A nurse is reinforcing teaching with a client who is scheduled for a thoracentesis. Which of the following information should the nurse include in the teaching?

Thoracentesis is a procedure performed to remove fluid or air from the pleural space to improve breathing and obtain diagnostic samples. Proper positioning is essential to allow optimal access to the pleural cavity while minimizing risk of lung injury. Nursing teaching focuses on patient positioning, procedural expectations, and safety measures. Understanding what to expect helps reduce anxiety and improve cooperation during the procedure. Rationale: A. Lying on the affected side after thoracentesis is not a standard requirement. Post-procedure care typically involves monitoring for complications such as pneumothorax and assessing respiratory status. The position described is not used as a routine post-procedure intervention. B. Moderate sedation is not routinely administered for thoracentesis. The procedure is usually performed under local anesthesia to numb the insertion site while the patient remains awake and able to follow instructions. Sedation may increase risk by suppressing respiratory drive and is not standard practice. C. Leaning over a bedside table (often called the Fowler’s or tripod position) is the correct positioning for thoracentesis. This position spreads the intercostal spaces, improves access to the pleural fluid, and reduces the risk of lung injury. It also promotes patient comfort and optimal procedural visualization. D. Being NPO (nothing by mouth) for four hours is not required for thoracentesis. Since general anesthesia or deep sedation is not typically used, fasting is unnecessary. Patients are usually allowed to eat and drink prior to the procedure unless otherwise specified by provider orders.
