ATI RN Nutrition Online Practice 2019
1. Maternal malnutrition at a critical period of development may have lifelong effects on an individual's pattern of genetic expression and on the tendency to develop obesity, which is a concept known as _____.
- A. genetic determination
- B. metabolic tolerance
- C. chromosomal influence
- D. fetal programming
Correct answer: D
Rationale: Fetal programming refers to the concept that maternal nutrition during critical periods of development can have long-term effects on an individual's health and risk of diseases like obesity.
2. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?
- A. Hypodipsia
- B. Hypernatremia
- C. Hypokalemia
- D. Osmosis
Correct answer: D
Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.
3. What describes a common physical change of aging that can affect an older adult's nutrition?
- A. reduced salivary output
- B. increased gastrointestinal motility
- C. abnormal cortisol production
- D. increase in number of taste buds
Correct answer: A
Rationale: Reduced salivary output is a common physical change in aging. This can affect an older adult's nutrition by impacting chewing, swallowing, and taste perception. The decrease in saliva production can make it harder to chew and swallow food effectively, affecting the overall eating experience. Additionally, saliva plays a role in taste perception, so a reduction in salivary output can lead to alterations in how food tastes, potentially impacting an individual's appetite and food choices. Increased gastrointestinal motility (choice B) is not typically associated with aging and would not directly affect nutrition. Abnormal cortisol production (choice C) is related to hormonal changes and is not a common physical change of aging that affects nutrition. An increase in the number of taste buds (choice D) is not a typical change associated with aging and would not have a significant impact on an older adult's nutrition.
4. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.
- A. Both the statement and the reason are correct and related.
- B. Both the statement and the reason are correct but are not related.
- C. The statement is correct, but the reason is not correct.
- D. The statement is not correct, but the reason is correct.
Correct answer: A
Rationale: Both the statement and the reason are correct and related. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.
5. What type of drug therapy is typically administered immediately after a heart attack?
- A. Antilipemic drugs
- B. Corticosteroids
- C. Diuretics
- D. Thrombolytic drugs
Correct answer: D
Rationale: Thrombolytic drugs are typically administered immediately after a heart attack to dissolve the clot blocking the coronary artery and restore blood flow to the heart muscle. Antilipemic drugs are used to lower lipid levels and prevent atherosclerosis, but they are not typically administered immediately after a heart attack. Corticosteroids are used to reduce inflammation and suppress the immune response, which are not immediate concerns after a heart attack. Diuretics are used to reduce fluid build-up and lower blood pressure, but these are not the primary concerns immediately following a heart attack.
