate by 10%
• measure the solute concentrations of blood going into and out of the dialyzer

Answer:

• measure the solute concentrations of blood going into and out of the dialyzer

Question 11: The ultrafiltration coefficient of a dialyzer refers to the:

• fluid that passes through the membrane in 1 hour
• pressure in the blood compartment needed to force fluid through the membrane
• pressure difference across the membrane
• fluid that passes through the membrane in 1 minute

Answer:

• fluid that passes through the membrane in 1 hour

Question 12: biocompatibility is best illustrated by:

• synthetic membranes that do not absorb blood proteins as well as cellulose membranes
• independence from protein absorption of the membrane
