What are the 4 transport mechanisms in hemodialysis? - Answer -Ultrafiltration, Convection,
Diffusion,
and Osmosis
What is Ultrafiltration? - Answer -fluid is pushed through semi-permeable membrane
What is Convection? - Answer -fluid drags solutes across the semi-permeable membrane
What is Diffusion? - Answer -particles moving from high to low concentration
What is Osmosis - Answer -fluid is moving from low to high concentration
What are the kidneys excretory functions? - Answer -To normalize electrolytes, remove wastes,
provide
fluid and acid base balance
How do we replace normal excretory kidney functions? - Answer -normalize electrolytes by using
acid
concentrate and provide fluid balance through ultrafiltration
What is the function of the acid concentration? - Answer -creates concentration gradient for
diffusion
and helps normalize electrolytes/
What is the function of bicarbonate in the dialysate solution? - Answer -buffers acid concentration
What is the function of bicarbonate when it diffuses into the patient's blood? - Answer -Normalizes
body
pH
What are the signs and symptoms of hyperkalemia? - Answer -extreme muscle weakness,
abnormal
heart rhythm and poss cardiac arrest
(>5.5 mEq)
What are the signs and symptoms of hypokalemia? - Answer -fatigue, muscle weakness,
respiratory
failure, cardiac instability, arrhythmias, and cardiac arrest
, (<3.5 mEq)
What is normal blood pH range? - Answer -7.35-7.45
What are the kidneys endrocrine functions? - Answer -Renin secretion, erythropoietin, and vitamin
D
activation
How do we replace normal endocrine kidney functions? - Answer -We provide medications
What is Chronic Kidney Disease? - Answer -abnormalities of kidney structure or function present
for
more than 3 months
How much of normal kidney function is replaced by hemodialysis? - Answer -about 15%
What is uremia and how does it affect the body? - Answer -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
-minimizing the effects of ckd on patients' lifestyles
-kidney replacement therapy modality education
-encouraging patients to actively participate in their healthcare
Why is it so important to know what caused your patient's CKD? - Answer -so we can inquire
about
possible problems during data collection and assessment
Signs and symptoms of fluid imbalance - Answer -Hypertension
Edema
Shortness of Breath
Why is sodium balance important? - Answer -Leads to Volume Expansion, increased CO,
increased
