ATI Proctored Nutrition Exam 2019
1. Why do older adult female clients need less iron than younger adult female clients?
- A. The need for iron decreases because older female clients produce more red blood cells.
- B. The need for iron decreases with age because older female clients carry oxygen more efficiently.
- C. The need for iron decreases with age because older female clients experience menopause.
- D. The need for iron decreases with age because older female clients exercise more.
Correct answer: C
Rationale: The correct answer is C. Older adult female clients need less iron than younger adult female clients because as women go through menopause, they no longer lose blood through menstruation, leading to a reduced need for iron. Choice A is incorrect because producing more red blood cells does not directly correlate with needing less iron. Choice B is incorrect as carrying oxygen more efficiently does not necessarily decrease the need for iron. Choice D is incorrect as exercising more does not explain the decreased need for iron in older adult female clients.
2. When assessing for criteria that signify malnutrition risk, which element would most likely be included as part of the functional assessment data?
- A. severity of illness
- B. presence of pressure sores
- C. localized edema
- D. generalized weakness
Correct answer: D
Rationale: Generalized weakness is a key indicator of malnutrition and is often assessed as part of functional status, reflecting muscle wasting and reduced physical function. The other choices, such as severity of illness, presence of pressure sores, and localized edema, are important factors to consider in a clinical assessment but are not primarily indicative of malnutrition risk. Generalized weakness directly relates to the functional impact of malnutrition on physical performance.
3. Which suggestion is most appropriate to increase calorie intake for a patient with stomach cancer, aiming to prevent weight loss and wasting?
- A. Replace whole fat milk with skim milk or water
- B. Avoid peanut butter and other nuts
- C. Choose high-fat meat instead of lean meat
- D. Limit alcohol intake to two drinks per day
Correct answer: C
Rationale: The correct answer is C: Choose high-fat meat instead of lean meat. High-fat meats are more calorie-dense than lean meats, which makes them a good choice for increasing calorie intake. This is crucial for patients with stomach cancer who want to avoid weight loss and wasting. Choice A is incorrect because skim milk or water contains fewer calories than whole fat milk. Choice B is also incorrect because peanut butter and nuts are high in calories and therefore should not be avoided when trying to increase calorie intake. Finally, choice D is not a good suggestion to increase calorie intake as alcohol does not provide the necessary nutrients needed for a balanced diet. In fact, excessive alcohol can harm the liver and other organs, and it's not a reliable source of calories.
4. What is the most significant dietary influence on the development of dental caries?
- A. Carbohydrates
- B. Vitamins
- C. Minerals
- D. Fats
Correct answer: A
Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
5. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
