Study Notes

AAMI Standards and Testing

AAMI Chemical Analysis of water used for hemodialysis is conducted annually.
AAMI standards for microbial count in dialysate must not exceed 200 CFU/mL.
Endotoxin levels according to AAMI standards are less than 2 EU/mL.

Patient Interactions and Care

Describe activities in the environment when interacting with blind patients to ensure comfort.
Refer patients expressing feelings of loneliness or depression to a social worker for further support.
Always clean the surface of the hemodialysis machine immediately upon observing blood.

Environmental Safety

A one-ounce (30mL) fluid spill on the floor poses an environmental risk on the treatment floor.

Patient Anatomy and Treatment

A fistula connects an artery to a vein, essential for hemodialysis access.
An infiltration is suspected when there is swelling and rising venous pressure at the needle site during treatment.
The nephron comprises a glomerulus and a tubule system, integral for kidney function.

Dialysis Considerations

First dialysis treatment patients are at risk for dialysis disequilibrium syndrome.
Albumin levels reflect a patient’s nutritional status, significant for overall health in dialysis patients.
Acceptable interdialytic weight gains are typically between 3% to 5% of estimated dry weight (EDW).

Electrolyte Levels and Monitoring

High potassium levels can cause serious cardiac arrhythmias and can be life-threatening.
Foods high in potassium include bananas, which should be limited in a dialysis patient’s diet.

Heart Rate and Conditions

A heart rate of 54 beats/minute indicates bradycardia; 104 beats/minute indicates tachycardia.
Bradycardia and tachycardia are important vital signs to monitor in dialysis patients.

Documentation and Practice

Never document actions performed by someone else; always record your own interventions.
Documenting a teammate’s administration of saline is not permissible.

Miscellaneous

Vitamin B12 is used as a marker to determine middle molecule clearance in dialysis.
Cations and anions are present in a mixed-bed DI tank, critical for water quality in dialysis.
Common phosphate binders include Renagel and Phos-Lo; Tums is not a phosphate binder.

Certification and Regulations

Federal regulation requires all dialysis technicians to be certified by April 15, 2010.
