A client receiving IV potassium supplementation complains of burning at the insertion site. What is the nurse's priority action?
Rationale: Burning at an IV site can signal infiltration or phlebitis. The safest first step is to stop the infusion and assess the site.
Which finding in a patient with heart failure most urgently requires the nurse to notify the provider?
Rationale: Bilateral crackles with severe dyspnea suggest acute pulmonary edema, a life-threatening complication of heart failure.
A patient is prescribed metoprolol. Which teaching point is most important?
Rationale: Abruptly stopping a beta-blocker can cause rebound hypertension, tachycardia, and angina. Taper only under provider direction.
