Question

Order: levothyroxine 200mcg IV bolus Reconstitution: 100mcg/mL How many mL should the nurse administer?

Answer 1

Answer:

2 milliliters (2 mL)

Explanation:

In order to solve for the dosage amount, multiply the ordered dose as written by the provider by the dosage strength indicated by the given reconstitution conversion:

(ordered dose mcg) x (reconstitution mL / mcg)

Now substituting the written information, this expression becomes:

$200 mcg(\frac{1 mL}{100 mcg} )$ or 200 mcg x (1 mL/100 mcg)

Micrograms (mcg) in both numerator and denominator will cancel each other out, leaving milliliters (mL) as the unit of measurement. Now we perform multiplication like usual:

200 x $\frac{1}{100}$
200(1) / 100
200 / 100
2

The nurse should administer 2 milliliters (2 mL) of levothyroxine IV bolus.
