Final Exam Pathophysiology
1. What is the etiology and most likely treatment for myasthenia gravis in a 22-year-old female college student?
- A. Autoimmune destruction of skeletal muscle cells; treatment with intensive physical therapy and anabolic steroids.
- B. A decline in functioning acetylcholine receptors; treatment with corticosteroids and intravenous immunoglobulins.
- C. Cerebellar lesions; surgical and immunosuppressive treatment.
- D. Excess acetylcholinesterase production; treatment with thymectomy.
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.
2. A client with a history of deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which complication should the nurse monitor for?
- A. Pulmonary embolism
- B. Gastrointestinal bleeding
- C. Hemorrhagic stroke
- D. Renal insufficiency
Correct answer: A
Rationale: The correct answer is A, pulmonary embolism. In a client with a history of deep vein thrombosis (DVT) receiving anticoagulant therapy, the nurse should monitor for pulmonary embolism, as it is a serious complication. Pulmonary embolism occurs when a blood clot dislodges from the veins and travels to the lungs, potentially causing life-threatening consequences. Choices B, gastrointestinal bleeding, C, hemorrhagic stroke, and D, renal insufficiency, are not directly associated with deep vein thrombosis or anticoagulant therapy. While these complications may occur in other situations, they are not the primary concern when managing a client with a history of DVT.
3. When the maternal immune system becomes sensitized against antigens expressed by the fetus, what type of immune reaction occurs?
- A. Autoimmune
- B. Anaphylaxis
- C. Alloimmune
- D. Allergic
Correct answer: C
Rationale: When the maternal immune system becomes sensitized against antigens expressed by the fetus, an alloimmune reaction occurs. In this situation, the mother's immune system recognizes the fetus as foreign due to differences in antigens, leading to an immune response against the fetus. Choice A, 'Autoimmune,' is incorrect because it refers to the immune system mistakenly attacking the body's own cells and tissues. Choice B, 'Anaphylaxis,' is not the correct answer as it is a severe allergic reaction that can be life-threatening. Choice D, 'Allergic,' is also incorrect as it refers to an immune response triggered by allergens, not antigens expressed by the fetus.
4. A patient has been prescribed clomiphene citrate (Clomid) for infertility. What should the nurse include in the teaching plan about the use of this medication?
- A. Clomiphene is taken daily for 5 days at the beginning of the menstrual cycle.
- B. Clomiphene is taken once daily throughout the menstrual cycle.
- C. Clomiphene is taken twice daily for 5 days at the end of the menstrual cycle.
- D. Clomiphene is taken three times daily for 10 days at the beginning of the menstrual cycle.
Correct answer: A
Rationale: Corrected Rationale: Clomiphene is typically taken daily for 5 days at the beginning of the menstrual cycle to stimulate ovulation. Choice A is the correct answer because it aligns with the standard dosing regimen for clomiphene citrate. Choices B, C, and D provide incorrect information about the dosing schedule for clomiphene, which can lead to ineffective treatment and potential side effects. Choice B suggests continuous daily intake, which is not the standard practice for clomiphene. Choice C and D mention different dosing frequencies and timings, which are not in line with the typical protocol for using clomiphene for infertility.
5. Which term should the nurse use to document a situation in which cells increase in size and function?
- A. Atrophy
- B. Hypertrophy
- C. Metaplasia
- D. Hyperplasia
Correct answer: B
Rationale: Hypertrophy is the correct term used to describe the situation in which cells increase in size and function. Atrophy (Choice A) is the opposite, indicating a decrease in cell size. Metaplasia (Choice C) refers to the reversible replacement of one mature cell type by another. Hyperplasia (Choice D) involves an increase in the number of cells, not just an increase in size and function as in hypertrophy.
