a. Centers fork Medicare & Medicaid Services guidelines
b. dialysis center guidelines
c. technician's training
d. state regulations/ standards of practice

Although certified technicians should receive similar training, some states allow
technicians to cannulate accesses and to administer intravenous heparin, whereas

duties ( such as administering heparin), a dialysis center may further restrict the
technician's role

Answer b. 11 hours
Only one germicide may be used, but there are four main types peracetic acid (most
commonly used), glutaraldehyde (10 hours contact time), formaldehyde (24 hours
contact time) ,and heat disinfection (with citric acid) (20 hours contact time).
Peracetic acid is more expensive than most other germicides, but it poses less of a risk
to those using the germicide than do formaldehyde or glutaraldehyde
