Question 1 of 5
A nurse is caring for a client who has a serum potassium level of 5.5 mEq/L. The provider prescribes polystyrene sulfonate. If this medication is effective, the nurse should expect which of the following changes on the client's ECG?
Correct Answer: C
Rationale: This is correct because a reduction of T-wave amplitude is a sign of hyperkalemia reversal. Polystyrene sulfonate lowers serum potassium, reversing ECG changes like peaked T waves.
