ATI Pathophysiology Exam 1 Questions
Question 1 of 5
A patient has been using Viagra on an intermittent basis for several years. However, he has cited delays in the onset and peak of action as the occasional source of frustration. What PDE5 inhibitor may be of particular benefit to this patient's needs?
Correct Answer: A
Rationale: The correct answer is Avanafil (Stendra). Avanafil has a rapid onset of action compared to other PDE5 inhibitors, making it suitable for patients experiencing delays in onset and peak of action with other medications like Viagra. Tadalafil (Cialis), Vardenafil (Levitra), and Alprostadil (Caverject) do not offer the same rapid onset of action as Avanafil, making them less suitable for addressing the specific needs of this patient.
Question 2 of 5
A 60-year-old male client with a long history of back pain has had little success with a variety of analgesic regimens that his family physician has prescribed. He has recently been diagnosed with a chronic pain disorder. Which teaching points about chronic pain would his physician most likely emphasize to the client?
Correct Answer: A
Rationale: The correct answer is A. Chronic pain is often complex and challenging to treat, necessitating a multimodal approach that may include medication, physical therapy, and behavioral therapy. Choice B is incorrect because chronic pain does not always indicate that an underlying injury has not healed properly; it can persist even after the initial injury has healed. Choice C is incorrect as chronic pain management usually involves a combination of treatments rather than relying solely on a single long-term medication. Choice D is incorrect because chronic pain is not necessarily less severe than acute pain; it can vary in intensity and duration depending on the individual and underlying condition.
Question 3 of 5
A 54-year-old man presents with a temperature of 38.8°C (101.8°F), a racing heart, fatigue, and an upset stomach after spending an afternoon building a deck on a very hot, humid day. The physician assessing the man is performing a differential diagnosis as part of her assessment. Which finding would suggest fever rather than hyperthermia as a cause of the elevation in the man's temperature?
Correct Answer: B
Rationale: Shivering is a physiological response to fever, as the body attempts to generate heat to increase the internal temperature. Hyperthermia, on the other hand, does not involve shivering. Absence of sweating (choice A) is more indicative of hyperthermia, as the body struggles to cool down without sweating. Lack of thirst (choice C) can be seen in both fever and hyperthermia. Increased heart rate (choice D) can occur in both fever and hyperthermia due to the body's attempt to regulate temperature.
Question 4 of 5
A patient with severe peripheral vascular disease has developed signs of dry gangrene on the great toe of one foot. Which of the following pathophysiologic processes most likely contributed to this diagnosis?
Correct Answer: C
Rationale: The correct answer is C: Impaired arterial blood supply. Dry gangrene is typically caused by impaired arterial blood supply, leading to tissue death without bacterial infection. Choices A, B, and D are incorrect. Inappropriate activation of apoptosis is not a common cause of dry gangrene. Bacterial invasion usually leads to wet gangrene, not dry gangrene. Metaplastic cellular changes are not directly associated with the development of dry gangrene.
Question 5 of 5
A 75-year-old male presents with chest pain on exertion. The chest pain is most likely due to hypoxic injury secondary to:
Correct Answer: C
Rationale: The correct answer is C: Ischemia. In this scenario, the 75-year-old male experiences chest pain on exertion, which is indicative of angina. Angina is primarily caused by reduced blood flow to the heart muscle, leading to hypoxic injury. This condition is known as ischemia. Options A, B, and D are incorrect. Malnutrition does not typically cause chest pain related to exertion. Free radicals and chemical toxicity are not common causes of chest pain in the context described. Therefore, the most likely cause of chest pain in this case is ischemia due to reduced blood flow.
