Which monitoring is recommended during IV potassium therapy?

• A. Assess peripheral sites at least hourly
• B. Assess once daily
• C. Do not monitor unless symptoms appear
• D. Only monitor if infusion is at the maximum rate

Answer: (A)

IV potassium therapy can irritate veins and, if infiltrated, cause tissue injury, while rapid shifts in potassium levels can affect heart rhythm. Because problems can develop quickly, frequent monitoring of the IV site and infusion rate is essential. Assessing peripheral sites at least hourly allows you to detect infiltration, phlebitis, or extravasation early and stop or adjust the infusion before damage occurs. It also ensures the potassium is infusing at the prescribed rate and concentration, reducing the risk of complications. Waiting for symptoms or checking only rarely misses early warning signs, which is why hourly site checks are preferred.
