A client who severed a finger with saw receives a prescription for ketorolac 60 mg IV over 15 minutes. A secondary infusion bag of 0.9% sodium chloride 50 mL with ketorolac 60 mg is provided. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only.)
The Correct Answer is ["200"]
Given:
Volume of fluid: 50 mL
Infusion time: 15 minutes
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Convert infusion time from minutes to hours:
Infusion time (hr) = 15 minutes / 60 minutes/hr
Infusion time (hr) = 0.25 hour
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 50 mL / 0.25 hr
Flow rate (mL/hr) = 200 mL/hr

Correct Answer is ["0.5"]
Explanation
Given:
Ordered dose of interferon beta-1b: 0.125 mg
Vial strength: 0.3 mg
Reconstitution volume: 1.2 mL
Step 1: Determine the concentration of the reconstituted solution:
Concentration (mg/mL) = Total amount of medication (mg) / Volume of solution (mL)
Concentration (mg/mL) = 0.3 mg / 1.2 mL
Concentration (mg/mL) = 0.25 mg/mL
Step 2: Calculate the volume to be administered:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume (mL) = 0.125 mg / 0.25 mg/mL
Volume (mL) = 0.5 mL
Correct Answer is ["40"]
Explanation
Given:
Vial strength: Cefotaxime 2 grams (2000 mg)
Volume of diluent: 50 mL of normal saline
Step 1: Calculate the concentration of Cefotaxime in the reconstituted solution:
Concentration (mg/mL) = Total amount of Cefotaxime (mg) / Total volume of solution (mL)
Concentration (mg/mL) = 2000 mg / 50 mL
Concentration (mg/mL) = 40 mg/mL
