1. Which of the following is the primary function of the kidneys?
A. Produce insulin
B. Filter waste from the blood
C. Store bile
D. Produce red blood cells
B. Filter waste from the blood
The kidneys’ main role is to remove waste and excess fluids from the
blood, forming urine.
2. What is the normal range for adult blood pressure?
A. 120/80 mmHg
B. 140/90 mmHg
C. 100/60 mmHg
D. 160/100 mmHg
A. 120/80 mmHg
A normal adult blood pressure is typically around 120/80 mmHg;
values above this may indicate hypertension.
3. Which type of dialysis uses the patient’s peritoneum as a filter?
A. Hemodialysis
B. Peritoneal dialysis
, C. Continuous renal replacement therapy
D. Ultrafiltration
B. Peritoneal dialysis
Peritoneal dialysis involves instilling dialysis fluid into the peritoneal
cavity, using the peritoneal membrane to filter waste.
4. During hemodialysis, what is the function of the dialyzer?
A. Measure blood pressure
B. Filter blood
C. Infuse medications
D. Monitor heart rate
B. Filter blood
The dialyzer acts as an artificial kidney, removing waste and excess
fluids from the blood.
5. What is the most common vascular access for long-term
hemodialysis?
A. Central venous catheter
B. Arteriovenous fistula
C. Arteriovenous graft
D. Peripheral IV line
B. Arteriovenous fistula
AV fistulas are preferred for long-term dialysis because they have
lower infection rates and last longer than catheters or grafts.
6. Which electrolyte is most closely monitored to prevent cardiac
arrhythmias in dialysis patients?
A. Sodium
B. Potassium
C. Calcium
D. Chloride
,B. Potassium
High or low potassium levels can trigger life-threatening arrhythmias,
making careful monitoring essential.
7. Which of the following is a common complication during dialysis?
A. Hypotension
B. Hypertension
C. Hyperglycemia
D. Hypothermia
A. Hypotension
Sudden drops in blood pressure during dialysis are common due to
rapid fluid removal.
8. What is the primary purpose of heparin during dialysis?
A. Reduce blood pressure
B. Prevent clotting in the dialyzer
C. Increase filtration rate
D. Enhance patient comfort
B. Prevent clotting in the dialyzer
Heparin is an anticoagulant used to prevent blood from clotting while
circulating through the dialysis machine.
9. Which type of dialyzer membrane is synthetic?
A. Cuprophane
B. Polyethersulfone
C. Cellulose
D. Cotton
B. Polyethersulfone
Synthetic membranes like polyethersulfone provide better
biocompatibility and solute clearance than traditional cellulose
membranes.
, 10. What is uremia?
A. High blood sugar
B. Accumulation of waste products in the blood
C. Low blood pressure
D. Electrolyte imbalance
B. Accumulation of waste products in the blood
Uremia occurs when kidneys cannot filter waste efficiently, leading to
toxic buildup.
11. Which of the following is a sign of infection at a vascular
access site?
A. Bruising
B. Redness, swelling, and warmth
C. Dry skin
D. Low blood pressure
B. Redness, swelling, and warmth
These are classic signs of infection and should be reported
immediately.
12. The dialysate fluid’s main function is to:
A. Infuse medications
B. Remove waste and excess electrolytes
C. Increase blood pressure
D. Prevent infection
B. Remove waste and excess electrolytes
Dialysate contains a specific electrolyte composition that allows
diffusion of waste products from blood into the fluid.
13. Which of the following is considered a sterile procedure in
dialysis?
A. Measuring blood pressure
