A client with a history of emphysema and heart failure is admitted to the emergency department with enema, coughing, and shortness of breath. The client's laboratory value for brain natriuretic peptide is elevated. Which prescription is most important for the nurse to implement?

Choice A reason: Administering IV furosemide (a diuretic) is crucial for managing the client's symptoms of fluid overload, as indicated by enema and elevated brain natriuretic peptide (BNP) levels. Furosemide helps reduce the volume of fluid in the body, relieving symptoms of heart failure and improving breathing. It addresses the most urgent need for the client.Choice B reason: Inserting an indwelling urinary catheter might be necessary for accurate measurement of urine output, especially in a client receiving diuretic therapy. However, it is not the most immediate intervention needed to stabilize the client's condition.Choice C reason: Monitoring for telemetry ST segment changes is important for clients with cardiac conditions. While it is necessary for ongoing assessment, it does not address the immediate need to relieve fluid overload and improve the client's respiratory status.Choice D reason: Giving a bronchodilator per inhaler can help with respiratory symptoms related to emphysema. However, in this scenario, the primary issue is fluid overload due to heart failure, which needs to be addressed first with diuretic therapy.
