Which of the following medications should be administered whole (e.g., not divided or crushed for administration)?

To find the total amount of heparin, you need to calculate the following:

- The concentration of heparin in units per milliliter
- The volume of heparin infused from 9:00 am to 11:00 am and from 11:00 am to 2:00 pm
- The amount of heparin in units from each time period and the total amount

First, divide the amount of heparin by the volume of D5W to get the concentration in units per milliliter:

25,000 units / 250 mL = 100 units/mL

Next, multiply the infusion rate by the duration to get the volume infused in each time period:

From 9:00 am to 11:00 am (2 hours), the infusion rate is 12 mL/hr:

12 mL/hr x 2 hours = 24 mL

From 11:00 am to 2:00 pm (3 hours), the infusion rate is 10 mL/hr:

10 mL/hr x 3 hours = 30 mL

Then, multiply the volume infused by the concentration to get the amount of heparin in units in each time period:

From 9:00 am to 11:00 am, the volume infused is 24 mL:

24 mL x 100 units/mL = 2400 units

From 11:00 am to 2:00 pm, the volume infused is 30 mL:

30 mL x 100 units/mL = 3000 units

Finally, add the amounts of heparin from each time period to get the total amount:

2400 units + 3000 units = 5400 units

Therefore, the patient received **5400 units** of heparin from 9:00 am to 2:00 pm.

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.
