While preparing to administer a scheduled IV medication, the client tells the nurse that the IV site hurts and refuses to allow the nurse to administer a flush to assess the site. Which intervention should the nurse implement?

A. Applying ice and then a warm compress may provide some comfort, but it does not address the underlying issue of potential IV site complications. B. Redressing the IV site while assessing for redness may be useful, but if the client is experiencing pain and refusal of care, a more decisive action is warranted. C. Discontinuing the IV site after inserting a new access is the most appropriate intervention when there are concerns about the IV site, especially if the client reports pain. D. Reviewing the medical record for the date of insertion can provide context but does not address the immediate concern regarding the client's discomfort.
