ATI Nutrition Practice Test A 2019
1. Which of the following is reflected in an ECG due to hypokalemia?
- A. Tall T waves and Pathologic Q wave
- B. Widening QRS Complex and U wave
- C. None of the above
- D. Both A and B
Correct answer: B
Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.
2. What level of sodium restriction would be included as part of nutrition therapy for heart failure?
- A. Less than 500 mg per day
- B. 1000 mg to 1500 mg per day
- C. 1500 mg to 3000 mg per day
- D. 3000 to 3500 mg per day
Correct answer: C
Rationale: The correct answer is 1500 mg to 3000 mg per day. This is the level of sodium restriction typically recommended for heart failure patients. It helps manage fluid retention and reduce blood pressure, which are both crucial in treating heart failure. A sodium intake of less than 500 mg per day (Choice A) might be too restrictive and is not typically recommended. Similarly, an intake of 1000 mg to 1500 mg per day (Choice B) falls short of the recommended range. Lastly, an intake of 3000 to 3500 mg per day (Choice D) exceeds the recommended upper limit, potentially exacerbating fluid retention and high blood pressure.
3. Which organ produces and secretes bicarbonate ions and insulin?
- A. Stomach
- B. Pancreas
- C. Large intestine
- D. Small intestine
Correct answer: B
Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.
4. A nurse is caring for an antepartum client who has iron-deficiency anemia. When teaching the client about nutrition, the nurse should emphasize the need for an increased intake of which of the following foods?
- A. Milk and cheese
- B. Red meat and organ meat
- C. Fresh fruits
- D. Whole grain breads
Correct answer: B
Rationale: The correct answer is red meat and organ meat. These foods are rich sources of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Red meat and organ meat can significantly help in increasing the iron levels in individuals with iron-deficiency anemia, especially in antepartum clients. Fresh fruits, while nutritious, do not provide high amounts of iron. Milk and cheese are not the best sources of iron for individuals with iron-deficiency anemia. Whole grain breads also do not contain as much bioavailable iron as red meat and organ meat.
5. The nurse’s most unique tool in working with the emotionally ill client is his/her
- A. theoretical knowledge
- B. personality make up
- C. emotional reactions
- D. communication skills
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
