Question 1 of 45 :
A nurse is preparing to administer amantadine 75 mg PO every 12 hr. Available is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose? (Do not use a leading zero, Round the answer to the tenth place, Do not use a trailing zero.)
Correct Answer: 7.5
Available concentration (mg)/Desired dose (mg)=Available volume (mL)/Required volume (mL)
Plugging in the values:
50 mg75 mg=5 mLx mL
To solve for x, we can multiply both sides by 5 mL:
x mL=5075×5 mL
x mL=1.5×5 mL
x mL=7.5 mL
Therefore, the nurse should administer 7.5 mL per dose.
