ATI Pathophysiology Exam 1
1. What is the major effect of filgrastim (Neupogen) in a patient with chronic renal failure?
- A. Decreases neutropenia related to chemotherapy
- B. Decreases white blood cells related to infection
- C. Decreases growth of blood vessels due to ischemia
- D. Decreases platelet count related to bleeding
Correct answer: A
Rationale: The major effect of filgrastim (Neupogen) is to stimulate the production of neutrophils, thereby decreasing neutropenia in patients undergoing chemotherapy. This medication helps the bone marrow produce more white blood cells, specifically neutrophils, to reduce the risk of infections associated with low neutrophil counts. Choices B, C, and D are incorrect because filgrastim does not decrease white blood cells related to infection, growth of blood vessels, or platelet count related to bleeding.
2. Macular degeneration occurs as a result of:
- A. loss of lens accommodation
- B. detachment of the retina
- C. increased intraocular pressure
- D. impaired blood supply leading to cellular waste accumulation and ischemia
Correct answer: D
Rationale: Macular degeneration is a condition that affects the macula, a part of the retina responsible for central vision. It is primarily caused by impaired blood supply to the macula, leading to cellular waste accumulation and ischemia. This results in the death of photoreceptor cells and ultimately vision loss. Choices A, B, and C are incorrect because macular degeneration is not related to the loss of lens accommodation, detachment of the retina, or increased intraocular pressure. The correct answer directly addresses the underlying pathophysiology of macular degeneration.
3. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the administration of this medication?
- A. Take the medication at the same time each day to maintain consistent hormone levels.
- B. Discontinue the medication if side effects occur.
- C. Take the medication with food to prevent gastrointestinal upset.
- D. Apply the medication once a week.
Correct answer: A
Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.
4. A client with cystic fibrosis is admitted with a pulmonary exacerbation. Which intervention should the nurse prioritize?
- A. Administer a high-calorie, high-protein diet.
- B. Initiate airway clearance techniques.
- C. Encourage the client to maintain an active lifestyle.
- D. Monitor for signs of respiratory distress.
Correct answer: B
Rationale: During a pulmonary exacerbation in cystic fibrosis, the priority intervention is to initiate airway clearance techniques. These techniques help clear mucus from the airways, improving ventilation and reducing the risk of respiratory complications. Administering a high-calorie, high-protein diet is beneficial for overall nutrition but is not the priority during an exacerbation. Encouraging an active lifestyle is important for long-term health but does not address the immediate need for managing exacerbations. Monitoring for signs of respiratory distress is important, but initiating airway clearance techniques takes precedence in the management of pulmonary exacerbations in cystic fibrosis.
5. A male patient with hypogonadism is receiving testosterone therapy. What is the most serious adverse effect the nurse should monitor for?
- A. Increased risk of breast cancer
- B. Increased risk of cardiovascular events
- C. Increased risk of liver dysfunction
- D. Increased risk of prostate cancer
Correct answer: B
Rationale: The correct answer is B: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events such as heart attacks and strokes, especially in older patients. Monitoring for signs and symptoms of cardiovascular issues is crucial when administering testosterone therapy. Choices A, C, and D are incorrect because testosterone therapy does not typically lead to an increased risk of breast cancer, liver dysfunction, or prostate cancer.
