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 with a diagnosis of renal failure is being treated with epoetin alfa (Epogen). Frequent assessment of which of the following laboratory values should be prioritized before and during treatment?
- A. AST
- B. C-reactive protein
- C. CBC
- D. ALT
Correct answer: A
Rationale: The correct answer is AST. Epoetin alfa is a medication used to treat anemia associated with chronic renal failure. During treatment with epoetin alfa, it is crucial to monitor AST levels as this medication can potentially lead to liver toxicity. Assessing AST levels before and throughout treatment helps in early detection of any liver abnormalities. C-reactive protein is not specifically related to the use of epoetin alfa in renal failure. While CBC (Complete Blood Count) monitoring is essential during treatment with epoetin alfa to evaluate the response to therapy, prioritizing AST assessment is more critical due to the potential for liver toxicity. ALT monitoring is also important but AST is prioritized in this scenario.
3. Canola oil produced from genetically modified canola plants altered to be herbicide-resistant is an example of a:
- A. pesticide-free food.
- B. saturated fat food.
- C. genetically modified food.
- D. product that is pure.
Correct answer: C
Rationale: The correct answer is 'genetically modified food.' Canola oil derived from genetically modified canola plants falls into this category because the plant's genome has been altered to exhibit herbicide resistance. This genetic modification makes it a genetically modified food. Choice A, 'pesticide-free food,' is incorrect as the genetic modification is to resist herbicides, not pesticides. Choice B, 'saturated fat food,' is incorrect as it does not accurately describe the genetic modification of the canola plants. Choice D, 'product that is pure,' is too vague and does not address the genetic modification aspect of the canola plants.
4. The nurse knows which phenomenon listed below is an accurate statement about axonal transport?
- A. Anterograde and retrograde axonal transport allow for the communication of nerve impulses between a neuron and the central nervous system (CNS).
- B. Materials can be transported to the nerve terminal by either fast or slow components.
- C. The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.
- D. Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.
Correct answer: B
Rationale: The correct answer is B. Axonal transport involves the movement of materials to the nerve terminal by either fast or slow components, which is essential for cell survival. Choice A is incorrect because while anterograde and retrograde axonal transport are involved in the movement of materials, they do not specifically relate to the communication of nerve impulses between a neuron and the CNS. Choice C is incorrect because the unidirectional nature of axonal transport does not primarily function to protect the CNS against pathogens. Choice D is incorrect as axonal transport is responsible for the movement of various materials, not just electrical impulses.
5. What assessment is the nurse performing when a client is asked to stand with feet together, eyes open, and hands by the sides, and then asked to close the eyes while the nurse observes for a full minute?
- A. Romberg test
- B. Weber test
- C. Rinne test
- D. Babinski test
Correct answer: A
Rationale: The correct answer is A, Romberg test. The Romberg test is used to assess balance and proprioception. During the test, the client is asked to stand with feet together, eyes open, and hands by the sides to observe their balance. Then, the client is asked to close their eyes while the nurse continues to observe for a full minute. This test helps in detecting any issues with proprioception and balance, which may be compromised in conditions affecting the nervous system. Choices B, C, and D are incorrect because the Weber test is used to assess hearing in each ear, the Rinne test is used to compare air and bone conduction of sound, and the Babinski test is used to assess the integrity of the corticospinal tract.
