A nurse is caring for a client who is newly diagnosed with Parkinson's disease.
Which of the following medications should the nurse anticipate to administer to the client?

Choice A rationale

Controlled substances have a potential for dependence because they can cause physical and psychological dependence when misused. The dependence is characterized by withdrawal symptoms when the substance is not used, and it is a key factor in the regulation of these substances.

Choice D rationale

Controlled substances have a Schedule classification as mandated by the Controlled Substances Act (CSA). The schedule classification indicates the potential for abuse and medical use, with Schedule I substances having the highest potential for abuse and no accepted medical use, while Schedule V substances have the lowest potential for abuse.

Choice A rationale

Ethinyl estradiol and drospirenone (Yaz) is a combination oral contraceptive used to prevent pregnancy. It works by inhibiting ovulation, altering the cervical mucus to prevent sperm penetration, and changing the uterine lining to prevent implantation.

Choice B rationale

Finasteride is not used for contraception or prevention of pregnancy. It is primarily used to treat benign prostatic hyperplasia (BPH) and androgenetic alopecia (male pattern baldness).

Choice C rationale

Desogestrel (Mirena) is a hormonal intrauterine device (IUD) used for long-term contraception. It releases a progestin hormone that thickens cervical mucus, inhibits sperm motility, and thins the endometrial lining to prevent pregnancy.

Choice D rationale

Medroxyprogesterone acetate (Depo-Provera) is an injectable contraceptive that provides long-term prevention of pregnancy. It prevents ovulation and thickens cervical mucus to inhibit sperm penetration.
