Final answer:
The recommended intervention for a patient at risk for fluid volume deficit is to increase fluid intake. Monitoring fluid output is also important.
Step-by-step explanation:
The intervention recommended for a patient at risk for fluid volume deficit is a) Increase fluid intake. This helps to prevent dehydration and restore fluid balance in the body. When a person is at risk for fluid volume deficit, they can increase their fluid intake by drinking water or consuming foods and beverages that are high in water content, such as fruits and vegetables.
Monitoring fluid output is also important to assess the patient's hydration status. This can be done by measuring urine output, body weight, and vital signs. If the patient is unable to consume enough fluids orally, intravenous fluid therapy may be necessary, but this should be determined by a healthcare professional based on the patient's specific needs and condition.
