ATI Pathophysiology Exam
1. A patient is receiving epoetin alfa (Epogen) for anemia. Which of the following adjunctive therapies is imperative with epoetin alfa?
- A. Potassium supplements
- B. Sodium restriction
- C. Iron supplement
- D. Renal dialysis
Correct answer: C
Rationale: The correct answer is C: Iron supplement. When a patient is receiving epoetin alfa for anemia, it is imperative to provide iron supplementation as epoetin alfa works by stimulating the production of red blood cells, which require iron for hemoglobin synthesis. Therefore, iron supplementation is crucial to support the increased erythropoiesis. Choices A, B, and D are incorrect because potassium supplements, sodium restriction, and renal dialysis are not typically indicated as adjunctive therapies with epoetin alfa for anemia.
2. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What is a key contraindication that the nurse should review with the patient?
- A. History of hypertension
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of peptic ulcer disease
Correct answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both act as vasodilators, and their combined use can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because having a history of hypertension, using antihypertensive medications, or having a history of peptic ulcer disease are not key contraindications for sildenafil use.
3. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strangely and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:
- A. Alzheimer's disease.
- B. vascular dementia.
- C. dementia with Lewy bodies.
- D. frontotemporal dementia.
Correct answer: C
Rationale: The correct answer is dementia with Lewy bodies (DLB). Hallucinations, parkinsonian symptoms (like bradykinesia and limb rigidity), and fluctuating cognition are characteristic of DLB. Alzheimer's disease (Choice A) typically presents with memory loss as a prominent feature. Vascular dementia (Choice B) is associated with a history of strokes and step-wise cognitive decline. Frontotemporal dementia (Choice D) often presents with changes in behavior and personality rather than the parkinsonian symptoms seen in this case.
4. A patient is starting on alendronate (Fosamax) for osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
- B. Take the medication at bedtime to ensure absorption during sleep.
- C. Take the medication with milk to enhance calcium absorption.
- D. Take the medication with food to prevent gastrointestinal upset.
Correct answer: A
Rationale: The correct answer is to take alendronate with a full glass of water and remain upright for at least 30 minutes. This is essential to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because taking alendronate at bedtime can increase the risk of esophageal irritation due to lying down. Choice C is incorrect as taking alendronate with milk can reduce its absorption. Choice D is incorrect because alendronate should be taken on an empty stomach to enhance its effectiveness.
5. Why is testosterone therapy prescribed for a 70-year-old man being treated for osteoporosis?
- A. To increase bone density
- B. To reduce the risk of fractures
- C. To enhance sexual performance
- D. To restore testosterone levels
Correct answer: D
Rationale: The primary reason for prescribing testosterone therapy for osteoporosis in men is to restore testosterone levels, not specifically to increase bone density. Testosterone plays a crucial role in maintaining bone density, so by restoring testosterone levels, it indirectly helps in maintaining bone density. Choices A and B are partially correct but do not address the primary reason for testosterone therapy in this context. Choice C is incorrect as the main focus of testosterone therapy in osteoporosis treatment is not related to enhancing sexual performance.
