The healthcare provider prescribes hydromorphone 1 mg intravenously (IV) every 3 hours for an older client after hip replacement surgery. The nurse prepares the prescribed dose from an ampule labeled, "Hydromorphone Injection 2 mg/mL." Additional instructions for opiate naive clients recommend diluting the dosage with 3 mL of sterile normal saline (NS) for IV push over 2 to 3 minutes. How many mL is the total volume of diluted medication?
(Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["3.5"]
To calculate the total volume of diluted medication, we need to use the formula:
Total volume (mL) = Drug volume (mL) + Diluent volume (mL)
First, we need to calculate the drug volume by dividing the dose by the concentration. In this case, 1 mg of hydromorphone is equivalent to 0.5 mL of hydromorphone injection.
Plugging in the given values, we get:
Total volume (mL) = 0.5 mL + 3 mL
Simplifying, we get:
Total volume (mL) = 3.5 mL

Correct Answer is ["7200"]
Explanation
To calculate the amount of heparin received, we need to use the formula:
Amount (units) = Infusion rate (mL/h) x Time (h) x Concentration (units/mL)
First, we need to calculate the concentration of heparin in the solution by dividing the total units by the total volume. In this case, it is 20,000 units / 500 mL.
Plugging in the given values, we get:
Amount (units) = 15 mL/h x 12 h x 20,000 units / 500 mL
Simplifying, we get:
Amount (units) = 7,200 units
