1. **State the problem:** Ignjat weighs 76 kg and the recommended dosage of Rydalen is 20 mg per kg of body weight. The drug concentration is 50 mg/mL. We need to find how many mL of the drug should be administered. 2. **Formula used:** \[ \text{Dosage (mg)} = \text{Weight (kg)} \times \text{Dosage per kg (mg/kg)} \] \[ \text{Volume (mL)} = \frac{\text{Dosage (mg)}}{\text{Concentration (mg/mL)}} \] 3. **Calculate the total dosage:** \[ 76 \times 20 = 1520 \text{ mg} \] 4. **Calculate the volume to administer:** \[ \frac{1520}{50} = 30.4 \text{ mL} \] 5. **Answer:** Ignjat needs to be administered **30.4 mL** of Rydalen.
