The nurse is preparing change of shift report for a client who has an IV infusion of 1000 mL of 0.9% sodium chloride. The infusion was started 5 hours ago at a rate of 125 mL/hour via an infusion pump. The nurse should report how many mL remain to be infused to the oncoming nurse? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["375"]
Given:
Total volume of infusion: 1000 mL
Infusion rate: 125 mL/hour
Infusion started 5 hours ago
Step 1: Calculate the volume infused in 5 hours:
Volume infused = Infusion rate (mL/hour) x Time (hours)
Volume infused = 125 mL/hour x 5 hours
Volume infused = 625 mL
Step 2: Calculate the remaining volume:
Remaining volume = Total volume - Volume infused
Remaining volume = 1000 mL - 625 mL
Remaining volume = 375 mL

Correct Answer is ["1.5"]
Explanation
Given:
Ordered dose of Midazolam: 3 mg SUBQ every 2 hours PRN
Concentration of Midazolam: 2 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
3 mg / Volume = 2 mg/mL
Step 3: Solve for the unknown volume:
Volume = 3 mg / (2 mg/mL)
Volume = 3 mg x (1 mL / 2 mg)
Volume = 1.5 mL
Correct Answer is ["30"]
Explanation
Given:
Total insulin in solution: 100 units
Volume of solution: 250 mL
Infusion rate: 12 units/hour
Step 1: Determine the concentration of insulin in the solution:
Concentration (units/mL) = Total insulin (units) / Volume of solution (mL)
Concentration (units/mL) = 100 units / 250 mL
Concentration (units/mL) = 0.4 units/mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Infusion rate (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 12 units/hr / 0.4 units/mL
Infusion rate (mL/hr) = 30 mL/hr
