Calculation
A nurse is preparing to administer erythromycin ethylsuccinate 800 mg PO every 4 hr. Available is erythromycin ethylsuccinate 200 mg/5mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Step 1 is: Calculate the amount of erythromycin ethylsuccinate needed. 800 mg ÷ (200 mg ÷ 5 mL) = 800 mg ÷ 40 mg/mL = 20 mL. The nurse should administer 20 mL.
