ATI Nutrition Practice A
1. All of the following are electrolytes except:
- A. chloride
- B. potassium
- C. sodium
- D. iron
Correct answer: D
Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.
2. A client receiving total parenteral nutrition (TPN is awaiting the next container. What fluid should the nurse infuse in the interim?
- A. Dextrose 5% in water
- B. 0.9% sodium chloride
- C. Dextrose 10% in water
- D. Lactated Ringer's solution
Correct answer: B
Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer's solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.
3. As a nurse, you can help improve the effectiveness of communication among healthcare givers by:
- A. Use of reminders of ‘what to do’
- B. Using standardized list of abbreviations, acronyms, and symbols
- C. One-on-one oral endorsement
- D. Text messaging and e-mail
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
4. A nurse is assessing a client who reports muscle spasms in his calves and tingling in his hands. The client indicates consuming a low intake of milk products and green leafy vegetables. The nurse should identify that the client's findings indicate a deficiency in which of the following sources of nutrition?
- A. Iron
- B. Omega-3 fatty acids
- C. Vitamin C
- D. Calcium
Correct answer: D
Rationale: The correct answer is D, Calcium. Muscle spasms and tingling suggest a calcium deficiency, which is commonly associated with a low intake of milk products and green leafy vegetables. Iron (choice A) deficiency typically presents with fatigue and weakness, not muscle spasms and tingling. Omega-3 fatty acids (choice B) are essential for brain function and heart health, but their deficiency does not manifest as muscle spasms and tingling. Vitamin C (choice C) deficiency leads to scurvy with symptoms like bleeding gums and bruising, not muscle spasms and tingling.
5. Which mineral is important for the synthesis of thyroid hormones?
- A. Iron
- B. Zinc
- C. Iodine
- D. Magnesium
Correct answer: C
Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.
