**Dose Calculation for Elixophyllin**

**Question:**

The recommended adult dose of Elixophyllin®, a drug used to treat asthma, is 6.00 mg/kg of body mass. Calculate the dose in milligrams for a 134-lb person.

**Choices:**
A) 20  
B) 1,773  
C) 1.8  
D) 365  
E) 3.6 × 10^5

**Solution:**

1. First, convert the body weight from pounds to kilograms. 
   - 1 pound (lb) = 0.453592 kilograms (kg)
   - Therefore, 134 lb * 0.453592 kg/lb = 60.78112 kg (approx 60.78 kg)

2. Next, calculate the dose in milligrams using the dose recommendation.
   - Dose = 6.00 mg/kg
   - Therefore, dose for a 60.78 kg person = 6.00 mg/kg * 60.78 kg 
   - = 364.68 mg (approx 365 mg)

Thus, the correct answer is **D) 365**.
