A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily.
The amount available is digoxin 0.125 mg tablet.
How many tablets should the nurse administer per dose? (Round to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.).
1.
2.
3.
4.
The Correct Answer is B
To calculate the number of tablets the nurse should administer per dose, you need to divide the prescribed dose of digoxin (0.25 mg) by the amount of digoxin available in each tablet (0.125 mg/tablet).
This gives you a result of 0.25 mg / 0.125 mg/tablet = 2 tablets.
Choice A: 1 is not the answer because 0.25 mg / 0.125 mg/tablet = 2 tablets.
Choice C: 3 is not the answer because 0.25 mg / 0.125 mg/tablet = 2 tablets.
Choice D: 4 is not the answer because 0.25 mg / 0.125 mg/tablet = 2 tablets.

Explanation
To calculate the flow rate in gtt/min, you need to divide the total volume of the IV fluid (400 mL) by the total infusion time in minutes (8 hours x 60 minutes/hour = 480 minutes) and then multiply by the drop factor of the manual IV tubing (60 gtt/mL).
This gives you a flow rate of (400 mL / 480 minutes) x 60 gtt/mL = 50 gtt/min.
