A nurse is preparing administer valproic acid 125 mg PO. Available is valproic acid syrup 250 mg/5 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 ["2.5"]
Determine the desired dosage:
The nurse needs to administer 125 mg of valproic acid.
Determine the volume per dose:
The valproic acid syrup contains 250 mg per 5 mL.
The nurse needs to administer 125 mg per dose.
To find the volume per dose:
250 mg / 5 mL = 125 mg / x mL
Cross-multiplying gives us:
250x = 625
Dividing both sides by 250, we get:
x = 2.5 mL

Correct Answer is ["0.75"]
Explanation
Set up the dosage calculation:
Desired dose:60 mg
Available concentration:80 mg/mL
We need to find out how many mL will contain 60 mg of methylprednisolone acetate.
Use the formula:
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Plug in the values and calculate:
Volume (mL) = 60 mg / 80 mg/mL
Volume (mL) = 0.75 mL
Round to the nearest hundredth:
0.75mL
Correct Answer is ["3"]
Explanation
Determine the desired dosage:
The nurse needs to administer 1.5 mg of bumetanide.
Determine the number of tablets per dose:
Each tablet contains 0.5 mg of bumetanide.
The nurse needs to administer 1.5 mg per dose.
To find the number of tablets per dose, we can set up a proportion:
0.5 mg / 1 tablet = 1.5 mg / x tablets
0.5x = 1.5
Dividing both sides by 0.5, we get:
x = 3 tablets
