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 ["0.5"]
Explanation
To calculate the volume of vitamin K to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 1 mg / 1 mg/mL
Volume (mL) = 1 mL
However, the medication is available in a 0.5 mL vial containing 1 mg of vitamin K. This means that the entire 0.5 mL vial contains the desired dose of 1 mg.
Therefore, the nurse should administer 0.5 mL of vitamin K.
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.
