DaVita (RN) Final Exam/Actual Questions and AnswersLatest 2024/2025/100% Correct.
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 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
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

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 important to know what caused your patients
CKD - ANSWER-So the nurse and PCT can inquire
about possible problems during data collection and
assessment
Why is sodium balance important? - ANSWER-Leads to
volume expansion, increased cardiac output, increased
peripheral vascular resistance, and increased blood
pressure
Signs and symptoms of fluid imbalance - ANSWER-
Edema, hypertension, shortness of breath
Systemic effects of CKD what would you advise for a
patient who complains of: dry itchy skin, peripheral
neuropathy(nerve pain in extremities) and gi problems -
ANSWER-Use hyper-fatted soaps and lotions, monitor
patient for changes in motor function and inform RN and
physician of any bleeding problems/constipation/diarrhea
What is the consequences of prolonged fluid overload and
hypertension - ANSWER-Left ventricular hypertrophy
What is Percarditis? - ANSWER-Inflammation of the
membrane (pericardial sac) around the heart
