Correct Answer is ["1.3"]
Explanation
Desired dose = 750,000 units
Available concentration = 600,000 units/mL
Volume to administer = Desired dose / Concentration = 750,000 units / 600,000 units/mL = 1.25 mL
Rounded to the nearest tenth = 1.3 mL
Correct Answer is ["4.8"]
Explanation
Understanding the problem
We need to administer 240 mg of hydrocortisone.
The reconstituted solution has a concentration of 50 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume (mL) = 240 mg / 50 mg/mL
Calculate the volume:
Volume (mL) = 4.8 mL
Therefore, the nurse should administer 4.8 mL of the reconstituted hydrocortisone solution.
