ATI Nutrition Proctored Exam 2023
1. Which of the following groups of vitamins are fat-soluble?
- A. vitamins B and C
- B. vitamins A and C
- C. vitamins B, E, K, D
- D. vitamins A, E, K, D
Correct answer: D
Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.
2. What is the desirable resting systolic blood pressure for adults?
- A. <130 mmHg>
- B. <105 mmHg>
- C. <120 mmHg>
- D. <140 mmHg>
Correct answer: C
Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.
3. Why is a pulse oximeter attached to Mr. Dizon's finger?
- A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
- B. To check the level of the patient's tissue perfusion
- C. To measure the effectiveness of the patient's anti-hypertensive medications
- D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop
Correct answer: D
Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
4. Which of the following provides greater flexibility, better balance, more endurance, and overall better health and greater longevity for older adults?
- A. Eating balanced meals
- B. Not smoking or drinking alcohol
- C. Daily physical activity
- D. Increased intake of calcium and iron
Correct answer: C
Rationale: The correct answer is C: Daily physical activity. Daily physical activity contributes to better flexibility, balance, endurance, and overall health, helping older adults maintain independence and reduce the risk of chronic diseases. Choices A, B, and D, although important for overall health, do not specifically address the benefits of greater flexibility, better balance, more endurance, and greater longevity associated with daily physical activity.
5. Which medical problem is not generally associated with malnutrition?
- A. incontinence
- B. pressure sores
- C. celiac disease
- D. major surgery
Correct answer: A
Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.
