Question

A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

5.6

Rationale :

Given:

⁕ Weight = 33 lb

⁕ Prescription = 30 mg/kg/day

⁕ Frequency = every 12 hr = 2 doses/day

⁕ Available = 200 mg/5 mL

✳️ Convert pounds to kilograms:

⁕ 33 ÷ 2.2 = 15 kg

✳️ Calculate total daily dose:

⁕ 30 mg × 15 kg = 450 mg/day

✳️ Calculate dose every 12 hours:

⁕ 450 mg ÷ 2 = 225 mg/dose

✳️ Formula:

⁕ Desired dose ÷ Dose on hand × Volume = mL to administer

✳️ Substitute:

⁕ 225 mg ÷ 200 mg × 5 mL = 5.625 mL

✳️ Round to the nearest tenth:

= 5.6 mL

Answer 6

Correct Answers:

75

Rationale :

Given:

⁕ Volume = 100 mL

⁕ Infusion time = 20 min

⁕ Drop factor = 15 gtt/mL

🔆 Formula:

⁕ gtt/min = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)

🔆 Substitute:

⁕ 100 mL × 15 gtt/mL ÷ 20 min

🔆 Calculate:

⁕ 1,500 ÷ 20

= 75 gtt/min
