A nurse is preparing to administer levothyroxine 0.4 mg IV bolus. The nurse reconstitutes a vial of levothyroxine to yield a final concentration of 100 mcg/ml. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it apples. Do not use a trailing zero.)
The Correct Answer is ["4"]
The nurse should administer 4 mL of levothyroxine.
Calculations:
Convert 0.4 mg to mcg: 0.4 mg x 1000 mcg/mg = 400 mcg
Desired dose = 400 mcg
Concentration = 100 mcg/mL
Volume = Desired dose / Concentration = 400 mcg / 100 mcg/mL = 4 mL

Correct Answer is ["0.5"]
Explanation
Calculation:
Desired dose = 50 mg
Concentration = 100 mg/mL
Volume = Desired dose / Concentration = 50 mg / 100 mg/mL = 0.5 Ml
Correct Answer is ["9.5"]
Explanation
We need to administer 475 mg of daptomycin.
The reconstituted solution has a concentration of 0.5 g/10 mL, which is equivalent to 50 mg/mL.
Calculation:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 475 mg / 50 mg/mL = 9.5 mL
Therefore, the nurse should administer 9.5 mL of the reconstituted daptomycin solution.
