ATI RN Custom Exams Set 1
1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:
- A. Platelets
- B. Vitamin K
- C. Calcium
- D. Vitamin B12
Correct answer: B
Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.
2. Which of the following is a primary intervention for managing hyperphosphatemia?
- A. Increasing calcium intake
- B. Increasing phosphorus intake
- C. Decreasing calcium intake
- D. Administering phosphate binders
Correct answer: D
Rationale: The correct answer is D, administering phosphate binders. Phosphate binders are a primary intervention for managing hyperphosphatemia as they help by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (choice A) or phosphorus intake (choice B) would exacerbate hyperphosphatemia. Decreasing calcium intake (choice C) is not a primary intervention for managing high phosphorus levels.
3. In assessing the client's chest, which position best shows chest expansion as well as its movements?
- A. Sitting
- B. Prone
- C. Sidelying
- D. Supine
Correct answer: A
Rationale: The position that best shows chest expansion as well as its movements is when the client is sitting. When the client is seated, their chest is in an optimal position for observing the full range of chest expansion during breathing. This position allows for easy visualization of chest movements and expansion as the client breathes in and out, providing a comprehensive assessment of respiratory function. Choice B (Prone) and Choice D (Supine) involve positions where the chest's movements and expansion are less visible and may not provide an accurate representation of respiratory function. Choice C (Sidelying) can also limit the visibility of chest expansion compared to the sitting position.
4. Who is the first individual in the combat health support chain to make medically substantiated decisions based on military occupational specialty-specific medical training?
- A. Physician
- B. Physician assistant
- C. Combat medic
- D. Combat lifesaver
Correct answer: B
Rationale: The correct answer is 'Physician assistant.' Physician assistants are trained to make medically substantiated decisions based on their specific medical training within the combat health support chain. Choice A, 'Physician,' is incorrect as they may be involved but are not typically the first in line for such decisions as physician assistants. Choice C, 'Combat medic,' is incorrect as they usually provide immediate medical care but may not be the first to make medically substantiated decisions. Choice D, 'Combat lifesaver,' is incorrect as they are trained to provide basic life-saving interventions but may not have the specialized medical training to make complex medical decisions.
5. When assessing a client for an endocrine dysfunction, which question should the nurse ask?
- A. “Have you noticed any pain in your legs when walking?”
- B. “Have you had any unexplained weight loss?”
- C. “Have you noticed any change in your bowel movements?”
- D. “Have you experienced any joint pain or discomfort?”
Correct answer: B
Rationale: The correct answer is B: “Have you had any unexplained weight loss?” Unexplained weight loss can be a common symptom of various endocrine disorders, such as hyperthyroidism and diabetes. This weight loss is often despite an adequate or increased appetite. Choices A, C, and D are less likely to be directly associated with endocrine dysfunction. Pain in the legs when walking could be related to musculoskeletal issues, changes in bowel movements may suggest gastrointestinal concerns, and joint pain is more commonly linked to rheumatologic conditions rather than primary endocrine disorders.
