In response to Mr. Clinton's increasing pain and nausea, what assessment should the nurse perform first?

In this scenario, the priority assessment that the nurse should perform first is to reassess the wound site. Understanding the correlation between the patient's symptoms, specifically the increasing pain and nausea, and the condition of their wound is crucial. Wound-related complications such as infection or worsening of the underlying issue can manifest as pain and nausea.

By reassessing the wound site, the nurse can gather vital information that may help determine the cause of the patient's discomfort. This includes checking for signs of infection, drainage, or any changes in the appearance of the wound. Identifying these issues promptly can facilitate timely and appropriate interventions, which is essential in managing the patient's overall condition effectively.

The other choices, while they may be relevant steps in a management plan, do not address the immediate need to understand the underlying factors contributing to Mr. Clinton's symptoms. Providing distractions can help alleviate discomfort, but it does not address the root cause of the pain. Administering pain medication might offer short-term relief but may mask symptoms without addressing potential complications. Contacting the provider for an anxiolytic could be an appropriate action depending on the situation, but like the previous options, it does not prioritize an assessment that could reveal critical information about the patient’s current condition.
