ATI Pathophysiology Exam 1 Questions

Question 1 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.

Question 2 of 5

What condition can be caused by an excessive amount of growth hormone released by the pituitary gland in childhood?

Correct Answer: B

Rationale: Gigantism is the correct answer. It is a condition caused by excessive growth hormone release before the epiphyseal plates close, leading to abnormal growth. Acromegaly (choice A) is caused by excess growth hormone after the epiphyseal plates close, resulting in enlargement of bones and tissues. Syndrome of inappropriate antidiuretic hormone (choice C) is characterized by the excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia. Dwarfism (choice D) is a condition characterized by significantly below-average height.

Question 3 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 4 of 5

Which of the following hormones helps to raise the blood sugar level to help maintain homeostasis?

Correct Answer: C

Rationale: The correct answer is C, Glucagon. Glucagon helps raise blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, thus aiding in maintaining homeostasis. Antidiuretic hormone (ADH), choice A, functions in regulating water balance in the body, not blood sugar levels. Insulin, choice B, lowers blood sugar levels by facilitating glucose uptake by cells. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism and has no direct effect on blood sugar levels.

Question 5 of 5

What causes hepatic encephalopathy?

Correct Answer: B

Rationale: Hepatic encephalopathy is caused by increased ammonia levels in the bloodstream. Ammonia, a byproduct of protein metabolism normally processed by the liver, accumulates in the bloodstream when the liver is unable to function properly. This excess ammonia affects brain function, leading to symptoms of hepatic encephalopathy. Choices A, C, and D are incorrect because they do not directly relate to the pathophysiology of hepatic encephalopathy.
