Question 1
What is the primary purpose of hemodialysis?
A) Increase blood sugar levels
B) Remove waste products and excess fluid from the blood
C) Provide nutrition to malnourished patients
D) Administer medications directly into the bloodstream
,,,,answer,,,,: B) Remove waste products and excess fluid from the blood
Rationale: Hemodialysis filters the blood to remove toxins, waste products (urea,
creatinine), and excess fluid in patients with kidney failure.
,Question 2
Which transport mechanism in hemodialysis involves fluid being pushed through a
semipermeable membrane?
A) Diffusion
B) Convection
C) Ultrafiltration
D) Osmosis
,,,,answer,,,,: C) Ultrafiltration
Rationale: Ultrafiltration is the transport mechanism where fluid is pushed through
a semipermeable membrane by hydrostatic pressure. This is how excess fluid is
removed during dialysis.
Question 3
What is convection in the context of hemodialysis?
A) The movement of solutes from high to low concentration
B) Fluid being pushed through a semipermeable membrane
C) Solutes moving with water across the semipermeable membrane (solute drag)
D) The movement of water across a membrane
,,,,answer,,,,: C) Solutes moving with water across the semipermeable
membrane (solute drag)
Rationale: Convection, or solute drag, means that solutes move with the water
across the semipermeable membrane. This adds to the clearance achieved
through diffusion as solutes are dragged along with the ultrafiltrate.
,Question 4
What is the primary mechanism by which waste products are removed during
hemodialysis?
A) Ultrafiltration
B) Convection
C) Diffusion
D) Osmosis
,,,,answer,,,,: C) Diffusion
Rationale: Diffusion is the primary mechanism for waste removal during
hemodialysis. Solutes move from an area of higher concentration (the blood) to an
area of lower concentration (the dialysate) across the semipermeable membrane.
Question 5
Dialysis replaces approximately what percentage of normal kidney function?
A) 5%
B) 15%
C) 50%
D) 85%
,,,,answer,,,,: B) 15%
Rationale: Dialysis replaces only about 15% of normal kidney function. This is why
patients on dialysis still experience many of the effects of kidney failure.
Question 6
What is the excretory function of the kidneys?
, A) Produce red blood cells
B) Activate vitamin D
C) Remove excess water, urea, and metabolic wastes from the blood
D) Regulate blood pressure
,,,,answer,,,,: C) Remove excess water, urea, and metabolic wastes from the
blood
Rationale: The excretory function of the kidneys includes removing excess water,
urea, and metabolic wastes from the blood. Hemodialysis attempts to replicate
this function.
Question 7
What are the endocrine functions of the kidneys?
A) Filtration and reabsorption
B) Renin and erythropoietin secretion, activation of vitamin D
C) Regulation of blood pH only
D) Production of bile
,,,,answer,,,,: B) Renin and erythropoietin secretion, activation of vitamin D
Rationale: The endocrine functions of the kidneys include renin secretion (blood
pressure regulation), erythropoietin secretion (red blood cell production), and
activation of vitamin D (bone health).
Question 8
What is the normal range for adult blood pressure?
