| To reinforce teaching, the technician should remind patients with kidney failure that they should avoid ___________. | smoking |
| How do you assess the adequacy of dialysis? | Through clinical measures and lab tests |
| Compared to the general population, the protein needs of a patient on maintenance hemodialysis are typically: | Higher. |
| In a dialysis machine, the proportioning system does what? | Appropriately mix the dialysate concentrates with water |
