Final answer:
To increase a cancer patient's nutritional intake, the nurse should provide frequent, small meals, encourage high-calorie, high-fat foods, and administer antiemetic medication.
Step-by-step explanation:
In order to increase the nutritional intake of a cancer patient experiencing anorexia, it is important to implement the following interventions:
Provide frequent, small meals: Offering smaller portions of meals throughout the day can help to increase the patient's appetite and make eating more manageable.
Encourage high-calorie, high-fat foods: These types of foods can provide a higher calorie intake and help the patient maintain their weight or gain weight during treatment.
Administer antiemetic medication: Nausea and vomiting can be common side effects of cancer treatment. Administering antiemetic medication can help to alleviate these symptoms, making it easier for the patient to eat.
