Ethinyl estradiol and drospirenone (Yaz).

Finasteride.

Desogestrel (Mirena).

Medroxyprogesterone acetate (Depo-Provera).

Answer and Explanation

Correct Answer : A,C,D

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.

Correct Answer is A

Explanation

Choice A rationale

Ondansetron (Zofran) is an anti-emetic medication used to prevent nausea and vomiting by blocking serotonin receptors in the chemoreceptor trigger zone and the gastrointestinal tract.

Choice B rationale

Acetaminophen (Tylenol) is an analgesic and antipyretic medication used to relieve pain and reduce fever, but it is not an anti-emetic.

Choice C rationale

Prochlorperazine (Compazine) is an anti-psychotic and anti-emetic medication used to treat nausea and vomiting, as well as certain mental/mood disorders.

Choice D rationale

Morphine Sulfate is an opioid analgesic used to relieve moderate to severe pain but does not have anti-emetic properties.

A. Medication routes that are affected by the first-pass effect include intravenous, intramuscular, and intradermal. B. Enteric-coated tablets and capsules are affected by the first-pass effect except a pharmacologic effect. C. The first-pass effect is when the liver activates all medications on their first pass through the liver. D. Enteral medications may need a higher dose due to the first-pass effect.

Correct Answer is D

Explanation

Choice A rationale

Intravenous, intramuscular, and intradermal routes bypass the first-pass effect as they do not pass through the liver first.

Choice B rationale

Enteric-coated tablets and capsules are designed to bypass the stomach and dissolve in the intestines, reducing the first-pass effect.

Choice C rationale

The first-pass effect involves the liver metabolizing and inactivating a portion of the medication on its first pass through the liver.

Choice D rationale

Enteral medications, which pass through the digestive system, may require higher doses due to the first-pass effect where the liver metabolizes the medication before it reaches systemic circulation. .
