ATI Pathophysiology Final Exam Questions
Question 1 of 5
A patient with a history of osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic effect of this medication?
Correct Answer: B
Rationale: The correct answer is B. Raloxifene, such as Evista, works by decreasing bone resorption and increasing bone density. This medication is beneficial in the prevention and treatment of osteoporosis by slowing down the breakdown of bone tissue, thereby reducing the risk of fractures. Choices A, C, and D are incorrect because raloxifene does not directly stimulate the formation of new bone, increase calcium absorption in the intestines, or increase the excretion of calcium through the kidneys.
Question 2 of 5
What should the nurse discuss with a patient with a history of cardiovascular disease regarding the risks of hormone replacement therapy (HRT)?
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.
Question 3 of 5
A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What condition would contraindicate the use of this medication?
Correct Answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients using nitrates due to the risk of severe hypotension. Nitrates and tadalafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of hypertension, the use of antihypertensive medications, and a history of peptic ulcer disease are not direct contraindications for tadalafil use.
Question 4 of 5
A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary mechanism of action for this medication?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A patient with breast cancer is prescribed tamoxifen (Nolvadex). What important information should the nurse provide during patient education?
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.
