A primary healthcare provider prescribes 1.5 L of normal saline (NS) to be given over 24 hours for continuous intravenous (IV) infusion to a client who has diarrhea.
What should be the rate of infusion that is required to be set in the infusion pump?

To find the milliliters per dose, you need to use the formula for dosage calculation:

Volume (mL) = Dose ordered (mg) / Concentration (mg/mL) x Volume available (mL)

Since the dose ordered is 0.5 grams, the concentration is 125 mg/5 mL, and the volume available is 5 mL, plug in these values into the formula:

Volume (mL) = 0.5 grams / 125 mg/5 mL x 5 mL

However, before you can simplify and solve for the volume, you need to convert the dose from grams to milligrams by multiplying by 1000:

Volume (mL) = 500 mg / 125 mg/5 mL x 5 m

Simplify and solve for the volume:

Volume (mL) = 20 mL

Therefore, the nurse should administer **20 mL** of Amoxil per dose to the patient.

To find the amount of solution to draw for one dose, you need to calculate the following:

- The body surface area (BSA) of the client in square meters (m²) using the formula: BSA (m²) = √(Height (cm) x Weight (kg) / 3600)
- The dose of allopurinol in milligrams (mg) using the formula: Dose (mg) = BSA (m²) x Prescribed dose
(mg/m²)
- The volume of solution in milliliters (mL) using the formula: Volume (mL) = Dose (mg) / Concentration (mg/mL)

First, use the formula for BSA to find the client's body surface area in square meters:

BSA (m²) = √(Height (cm) x Weight (kg) / 3600)

Since the client's height is 148 cm and weight is 55 kg, plug in these values into the formula:

BSA (m²) = √(148 cm x 55 kg / 3600)

Simplify and solve for the BSA:

BSA (m²) = 1.41 m²

Next, use the formula for dose to find the amount of allopurinol in milligrams:

Dose (mg) = BSA (m²) x Prescribed dose (mg/m²)

Since the client's BSA is 1.41 m² and the prescribed dose is 115 mg/m², plug in these values into the formula:

Dose (mg) = 1.41 m² x 115 mg/m²

Simplify and solve for the dose:

Dose (mg) = 162.15 mg

Then, use the formula for volume to find the amount of solution in milliliters:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Since the dose is 162.15 mg and the concentration is 25 mg/mL, plug in these values into the formula:

Volume (mL) = 162.15 mg / 25 mg/mL

Simplify and solve for the volume:

Volume (mL) = 6.486 mL

Therefore, the nurse should draw **6.486 mL** of solution for one dose of allopurinol.
