HEMODIALYSIS ANDERSON CCHT EXAM NEWEST 2026
ACTUAL EXAM| COMPLETE QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
GRADED A+ (BRAND NEW!!)
1. You are setting up a hemodialysis machine. After placing the
dialyzer and blood tubing, the next step is:
A) Start blood pump at 100 mL/min
B) Perform conductivity and temperature checks
C) Prime the extracorporeal circuit with saline
D) Attach patient to arterial and venous lines
Answer: C
Rationale: Priming removes air, sterilant, and wets the
membrane. Conductivity checks occur before priming.
2. The blood pump on a dialysis machine is calibrated to deliver
flow within which acceptable range?
1
, A) ±5% of set rate
B) ±10% of set rate
C) ±15% of set rate
D) ±20% of set rate
Answer: B
Rationale: AAMI standards allow ±10% variation (e.g.,
400 mL/min → 360–440 mL/min).
3. While priming, you see air bubbles trapped in the dialyzer
header. What should you do?
A) Start treatment — air detector will catch bubbles
B) Tap the dialyzer gently and continue saline flush
C) Discard the dialyzer and prime a new one
D) Increase saline flow to 500 mL/min
Answer: B
2
, Rationale: Tapping displaces trapped air. Aggressive
tapping can damage fibers; gentle is fine.
4. Which alarm would sound if the venous line becomes kinked?
A) Low venous pressure
B) High venous pressure
C) Conductivity alarm
D) Blood leak alarm
Answer: B
Rationale: Kinked venous line increases resistance → high
venous pressure alarm.
5. The conductivity alarm sounds with a reading of 12.8 mS/cm
(prescribed 14.0). The first action is:
A) Continue dialysis — alarm will reset
B) Check that concentrate A and B lines are in correct
containers
3
, C) Increase blood flow
D) Bypass conductivity meter
Answer: B
Rationale: Low conductivity often means empty concentrate
or wrong line placement. Never bypass.
6. The arterial pressure (pre-pump) reads −260 mmHg. Blood
flow is 450 mL/min. The correct action is:
A) Increase blood flow to 500
B) Decrease blood flow and assess access
C) Document and continue
D) Increase heparin
Answer: B
Rationale: Very negative pressure (>−250) risks hemolysis.
Reduce flow, check needles/access.
7. The venous pressure alarm is high. Which is NOT a cause?
