DaVita RN Final Exam Guide Q&A | Verified 2025/2026 Content | Exam-Aligned |
Prepared for Academic & Clinical Excellence
1. What is the primary nursing action when a dialysis patient presents with
hypotension during treatment?
a) Increase ultrafiltration rate
b) Administer a saline bolus and reduce ultrafiltration
c) Continue treatment as prescribed
d) Increase blood flow rate
b) Administer a saline bolus and reduce ultrafiltration
Rationale: Hypotension often results from rapid fluid removal. A saline bolus restores volume,
and reducing ultrafiltration prevents further drop in blood pressure.
2. Which electrolyte imbalance is most likely to cause cardiac arrhythmias
in dialysis patients?
a) Hyponatremia
b) Hyperkalemia
c) Hypocalcemia
d) Hypermagnesemia
b) Hyperkalemia
,Rationale: Elevated potassium levels disrupt cardiac conduction, increasing the risk of
arrhythmias.
3. What is the nurse’s role in managing a patient with a clotted
arteriovenous (AV) fistula?
a) Attempt declotting with heparin
b) Notify the nephrologist and avoid cannulation
c) Increase blood flow rate
d) Use the fistula for dialysis
b) Notify the nephrologist and avoid cannulation
Rationale: A clotted fistula is non-functional and requires specialist intervention; cannulation
risks further damage.
4. What is the purpose of assessing a patient’s dry weight before dialysis?
a) To determine medication dosage
b) To guide fluid removal targets
c) To assess infection risk
d) To monitor Kt/V
b) To guide fluid removal targets
Rationale: Dry weight helps set ultrafiltration goals to achieve optimal fluid balance.
5. What is the most common cause of bacteremia in dialysis patients with
central venous catheters (CVCs)?
a) Poor nutrition
b) Catheter-related bloodstream infection
c) Inadequate dialysis time
d) Improper dialysate composition
b) Catheter-related bloodstream infection
Rationale: CVCs are a primary source of infection due to direct vascular access.
6. What should a nurse do if a dialysis machine triggers a blood leak alarm?
a) Ignore the alarm and continue treatment
b) Stop the blood pump and clamp lines
c) Increase ultrafiltration rate
d) Adjust dialysate flow
b) Stop the blood pump and clamp lines
Rationale: A blood leak alarm indicates a potential dialyzer membrane rupture; stopping the
pump prevents blood loss.
7. What is the nurse’s priority action for a patient experiencing a seizure
during dialysis?
a) Continue dialysis and monitor
b) Discontinue dialysis and protect the patient
c) Administer heparin
d) Increase blood flow rate
, b) Discontinue dialysis and protect the patient
Rationale: Stopping dialysis and ensuring patient safety prevents injury during a seizure.
8. According to DaVita protocol, how is a fever defined in a dialysis patient?
a) Temperature >99°F without symptoms
b) Temperature >100°F or 2°F above baseline with symptoms
c) Temperature >98°F with chills
d) Temperature >101°F without symptoms
b) Temperature >100°F or 2°F above baseline with symptoms
Rationale: This definition ensures early detection of potential infections.
9. What is the nurse’s responsibility when a patient requests to terminate
dialysis early?
a) Allow it without documentation
b) Assess the patient and document the decision
c) Increase ultrafiltration to compensate
d) Deny the request
b) Assess the patient and document the decision
Rationale: Early termination requires clinical assessment and thorough documentation for
safety and compliance.
10. What is the likely cause of a high venous pressure alarm during dialysis?
a) Low blood flow rate
b) Clotting in the venous drip chamber
c) Loose needle connection
d) High ultrafiltration rate
b) Clotting in the venous drip chamber
Rationale: Clotting obstructs blood return, increasing venous pressure.
11. What is the purpose of reverse osmosis in the dialysis water treatment
system?
a) To add electrolytes to dialysate
b) To remove contaminants from water
c) To monitor water temperature
d) To calibrate dialysis machines
b) To remove contaminants from water
Rationale: Reverse osmosis purifies water to ensure safe dialysate for patient use.
12. What is the nurse’s action if a patient reports chest pain during dialysis?
a) Continue treatment and monitor
b) Stop dialysis and assess the patient
c) Increase blood flow rate
d) Administer heparin
b) Stop dialysis and assess the patient
Rationale: Chest pain may indicate a cardiac event, requiring immediate cessation and
assessment.
