ATI Pathophysiology Final Exam Questions
Question 1 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 2 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.
Question 3 of 5
A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse emphasize about the risks associated with this therapy?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What important contraindication should the nurse emphasize during patient education?
Correct Answer: A
Rationale: The correct answer is A: 'Use of nitrates.' Sildenafil (Viagra) is contraindicated in patients using nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices B, C, and D are incorrect because they are not direct contraindications for sildenafil use. While a history of hypertension or peptic ulcer disease may require caution, they are not absolute contraindications like the concomitant use of nitrates.
Question 5 of 5
When the body produces antibodies against its own tissue, the condition is called:
Correct Answer: C
Rationale: Autoimmunity is the correct term for a condition where the body's immune system mistakenly targets its own tissues. Alloimmunity (Choice A) refers to an immune response against foreign tissue. Opsonization (Choice B) is a process where pathogens are marked for destruction by immune cells. Hypersensitivity (Choice D) involves an exaggerated immune response against antigens.
