Electrolytes

Question 1

Polystyrene sulfonate resins

Answer 1

For potassium imbalance

Sodium or calcium ions of the resin are exchanged for potassium ions (and other cations) in the GIT; the resin is then excreted thus reducing potassium levels.

Question 2

Aluminium hydroxide

Answer 2

Phosphate binder

Bind dietary phosphate in the GIT forming a poorly absorbed compound; absorption of phosphate is reduced thus decreasing serum phosphate concentration.

Question 3

Calcium carbonate

Answer 3

Phosphate binder

Bind dietary phosphate in the GIT forming a poorly absorbed compound; absorption of phosphate is reduced thus decreasing serum phosphate concentration.

Question 4

Lanthanum

Answer 4

Phosphate binder

Bind dietary phosphate in the GIT forming a poorly absorbed compound; absorption of phosphate is reduced thus decreasing serum phosphate concentration.

Question 5

Sevelamer

Answer 5

Phosphate binder

Bind dietary phosphate in the GIT forming a poorly absorbed compound; absorption of phosphate is reduced thus decreasing serum phosphate concentration.

Question 6

Sucroferric oxyhydroxide

Answer 6

Phosphate binder

Bind dietary phosphate in the GIT forming a poorly absorbed compound; absorption of phosphate is reduced thus decreasing serum phosphate concentration.
