How can you differentiate pleural friction rub from pleuritic chest pain on exam and what is the nursing approach to assessment and patient comfort?

• A. Friction rub is a coarse rubbing sound heard during inspiration only; pleuritic pain is unaffected.
• B. Friction rub is inaudible; pleuritic pain is heard as a rubbing sound.
• C. Friction rub is a coarse rubbing sound heard on auscultation with respiration; pleuritic pain worsens with inspiration or movement; approach includes assessing chest pain, auscultating, treating underlying pleuritis/infection, and providing analgesia and pacing education.
• D. Friction rub is a wheeze; pleuritic pain is constant.

Answer: (C)

The key idea is that you distinguish a pleural friction rub by its audible sound during breathing, and you separate that from the symptom of pleuritic chest pain, which is the pain itself that worsens with inspiration or movement. A friction rub shows up as a coarse, scratching, grating sound heard with auscultation as the patient breathes; it is produced by inflamed pleural surfaces sliding against each other and is not a wheeze or an inaudible finding. Pleuritic pain, meanwhile, is typically sharp or stabbing and loca­lized, and it becomes more intense with deep inspiration or chest wall movement, which guides the nursing plan to focus on pain control and encouraging slower, deeper breaths.

In practice, assess by taking a careful history of the chest pain and performing focused lung auscultation during respiration to detect the friction rub, distinguishing it from other sounds. Address the underlying cause (such as pleuritis from infection, pneumonia, or other inflammatory processes) and provide comfort measures. This includes administering analgesia as ordered, teaching pacing and energy-conservation strategies, and using techniques that promote breathing without excessive pain, like splinting and incentive spirometry when appropriate. Monitor vital signs and respiratory status, and be prepared to adjust care if pain worsens or if signs of complications arise.
