When providing medications from floor stock to a patient on the Alzheimer's unit of a long-term care facility, the nurse demonstrates the principle of drug administration by performing which of the following?

A. Checking the label before taking the medication out of the cabinet, pouring the medication, and placing the bottle back in the cabinet. This option does not follow the "three checks" principle effectively. The label should also be checked after pouring and before administering the medication to ensure accuracy. B. Checking the label while removing the bottle from the cabinet, after pouring the dose of medication, and while replacing the bottle in the cabinet. This option correctly follows the "three checks" principle: when removing the medication from the cabinet, after pouring the dose, and when replacing the bottle. This ensures that the right medication is given in the correct dose. C. Checking the label after removing the bottle from the cabinet and pouring the dose of medication and before closing the cabinet door. This option misses the second check before administering the medication, which is essential to ensure the correct drug and dosage. D. Checking the label before leaving the medication room. Checking the label before leaving the medication room does not ensure that the correct medication and dosage are being administered at the bedside.
