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.

Correct Answer is ["45"]
Explanation
Pump rate in mL/hour = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL)
The concentration of nitroprusside is given as 50 mg in 250 mL of dextrose 5% in water.
Convert this to mcg/mL; multiply by 1000
Concentration (mcg/mL) = 50 mg x 1000 / 250 mL = 200 mcg/mL Therefore;
Pump rate in mL/hour = 2 mcg/kg/min x 75 kg x 60 / 200 mcg/mL Pump rate in mL/hour = 45 mL/hour
Therefore, the nurse should set the IV pump to deliver 45 mL/hour
Correct Answer is ["8"]
Explanation
Number of tablets = (Dose per administration x Number of administrations per day) / Tablet strength
Number of tablets = (500 mg x 4) / 250 mg
Number of tablets = 2000 mg / 250 mg Number of tablets = 8
Therefore, the nursing staff should administer 8 tablets in a 24hrs.
