A nurse is assisting with the care of a newborn who has a prescription for nystatin 100,000 units PO four times each day. Available is nystatin suspension 100.000 units/mL. How many mL should the nurse administer per dose? (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 ["1"]
Given:
Desired dose of nystatin: 100,000 units
Concentration of nystatin suspension: 100,000 units/mL
Step 1: Set up the proportion:
Desired dose (units) / Volume to administer (mL) = Concentration (units/mL)
Step 2: Substitute the values:
100,000 units / Volume = 100,000 units/mL
Step 3: Solve for the unknown volume:
Volume = 100,000 units / 100,000 units/mL
Step 4: Calculate the volume:
Volume = 1 mL
