What should the nurse discuss with a patient with a history of cardiovascular disease regarding the risks of hormone replacement therapy (HRT)?
- A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may improve mood and energy levels.
- D. HRT may decrease the risk of breast cancer.
Correct Answer: A
Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT is not typically used to decrease the risk of osteoporosis. Choice C is incorrect as mood and energy level improvements are not the primary risks associated with HRT. Choice D is incorrect because HRT may actually increase the risk of breast cancer in some individuals.

- B. HRT may improve mood and energy levels, but it also increases the risk of osteoporosis.
- C. HRT can decrease the risk of fractures, but it also increases the risk of developing diabetes.
- D. HRT may increase the risk of breast cancer, so regular mammograms are essential.

A group of prison inmates developed tuberculosis following exposure to an infected inmate. On examination, tissues were soft and granular (like clumped cheese). Which of the following is the most likely cause?
- A. Coagulative necrosis
- B. Liquefactive necrosis
- C. Caseous necrosis
- D. Autonecrosis
Correct Answer: C
Rationale: The correct answer is C. Caseous necrosis is characteristic of tuberculosis, where the tissue has a soft, cheese-like appearance. Coagulative necrosis involves protein denaturation, liquefactive necrosis is seen in brain infarcts and abscesses, and autonecrosis is not a recognized term in pathology, making them incorrect choices in this scenario.
A patient with breast cancer is prescribed tamoxifen (Nolvadex). What important information should the nurse provide during patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
- B. Tamoxifen may cause weight gain, so patients should monitor their diet.
- C. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.
- D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.
Correct Answer: A
Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism, a serious side effect, so patients should be educated about the signs and symptoms of blood clots. This information is crucial as early recognition and prompt treatment of blood clots can prevent complications. Choices B, C, and D are incorrect because tamoxifen is not associated with causing weight gain, decreasing the risk of osteoporosis, or increasing the risk of breast cancer. Providing accurate information is essential for patient safety and understanding.
A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary mechanism of action for this medication?

- B. Raloxifene increases calcium absorption in the intestines, which helps build stronger bones.
- C. Raloxifene stimulates new bone formation by increasing osteoblast activity.
- D. Raloxifene decreases calcium excretion by the kidneys, helping to maintain bone density.
