Step-by-step explanation:
The nurse should identify hypotension (C) as the priority finding to report to the provider when caring for a client with a methicillin-resistant Staphylococcus aureus (MRSA) infection receiving vancomycin via IV infusion. Hypotension can be a sign of a severe infection or sepsis, which requires immediate medical attention. Nausea (A), back pain (B), and chills (D) are common side effects of vancomycin infusion and may not require immediate medical attention.
