,1.
A patient presents with muscle cramps during hemodialysis. What is
the most likely physiological cause?
A. Hyperglycemia
B. Rapid fluid removal
C. Anemia
D. Air embolism
ANS: B
Rationale: Rapid ultrafiltration can cause intravascular volume
depletion, leading to muscle cramps.
2.
A patient’s pre-dialysis potassium is 6.7 mEq/L. What is the primary
concern during treatment?
A. Hypervolemia
B. Hypotension
C. Cardiac arrhythmias
D. Bleeding
ANS: C
Rationale: Hyperkalemia is associated with life-threatening cardiac
arrhythmias.
3.
If a patient develops chest pain and hypotension during dialysis, your
immediate action is to:
A. Increase blood flow rate
B. Decrease ultrafiltration rate
C. Stop dialysis and call for help
D. Give oral fluids
ANS: C
Rationale: Chest pain with hypotension is a medical emergency; stop
dialysis and initiate emergency protocols.

, 4.
A patient with AV fistula has difficulty achieving hemostasis post-
needle removal. What underlying problem might this indicate?
A. High phosphate levels
B. Inadequate anticoagulation
C. Fistula infection
D. Prolonged bleeding time
ANS: D
Rationale: Prolonged bleeding after needle removal can indicate a
coagulopathy, commonly seen in uremia.
5.
While monitoring the dialyzer, you notice pink or red tinged effluent.
What does this most likely suggest?
A. Air embolism
B. Blood leak
C. Clotting in the dialyzer
D. Dialysate contamination
ANS: B
Rationale: Red or pink effluent is a classic sign of a dialyzer blood
leak.
6.
A patient develops disequilibrium syndrome. The initial step to take
is:
A. Increase dialysate flow
B. Slow or stop dialysis
C. Administer glucose
D. Reduce dialysate temperature
ANS: B
Rationale: Dialysis disequilibrium syndrome requires slowing or
stopping the treatment to prevent further CNS symptoms.
7.
A patient is non-responsive immediately post-dialysis. What is the
