Practice Question
A nurse is preparing to administer cefadroxil oral suspension 15 mg/kg PO for one dose to a client who weighs 98 lb. Available is cefadroxil 250 mg/5 ml.. How many mL will be administered? Round to the nearest tenth.
Answer Choices:
Correct Answer:
13.2
Rationale:
1️⃣ Convert pounds to kilograms
Use your preferred factor: 1 lb ≈ 0.45 kg
98 lb × 0.45 = 44.1 kg
2️⃣ Find the prescribed dose in mg
Order: 15 mg/kg
15 mg × 44.1 kg = 661.5 mg
3️⃣ Use the concentration to find mL
Available: 250 mg in 5 mL
That’s:
250 mg ÷ 5 mL = 50 mg/mL
Now:
661.5 mg ÷ 50 mg/mL = 13.23 mL
4️⃣ Round to the nearest tenth
13.23 mL → 13.2 mL
