Question 3 of 5
The primary health care provider prescribes 650 mg of an antibiotic to be administered intravenously every 6 hours. The medication label reads as follows: reconstitute with 4.8 mL of bacteriostatic water to yield 2 g in 5 mL. How many mL should the nurse withdraw from the vial for 1 dose? Fill in the blank. Record the answer using 1 decimal place.
Correct Answer: 1.6 mL
Rationale: Convert 2 g to mg and then use the formula for calculating medication doses. In the metric system, to convert larger to smaller, multiply by 1000 or move the decimal 3 places to the right.
Therefore, 2 g = 2000 mg. Formula: Desired / Available x Available Volume = 650 mg / 2000 mg x 5 mL = 1.625 mL = 1.6 mL.

When desmopressin acetate is prescribed via intranasal route for a child diagnosed with von Willebrand's disease, the nurse instructs the parents regarding the administration of this medication. Which statement by the parents indicates a need for further teaching?

The medication should be refrigerated, but freezing should be avoided.
