Explanation

The Human Development Index (HDI) is a normalized composite index, meaning its value is mathematically scaled to fit within a predefined range.
The standard range for the HDI is from 0 (lowest human development) to 1 (highest human development).
This normalization allows for direct and standardized comparisons of human development levels across different countries and over time.
The index is calculated from three dimensions: life expectancy, education, and per capita income, each of which is first converted to an index between 0 and 1.

Option B: A range of 0-10 is not used for the HDI. This scale is not standard for major international development indices.
Option C: A range of 0-100 is incorrect for the HDI. This scale is characteristic of the Physical Quality of Life Index (PQLI), which is a different measure of well-being.
Option D: A range of 0-1000 is not a standard scale for any major development index, including the HDI.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Range of the Human Development Index (HDI) as background academic context rather than a clinical decision trigger.
A country's HDI level is strongly correlated with the health of its population and the robustness of its healthcare system. Nurses working in countries with lower HDI scores often face challenges like limited resources, higher burdens of communicable diseases, and poor infrastructure.
Understanding HDI helps public health nurses and policymakers identify regions that need greater investment in health, education, and economic opportunities to improve overall well-being.
What if? If a country's HDI score improves from the 'Medium' to 'High' category, a nurse would likely observe changes such as lower infant and maternal mortality rates, increased access to advanced medical technology, better health literacy among patients, and a shift in disease burden from infectious to chronic non-communicable diseases.

How to Approach the Question

First, identify the key term in the question, which is 'Human Development Index (H.D.I.)'.
Recall the definition and fundamental properties of the HDI. This is a factual recall question.
Remember that the HDI is a standardized, composite index designed for international comparison.
Consider what 'standardized' or 'normalized' implies for an index's scale. It usually means a simple, universal range like 0 to 1 or 0 to 100.
Recall or deduce that the HDI uses the simplest normalized scale, which is 0 to 1.
Evaluate the options and eliminate those that represent incorrect scales. The 0-100 scale is a common distractor as it's used for the PQLI.
