A. 2196
B. 452
C.16
D.22
E.4.5 x 105

Answer 1

To calculate the dose for a 166-lb person, convert the weight to kilograms and multiply by the recommended dose, resulting in approximately 452 mg of Elixophyllin.

Step-by-step explanation:

The question asks to calculate the dose of Elixophyllin in milligrams for a 166-lb person, given the recommended adult dose is 6.00 mg/kg of body mass and the conversion factor 1 lb = 453.59 g. First, convert the person's weight from pounds to kilograms:

166 lb × (453.59 g/lb) = 75316.34 g
75316.34 g ÷ (1000 g/kg) = 75.316 kg

Now, calculate the necessary dose:

75.316 kg × 6.00 mg/kg = 451.896 mg

Therefore, the dose for a 166-lb person is approximately 452 mg.
