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 ["100"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following formula:
gtt/min = (Volume (mL) x Drop Factor (gtt/mL)) / Time (minutes)
Given:
Volume = 100 mL
Drop Factor = 60 gtt/mL
Time = 1 hour = 60 minutes
Plugging in the values:
gtt/min = (100 mL x 60 gtt/mL) / 60 minutes
Simplifying:
gtt/min = 6000 gtt / 60 minutes
Calculating the result:
gtt/min = 100 gtt/min
Therefore, the nurse should set the IV flow rate to deliver 100 gtt/min.
Correct Answer is ["1.5"]
Explanation
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 150 mg = 1 tablet / 100 mg
Cross-multiplying:
100x = 150
Solving for x:
x = 150 / 100
x = 1.5
Therefore, the nurse should administer 1.5 tablets of desipramine per dose.
