Final answer:
The nurse should instruct the client to take ibuprofen with food or milk to protect the stomach lining and reduce the risk of gastrointestinal issues.
Step-by-step explanation:
When a client is prescribed ibuprofen, it's important to give proper instructions on how to take this medication to minimize side effects and enhance its effectiveness. Ibuprofen can cause irritation in the stomach lining, so it is generally recommended to take with food or milk to help mitigate this risk. Taking ibuprofen with a full glass of milk or during a meal can help protect the stomach and reduces the likelihood of gastrointestinal upset like indigestion or ulcers.
