What nursing action should be prioritized for a patient experiencing mucositis due to chemotherapy?

Prioritizing oral care for a patient experiencing mucositis due to chemotherapy is essential because mucositis can lead to significant discomfort and complications such as infections and difficulties with swallowing and eating. Proper oral hygiene helps to maintain the integrity of the oral mucosa, reduce the risk of oral infections, and alleviate pain associated with mucositis.

Effective oral care may include using gentle mouth rinses, applying soothing agents, and avoiding irritants that could exacerbate the condition. By focusing on oral care, the nurse can help manage symptoms more effectively and improve the patient's overall comfort and quality of life during treatment.

Other options, while valuable in specific contexts, do not directly address the immediate needs associated with mucositis. Increasing activity, administering sedatives, or encouraging high-fiber foods may be appropriate in different clinical scenarios, but they do not specifically target the discomfort and complications arising from mucositis, making oral care the priority action in this case.
