Answer and Explanation

The Correct Answer is D

A. Placebo group: A placebo group refers to participants receiving an inactive substance or placebo, not the research design itself.

B. Experimental drug: The term "experimental drug" refers to the drug being tested, not the design of the study.

C. Control group: The control group receives the placebo or standard treatment for comparison, but this term does not describe the study design.

Correct Answer is A

Explanation

A. Therapeutic level: This is the correct answer. It refers to the concentration of a drug in the bloodstream at which it achieves the desired effect without causing toxicity.

B. Therapeutic index: This is a ratio that compares the toxic dose to the therapeutic dose of a drug. It does not refer to the point of optimal effect.

C. Toxic level: This refers to the concentration of a drug at which it becomes harmful or toxic. It is not associated with the desired effect.

D. Therapeutic range: This refers to the range between the minimum effective concentration and the toxic concentration of a drug. It does not pinpoint the optimal effect but indicates the safe range.

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.
