What is a necessary step before administering medication to a resident?

Verifying the medication against the MAR (Medication Administration Record) is crucial before administering any medication to a resident. The MAR serves as a detailed log that includes information about the prescribed medications, dosages, administration times, and routes. By cross-checking the medication against the MAR, you ensure that you are giving the right drug in the correct dosage to the intended resident at the appropriate time. This process helps to prevent medication errors, which can have serious consequences for the resident's health and safety.

Confirming dietary restrictions, consulting with the resident about their preferences, and checking budget considerations, while important in their respective contexts, do not directly relate to the immediate safety and accuracy of medication administration. These steps do not ensure that the medication being given is correct according to what has been prescribed, which is the primary concern before administering medication.
