A patient is taking methadone as part of a heroin withdrawal program. The nurse understands that in this instance methadone is classified as which drug schedule?

C-V

C-II

C-I

C-III

Answer and Explanation

The Correct Answer is B

A. C-V drugs are considered to have the lowest potential for abuse and are typically used for medications like cough preparations with less than 200 milligrams of codeine per 100 milliliters or per 100 grams. Methadone is not classified under C-V.

B. Methadone is classified as a C-II (Schedule II) controlled substance because it has a high potential for abuse, but it also has accepted medical uses, such as for opioid withdrawal management.

C. C-I drugs are considered to have no accepted medical use and a high potential for abuse (e.g., heroin, LSD). Methadone is not classified as a C-I drug.

D. C-III drugs have a moderate potential for abuse and are generally used for medications like anabolic steroids or some barbiturates, but methadone is not classified under C-III.

Correct Answer is A

Explanation

A. The FDA is responsible for regulating and ensuring the safety and efficacy of drugs, medical devices, and other health-related products. All medications must undergo rigorous scientific testing and approval processes overseen by the FDA before they can be marketed to the public.
B. The DEA regulates controlled substances and enforces laws related to drug abuse, but it does not control the scientific testing of medications.
C. The CDC focuses on public health and disease prevention, not the regulation or testing of medications.
D. The Joint Commission accredits healthcare organizations but does not directly oversee the scientific testing of medications.

A. Complete blood counts B. Electrolytes C. Liver enzymes D. Urinalysis

Correct Answer is C

Explanation

a) Complete blood counts (CBC) are useful for monitoring infection, anemia, or bone marrow suppression, but they are not the primary concern for azithromycin and acetaminophen toxicity.

b) Electrolytes are important for general health but are not directly related to the major side effects of these drugs.

c) Liver enzymes (AST, ALT) should be monitored because both azithromycin and acetaminophen can cause hepatotoxicity, especially at high doses. Acetaminophen overdose is a known cause of liver failure.

d) Urinalysis may be helpful in assessing kidney function, but it is not the primary focus when monitoring for drug-induced liver toxicity.
