Pathophysiology Exam 1 Quizlet Questions
Question 1 of 5
A male patient with erectile dysfunction is prescribed sildenafil (Viagra). What specific instruction should the nurse provide to ensure the safe use of this medication?
Correct Answer: B
Rationale: The correct instruction the nurse should provide is to avoid taking nitrates while on sildenafil (Viagra). Combining sildenafil with nitrates can result in severe hypotension due to additive vasodilatory effects. Choice A is incorrect because sildenafil can be taken with or without food. Choice C is incorrect as there is no specific requirement to take sildenafil at bedtime. Choice D is incorrect as taking sildenafil with milk has not been shown to enhance its absorption.
Question 2 of 5
What is the primary action of bisphosphonates when prescribed to a patient with osteoporosis?
Correct Answer: A
Rationale: The correct answer is A: "It inhibits bone resorption, which helps maintain bone density." Bisphosphonates work by inhibiting bone resorption carried out by osteoclasts, thereby preventing the breakdown of bones and helping to maintain or increase bone density in patients with osteoporosis. Choices B, C, and D are incorrect because bisphosphonates do not directly stimulate new bone formation, increase calcium absorption in the intestines, or decrease calcium excretion by the kidneys.
Question 3 of 5
A patient with a history of breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse include in the patient education?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What specific instructions should the nurse provide to ensure the effectiveness of the medication?
Correct Answer: A
Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. This positioning helps reduce the risk of esophageal irritation and ensures adequate drug absorption. Choice B is incorrect because alendronate should be taken with water, not milk. Choice C is incorrect as there is no specific advantage to taking alendronate at bedtime. Choice D is incorrect because taking alendronate with food may interfere with its absorption.
Question 5 of 5
A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?
Correct Answer: A
Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.
