Correct Answer: A

Rationale: Raloxifene decreases bone resorption, which helps to maintain or increase bone density, making it effective in the prevention and treatment of osteoporosis.

Correct Answer: C

Rationale: The correct answer is C: Bronchospasm. Zanamivir (Relenza) is an inhaled medication used to treat influenza by reducing the severity and duration of symptoms. Patients with a history of asthma are at risk of bronchospasm as a potential side effect of zanamivir. Assessing for bronchospasm is crucial in this case to ensure the patient's safety and well-being. Choices A, B, and D are incorrect. Bradycardia, pneumonia, and pulmonary embolism are not commonly associated with zanamivir use in the treatment of influenza B, especially in a patient with a history of asthma.

Correct Answer: A

Rationale: Medroxyprogesterone acetate (Provera) is commonly used to treat conditions like abnormal uterine bleeding, amenorrhea, and endometriosis. It helps regulate the menstrual cycle and reduce excessive bleeding. Therefore, the correct answer is A. Choice B, cervical cancer, is incorrect because Provera is not indicated for the treatment of cancer. Choice C, ovarian cancer, is also incorrect as Provera is not a primary treatment for ovarian cancer. Choice D, fibromyalgia, is unrelated to the use of medroxyprogesterone acetate.

Correct Answer: B

Rationale: The correct answer is B. HIV is a retrovirus that infects T cells and leads to the gradual destruction of the immune system. Choice A is incorrect because HIV infects T cells primarily, not just B cells. Choice C is incorrect because HIV infection requires host cell receptors for entry. Choice D is incorrect because cell death after HIV infection is not immediate; instead, the virus gradually weakens the immune system over time.

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.
