(b) The recommended adult dose of Elixophyllin®, a drug used to treat asthma, is 6 mg/kg of body mass. Calculate the dose in milligrams for a 185-lb person.
Guida verificata passo dopo passo1
Convert the body mass from pounds to kilograms using the conversion factor: 1 lb = 0.453592 kg.
Calculate the body mass in kilograms by multiplying 185 lb by the conversion factor.
Use the recommended dose of 6 mg/kg to calculate the total dose in milligrams.
Multiply the body mass in kilograms by the dose per kilogram to find the total dose in milligrams.
Ensure the units are consistent and check the calculation for accuracy.

Conversion Factors
Dosage Calculation
Dosage calculation involves determining the appropriate amount of medication based on a person's weight and the recommended dosage per unit of weight. In this case, the dosage is specified as 6 mg for every kilogram of body mass. By multiplying the converted weight in kilograms by the dosage per kilogram, one can find the total dose in milligrams.
