1 mL.
A patient spikes a brief rise in blood pressure and heart rate during laryngoscopy. You want to give 50 mcg of Fentanyl. How much of your syringe will you administer?
1 mL (since the concentration is 50 mcg/mL).
To blunt the burning sensation from Propofol, you decide to give Lidocaine first. You administer 40 mg of Lidocaine. How many mL is that from your syringe?
4 mL (10 mg/mL concentration).
You’re inducing a healthy adult patient and plan to give 2 mg/kg of Propofol. The patient weighs 70 kg. How much total volume will you give from your 10 mg/mL syringe?
14 mL (140 mg total dose ÷ 10 mg/mL).
For intubation, you’re giving 0.6 mg/kg of Rocuronium to a 70 kg patient. How much volume will you administer from your 10 mg/mL syringe?
4.2 mL (42 mg dose ÷ 10 mg/mL).
A patient requires RSI and you’re giving 1 mg/kg of Succinylcholine. The patient weighs 80 kg. How many mL will you draw up from your 20 mg/mL syringe?
4 mL (80 mg dose ÷ 20 mg/mL).
Your patient becomes hypotensive with a BP of 78/40. You plan to give a 100 mcg bolus of Phenylephrine. How much of your 100 mcg/mL syringe will you give?
1 mL.
During spinal anesthesia, your patient’s BP drops and you decide to give 10 mg of Ephedrine. What volume will you administer from your 10 mg/mL syringe?
1 mL.
You want to reverse neuromuscular blockade and pair Glycopyrrolate with Neostigmine. You decide to give 0.2 mg of Glycopyrrolate. How much volume is that from your 0.2 mg/mL syringe?
1 mL.
How many mL of Propofol will you draw up for a 90 kg adult?
Propofol: 2 mg/kg × 90 kg = 180 mg → 180 mg ÷ 10 mg/mL = 18 mL
Which drug requires more volume from your syringe: Rocuronium or Succinylcholine for a 75 kg patient?
Rocuronium: 1.2 mg/kg × 75 kg = 90 mg → 90 mg ÷ 10 mg/mL = 9 mL
Succinylcholine: 1.5 mg/kg × 75 kg = 112.5 mg → 112.5 mg ÷ 20 mg/mL = 5.6 mL
Answer: Rocuronium requires more volume (9 mL vs. 5.6 mL)
How long will a Phenylephrine syringe last at a rate of 40 mcg/min?
1000 mcg ÷ 40 mcg/min = 25 minutes
You gave your patient 100 mcg of Fentanyl at induction. Forty minutes into the case, vitals indicate sympathetic stimulation (↑HR, ↑BP). You decide to redose with 1 mcg/kg. The patient weighs 65 kg.
• How much Fentanyl will you give in mL?
• Dose: 65 mcg
• Volume: 65 mcg ÷ 50 mcg/mL = 1.3 mL

• How much volume do you administer?
• Dose: 50 mg
• Volume: 50 mg ÷ 20 mg/mL = 2.5 mL
Two patients need intubation.
• Patient A: 60 kg
• Patient B: 100 kg
You’re dosing Rocuronium at 1 mg/kg.
• How much total Rocuronium will you need in mg and mL for both?
• Patient A: 60 mg = 6 mL
• Patient B: 100 mg = 10 mL
• Total: 160 mg = 16 mL
You’re treating intermittent hypotension with 50 mcg boluses of Phenylephrine.
• Your syringe has 1000 mcg in 10 mL.
• How many doses can you draw?
• How many mL is each dose?
• Each dose: 50 mcg ÷ 100 mcg/mL = 0.5 mL
• Total doses: 10 mL ÷ 0.5 mL = 20 doses
You’re handed a 50 mL vial of Propofol. You want to prepare a syringe containing 200 mg.
• How much volume will you draw up?
• 200 mg ÷ 10 mg/mL = 20 mL
A student accidentally gives 2 mL of Ephedrine from a 10 mg/mL syringe.
• How much was given?
• 2 mL × 10 mg/mL = 20 mg
