Question 1 of 5
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?
Correct Answer: 20
Rationale: The correct answer is 20 mL.
To calculate the mL needed, first determine the total daily dose (800 mg every 4 hr = 4800 mg/day).
Then, divide the total daily dose by the concentration of the available solution (200 mg/5mL). This gives us 24 mL/day. Since the medication is given every 4 hours, divide 24 mL by 6 to get the amount needed for each dose, which is 4 mL.
Therefore, the nurse should administer 4 mL every 4 hours, totaling 20 mL in a 24-hour period. Other choices are incorrect because they do not follow the correct calculation method or steps.
