Coumadin 75 mg is ordered for a patient with deep vein thrombosis. Coumadin 25 mg oral tablets are available in the electronic medication administration record.
How many tablets should the nurse administer to the patient?
1 tablet
2 tablets
3 tablets
4 tablets
4 tablets
The Correct Answer is C
The correct answer is choice C, 3 tablets. To calculate the number of tablets, divide the ordered dose by the available dose:
75 mg ÷ 25 mg = 3
The nurse should administer 3 tablets of Coumadin 25 mg to the patient to give a total dose of 75 mg.

Correct Answer is A
Explanation
The infusion was started at 06:57 and completed at 15:45, which is a total time of: 15 hours and 45 minutes - 6 hours and 57 minutes = 8 hours and 48 minutes
To calculate the flow rate, we need to know the total amount of fluid infused and divide it by the total time of infusion:
1 L = 1000 mL
Total time of infusion = 8 hours and 48 minutes = 528 minutes Flow rate = Total amount of fluid infused / Total time of infusion Flow rate = 1000 mL / 528 minutes
Flow rate = 1.89394 mL/min
To convert mL/min to mL/hr, we multiply by 60:
Flow rate = 1.89394 mL/min x 60 min/hr Flow rate = 113.6364 mL/hr
Therefore, the flow rate of infusion in this situation is approximately 114 mL/hr, which corresponds to option A.
Correct Answer is B
Explanation
To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.
30 lb / 2.205 = 13.61 kg.
Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.
Dose (in mcg) = 136.1 mcg.
Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.
1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.
Cross-multiplying, we get:. 1X = 136.1 x 1.
X = 136.1 mL.
Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
