ATI Nutrition Practice A

Correct Answer: B

Rationale: A patient's dietary order is most frequently prescribed by a physician. This is because the physician has a comprehensive understanding of the patient's medical condition and can thus determine the most suitable dietary plan. Registered dietitians often collaborate with physicians in this process, but the final prescription is made by the physician. Although registered nurses, dietetic technicians, and occupational therapists play significant roles in patient care, they typically do not prescribe diet orders.

Correct Answer: D

Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.

Correct Answer: D

Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.

Correct Answer: C

Rationale: A kilocalorie count is the correct answer as it involves directly observing a client's food intake, which is often used in hospitals to accurately assess nutritional intake and ensure it meets dietary requirements. A food diary (Choice A) is typically self-reported by the client and not directly observed. A 24-hour recall (Choice B) is also usually self-reported and relies on a client's memory of the past 24 hours, which can be unreliable. A nutrient surveillance record (Choice D) is a broader term for tracking nutrient intake in a population and is not specific to the direct observation of an individual's food intake.

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.
