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.

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.

Correct Answer is ["100"]
Explanation
The nurse should set the IV flow rate to deliver 100 gtt/min.
To calculate the flow rate in gtt/min, you can use the formula: (Volume to be infused (mL) x Drop factor (gtt/mL)) ÷ Time (min) = Flow rate (gtt/min).
Plugging in the values from the question: (100 mL x 60 gtt/mL) ÷ 60 min = 100 gtt/min.
