1. Which positive ion is most prevalent in intracellular fluid?

• A. Calcium
• B. Potassium
• C. Sodium
• D. Magnesium

Correct answer: B

Rationale: The correct answer is Potassium (K+). Potassium is the predominant cation found within cells, making it the most prevalent positive ion in intracellular fluid. Calcium, sodium, and magnesium are also essential ions in the body, but they are not as abundant in intracellular fluid. Calcium is vital for bone health and muscle function, sodium helps in maintaining fluid balance and nerve function, and magnesium is involved in numerous biochemical reactions.

3. Extracellular fluid includes:

• A. plasma and intracellular fluid.
• B. interstitial and intracellular fluids.
• C. plasma and interstitial fluid.
• D. plasma, interstitial fluid, and intracellular fluid.

Correct answer: C

Rationale: The correct answer is C: 'plasma and interstitial fluid.' Extracellular fluid consists of all body fluids outside the cells, primarily including plasma (the liquid component of blood) and interstitial fluid (the fluid between cells). Choices A, B, and D are incorrect because intracellular fluid is located within the cells, not in the extracellular fluid compartment.
