1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?
- A. Semipermeable membranes.
- B. Hydration.
- C. Osmotic pressure.
- D. Perspiration.
Correct answer: C
Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.
2. What term is used to refer to the beliefs, ideals, and values that direct an organization and give it a sense of purpose?
- A. Philosophy
- B. Mission
- C. Vision
- D. Goals and Objectives
Correct answer: C
Rationale: The correct term for the beliefs, ideals, and values that direct an organization and provide it with a sense of purpose is 'Vision'. A Vision statement outlines the organization's aspirations and goals for the future. Choices A, B, and D are incorrect in this context. 'Philosophy' refers to a system of beliefs or principles, 'Mission' relates to the organization's purpose and primary objectives, and 'Goals and Objectives' are the specific targets set to accomplish the Vision.
3. A client is prescribed a 1500-calorie diet. Thirty percent of the calories are to be derived from fat. How many grams of fat should the nurse tell the client to consume per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 21
- B. 49
- C. 60
- D. 50
Correct answer: D
Rationale: To calculate the grams of fat, first, determine the calories from fat by multiplying the total calorie intake (1500 calories) by the percentage of calories from fat (30%), which equals 450 calories from fat. Since 1 gram of fat is equivalent to 9 calories, divide the total calories from fat (450) by the calories in 1 gram of fat (9) to get the answer in grams, which is 50. Therefore, the client should consume 50 grams of fat per day. Choice A (21), Choice B (49), and Choice C (60) are incorrect as they do not reflect the accurate calculation based on the given information.
4. During the first six months of lactation, a breastfeeding mother is advised to consume how many extra kcalories per day to meet energy needs?
- A. 250
- B. 330
- C. 400
- D. 470
Correct answer: B
Rationale: A breastfeeding mother is advised to consume an additional 330 kcalories per day during the first six months to support milk production and meet increased energy needs.
5. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?
- A. 1 cup grapes
- B. 1 cup shredded lettuce
- C. 1 cup cooked tomatoes
- D. 1 cup apple slices
Correct answer: C
Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.
