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

Explanation
Desired dose of magnesium sulfate: 2 g/hr
Concentration of magnesium sulfate solution: 40 g in 1,000 mL
Step 1: Calculate the desired volume of magnesium sulfate per hour:
Volume of magnesium sulfate per hour = Desired dose (g/hr) / Concentration (g/mL)
Volume of magnesium sulfate per hour = 2 g/hr / (40 g / 1,000 mL)
Volume of magnesium sulfate per hour = 2 g/hr / 0.04 g/mL
Volume of magnesium sulfate per hour = 50 mL/hr
