producing calcitriol
-Symptoms that a patient may need more dialysis time include: - -Anorexia,
fatigue, swelling

certain sized particles to cross
-Diffusion is movement of particles: - -From an area of higher concentration
-Negative pressure is pressure created when: - -Fluid is pulled through a
restriction
-During dialysis, ultrafiltration occurs when: - -Water is removed from blood
because there is a pressure gradient between blood and dialysate

negative pressure? - -The arterial line section before the blood pump

across the semipermeable membrane? - -High concentration gradients

-________ is the normal range for a resting pulse rate in an adult: - -60-100
beats/min.
