A nurse is preparing to administer metoclopramide 15 mg PO QID before meals and at bedtime for a client who has GERD. The amount available is metoclopramide 5 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.)
The Correct Answer is ["15"]
Rationale:
Desired dose = 15 mg
Available concentration = 5 mg per 5 mL = 1 mg/mL
Volume needed = Desired dose ÷ Concentration = 15 mg ÷ 1 mg/mL = 15 mL
Rounded to nearest whole number = 15 mL
Final Answer: 15 mL
