Correct Answer: C

Rationale: To calculate the total calories in a food item, you can use the following conversions: every 1 gram of carbohydrate provides 4 calories, 1 gram of protein provides 4 calories, and 1 gram of fat provides 9 calories. Therefore, for this food item, multiply 15 grams of carbohydrates by 4 calories/gram, 4 grams of protein by 4 calories/gram, and 10 grams of fat by 9 calories/gram. The calculation would be (15 * 4) + (4 * 4) + (10 * 9) = 60 + 16 + 90 = 166 calories. Choice A (106) is incorrect because it does not consider the calories from fat. Choice B (124) is incorrect as it underestimates the calories by not including all macronutrients. Choice D (202) is incorrect as it overestimates the calories by adding up the values incorrectly.

Correct Answer: B

Rationale: In caring for a client receiving parenteral nutrition, it is important to follow proper guidelines to ensure safety and effectiveness. Unused parenteral nutrition should be removed after 24 hours, not 12 hours, to prevent contamination and reduce the risk of infection. Option A is correct as it ensures the solution is at room temperature before infusion. Option C is essential for monitoring the client's response to parenteral nutrition. Option D is important to maintain the correct flow rate and adjust it as needed. Therefore, option B is the incorrect choice among the options provided.

Correct Answer: D

Rationale: Malnutrition can lead to a variety of physical and mental symptoms. One common manifestation of malnutrition is a decreased mental status, which includes confusion, lethargy, and cognitive impairment. Dry skin is a typical finding in malnutrition due to the lack of essential nutrients needed for skin health. Heat intolerance is not a direct consequence of malnutrition. While malnutrition can affect respiratory function, it typically leads to decreased vital capacity rather than increased. Therefore, the correct answer is decreased mental status.

Correct Answer: A

Rationale: The correct answer is A: A slice of cheese. Cheese is high in fat, sodium, and cholesterol, making it unsuitable for a low-fat, low-sodium, and low-cholesterol diet. Choices B, C, and D are more appropriate for such a diet. B: A jam sandwich can be low in fat, sodium, and cholesterol if made with whole grain bread and a low-sugar jam. C: A cup of plain popcorn is a good choice as it is low in fat and can be made without added salt. D: A small container of applesauce is also a suitable option for a low-fat, low-sodium, and low-cholesterol diet.

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.
