ATI Pathophysiology Final Exam Questions
Question 1 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 2 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?

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 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 4 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.
Question 5 of 5
Which of the following is a characteristic of the human immunodeficiency virus (HIV), which causes AIDS?
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.
