A nurse is caring for a client who is taking tamoxifen to treat breast cancer. The nurse should identify which of the following manifestations as an adverse effect of this medication?
Tinnitus.
Hot flashes.
Urinary frequency.
Constipation.
The Correct Answer is B
Hot flashes are a common side effect of tamoxifen, which is hormone therapy for breast cancer that blocks the action of estrogen.
Tamoxifen can cause menopause-like symptoms in women, such as irregular or missing periods, vaginal discharge or bleeding, and mood changes. Choice A is wrong because tinnitus (ringing in the ears) is not a known side effect of tamoxifen.
Choice C is wrong because urinary frequency (needing to urinate more often) is not a known side effect of tamoxifen.
Choice D is wrong because constipation (difficulty passing stools) is not a known side effect of tamoxifen.

Correct Answer is B
Explanation
Carbamazepine is an anticonvulsant medication that is used to treat seizures and nerve pain. It works by reducing the activity of certain nerve cells in the brain.
Choice A is wrong because beclomethasone is a corticosteroid that is used to treat asthma and allergic rhinitis. It does not interact with carbamazepine.
Choice B is correct because the estrogen-progestin combination is a hormonal contraceptive that is used to prevent pregnancy and regulate menstrual cycles. It interacts with carbamazepine because carbamazepine can increase the breakdown of estrogen and progestin in the body, making them less effective. The nurse should instruct the client to use an alternative or additional method of birth control while taking carbamazepine.
Choice C is wrong because diphenhydramine is an antihistamine that is used to treat allergies, motion sickness, and insomnia. It does not interact with carbamazepine.
Choice D is wrong because the nicotine transdermal system is a nicotine replacement therapy that is used to help people quit smoking. It does not interact with carbamazepine.
Correct Answer is D
Explanation
This is because TB is caused by a bacterium that can develop resistance to single-drug therapy, so a combination of drugs is used to prevent or treat drug-resistant strains. Some of the common drugs used for TB are isoniazid, rifampin, ethambutol, and pyrazinamide.
Choice A is wrong because the duration of treatment for active TB is usually 6 to 9 months, not 3 years.
Choice B is wrong because tuberculin skin tests are not reliable indicators of disease activity or response to treatment, as they can remain positive for years after successful therapy.
Choice C is wrong because blood tests to monitor kidney function are not routinely required for TB treatment unless the client has a preexisting renal impairment or is taking drugs that are nephrotoxic.
