A healthcare provider prescribes one 250 mg capsule of amoxicillin to be administered tid for 5 days to a client.
Calculate the number of capsules of amoxicillin required for 5 days.

To answer this question, we need to calculate the infusion rate in mL per hour by using the following formula²:

Infusion rate (mL/h) = Dose (mcg/kg/min) × Weight (kg) × 60 min/h × Volume (mL) / Concentration (mcg/mL)

In this case, the infusion rate is:

Infusion rate (mL/h) = 3 mcg/kg/min × 70 kg × 60 min/h × 250 mL / 2500 mg

We need to convert lb to kg by dividing by 2.2

Infusion rate (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / 2500 mg

We need to convert mg to mcg by multiplying by 1000:

Infusion rte (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / (2500 mg × 1000 mcg/mg)

We can simplify the equation by canceling out some units and numbers:

Infusion rate (mL/h) = 3 × 154 × 250 / (2.2 × 2500 × 1000)

We can use a calculator to get the final answer:

Infusion rate (mL/h) = 12.6363636363636 mL/h

The amount of ampicillin in one dose is 390 mg.

This answer is correct because it is based on a series of multiplication and division calculations. The nurse should follow these steps to determine the amount of ampicillin in one dose:

1) Multiply the prescribed dose per kilogram per day by the child's weight in kilograms to get the total dose per day in milligrams, as follows:

150 mg/kg/day x 10.4 kg = 1560 mg/day

Therefore, the child needs 1560 mg of ampicillin per day.

2) Divide the total dose per day by the number of doses per day to get the amount of each dose in milligrams, as follows:

1560 mg/day / 4 doses/day = 390 mg/dose

Therefore, the amount of ampicillin in one dose is 390 mg.
