Explanation

The Net Reproduction Rate (NRR) of 1 indicates replacement-level fertility, where a population replaces itself from one generation to the next, eventually leading to stabilization.
The Couple Protection Rate (CPR) is the percentage of eligible couples using contraception.
To achieve an NRR of 1, demographers and public health experts estimate that the CPR must exceed 60%.
Among the given choices, 'More than 55%' is the only option that correctly reflects this required threshold.

Option A: A Couple Protection Rate of more than 40% is insufficient to bring down the fertility rate to the replacement level (NRR=1).
Option B: A 100% Couple Protection Rate is an unrealistic and unattainable goal in any population. It is also not necessary to achieve an NRR of 1, as not all couples need to use contraception to reach replacement level.
Option D: A CPR of more than 42% is too low to achieve an NRR of 1. According to Park's Textbook of Preventive and Social Medicine, this was an earlier target for India (for the year 1990) and not the level required for population stabilization.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The concept tested is the relationship between the Couple Protection Rate (CPR) and the Net Reproduction Rate (NRR), specifically the level of contraceptive prevalence required to achieve replacement-level fertility as background academic context rather than a clinical decision trigger.
Understanding the relationship between CPR and NRR is fundamental for community health nurses and public health officials to evaluate the effectiveness of family welfare programs.
These demographic indicators are critical for national and regional health planning, guiding policies on resource allocation for maternal and child health (MCH) services and family planning initiatives.
A high CPR is a key objective in reducing maternal and infant mortality rates by preventing unwanted and high-risk pregnancies.

How to Approach the Question

First, identify the key terms in the question: 'Couple Protection Rate' (CPR) and 'Net Reproduction Rate' (NRR) of one.
Recall the definitions. NRR=1 means replacement-level fertility, where the population stabilizes. CPR is the percentage of couples using contraception.
Access your knowledge of community health and demographic targets. Remember the approximate CPR needed to achieve replacement-level fertility.
The widely accepted target for achieving NRR=1 is a CPR of about 60%.
Evaluate the given options based on this target. 'More than 40%' and 'More than 42%' are too low. '100%' is unrealistic.
Select the option that best aligns with the established demographic goal. 'More than 55%' is the most plausible choice as it encompasses the target of 60%.
