Transcribed Image Text:**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**.
