A nurse is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets 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 ["2"]
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 0.25 mg = 1 tablet / 0.125 mg
Cross-multiplying:
0.125x = 0.25
Solving for x:
x = 0.25 / 0.125
x = 2
Therefore, the nurse should administer 2 tablets of digoxin daily.

Correct Answer is ["8"]
Explanation
To calculate the volume of valproic acid to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 400 mg / (250 mg/5 mL)
Volume (mL) = 400 mg x (5 mL / 250 mg)
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of valproic acid per dose.
Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 650 mg = 1 tablet / 325 mg
Cross-multiplying:
325x = 650
Solving for x:
x = 650 / 325
x = 2
Therefore, the nurse should administer 2 tablets of aspirin per dose.
