Study Notes

Microbial Count Standards

AAMI standard for conventional dialysis requires total microbial count to be less than 200 CFU/mL.
AAMI standard for dialysate specifies a microbial count of less than 100 CFU/mL.

Electrolyte Management

Abnormal potassium levels can lead to cardiac arrhythmias and even be fatal.
Hyperkalemia symptoms may include numbness and tingling.

Interdialytic Weight Gain

Acceptable interdialytic weight gains range from 3-5% of target weight (TW).

Infection and Access

Numbness and tingling are not signs of infected access.
Signs of infection include fever, swelling, redness, and tenderness.

Aseptic Techniques

Asepsis is the absence of disease-causing organisms.
Infection control requires using gloves when handling hemodialysis machinery.

Dialysis Equipment and Procedures

Dialysate pH is maintained between 6.9 and 7.6.
Conductivity testing of dialysate should be conducted; if it fails, notify the equipment technician.

Patient Interaction and Education

For visually impaired patients, describe the activities in the environment.
Refer patients expressing feelings of loneliness to a social worker.

Hemodialysis Complications

Monitor for infiltration when a patient experiences swelling at the venous needle site.
Hypotension can occur towards the end of dialysis treatments, indicated by dizziness and nausea.

Blood Parameters and Monitoring

Predialysis BUN levels should be lower than post-dialysis levels to confirm correct sampling.
Normal albumin levels are crucial as low levels are associated with higher hospitalization rates.

Ultrafiltration and Fluid Management

The ultrafiltration rate is determined by the volume of fluid removed divided by treatment time.
Excess fluid causes symptoms like hypertension and shortness of breath.

Emergency Responses

In cases of cardiac arrest, the first step is to call for assistance.
When air bubbles are detected in the circuit, clamp the venous line immediately.

Education and Training

Certification is a requirement by CMS for dialysis technicians.
Continued education reinforces necessary patient knowledge and compliance with protocols.

Kidney Function and Dialysis Efficacy

Nephron, the functional unit of the kidney, consists of glomeruli and tubules.
Urea Reduction Ratio (URR) target is a ratio greater than 65%, highlighting the efficacy of dialysis.

Miscellaneous

Use of normal saline before treatment helps remove air from the circuit.
Blood flow rate decreases diffusion rates during dialysis treatment.
