Explanation

The Infant Mortality Rate (IMR) is defined as the number of deaths of infants (children under one year of age) occurring in a given year.
The denominator for this rate is the total number of live births that occurred in the same year.
The rate is expressed per 1,000 live births to allow for standardized comparison across different populations and time periods.
IMR is a sensitive indicator of the overall health of a population, reflecting factors like maternal health, quality of medical care, socioeconomic conditions, and public health practices.

Option B: The denominator is incorrect. 'Deliveries' includes both live births and stillbirths. IMR specifically uses only 'live births' to accurately measure mortality among infants who were born alive.
Option C: The multiplier is incorrect. A rate per 100,000 (1 lakh) live births is the standard for calculating the Maternal Mortality Rate (MMR), not the Infant Mortality Rate.
Option D: The denominator is incorrect. Using '1000 population' as the denominator defines the Crude Death Rate (CDR), which measures overall mortality in the general population, not specifically among infants.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition and calculation of Infant Mortality Rate (IMR) as background academic context rather than a clinical decision trigger.
IMR is one of the most important indicators of a country's health and socioeconomic status. A high IMR suggests unmet needs in nutrition, sanitation, maternal health, and access to healthcare.
Nurses play a critical role in reducing IMR through health education, promoting antenatal care, ensuring skilled birth attendance, encouraging exclusive breastfeeding, managing neonatal infections, and facilitating immunization programs.
What if the question asked for Neonatal Mortality Rate (NMR)? The answer would change to 'Number of infant deaths under 28 days of age per 1000 live births', as NMR focuses specifically on deaths in the first month of life, which are often related to prematurity, birth asphyxia, and congenital anomalies.

How to Approach the Question

This is a factual recall question that tests your knowledge of a standard public health definition.
First, identify the key term in the question: 'IMR' (Infant Mortality Rate).
Recall the precise definition of IMR. Focus on three components: the event (infant death), the timeframe (under 1 year), and the denominator (per 1000 live births).
Evaluate each option against this precise definition.
Eliminate options with incorrect denominators, such as 'deliveries', '1 lakh births', or '1000 population'.
Select the option that correctly states the rate is per 1000 live births.
