The nurse claim that a 4 -litre drip with a Drip Factor of \( 20 \mathrm{gtt} / \mathrm{ml} \) and a drip rate of \( 300 \mathrm{gtt} / \mathrm{min} \) will take mrore than 266 minutes to finish. The doctor claim that the drip will take less than 266 minutes to Use calculations to verify who is correct.

To determine who is correct, we need to calculate the total time required for a 4-litre drip to be administered at a drip rate of \(300 \mathrm{gtt/min}\). 1. First, we need to convert \(4\, \text{litres}\) to millilitres, since the drip factor is given in gtt/ml: \[ 4 \, \text{litres} = 4000 \, \text{ml} \] 2. Next, we can calculate the total number of drops required using the drip factor: \[ \text{Total drops} = \text{Total volume (ml)} \times \text{Drip Factor (gtt/ml)} \] \[ \text{Total drops} = 4000 \, \text{ml} \times 20 \, \text{gtt/ml} = 80000 \, \text{gtt} \] 3. Now, we find out how long it will take to administer the total volume at \(300 \text{gtt/min}\): \[ \text{Total time (min)} = \frac{\text{Total drops}}{\text{Drip rate (gtt/min)}} \] \[ \text{Total time (min)} = \frac{80000 \, \text{gtt}}{300 \, \text{gtt/min}} \approx 266.67 \, \text{minutes} \] So, the calculated time is approximately \(266.67\) minutes, which means the nurse is correct in saying it will take more than \(266\) minutes, while the doctor is incorrect.
