A nurse is teaching a client who is to begin taking tamoxifen to treat breast cancer. The nurse should instruct the client to expect which of the following findings as an adverse effect of the medication?

Choice A reason: A 32-year-old client who has benign breast disease does not have a contraindication for receiving oral contraceptives. Benign breast disease is not associated with an increased risk of breast cancer or thromboembolic events. However, the nurse should advise the client to perform regular breast self-examinations and report any changes.

Choice B reason: A 26-year-old client who has migraine headaches at the start of each menstrual cycle does not have a contraindication for receiving oral contraceptives. Migraine headaches that are related to the menstrual cycle may actually improve with oral contraceptives, as they can regulate the hormonal fluctuations. However, the nurse should monitor the client for any signs of stroke or hypertension, as these are rare but serious complications of oral contraceptives.

Choice C reason: A 28-year-old client who has a history of pelvic inflammatory disease does not have a contraindication for receiving oral contraceptives. Pelvic inflammatory disease is an infection of the reproductive organs that can cause infertility, chronic pain, and ectopic pregnancy. Oral contraceptives can reduce the risk of pelvic inflammatory disease by creating a thick cervical mucus that prevents the entry of bacteria. However, the nurse should remind the client that oral contraceptives do not protect against sexually transmitted infections, and that barrier methods should be used in addition.

Choice D reason: A 38-year-old client who reports smoking one pack of cigarettes every day has a contraindication for receiving oral contraceptives. Smoking increases the risk of cardiovascular diseases, such as myocardial infarction, stroke, and peripheral vascular disease. Oral contraceptives also increase the risk of these diseases, especially in women older than 35 years. Therefore, the combination of smoking and oral contraceptives can have a synergistic effect and cause serious harm. The nurse should recommend other methods of contraception for this client, such as intrauterine devices, implants, or injections.

Choice A reason: This is incorrect because alendronate is not safe during pregnancy, as it may harm the fetus or cause birth defects. The client should inform the provider if they are pregnant or planning to become pregnant before taking this medication.

Choice B reason: This is incorrect because the client should not lie down for at least 30 minutes after taking alendronate, as this may cause esophageal irritation, ulceration, or bleeding. The client should take alendronate with a full glass of water and swallow it whole, without chewing or crushing.

Choice C reason: This is incorrect because the client should not continue smoking while on alendronate, as smoking can worsen the bone loss and increase the risk of fractures. The client should quit smoking or reduce the amount of cigarettes they smoke.

Choice D reason: This is correct because the client should avoid alcohol with alendronate, as alcohol can also worsen the bone loss and increase the risk of fractures. Alcohol can also interact with alendronate and cause side effects, such as stomach upset, drowsiness, or liver damage.

Choice E reason: This is correct because the client should sit up for at least 30 minutes after taking alendronate, as this can prevent the medication from refluxing back into the esophagus and causing irritation, ulceration, or bleeding. The client should also avoid eating or drinking anything other than water for at least 30 minutes after taking alendronate, as this can reduce its absorption and effectiveness.
