A nurse is reinforcing teaching with the parents of a 13-month-old child following administration of the measles, mumps, and rubella (MMR) immunization. Which of the following statements by the nurse is appropriate?

A. Celecoxib is contraindicated in individuals with a history of hypersensitivity reactions, including anaphylaxis, angioedema, or urticaria, to sulfonamides. Sulfonamide antibiotics are structurally related to sulfonamide nonantibiotics, including celecoxib, and cross-sensitivity reactions may occur in some individuals.
B. Penicillin allergy is not a contraindication for celecoxib. There is no cross-reactivity between penicillin antibiotics and celecoxib, as they are different classes of medications.
C. Concurrent use of chondroitin is not a contraindication for celecoxib. Chondroitin is a dietary supplement commonly used for joint health, and there are no known interactions or contraindications between chondroitin and celecoxib.
D. Concurrent use of calcium supplements is not a contraindication for celecoxib. There are no known interactions between calcium supplements and celecoxib, and they can be safely used together if indicated.

A. Checking the prescription in the client's medical record can help confirm the correct medication and dosage prescribed by the healthcare provider. It allows the nurse to verify the intended medication and compare it with what was supplied by the pharmacy.
B. While asking the client about allergies is important for medication safety, it may not directly address the discrepancy between the listed medication (phenobarbital) and the supplied medication (pentobarbital). Allergies are relevant to ensuring the safety of the medication administration, but they may not provide immediate clarification of the discrepancy.
C. This action may provide some context about the client's medication history, but it does not directly address the discrepancy between the listed medication and the supplied medication. The focus should be on confirming the correct medication for administration according to the client's current prescription.
D. This action may provide information about the client's previous medication administration history, but it does not directly address the discrepancy between the listed medication and the supplied medication. The nurse's primary concern should be to verify the correct medication to be administered at the current time.
