A Doctor conducted 40 OTs in a month and 30 OTs were successful. What is the percentage of OT successful?
Appeared in: SGPGI Nursing Officer-2023
Explanation
- The question asks to calculate the percentage of successful OTs from a total number of operations.
- The formula for percentage is (Number of Successful Outcomes / Total Number of Outcomes) × 100.
- Given data: Total OTs = 40, Successful OTs = 30.
- Calculation: (30 / 40) × 100 = 0.75 × 100 = 75%.
Why Other Options Were Wrong
- Option B: This percentage corresponds to 32 successful OTs (0.80 × 40), not 30.
- Option C: This percentage corresponds to 24 successful OTs (0.60 × 40), not 30.
- Option D: This percentage corresponds to 36 successful OTs (0.90 × 40), not 30.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Percentage Calculation as background academic context rather than a clinical decision trigger.
- Calculating success rates is a fundamental skill for quality assurance and performance monitoring in healthcare settings.
- Nurses and hospital administrators use these statistics to evaluate the effectiveness of procedures, identify areas for improvement, and report on departmental performance.
- What if the number of successful OTs was 32? The success rate would then be (32/40) x 100 = 80%, making option B the correct answer.
How to Approach the Question
- Identify the 'part' (the number of successful outcomes) and the 'whole' (the total number of events).
- Recall the formula for calculating a percentage: Percentage = (Part / Whole) × 100.
- Substitute the given values into the formula: (30 / 40) × 100.
- Perform the division first: 30 ÷ 40 = 0.75.
- Multiply the result by 100 to convert the decimal to a percentage: 0.75 × 100 = 75%.
- Compare your calculated answer with the given options to find the correct one.
