For a client at 29 weeks of gestation with phenylketonuria, which food is most appropriate?

For a client with phenylketonuria (PKU) at 29 weeks of gestation, the most appropriate food choice is the sliced apple and red grapes.

Phenylketonuria is a metabolic disorder that results in an inability to metabolize phenylalanine, an amino acid found in high-protein foods. Because individuals with PKU must carefully manage their intake of phenylalanine to prevent toxic levels that can lead to severe neurological damage, their diet is typically low in protein.

The sliced apple and red grapes are low in protein and do not contain significant amounts of phenylalanine, making them a safe and healthy snack option for this client. Fruits such as apples and grapes provide essential vitamins and minerals while being safe for someone with PKU.

In contrast, the peanut butter sandwich, chocolate chip cookie with milk, and scrambled egg with cheddar cheese are all higher in protein and therefore contain significant amounts of phenylalanine, which would not be appropriate for someone managing PKU. These higher protein foods could jeopardize the client's health by increasing phenylalanine levels, making them unsuitable choices.
