Final answer:
The care plan for an infant with Deficient fluid volume should include oral electrolyte replacement solutions, breast milk, or lactose-free formula, and if needed, I.V. fluid replacement therapy.
Step-by-step explanation:
Appropriate Intervention for Fluid Volume Deficiency in Infants
The care plan for a 6-month-old infant with a nursing diagnosis of Deficient fluid volume related to excessive GI losses in stool and emesis should include the following intervention: Oral electrolyte replacement solutions, breast milk, or lactose-free formula. This approach is supported by medical recommendations that suggest the use of oral rehydration solutions, which consist of water, salts, and sugar, to manage dehydration, particularly caused by conditions such as gastroenteritis. For severe cases, I.V. fluid replacement therapy may be required. However, it's crucial to start with oral electrolyte solutions early to prevent severe dehydration and maintain the child's health. For older children, the BRAT diet might be recommended when reintroducing food, but for infants, it is more important to continue breast milk or formula. The infant's ability to tolerate these fluids and the degree of dehydration will dictate whether I.V. therapy is necessary.
