Which of the following is an important intervention when administering NSAIDs?

Administering nonsteroidal anti-inflammatory drugs (NSAIDs) with food or milk is an important intervention because these medications can irritate the gastric mucosa, leading to gastrointestinal discomfort or potentially more serious complications like ulcers or bleeding. Taking NSAIDs with food or milk can help to buffer the stomach lining and reduce the risk of these adverse effects, making it a critical practice for patient safety and comfort.

Additionally, while monitoring vital signs and considering age-related risks are certainly part of patient care, they are not specific interventions associated directly with the administration of NSAIDs in the same way that food or milk is. Using NSAIDs with caution in the elderly is essential, but it is a broader consideration of dosage and overall health, rather than a specific intervention related to administration.
