,Q1. During a hemodialysis treatment, the venous pressure alarm sounds and the
venous pressure reading is 300 mmHg. The technician checks the access and finds no
kinks or disconnections. What is the most likely cause of this elevated venous
pressure?
A. Arterial needle infiltration
B. Venous needle infiltration
C. Clotting of the dialyzer
D. Inadequate blood flow from the access
Correct Answer: B. Venous needle infiltration
Rationale: Elevated venous pressure with a patent access and no kinks typically indicates
increased resistance downstream of the venous drip chamber, most commonly due to
venous needle infiltration or stenosis. Arterial infiltration would cause a low arterial
pressure alarm, dialyzer clotting would increase both arterial and venous pressures, and
inadequate blood flow would cause a low arterial pressure alarm.
Why Wrong:
A - Arterial needle infiltration would cause a low arterial pressure and often a high
venous pressure, but the question specifies the access is checked and no infiltration is
mentioned.
C - Clotting of the dialyzer would cause a progressive rise in both arterial and venous
pressures, not isolated venous pressure elevation.
D - Inadequate blood flow from the access would result in a low arterial pressure
alarm, not high venous pressure.

Monitoring.
Q2. A patient on hemodialysis has a Kt/V of 1.2. The prescribed treatment time is 3.5
hours, but the patient frequently stops treatment early. Which of the following
adjustments would most effectively improve dialysis adequacy without increasing
treatment time?
A. Increase the dialysate flow rate from 500 to 800 mL/min
B. Switch from a low-flux to a high-flux dialyzer
C. Increase the blood flow rate from 300 to 400 mL/min
D. Increase the dialysate sodium concentration
Correct Answer: C. Increase the blood flow rate from 300 to 400 mL/min
Rationale: Kt/V is directly proportional to blood flow rate (Qb) and dialysate flow rate
(Qd), but increasing Qb has a more significant impact on urea clearance than increasing
Qd, especially at higher Qd. High-flux dialyzers increase clearance of larger molecules
but not necessarily urea. Dialysate sodium affects sodium balance, not urea clearance.
Page 3
, Why Wrong:
A - Increasing dialysate flow from 500 to 800 mL/min yields only marginal gains in
urea clearance because the dialysate is already in excess relative to blood flow.
B - High-flux dialyzers improve clearance of middle molecules but not significantly
for small solutes like urea when compared to low-flux at the same blood flow.
D - Dialysate sodium concentration does not affect urea clearance; it influences
sodium balance and intradialytic symptoms.

Adequacy.
Q3. A hemodialysis technician notices that the water treatment system's product
water has a high bacterial count. According to AAMI standards, what is the
maximum allowable bacterial count for dialysis water?
A. 100 CFU/mL
B. 200 CFU/mL
C. 50 CFU/mL
D. 500 CFU/mL
Correct Answer: A. 100 CFU/mL
Rationale: AAMI RD52:2004 and updated standards specify that the maximum allowable
bacterial count in water used for dialysis is 100 CFU/mL, with an action level of 50
CFU/mL. Endotoxin levels must be below 0.25 EU/mL.
Why Wrong:
B - 200 CFU/mL exceeds the AAMI allowable limit.
C - 50 CFU/mL is the action level, not the maximum allowable limit.
D - 500 CFU/mL is far above the standard.

RD52:2004.
Q4. A patient receiving hemodialysis develops muscle cramping during the latter half
of the treatment. Which of the following interventions is most appropriate to relieve
the cramping?
A. Administer a bolus of normal saline
B. Decrease the ultrafiltration rate
C. Increase the dialysate temperature
D. Administer hypertonic saline
Correct Answer: D. Administer hypertonic saline
Rationale: Muscle cramps during hemodialysis are often due to hypovolemia and
hyponatremia. Hypertonic saline (e.g., 23.4% NaCl) is effective in relieving cramps by
increasing plasma osmolality and drawing fluid into the vascular space. Normal saline
