ATI RN
ATI Nutrition Practice Test B 2019
1. Which nutrient is critical for wound healing and immune function?
- A. Vitamin B12
- B. Vitamin C
- C. Vitamin D
- D. Vitamin K
Correct answer: B
Rationale: Vitamin C is essential for collagen formation and immune function.
2. Maintaining a stable internal environment typically requires
- A. positive feedback mechanisms.
- B. an unstable outside environment.
- C. decreased atmospheric pressure.
- D. negative feedback mechanisms.
Correct answer: negative feedback mechanisms.
Rationale: The correct answer is 'negative feedback mechanisms.' In biological systems, negative feedback mechanisms help maintain homeostasis by counteracting any deviations from the set point. They work to stabilize internal conditions and keep them within a narrow range. On the other hand, positive feedback mechanisms amplify changes and are not involved in maintaining stability. Choice B, 'an unstable outside environment,' is incorrect as internal stability is independent of external conditions like weather. Choice C, 'decreased atmospheric pressure,' is also incorrect as it does not directly relate to internal homeostasis.
3. An RN cared for a state senator during the day shift. Later that day he was having dinner with friends when the news mentioned the senator had been hospitalized. The RN�s friends asked if he knew what was wrong with the senator. Which ethical principle should the RN consider when replying?
- A. Fidelity
- B. Confidentiality
- C. Veracity
- D. Accountability
Correct answer: B
Rationale: The principle of confidentiality requires nurses to hold healthcare information and anything patients tell them in the strictest confidence.
4. Which of the following is NOT a part of a process recording?
- A. Non-verbal narrative account
- B. Analysis and interpretation
- C. Audio-visual recording
- D. Verbal narrative account
Correct answer: C
Rationale: A process recording typically includes a non-verbal narrative account (Choice A), an analysis and interpretation (Choice B), and a verbal narrative account (Choice D). These components help in providing a comprehensive assessment of a patient's condition and ensuring that interventions are appropriately targeted for optimized outcomes. An audio-visual recording (Choice C), while it can be a part of some data collection processes, is not typically included in a process recording, making it the correct answer.
5. A client is prescribed prednisone for asthma management. Which statement by the client indicates a need for further teaching?
- A. I will take this medication every day to prevent asthma attacks.
- B. I will avoid people with infections while taking this medication.
- C. I will take this medication with food to prevent stomach upset.
- D. I will stop taking this medication if I feel fine.
Correct answer: D
Rationale: The correct answer is D because prednisone, a corticosteroid, should not be abruptly stopped. It must be tapered off gradually to prevent adrenal insufficiency. Choices A, B, and C demonstrate proper understanding of the medication's use and side effects, emphasizing the importance of daily intake, infection prevention, and taking it with food to avoid stomach upset.
