If there are 250 bottles of intravenous fluid and per day 25 injections are given then how many days will the total supply last?

Appeared in: AIIMS Raipur - 2017 (shift-2)

Explanation

The problem requires calculating the duration a supply will last given a total quantity and a daily consumption rate.
The correct method is to divide the total number of items by the number of items used per day.
Applying this to the question: 250 total bottles divided by 25 bottles used per day equals 10.
Therefore, the supply of intravenous fluid will last for 10 days.

Option A: This is incorrect. If the supply lasted only 3 days, the total number of bottles used would be 3 days × 25 bottles/day = 75 bottles, not 250.
Option B: This is incorrect. If the supply lasted 5 days, the total number of bottles used would be 5 days × 25 bottles/day = 125 bottles, not 250.
Option D: This is incorrect. If the supply lasted 8 days, the total number of bottles used would be 8 days × 25 bottles/day = 200 bottles, not 250.

Visual 1: No visual is required for this question type as it is a straightforward calculation problem.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Basic arithmetic and inventory calculation in a healthcare setting as background academic context rather than a clinical decision trigger.
Accurate inventory management is crucial in any healthcare setting to prevent stockouts of essential supplies like IV fluids, which can directly impact patient safety and care.
Nurses are often responsible for monitoring and managing unit-level supplies, making basic inventory calculations a practical and necessary skill.
What if? If the lead time to receive a new shipment of IV fluid was 12 days, the current 10-day supply would be insufficient. This would necessitate an urgent order to prevent a stockout and potential disruption to patient treatment.

How to Approach the Question

First, identify the key numbers provided in the problem: the total quantity of the item and the rate of consumption.
The total quantity is 250 bottles of intravenous fluid.
The rate of consumption is 25 injections (and thus 25 bottles) per day.
Recognize that the question asks for the duration the supply will last, which is a division problem.
Set up the equation: Total Supply ÷ Daily Consumption.
Calculate the result: 250 ÷ 25 = 10.
