1. How much energy is required to raise the temperature of one kilogram of water by 1°C?

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.

2. Why would a person who eats a bowl of oatmeal for breakfast every day most likely be making a food choice based on ___?

Correct answer: A

Rationale: The correct answer is A: habit. Eating the same food regularly often stems from habit, which is a behavior that is repeated regularly and tends to occur subconsciously. Choice B, availability, is incorrect as it refers to the accessibility of a particular food rather than the frequency of consumption. Choice C, body image, is also incorrect as this term relates to how one perceives their own body rather than their food choices. Choice D, environmental concerns, is unrelated to the scenario provided, which is about the frequency of choosing oatmeal for breakfast.

3. Which nutrient is an example of a macronutrient?

Correct answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.

4. What is the priority assessment for a child with suspected appendicitis?

Correct answer: D

Rationale: The priority assessment for a child with suspected appendicitis is 'Pain level.' Evaluating the pain level, particularly in the lower right quadrant, is crucial as it helps in determining the severity of the condition, leading to prompt diagnosis and treatment. Monitoring temperature, heart rate, and respiratory rate are important aspects of assessment; however, they are secondary to assessing the pain level in cases of suspected appendicitis. Pain assessment is key in diagnosing this condition since the classic presentation includes abdominal pain that often starts around the umbilicus and then localizes to the right lower quadrant.

5. Approximately how many grams does a normal half-cup vegetable portion weigh?

Correct answer: C

Rationale: A normal half-cup vegetable portion usually weighs around 100 grams. This weight is a standard measurement for a half-cup serving of vegetables, making choice C the correct answer. Choices A, B, and D are incorrect as they do not align with the typical weight of a half-cup vegetable portion.
