(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["26"]
1.7mg/min = 1.7*60 = 102mg/hr 1g=1000mg
1000mg= 250mls of lidocaine dextrose 102mg = 102*250/1000 = 25.5ml/hr
Rounded off to the nearest whole number, the pump should be set deliver 26 mL/hr.

Correct Answer is ["10"]
Explanation
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 ["0.25"]
Explanation
volume = 0.5 mg / (1 mg/0.5 mL) volume = 0.5 mg x 0.5 mL / 1 mg volume = 0.25 mL
