Question 1 of 5

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?

Correct Answer: C

Rationale: Polystyrene sulfonate reduces serum potassium levels. Hyperkalemia causes peaked T waves on an ECG, so effective treatment would result in a reduction of this abnormality.

A nurse is caring for a client who has developed a thrombus and is receiving heparin by continuous IV infusion. The client asks the nurse how long will it take for the heparin to dissolve the clot. Which of the following responses should the nurse give?

Correct Answer: A

Rationale: Heparin prevents further clot formation by enhancing antithrombin activity but does not dissolve existing clots; thrombolytics are needed for that.
