Which term describes the standardized system for measurements used in healthcare?

• A. Active Listening
• B. Metric System
• C. Therapeutic Communication
• D. Hearing Loss

Answer: (B)

The main idea is that healthcare relies on a universal, decimal-based measurement system to keep data consistent across people and settings. The metric system, also known as the International System of Units (SI), uses units like kilograms, meters, and liters, making conversions straightforward (for example, 1 kilogram equals 1000 grams, 1 liter equals 1000 milliliters). This consistency is essential for accurate dosing, interpreting lab results, and documenting vitals, helping prevent mistakes that can arise from mixing different unit systems. The other terms describe communication skills or a health condition rather than a measurement framework, so they don’t address how measurements are standardized in clinical practice.
