A nurse has received bedside report on a group of clients. Which client is at the greatest risk for developing oral abnormalities?

A. A client who reports difficulty chewing solid foods may have existing oral problems, such as dental issues or temporomandibular joint discomfort, but this alone does not indicate an ongoing risk for developing new oral abnormalities unless underlying causes are present. B. A client who brushes their teeth twice daily demonstrates good oral hygiene, which reduces the risk of oral abnormalities such as caries, gingivitis, or oral infections. This client is least at risk. C. A client with a history of seasonal allergies may occasionally experience mild oral irritation, dry mouth, or inflammation due to mouth breathing, but this is generally temporary and low risk for chronic oral abnormalities. D. A client with a history of vaping three times a week is at the greatest risk for oral abnormalities. Vaping exposes oral tissues to chemicals that can cause dry mouth, inflammation, mucosal irritation, periodontal disease, and increased risk of oral infections. Repeated exposure can compromise the integrity of the oral mucosa and increase susceptibility to cavities, gum disease, and other oral pathologies.
