1. Which of the following is the most likely indication for the use of immunosuppressant agents?
- A. Intractable seizure disorders
- B. Increased intracranial pressure
- C. Organ transplantation
- D. HIV/AIDS with multiple drug resistance
Correct answer: C
Rationale: The correct answer is C: Organ transplantation. Immunosuppressant agents are commonly used in organ transplant recipients to prevent organ rejection by suppressing the immune system. Choices A, B, and D are incorrect. Intractable seizure disorders are often managed with antiepileptic drugs, increased intracranial pressure is managed through various means like surgery and medications, and HIV/AIDS with multiple drug resistance is typically treated with antiretroviral therapy, not immunosuppressant agents.
2. 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.
3. A client with chronic obstructive pulmonary disease (COPD) is admitted to the hospital for pneumonia. Which intervention should the nurse prioritize?
- A. Administer bronchodilators as prescribed.
- B. Monitor oxygen saturation levels continuously.
- C. Administer intravenous antibiotics as prescribed.
- D. Provide respiratory therapy treatments as needed.
Correct answer: C
Rationale: Administering IV antibiotics is crucial for treating pneumonia in a client with COPD. Pneumonia is an infection of the lungs that requires prompt antibiotic therapy to prevent complications and improve outcomes. While bronchodilators may help with COPD symptoms, in the case of pneumonia, addressing the infection is the priority. Continuous monitoring of oxygen saturation is important, but administering antibiotics to treat the underlying infection takes precedence. Respiratory therapy treatments can be beneficial, but they are not the initial priority when managing pneumonia in a client with COPD.
4. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). What should the nurse include in the patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism.
- B. Tamoxifen may decrease the risk of osteoporosis.
- C. Tamoxifen may cause hot flashes and other menopausal symptoms.
- D. Tamoxifen may cause weight gain and fluid retention.
Correct answer: A
Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about signs and symptoms of blood clots, such as swelling, pain, or redness in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and menopausal symptoms, or causing weight gain and fluid retention.
5. 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.
