Phenytoin must be administered at a rate no faster than 50 mg/min. How many minutes would it take to administer 1 g?

1. Break Down the Problem

To determine how many minutes it will take to administer 1 g (1000 mg) of Phenytoin at a rate of no faster than 50 mg/min, we need to:

1. Convert the total dose from grams to milligrams (if necessary).
2. Divide the total dose by the rate of administration.

2. Relevant Concepts

• Dosage Conversion: $1 \text{ g} = 1000 \text{ mg}$
• Administration Rate: $\text{Rate} = 50 \text{ mg/min}$

3. Analysis and Detail

1. Calculate the total dose in milligrams: $\text{Total Dose} = 1 \text{ g} = 1000 \text{ mg}$

2. Calculate the time required to administer the entire dose at the specified rate: $\text{Time} = \frac{\text{Total Dose}}{\text{Rate}} = \frac{1000 \text{ mg}}{50 \text{ mg/min}} = 20 \text{ min}$

4. Verify and Summarize

• We have converted 1 g to 1000 mg successfully.
• The calculation yields 20 minutes to administer the total dose at the appropriate rate.

Final Answer

It would take 20 minutes to administer 1 g of Phenytoin at a rate of no faster than 50 mg/min.
