Final answer:
A. Petechiae The nurse should expect to find a friction rub when caring for a client with pericarditis, which is an inflammation of the pericardium.
Step-by-step explanation:
A nurse caring for a client with pericarditis should expect to find a friction rub as a clinical finding. Pericarditis, which is the inflammation of the sac surrounding the heart, often presents with chest pain, difficulty breathing, and a dry cough. Its diagnosis can involve a variety of tests such as chest radiographs, electrocardiograms, echocardiograms, and perhaps the collection of pericardial fluid for analysis. A friction rub, which is the sound made by the rubbing of the pericardial layers against each other, is typically heard when auscultating the heart with a stethoscope and is indicative of pericarditis.
