A nurse is preparing to administer ziprasidone 175 mg IM to a patient. Available is ziprasidone 20 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8.8"]
Step 1: The dose to be administered is175 mg of ziprasidone.
