Maternal death rate is expressed deaths per

Correct option is A

Maternal Mortality Rate (MMR) is defined as the number of maternal deaths per 100,000 live births, but in basic options, it's often framed as 1,000 live births in academic contexts. This helps standardize comparison across regions. Explanation of each option: • (a) 1,000 live births – Correct. Though globally MMR is commonly calculated per 100,000 live births, many nursing exams simplify this to per 1,000 live births for easier comparison. • (b) 1,000 pregnancies – Incorrect. MMR is based on live births, not total pregnancies, as it's difficult to track miscarriages/abortions accurately. • (c) 10,000 live births – This would make the ratio too diluted and is not the standard reference unit. • (d) 10,000 pregnancies – Also incorrect, as it doesn't reflect actual birth outcomes tied to maternal mortality.
