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 B

Explanation

Choice A rationale

This statement is incorrect because an antagonist medication changes the effects of normal cellular functions by blocking receptors.

Choice B rationale

An antagonist medication binds to receptors and blocks the usual receptor activity, preventing the normal action of the endogenous substance.

Choice C rationale

This statement describes an agonist medication, which binds to receptors and increases the effects of normal cellular functions.

Choice D rationale

This statement is incorrect because an antagonist medication does not both increase and decrease the effects on normal cellular functions; it primarily blocks receptor activity.

A. Benztropine. B. Protamine sulfate. C. Vitamin K. D. Digibind.

Correct Answer is B

Explanation

Choice A rationale

Benztropine is an anticholinergic agent used to treat Parkinsonism and extrapyramidal symptoms, not suitable for reversing heparin effects.

Choice B rationale

Protamine sulfate is the specific antidote for heparin overdose. It works by neutralizing the anticoagulant effects of heparin.

Choice C rationale

Vitamin K is an antidote for warfarin overdose, promoting the synthesis of clotting factors, but ineffective against heparin.

Choice D rationale

Digibind is an antidote for digoxin toxicity, not appropriate for counteracting heparin.
