1. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

Correct answer: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.

2. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?

Correct answer: D

Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.

3. A nurse is educating a group of older adults in a community center on weight management using the BMI scale. Using the client's height and weight to calculate BMI, which of the following clients has a healthy BMI?

Correct answer: A

Rationale: To determine a healthy BMI, we need to calculate it using the formula: BMI = weight (lbs) / height^2 (inches) x 703. For choice A, BMI = 128 / (70 x 70) x 703 = 18.38, which falls within the healthy BMI range of 18.5-24.9. Therefore, choice A is correct. Choices B, C, and D have BMIs of 22.8, 27.1, and 26.1, respectively, which are outside the healthy range. Thus, choices B, C, and D are incorrect.

4. During the first 24 hours after the thermal injury, you should assess Sergio for:

Correct answer: D

Rationale: During the initial phase after a thermal injury, the major concern is the release of potassium due to cell damage, leading to hyperkalemia. Hypernatremia is not typically a primary concern in the immediate post-injury phase. Hyponatremia is less likely to occur initially after a burn injury. Therefore, the correct assessment for Sergio during the first 24 hours after the thermal injury would be hyperkalemia and hypernatremia.

5. Which foods increase iron absorption when consumed with nonheme iron? (SATA)

Correct answer: D

Rationale: Kiwi and strawberries are high in vitamin C, which increases iron absorption.
