ATI Pathophysiology Exam 2
1. A client on an acute medicine unit of a hospital with a diagnosis of small bowel obstruction is reporting intense, diffuse pain in her abdomen. Which physiologic phenomenon is most likely contributing to her complaint?
- A. Somatic pain resulting from pressure on the parietal peritoneum
- B. Referred pain from her small bowel
- C. Visceral pain resulting from distension and ischemia
- D. Neuropathic pain resulting from autonomic dysfunction
Correct answer: C
Rationale: Visceral pain is associated with distension, ischemia, and inflammation of internal organs. In the case of a small bowel obstruction, the intense, diffuse pain reported by the client is likely due to the distension and ischemia of the small bowel. Somatic pain (Choice A) would be more localized and sharp, typically arising from the parietal peritoneum. Referred pain (Choice B) is pain perceived at a site distant from the actual pathology. Neuropathic pain (Choice D) involves dysfunction or damage to the nervous system and is not typically associated with the described physiologic phenomenon of distension and ischemia in the context of a small bowel obstruction.
2. A patient is taking medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse teach the patient about this medication?
- A. Medroxyprogesterone should be taken with food to prevent nausea.
- B. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
- C. Medroxyprogesterone can be taken intermittently when symptoms worsen.
- D. Medroxyprogesterone should be stopped if side effects occur.
Correct answer: B
Rationale: The correct answer is B. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Choice A is incorrect because medroxyprogesterone does not necessarily need to be taken with food. Choice C is incorrect as it is typically prescribed continuously rather than intermittently. Choice D is incorrect because patients should not stop the medication if side effects occur without consulting their healthcare provider.
3. Which of the following describes the etiology of a cerebrovascular accident (CVA)?
- A. A blow to the head from a hard object
- B. Lack of blood flow to part of the brain
- C. Excessive exercise, such as running
- D. A ruptured artery in the heart
Correct answer: B
Rationale: The correct answer is B. A cerebrovascular accident (CVA), or stroke, is often caused by a lack of blood flow to part of the brain. This leads to damage in the brain tissue due to the deprived oxygen and nutrients. Choices A, C, and D are incorrect. A blow to the head from a hard object can cause a traumatic brain injury but is not the etiology of a CVA. Excessive exercise like running does not typically lead to a stroke. A ruptured artery in the heart may result in a heart attack, not a cerebrovascular accident.
4. The early stages of atheroma development are characterized by:
- A. macrophages full of oxidized low-density lipoprotein (LDL; i.e., foam cells) in the intima
- B. accumulation of lipids in the intima (i.e., fatty streak)
- C. accumulation of proteins such as collagen and elastin (i.e., fibrous cap)
- D. development of calcium and a necrotic lipid core
Correct answer: A
Rationale: The correct answer is A. In the early stages of atheroma development, macrophages accumulate oxidized low-density lipoprotein (LDL) and transform into foam cells, leading to the formation of fatty streaks in the intima of blood vessels. This process is a hallmark of the initial stages of atherosclerosis. Choice B is incorrect as it describes the accumulation of lipids in the intima, which is a later event following foam cell formation. Choice C is also incorrect as it refers to the accumulation of proteins forming the fibrous cap, which occurs at a later stage to stabilize the atheroma. Choice D is incorrect as it describes the development of calcium and a necrotic lipid core, typically seen in advanced atherosclerosis rather than the early stages.
5. Which of the following statements characterizes irritable bowel syndrome?
- A. Typically does not cause anemia
- B. Not generally associated with intestinal E. coli
- C. Can be associated with anxiety and/or depression
- D. Not often associated with bloody diarrhea
Correct answer: C
Rationale: Irritable bowel syndrome (IBS) is a gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits. While IBS can lead to symptoms like diarrhea or constipation, it typically does not cause anemia (choice A), is not generally associated with intestinal E. coli (choice B), and is not often associated with bloody diarrhea (choice D). However, IBS can indeed be associated with anxiety and/or depression (choice C) due to the gut-brain axis, a bidirectional communication system between the gut and the brain. This association is well-documented in IBS patients, highlighting the importance of considering psychological factors in managing the condition.
