LPN Nutrition Practice Test

Correct Answer: D

Rationale: The Recommended Dietary Allowances (RDAs) are the best measure to describe the amounts of nutrients that should be consumed by the population. RDAs represent the average daily intake level that meets the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. Choice A, the Dietary Reference Intakes, provide a set of nutrient intake values but do not specifically address the average daily amount of a nutrient considered adequate for practically all individuals. Choice B, the Tolerable Upper Intake levels, focus on the maximum daily amount of a nutrient deemed safe for most healthy people, not the average daily amount needed. Choice C, the Estimated Average Requirements, reflect the average daily amount of a nutrient needed by half of the healthy individuals, which is not as comprehensive as the RDAs that cater to nearly all healthy people.

Correct Answer: C

Rationale: The correct answer is C: Bed rest. Implementing bed rest can be challenging, especially in active children, but it's necessary to manage the symptoms of acute glomerulonephritis. Forced fluids (choice A) may be required to maintain hydration but are not typically challenging. Increased feedings (choice B) and frequent position changes (choice D) are not primary interventions in the care of a child with acute glomerulonephritis.

Correct Answer: B

Rationale: The correct answer is monitoring blood cell counts. During chemotherapy, it is crucial to monitor blood cell counts to detect potential side effects such as neutropenia (low white blood cell count) and anemia (low red blood cell count). These conditions can increase the risk of infections and fatigue. Monitoring blood glucose levels (Choice A) is not typically a primary concern in children receiving chemotherapy unless they have pre-existing conditions like diabetes. Weight gain (Choice C) and skin elasticity (Choice D) are not directly related to monitoring the effects of chemotherapy in children. Therefore, the most important parameter to monitor in a child receiving chemotherapy is blood cell counts.

Correct Answer: B

Rationale: When a parent expresses concerns about their child's recurrent ear infections, the best course of action is to recommend a thorough evaluation by an Ear, Nose, and Throat (ENT) specialist. This specialist can conduct a comprehensive assessment to identify the underlying cause of the ear infections and provide appropriate treatment options. Choice A is incorrect because suggesting over-the-counter ear drops without a proper evaluation may not address the root cause of the issue. Choice C is also incorrect as increasing antibiotic use without understanding the specific cause can lead to antibiotic resistance and may not be necessary. Choice D is incorrect as avoiding physical activities is unrelated to addressing recurrent ear infections and is not a recommended approach.

Correct Answer: D

Rationale: The correct answer is D, essential nutrient. Essential nutrients are substances that the body needs for normal functioning but cannot produce in sufficient amounts, so they must be obtained through the diet. Nutraceuticals (choice A) are products derived from food sources that are purported to provide extra health benefits beyond basic nutrition. Metabolic nutrients (choice B) and organic nutrients (choice C) are not standard terms used to describe nutrients needed by the body. Therefore, choices A, B, and C are incorrect.
