Final answer:
Sodium polystyrene is used in medicine to treat high potassium levels by binding to potassium in the intestines and preventing its absorption into the bloodstream.
Step-by-step explanation:
Sodium polystyrene is a type of polymer that is used in medicine to treat high levels of potassium in the blood. It works by binding to potassium in the intestines and preventing its absorption into the bloodstream. This helps to lower potassium levels and prevent complications associated with high potassium, such as irregular heart rhythms.
Sodium polystyrene is often given to patients with kidney problems or certain medical conditions that can cause high potassium levels. It can be taken orally or administered through an enema. The exact dosage and administration method will depend on the individual's specific condition and their healthcare provider's recommendations.
