ATI Pathophysiology Final Exam

1. Medroxyprogesterone acetate (Provera) is indicated for the treatment of women with

Correct answer: A

Rationale: Medroxyprogesterone acetate (Provera) is commonly used to treat conditions like abnormal uterine bleeding, amenorrhea, and endometriosis. It helps regulate the menstrual cycle and reduce excessive bleeding. Therefore, the correct answer is A. Choice B, cervical cancer, is incorrect because Provera is not indicated for the treatment of cancer. Choice C, ovarian cancer, is also incorrect as Provera is not a primary treatment for ovarian cancer. Choice D, fibromyalgia, is unrelated to the use of medroxyprogesterone acetate.

2. What causes atherosclerotic plaques to form initially?

Correct answer: B

Rationale: Atherosclerotic plaques form initially due to injury to the coronary artery endothelium, which triggers a cascade of events leading to plaque buildup. Choice A is incorrect because atherosclerotic plaques do not form due to an interruption of blood flow to the brain. Choice C is incorrect as statin medications are actually used to help lower cholesterol and reduce the risk of plaque formation. Choice D is incorrect as poor dietary modifications can contribute to atherosclerosis but are not the initial cause of plaque formation.

3. A client presents to the emergency department with lower right quadrant abdominal pain, fever, nausea, and occasional diarrhea. After palpating the abdomen, the client displays tenderness. What would the nurse anticipate the client to be experiencing?

Correct answer: C

Rationale: The correct answer is C: Appendicitis. The symptoms described - lower right quadrant abdominal pain, fever, nausea, diarrhea, and tenderness upon palpation - are classic signs of appendicitis. Appendicitis is an inflammatory condition of the appendix that often presents with these symptoms and requires immediate medical attention. Choice A, Pseudomembranous colitis, typically presents with watery diarrhea and is associated with antibiotic use. Choice B, Peptic ulcer disease, commonly presents with epigastric pain related to meals and can be accompanied by nausea or vomiting, but it does not typically cause right lower quadrant pain. Choice D, Esophageal cancer, usually presents with symptoms related to swallowing difficulties, weight loss, and sometimes chest pain, but it is not associated with the symptoms described in the scenario.

4. A 5-year-old female takes a hike through the woods during a school field trip. Upon returning home, she hugs her father, and he later develops poison ivy. Which of the following immune reactions is he experiencing?

Correct answer: D

Rationale: The father's immune reaction to poison ivy is an example of cell-mediated immunity, specifically a type IV hypersensitivity reaction. In this type of reaction, sensitized T cells react to antigens, leading to inflammation and tissue damage. IgE-mediated reactions involve antibodies of the IgE class, commonly seen in allergic responses like anaphylaxis. Tissue-specific reactions target specific organs or tissues. Immune complex reactions involve immune complexes formed by antigens and antibodies that can deposit in tissues, leading to inflammation.

5. What is the etiology and most likely treatment for myasthenia gravis in a 22-year-old female college student?

Correct answer: B

Rationale: Myasthenia gravis is characterized by a decline in functioning acetylcholine receptors rather than autoimmune destruction of skeletal muscle cells (Choice A), cerebellar lesions (Choice C), or excess acetylcholinesterase production (Choice D). The most likely treatment for myasthenia gravis involves corticosteroids to reduce inflammation and intravenous immunoglobulins to block the antibodies attacking acetylcholine receptors. Intensive physical therapy and anabolic steroids are not primary treatments for myasthenia gravis.
