Total number of deaths below one year of age per thousand live births is called:

Explanation

The Infant Mortality Rate (IMR) is the standard measure for the number of deaths in children under one year of age.
The rate is calculated per 1,000 live births within a specific time period, usually a year.
This definition precisely matches the parameters given in the question stem.
It is a universally accepted indicator of population health and socioeconomic status.

Option A: The Perinatal Mortality Rate covers a different time frame, specifically from 22 weeks of gestation through the first 7 days of life, and its denominator includes total births (live births + stillbirths).
Option C: The Neonatal Mortality Rate only measures deaths within the first 28 days of life, which is a much shorter period than the one year specified in the question.
Option D: While 'Infant death rate' is colloquially understood, 'Infant mortality rate' is the precise, standardized technical term used in epidemiology and public health for official statistics and international comparisons.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definitions of key child mortality indicators as background academic context rather than a clinical decision trigger.
The Infant Mortality Rate (IMR) is one of the most important indicators of a country's overall health and quality of life.
A high IMR often signals problems with maternal health, access to quality healthcare, socioeconomic conditions, and public health policies.
Nurses play a crucial role in reducing IMR through antenatal care, health education for mothers, promoting immunizations, and providing skilled care during and after birth.

How to Approach the Question

This is a factual recall question that tests your knowledge of standard epidemiological definitions.
First, break down the question into its key components: 'deaths', 'below one year of age', and 'per thousand live births'.
Next, systematically evaluate each option against these components.
Recall the specific time frame for each mortality rate: Perinatal (around birth), Neonatal (first 28 days), and Infant (first year).
Eliminate 'Perinatal mortality rate' and 'Neonatal mortality rate' because their time frames do not match 'below one year'.
Between 'Infant mortality rate' and 'Infant death rate', recognize that 'Infant mortality rate' is the standard, technical term used in healthcare statistics.
