Practice Question

A nurse is caring for a client who has a serum potassium level of 5.9 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?

Answer Choices:

A. Prolonged PR intervals

B. Widening QRS Complex

C. A reduction of a peaked T wave ✓ Correct Answer

D. An increase in T wave amplitude

Correct Answer:

A reduction of a peaked T wave

Rationale:

✔A peaked T wave is a hallmark ECG finding in hyperkalemia. Polystyrene sulfonate (Kayexalate) treats hyperkalemia by facilitating potassium excretion via the gastrointestinal tract.

🧨When effective, the ECG will show normalization of the T wave as potassium levels decrease.

👉Widened QRS and prolonged PR intervals may also occur in severe hyperkalemia, but reduction of peaked T waves is the best marker of treatment efficacy.
