A nurse has received an order to administer Morphine 5mg IV once immediately.
The available concentration is 2.5 mg/mL. How many mL of morphine should the nurse prepare for administration?

0.5 mL

1 mL

2 mL

4 mL

Answer and Explanation

The Correct Answer is C

Step 1: The order is to administer Morphine 5mg IV once immediately. The available concentration is 2.5 mg/mL. To find out how many mL of morphine the nurse should prepare for administration, we need to divide the ordered dose by the available concentration.

Step 2: Calculation: 5 mg ÷ 2.5 mg/mL = 2 mL So, the nurse should prepare 2 mL of morphine for administration.

Correct Answer is D

Explanation

Step 1 is to calculate the total amount of Magnesium sulfate in the solution. This is done by multiplying the amount of Magnesium sulfate per mL (which is 50g/L or 0.05g/mL) by the total volume of the solution (which is 1000mL). So, 0.05g/mL × 1000mL = 50g.
Step 2 is to calculate the rate of the IV pump. The maintenance dose is 2g/hr. So, if there are 50g in 1000mL, then 2g would be in (2g ÷ 50g) × 1000mL = 40mL. Therefore, the IV pump should be set at 40 mL/hr.
