To determine the rate of drops per minute (gtts/min) for an infusion, you can use the following calculation:

  1. Convert the infusion rate from milliliters per hour to milliliters per minute. Since there are 60 minutes in an hour, you can divide the number of milliliters per hour by 60. For this question, it’s calculated as follows:

( 150 , \text{ml/hour} \div 60 , \text{minutes/hour} = 2.5 , \text{ml/min} )

  1. Next, since the infusion is delivered using 10 drops per milliliter (gtts/ml) tubing, you multiply the milliliters per minute by the number of drops per milliliter:

( 2.5 , \text{ml/min} \times 10 , \text{gtts/ml} = 25 , \text{gtts/min} )

This means the patient would receive 25 drops per minute. The answer of 100 gtts/min does not match this calculation, as it reflects a different infusion rate or tubing factor. The calculation indicates a clear understanding of the relationship between ml,
