Question 1

What is the primary function of hemodialysis?

Accepted Answer

To remove waste products and excess fluid from the blood

Answer

Hemodialysis filters the blood to remove uremic waste products, excess electrolytes, and fluid that damaged kidneys can no longer eliminate.

Question 2

Which vascular access site is considered the 'gold standard' for long-term hemodialysis?

Accepted Answer

Arteriovenous fistula

Answer

An arteriovenous (AV) fistula is preferred because it has the lowest complication rates, longest patency, and best outcomes for long-term dialysis patients.

Question 3

What does the dialysate solution used in hemodialysis typically contain?

Accepted Answer

Electrolytes such as sodium, potassium, calcium, and bicarbonate

Answer

Dialysate is a purified water solution containing electrolytes at physiologic concentrations to facilitate diffusion of waste products out of the blood.

Question 4

What is the typical duration of a standard hemodialysis treatment session?

Accepted Answer

3–5 hours

Answer

Most in-center hemodialysis sessions last 3–5 hours (commonly 4 hours), performed three times per week to achieve adequate solute clearance.

Question 5

Which complication is most commonly observed during hemodialysis treatments?

Accepted Answer

Intradialytic hypotension

Answer

Intradialytic hypotension (IDH) is the most common complication, occurring due to rapid fluid removal, vasodilation, or cardiac dysfunction during treatment.
