1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

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. How much extra protein (above RDA) is safe to consume?

Correct answer: A

Rationale: Consuming up to twice the Recommended Dietary Allowance (RDA) of protein is generally considered safe for most people, although it may vary depending on individual health conditions.

3. Starting material for sex hormones:

Correct answer: A

Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.

4. What is the recommended dietary intervention for a patient with hyperlipidemia?

Correct answer: C

Rationale: Increasing dietary fiber can help reduce cholesterol levels in patients with hyperlipidemia.

5. Carmen discovers that the DASH diet contains more fiber and ____ compared to that of the typical American diet.

Correct answer: C

Rationale: The correct answer is C: 'potassium.' The DASH diet is rich in potassium, which helps lower blood pressure, making it more effective than the typical American diet, which is often low in this essential mineral. Choice A, 'vitamin C,' is incorrect as the comparison is about fiber and another nutrient, not vitamin C. Choice B, 'iron,' is incorrect as the discussion is about fiber and a mineral that helps lower blood pressure, not iron. Choice D, 'sodium,' is incorrect as the DASH diet actually focuses on reducing sodium intake for better blood pressure control, so it wouldn't be a nutrient found in higher amounts compared to the typical American diet.
