If a client has a cough, what should be done before thoracentesis?

Administering a cough suppressant before thoracentesis is a crucial step to help minimize the risk of complications during the procedure. A cough can interfere with the careful positioning needed to safely access the pleural space, particularly when the client is required to remain as still as possible. Reducing the cough reflex helps to ensure that the client can cooperate during the process, thus allowing the healthcare provider to perform the procedure more effectively and with less likelihood of causing trauma to surrounding tissues.

While deep breathing exercises are beneficial for improving lung expansion and oxygenation, they do not address the immediate concern of a cough potentially disrupting the procedure. Delaying the procedure until the cough resolves may not be practical, as it could lead to further complications, such as worsening pleural effusion. Administering antibiotics is typically not indicated beforehand for thoracentesis unless there is a known infection that requires treatment; the primary focus should be on managing the cough reflex to ensure the procedure can be completed safely and effectively.
