A staff nurse is working with a client on the medical unit.
The health care provider prescribes aspirin for the client to treat headache.
The client forgets and drinks two bottles of beer, which caused GI bleeding.
How should the nurse analyze this drug-drug interaction?

Antagonistic reaction.

Synergistic reaction.

Additive reaction.

Neutral reaction.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Antagonistic reactions occur when one drug interferes with the action of another, decreasing its effectiveness. This is not applicable in this case as aspirin and alcohol together increase the risk of bleeding rather than opposing each other's actions.

Choice B rationale

Synergistic reactions happen when two drugs enhance each other's effects. Aspirin and alcohol together can indeed increase the risk of gastrointestinal bleeding, but this is not referred to as a synergistic reaction.

Choice C rationale

Additive reactions occur when two drugs with similar effects add up to a greater effect. Aspirin and alcohol both increase the risk of bleeding, and their combined effect leads to gastrointestinal bleeding.

Choice D rationale

Neutral reactions imply that the drugs do not interact and have no combined effect, which is incorrect here as the combination of aspirin and alcohol leads to an increased risk of GI bleeding.

Correct Answer is A

Explanation

Choice A rationale

Vitamin K1 is used as an antidote for warfarin toxicity because it helps in the synthesis of clotting factors, reversing the anticoagulant effects of warfarin.

Choice B rationale

Protamine sulfate is used to counteract the effects of heparin, not warfarin.

Choice C rationale

Heparin is an anticoagulant and would worsen bleeding if given in the case of warfarin toxicity.

Choice D rationale

Digibind is used to treat digoxin toxicity and has no role in reversing the effects of warfarin. .

A. Ethinyl estradiol and drospirenone (Yaz). B. Finasteride. C. Desogestrel (Mirena). D. Medroxyprogesterone acetate (Depo-Provera).

Correct Answer is ["A","C","D"]

Explanation

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.
