VERSION!!
Explain the four transport mechanisms that play a role in
hemodialysis .......ANSWER......● Ultrafiltration: Fluid is pushed
through a semipermeable membrane.
● Convection: Or solute drag means that solutes move with the
water across the semipermeable membrane. In this way,
convection adds to the clearance achieved through diffusion as
solutes are dragged along with the ultrafiltrate.
● Diffusion: Is the movement of dissolved particles across a
semipermeable membrane from the side with the higher
concentration to the side with the lower concentration. This
,Page 2 of 64
difference in solute concentration on each side of the membrane
is called concentration gradient. The higher the concentration
gradient, the faster diffusion occurs. Once the concentration of a
dissolved particle is the same on both sides of the
semipermeable membrane, diffusion stops.
● Osmosis: Is a chemical process by which dissolved chemicals
will migrate from an area of high concentration to one of low
concentration. Essentially if you dissolve something in a liquid, the
dissolved compounds (called solutes) will spread out until there is
an equal concentration of solute everywhere.
What are the kidneys excretory functions .......ANSWER......To
normalize electrolytes, remove wastes, provide fluid and nutrient
balance
,Page 3 of 64
What is the function of the acid concentration
.......ANSWER......Provides the concentration gradient for diffusion
and helps normalize electrolytes
What is the function of bicarbonate .......ANSWER......Buffers the
acid concentrate
Signs and symptoms of hyperkalemia .......ANSWER......> 5.5
mEq: extreme muscle weakness, abnormal heart rhythm, possible
cardiac arrest
Signs and symptoms of hypokalemia .......ANSWER......< 3.5 mEq:
fatigue, muscle weakness, paralysis, respiratory failure, cardiac
instability, arrhythmias, cardiac arrest
What are the kidneys endocrine functions .......ANSWER......Renin
secretion, Erythropoeitin secretion, Vit D Activation
, Page 4 of 64
How do we replace normal endocrine kidney functions
.......ANSWER......Provide medications
How much of normal kidney function is replaced by hemodialysis
.......ANSWER......15%
What is uremia and how does it affect the body?
.......ANSWER......Uremia is a buildup of wastes in the blood due
to kidney failure and affects all body systems.
What are the most common causes of CKD in the usa?
.......ANSWER......Diabetes
Hypertension
Polycystic Kidney Disease
Outline the treatment goals for a patient with CKD
.......ANSWER......-slowing the progression of ckd
-managing comorbidities and complications
-controlling symptoms
