A nurse is preparing to administer ketorolac 12 mg IV bolus to an adolescent. The amount available is ketorolac injection 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
Step by step calculation:
The desired dose of ketorolac is 12 mg.
The available concentration is 15 mg/mL.
Calculating the volume to administer:
Use the concentration of the medication: 12 mg ÷ 15 mg/mL = 0.8 mL

Correct Answer is ["0.24"]
Explanation
Step 1: Convert the infant's weight from pounds to kilograms.
To convert pounds to kilograms, we use the conversion factor 1 kg = 2.2 lb.
Weight in kg= 21/2.2≈9.55 kg
Step 2: Calculate the total daily dose of clindamycin in mg.
Total dose in mg/day=15 mg/kg/day×9.55 kg=143.25 mg/day
Step 3: Divide the total daily dose into 4 equal doses (every 6 hours).
We divide the total daily dose by 4:
Dose per administration=143.25 mg/4=35.8125 mg/dose
Step 4: Determine the volume to administer per dose.
The available clindamycin phosphate injection concentration is 150 mg/mL. To determine how many mL the nurse should administer per dose, we use the following formula:
Volume (mL)=Dose in mg/Concentration in mg/mL=35.8125 mg/150 mg/mL=0.238 mL
Step 5: Round the answer.
Rounding off 0.238 mL gives 0.24 mL.
Correct Answer is ["83"]
Explanation
Flow rate (mL/hr)=Total volume (mL)/Infusion time (hr)
Insert the given values:
Total volume = 1,000 mL.
Infusion time = 12 hr.
Flow rate=1,000 mL/12 hr=83.33 mL/hr
Round to the nearest whole number:
83.333 rounds to 83 mL/hr
