The symptom described by the term xerostomia is which of the following?

• A. Dry mouth
• B. Itchy eyes
• C. Dizziness
• D. Nausea

Answer: (A)

Xerostomia is the dry mouth that results from reduced saliva production. This directly describes dryness in the oral cavity, which is why it’s the correct choice. The other options—itchy eyes, dizziness, and nausea—are unrelated to saliva and do not define this term. In cancer care, xerostomia can occur with head-and-neck radiation or certain chemotherapies, and it can make eating, swallowing, speaking, and tasting difficult while increasing the risk of dental decay. Management focuses on keeping the mouth moist and comfortable: frequent sips of water, saliva substitutes or stimulants, good oral hygiene, fluoride use, avoiding irritants like tobacco and alcohol, and using a humidifier; more persistent cases should be discussed with the care team for potential saliva-stimulating therapies or therapy adjustments.
