Prescription Order: 1g in 50 mL to infuse over 30 minutes; gtt factor= 15gtts/1mL. How many drops per minute will you infuse?
The Correct Answer is ["25"]
Step 1: Convert the total volume to be infused from grams to milliliters. Since 1 gram is equivalent to 1,000 milligrams (mg), then 1 gram is equal to 1,000 mg. Therefore, 1g in 50 mL is equivalent to 1,000 mg in 50 mL.
Step 2: Determine the total infusion time in minutes. Since the order is to infuse over 30 minutes, the total infusion time is 30 minutes.
Step 3: Calculate the rate of infusion in milliliters per minute (mL/min). This is done by dividing the total volume in milliliters by the total time in minutes. So, (50 mL ÷ 30 min) equals approximately 1.67 mL/min.
Step 4: Calculate the number of drops per minute. This is done by multiplying the rate of infusion in mL/min by the drop factor in drops/mL. So, (1.67 mL/min × 15 gtt/mL) equals approximately 25 drops per minute. Therefore, you will infuse approximately 25 drops per minute.

Correct Answer is C
Explanation
Choice A rationale
The dosage of Methadone 40.0 mg orally twice a day does not seem unusually low. Methadone is a potent opioid medication used for pain management and the treatment of opioid dependence. Its dosage should be individualized based on the patient’s condition and response to treatment16.
Choice B rationale
The abbreviation “BID” is not listed as a “Do not use” abbreviation. It is a commonly used medical abbreviation that stands for “bis in die,” which means “twice a day” in Latin16.
Choice C rationale
Trailing zeros should be avoided when writing medication orders. Writing “40.0 mg” instead of “40 mg” can lead to dosing errors if the decimal point is not seen, potentially resulting in a tenfold overdose16.
Choice D rationale
There is a need to contact the provider to clarify the order due to the potential for dosing errors associated with the use of trailing zeros16.
