Prescription Verification and Treatment Setup Checks
Key Takeaways
- The dialysis prescription controls treatment time, dialyzer, blood flow, dialysate, ultrafiltration, anticoagulation, and other ordered settings.
- Machine setup must match the current prescription, not memory or a previous treatment.
- Dialysate checks, alarm tests, bloodline setup, dialyzer selection, and prime status are verified before connection.
- Any mismatch, failed check, or unclear order must be corrected or escalated before treatment starts.
Match the treatment to the order
The prescription is the authorized plan for dialysis. It may include treatment time, dialyzer, blood flow rate, dialysate flow rate, dialysate potassium and calcium, bicarbonate, sodium profile if ordered, temperature, target weight, UF goal, anticoagulation protocol, and special precautions. A technician does not change these independently.
Verification starts with the right patient and the current prescription. Do not rely on memory, routine, or what the patient usually receives. Patients can have temporary prescription changes after labs, hospitalization, access problems, blood pressure issues, or provider review.
Setup checks include the correct dialyzer and bloodlines, intact packaging, expiration dates, proper priming, secure connections, correct concentrate, correct dialysate bath, machine alarm readiness, and required independent checks such as conductivity and pH according to facility policy. The result must be within acceptable limits before treatment begins.
| Setup item | What to compare |
|---|---|
| Patient identity | Treatment record and prescription |
| Dialyzer and bloodlines | Ordered type and facility policy |
| Dialysate bath | Current order and concentrate label |
| UF goal and time | Weight data, prescription, and policy |
| Safety checks | Machine display and independent device results |
A mismatch is not a small clerical problem. Wrong dialysate, wrong patient, wrong dialyzer, wrong heparin status, or a failed safety check can injure a patient. Stop the setup process, keep the patient safe, and notify the RN or qualified staff according to policy.
Patient requests do not replace orders. If a patient asks to shorten treatment, remove extra fluid, skip ordered heparin, change dialysate, or use a different access plan, report the request. The treatment can only be changed through the proper clinical process.
Good documentation shows that required checks were completed and abnormal findings were handled. Chart exact values when required, such as conductivity or pH, and record notifications and corrective actions. On the exam, the safest answer is usually to verify before connecting and clarify before treating.
The current prescription lists a 2 potassium dialysate bath, but the machine is set up with a 3 potassium bath. What should the technician do?
A patient asks to shorten today's treatment by one hour because of an appointment. Which action is within safe CCHT practice?
The independent dialysate conductivity check is outside the acceptable range before treatment. What is the safest response?
