Calculate the flow rate I mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 25,000 units of Heparin in 250 mL to infuse at 11 mL/hr. Calculate rate in units/hr.

Given:

Ordered dose of Dopamine: 3 mcg/kg/min

Child's weight: 41.8 lbs

Concentration of Dopamine: 400 mg in 250 mL D5W

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 41.8 lbs x 0.453592 kg/lb = 18.935 kg

Step 2: Calculate the total dose of Dopamine in mcg/min:

Total dose (mcg/min) = Ordered dose (mcg/kg/min) x Child's weight (kg)

Total dose (mcg/min) = 3 mcg/kg/min x 18.935 kg

Total dose (mcg/min) = 56.805 mcg/min

Step 3: Convert mcg to mg:

Total dose (mg/min) = Total dose (mcg/min) / 1000 mcg/mg

Total dose (mg/min) = 56.805 mcg/min / 1000 mcg/mg

Total dose (mg/min) = 0.056805 mg/min

Step 4: Calculate the total dose in mg/hr:

Total dose (mg/hr) = Total dose (mg/min) x 60 min/hr

Total dose (mg/hr) = 0.056805 mg/min x 60 min/hr

Total dose (mg/hr) = 3.4083 mg/hr

Step 5: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total dose (mg/hr) / Concentration (mg/mL)

Infusion rate (mL/hr) = 3.4083 mg/hr / (400 mg/250 mL)

Infusion rate (mL/hr) = 3.4083 mg/hr x (250 mL/400 mg)

Infusion rate (mL/hr) = 2.1301875 mL/hr

Step 6: Round to the nearest tenth:

Infusion rate (mL/hr) ≈ 2.1 mL/hr

A) The healthcare provider's order
While the healthcare provider's order is crucial for ensuring that the correct drug and dosage are administered, it is not something that would be written on the reconstituted drug label. The reconstituted drug label is intended to communicate specific information about the reconstitution process and the product's current status, but the order itself is typically not part of this information.

B) Diluent
When reconstituting a medication, it is essential to note the diluent used. The diluent refers to the liquid used to mix the powdered medication and turn it into a solution or suspension. Including this information on the drug label ensures that anyone handling the medication can verify the proper solution used for reconstitution, which is important for both correct administration and stability of the drug.

C) Date to discard
After a medication has been reconstituted, it often has a limited shelf life, and it is important to write the date to discard on the drug label. This ensures that the medication is used within its recommended time frame to avoid potential degradation or loss of potency. The discard date is especially important in hospitals or clinics where drugs are prepared in advance.

D) Initials
The nurse should always include their initials on the reconstituted drug label. This serves as a means of accountability, allowing others to know who prepared the medication. It also helps ensure proper identification in case of questions or errors regarding the preparation.
