Question 4

c. A physician orders 2g of an antibiotic to be placed in 1000ml of D5W. Using an injection that contains 300mg of the antibiotic per 2ml, how many milliliters should be added to the dextrose injection in preparing the medication order? (2 marks)

Convert the ordered dose from grams to milligrams.
$\text{Ordered dose} = 2\text{ g} \times 1000\frac{\text{ mg}}{\text{g}} = 2000\text{ mg}$
Determine the concentration of the antibiotic injection.
$\text{Concentration} = \frac{300\text{ mg}}{2\text{ mL}} = 150\frac{\text{ mg}}{\text{mL}}$
Calculate the volume needed for the ordered dose.
$\text{Volume} = \frac{\text{Ordered dose}}{\text{Concentration}}$ $\text{Volume} = \frac{2000\text{ mg}}{150\frac{\text{ mg}}{\text{mL}}} \approx 13.33\text{ mL}$
$\boxed{\textbf{13.33 mL}}$ of the antibiotic injection should be added.
