1. What is the first step in the scientific method?

A. Conduct an experiment
B. Make an observation and ask a question
C. Formulate a hypothesis
D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

2. A nurse is providing MyPlate education to a client newly diagnosed with diabetes mellitus. Which plate chosen by the client indicates the teaching was effective, according to the MyPlate guidelines?

A. 1/2 of the plate is filled with carbohydrate foods, 1/4 filled with protein foods, and 1/4 filled with fruits and vegetables
B. 1/2 of the plate is filled with protein foods, 1/4 filled with carbohydrates, and 1/4 filled with non-starchy vegetables
C. 1/2 of the plate is filled with carbohydrates, 1/4 filled with protein foods, and 1/4 filled with non-starchy vegetables
D. 1/2 of the plate is filled with non-starchy vegetables, 1/4 filled with protein foods, and 1/4 filled with carbohydrate foods

Correct answer: D

Rationale: The correct answer is D. This option reflects the MyPlate guidelines for managing diabetes effectively. In diabetes management, it is essential to focus on non-starchy vegetables, appropriate protein portions, and controlled carbohydrate intake. Option A places too much emphasis on carbohydrates, which may not be suitable for diabetes. Option B swaps the proportions of protein and carbohydrates, which is not in line with the recommended distribution. Option C places too much emphasis on carbohydrates and lacks the emphasis on non-starchy vegetables, making it less suitable for diabetes management.

5. Which of the following is NOT required on a food label or nutrition facts panel?

A. Nutrition facts panel
B. Ingredients in descending order by weight
C. The % RDA of ALL the vitamins and minerals in the product
D. Essential warnings, such as common allergies

Correct answer: C

Rationale: According to food labeling regulations, every food label or nutrition facts panel must include a nutrition facts panel, list of ingredients in descending order by weight, and essential warnings such as common allergies. However, it is not mandatory to list the % Recommended Daily Allowance (RDA) of ALL the vitamins and minerals in the product. Only certain vitamins and minerals, deemed significant to public health, are required to be listed. Therefore, the notion that the % RDA of ALL vitamins and minerals must be displayed is incorrect. Choices A, B, and D are required elements on a food label, making them incorrect answers.
