The client is diagnosed with pericarditis. When assessing the client, the nurse is unable to auscultate a friction rub. Which action should the nurse implement?
Correct Answer: C
Rationale: The correct action for the nurse to implement when unable to auscultate a pericardial friction rub in a client diagnosed with pericarditis is to ask the client to lean forward and listen again. Leaning forward can help bring the heart closer to the chest wall, making it easier to detect the rub. Option A (Notifying the healthcare provider) is incorrect because further assessment is needed before escalating the situation. Option B (Documenting that the pericarditis has resolved) is incorrect as the absence of a friction rub does not necessarily mean resolution. Option D (Preparing to insert a unilateral chest tube) is incorrect as this intervention is not indicated for the absence of a friction rub.
