Correct Answer is B

Explanation

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.

A. Determining which medication needs a prescription for the patient to obtain. B. Ensuring the patient taking a medication has an option for generic medications. C. Providing specific requirements for the manufacture of generic medications. D. Indicating which medications are controlled substances and enforcing the laws.

Correct Answer is D

Explanation

A. Determining which medication needs a prescription for the patient to obtain. The DEA does not determine which medications require prescriptions; this is typically under the jurisdiction of the Food and Drug Administration (FDA).

B. Ensuring the patient taking a medication has an option for generic medications. This role is more aligned with the FDA, which oversees the approval of generic medications. The DEA does not handle generic medication options.

C. Providing specific requirements for the manufacture of generic medications. This is also a role of the FDA, not the DEA. The DEA focuses on controlled substances, not the specifics of generic drug manufacturing.

D. Indicating which medications are controlled substances and enforcing the laws. This accurately describes the role of the DEA. The DEA classifies controlled substances into schedules and enforces the laws related to the handling, prescribing, and dispensing of these drugs.
