Why are antianxiety medications used cautiously in older adults?

Choice A rationale
Neither heparin nor warfarin work to dissolve clots that have already formed. Instead, they work by reducing the blood’s ability to clot, preventing the formation of new clots and the growth of existing ones.
Choice B rationale

While it’s important for healthcare providers to communicate and explain treatments, it’s not necessary for the charge nurse to call the provider for an explanation in this case. The nurse should be able to explain the rationale for the medication regimen.
Choice C rationale
Heparin does not enhance the effects of warfarin. Both are anticoagulants, but they work in different ways and do not enhance each other’s effects.
Choice D rationale
Heparin will be continued until the warfarin reaches a therapeutic level. Heparin and warfarin are both anticoagulants that decrease the clotting ability of the blood and help prevent harmful clots from forming in the blood vessels. However, they work in different ways to achieve therapeutic coagulation and must be given together until therapeutic levels of anticoagulation can be achieved by warfarin alone, which usually takes about 3 days.

Choice A rationale

Misoprostol (Cytotec) is contraindicated in pregnant women because it can induce labor or cause miscarriages. It is sometimes used in obstetrics to induce labor or to treat postpartum hemorrhage, but it should never be used in pregnant women to treat peptic ulcers.
Choice B rationale
There is no contraindication for using misoprostol in a client who has osteoarthritis.
Choice C rationale
Misoprostol does not interact with medications typically used to treat urinary tract infections, and there is no contraindication for its use in these clients.
Choice D rationale
Misoprostol does not interact with medications typically used to treat kidney stones, and there is no contraindication for its use in these clients.
