Explanation

Listen in Hindi

• The Infant Mortality Rate (IMR) is defined as the number of deaths of infants under one year of age per 1000 live births in a given year.
• The formula to calculate IMR is: (Number of infant deaths / Number of live births) × 1000.
• Plugging in the given values: (3000 deaths / 80000 live births) × 1000.
• The calculation yields 0.0375 × 1000, which equals 37.5.

Why Other Options Were Wrong

• Option A: This value is incorrect and would result from a miscalculation, possibly by dividing 3000 by a number larger than 80000 or an arithmetic error.
• Option C: This value is incorrect and represents a calculation error. It does not match the result from the standard IMR formula.
• Option D: This value is incorrect. It is a result of an error in the calculation and does not reflect the correct IMR based on the data provided.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Calculation of Infant Mortality Rate (IMR) as background academic context rather than a clinical decision trigger.
• IMR is a critical indicator of a nation's health and social development, reflecting the quality of maternal and child health services, sanitation, and nutrition.
• Nurses in community health and obstetrics play a vital role in reducing IMR through health education, promoting antenatal care, ensuring safe delivery practices, and providing comprehensive postnatal care.
• What if? If the question asked for the mortality rate per 100 live births instead of 1000, the calculation would be (3000 / 80000) × 100 = 3.75. It's crucial to remember that IMR is conventionally expressed per 1000 live births.

How to Approach the Question

• First, identify the key data points provided in the question: the number of infant deaths (3000) and the total number of live births (80000).
• Recall the standard formula for calculating the Infant Mortality Rate (IMR), which is (Number of infant deaths ÷ Number of live births) × 1000.
• Substitute the given values into the formula: (3000 ÷ 80000) × 1000.
• Perform the division first: 3000 / 80000 = 0.0375.
• Then, multiply the result by 1000: 0.0375 × 1000 = 37.5.
• Finally, compare your calculated answer (37.5) with the given options to find the correct one.
