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 ["4"]
Explanation
Ordered dose of tetracycline: 500 mg every 12 hours
Available tetracycline capsules: 250 mg/capsule
Step 1: Determine the total daily dose of tetracycline:
Since the medication is given every 12 hours, there are 2 administrations per day.
Total daily dose (mg) = Dose per administration (mg) x Number of administrations per day
Total daily dose (mg) = 500 mg/dose x 2 doses/day
Total daily dose (mg) = 1000 mg/day
Step 2: Calculate the number of capsules required per day:
Number of capsules/day = Total daily dose (mg) / Strength of each capsule (mg/capsule)
Number of capsules/day = 1000 mg/day / 250 mg/capsule
Number of capsules/day = 4 capsules/day
Correct Answer is ["0.4"]
Explanation
Given:
Ordered dose of methylprednisolone succinate: 1.5 mg/kg/day IV in divided doses every 6 hours
Child's weight: 42 kg
Concentration of methylprednisolone succinate: 40 mg/mL
Step 1: Calculate the total daily dose of methylprednisolone succinate:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Child's weight (kg)
Total daily dose (mg) = 1.5 mg/kg/day x 42 kg
Total daily dose (mg) = 63 mg/day
Step 2: Calculate the dose per administration:
Since the medication is given every 6 hours, there are 4 administrations per day.
Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day
Dose per administration (mg) = 63 mg/day / 4 administrations/day
Dose per administration (mg) = 15.75 mg
Step 3: Calculate the volume to be administered per dose:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)
Volume (mL) = 15.75 mg / 40 mg/mL
Volume (mL) = 0.39375 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 0.4 mL
