1. How many calories are contained in a food that has 15 grams of carbohydrates, 4 grams of protein, and 10 grams of fat?

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.

2. Which of the following statements are true about iron?

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.

3. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

4. Mr. Bradley has been advised to limit his dairy product intake. What principle regarding fluid intake should be followed?

Correct answer: A

Rationale: For patients with kidney disease, it's important to manage fluid intake from all sources, including foods like gelatin and soups, which can contribute to fluid overload.

5. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
