If a state has 500000 live births in year 2020-21, and 500 maternal deaths were reported during this period, then, what would be the MMR of the state for this period?

1. A

   600

2. B

   450

3. C

   150

4. D

   100

Explanation

• The Maternal Mortality Ratio (MMR) is defined as the number of maternal deaths per 100,000 live births.
• The formula to calculate MMR is: (Number of Maternal Deaths / Number of Live Births) × 100,000.
• Given 500 maternal deaths and 500,000 live births, the calculation is (500 / 500,000) × 100,000.
• Simplifying the fraction gives (1 / 1000) × 100,000, which equals 100.
• Thus, the MMR is 100 maternal deaths per 100,000 live births.

Why Other Options Were Wrong

• Option A: An MMR of 600 would imply a much higher number of maternal deaths. With 500,000 live births, an MMR of 600 would mean (600 × 500,000) / 100,000 = 3,000 maternal deaths, not 500.
• Option B: An MMR of 450 is incorrect. For 500,000 live births, an MMR of 450 would correspond to (450 × 500,000) / 100,000 = 2,250 maternal deaths.
• Option C: An MMR of 150 is incorrect. This would require (150 × 500,000) / 100,000 = 750 maternal deaths, whereas only 500 were reported.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Calculation of Maternal Mortality Ratio (MMR) as background academic context rather than a clinical decision trigger.
• MMR is a critical indicator of the quality of a country's or state's healthcare system, particularly maternal and child health services.
• Nurses, especially in community health and obstetrics, play a vital role in collecting accurate data on births and maternal deaths, which is essential for calculating MMR.
• A high MMR signals a need for targeted public health interventions, such as improving access to skilled birth attendants, emergency obstetric care, and postnatal care, all of which are core nursing responsibilities.

How to Approach the Question

• First, identify the question type. This is an analytical question that requires a calculation.
• Read the question carefully to extract the given data: Number of live births = 500,000 and Number of maternal deaths = 500.
• Recall the specific formula for the Maternal Mortality Ratio (MMR): (Maternal Deaths / Live Births) × 100,000.
• Substitute the given values into the formula: (500 / 500,000) × 100,000.
• Perform the calculation step-by-step to avoid errors. Simplify the fraction first: 500/500,000 = 1/1000. Then multiply by 100,000.
• Compare your calculated result (100) with the given options and select the matching one.
