Understanding Hemodialysis Principles

What is the primary function of hemodialysis?

• To improve digestion

• To replicate kidney functions

• To increase blood pressure

• To enhance muscle growth

Which component of dialysate acts as the solvent?

• Electrolytes

• Glucose

• Urea

• Water

What is the role of a semipermeable membrane in dialysis?

• To allow only large molecules to pass

• To allow all molecules to pass

• To block all molecules

• To allow only small molecules to pass

Which process involves the movement of molecules from high to low concentration?

• Convection

• Filtration

• Diffusion

• Osmosis

What factor does NOT affect the rate of diffusion?

• Color of the solution

• Molecular size

• Concentration gradient

• Temperature

What is ultrafiltration (UF) in the context of dialysis?

• Addition of electrolytes to the blood

• Removal of excess water from blood due to a pressure gradient

• Movement of solutes against a concentration gradient

• Increase in blood glucose levels

What is the purpose of adding sodium to dialysate?

• To enhance protein synthesis

• To decrease blood pressure

• To draw water from other body compartments into the bloodstream

• To increase blood sugar levels

Which process is described as the movement of a solvent from low to high solute concentration?

• Diffusion

• Convection

• Osmosis

• Filtration

What is the role of glucose in dialysate?

• To decrease fluid retention

• To enhance protein absorption

• To increase blood pressure

• To provide energy and help control blood sugar levels

What is the significance of transmembrane pressure (TMP) in dialysis?

• It enhances the taste of the dialysate

• It increases the size of the semipermeable membrane

• It drives ultrafiltration and fluid removal

• It determines the color of the dialysate
