A nurse is preparing to administer docusate sodium PO to a postpartum client who has a prescription for 200 mg/day in two equally divided doses. The client states she has trouble swallowing tablets and capsules. Therefore, the nurse has obtained docusate sodium liquid 50 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies)
The Correct Answer is ["10"]
The question is asking for the amount of docusate sodium liquid the nurse should administer per dose. The prescription is for 200 mg/day in two equally divided doses, and the liquid form of the medication is 50 mg/5 mL.
Step 1 is to determine the amount of medication needed per dose. Since the total daily dose is 200 mg and it’s divided into two doses, each dose will be 200 mg ÷ 2 = 100 mg.
Step 2 is to convert this dose from mg to mL using the concentration of the liquid medication. The concentration is 50 mg/5 mL, which means that 1 mL contains 50 mg ÷ 5 = 10 mg of the medication.
Step 3 is to calculate the volume of the medication needed for a 100 mg dose. Since 1 mL contains 10 mg, we need 100 mg ÷ 10 mg/mL = 10 mL.
So, the nurse should administer 10 mL of docusate sodium liquid per dose.

Explanation
To calculate the number of tablets to administer, you need to divide the prescribed dose by the available dose. In this case, the prescribed dose is 0.25 mg and the available dose is 0.125 mg. Therefore, the number of tablets is:
0.25 mg / 0.125 mg = 2 tablets
The nurse should administer 2 tablets of digoxin 0.125 mg to the client.
Correct Answer is ["167"]
Explanation
To find the infusion rate in mL/hr, divide the total volume of fluid by the total time of infusion.
Total volume of fluid = 1,000 mL Total time of infusion = 6 hr
Infusion rate = 1,000 mL / 6 hr = 166.67 mL/hr
Round the answer to the nearest whole number: 167 mL/hr
