Question 2: Which of the following dialyzer is currently used
Answer:
Hollow tube Question 3: Which of the following kidney structures connects with and delivers urine directly to the ureter
Answer:
Pelvis Question 4: Which of the following precautions must a facility take to protect workers from exposure to toxic chemicals
Answer:
Employee training and availability of MSDS sheets
Question 5: The purpose of priming the extracorporeal circuit with saline during setup is
Answer:
To remove sterilant, manufacturing residues or plasitizers before initiating treatment
Question 6: Diffusion is movement of particles
Answer:
From an area of higher concentration to an area of lower concentration Question 7: Dialysate that has too much sodium may cause patient injury. Too much sodium or hypernatremia can cause
Answer:
Headaches, high blood pressure, cramping, and shriveling of red blood cells Question 8: First use syndrome is a hypersensitivity reaction to a dialyzer. It is characterized by
Answer:
Back pain, anxiety, tachycardia, wheezing and circulatory collapse Question 9: A 58 year old patient who is blind comes for his first hemodialysis treatment accompanied by his wife. Which of these methods would the technician use to interact with the patient
Answer:
Describe the activities in the immediate environment
Question 10: Negative pressure is pressure created when
Answer:
Fluid is pulled through a restriction Question 11: During a hemodialysis treatment, the technician responds to a high venous pressure alarm. The tech should be aware that the most likely cause of alarm activation is?
Answer:
Kinking of blood lines
Question 12: The fistula was developed by
Answer:
Brescia and Cimino
Question 13: Treatment of hypotension includes
Answer:
Decreasing the UFR/TMP and placing the patient in the trendelenberg position
Question 14: Dialysate flow is monitored by the following monitors
Answer:
Conductivity Temperature Dialysate flow rate Question 15: Dialyzer are reprocessed before use to rinse out manufacturing residues and to
Answer:
Establish the original fiber bundle volume of the dialyzer and check for leaks Question 16: Describe the four types of anastomosis for internal arteriovenous fistula
Answer:
- Artery-side to vein-side anastomosis (side to side) this is easiest for a surgeon to construct
- Artery end to vein end anastomosis (end to end)diverts less blood from the patients hand, but it also
permits less blood flow through the access
- Artery end to vein side anastomosis (end to end) diverts less blood from the hand but with slightly
lower blood flow rates than the artery side to vein side anastomosis
- Artery side to vein end anastomosis (side to side) produces high blood flows with minimal
complications
Question 17: Large amounts of aluminum in water used for dialysis could cause
Answer:
Bone disease and anemia Question 18: Which of these functions of healthy kidneys can be replaced by dialysis
Answer:
- fluid removal
- waste removal
- electrolyte balance
Question 19: The components of the dialysis treatment that affect the clearance include
Answer:
Dialysate flow, time of treatment, dialyzer size, and blood flow rate Question 20: What is the most important safety monitor during a dialysis treatment
Answer:
The dialysis technician
Question 21: Edema is defined as
Answer:
An increase in the amount of extracellular tissues Question 22: Although dialysate delivery systems have a backup monitoring system it is critical that
Answer:
- The monitoring system be checked and calibrated on a schedule recommended by the manufacturer
- Conductivity and PH be verified by independent meters before each dialysis treatment and whenever
the dialysate is changed
- All alarm systems be tested prior to each dialysis treatment
Question 23: Endotoxin
Answer:
Toxin released during decomposition of bacterial cell walls
Question 24: Name two compartments of the dialyzer
Answer:
Blood and dialysate Question 25: An access in which there is a synthetic type material placed subcutaneously to join an artery in a vein is called
Answer:
