A nurse is preparing to administer amiodarone 300 mg IV bolus over 10 min to a client. Available is amiodarone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["6"]
To calculate the volume (mL) needed to administer 300 mg of amiodarone using a concentration of 50 mg/mL, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 300 mg, and the concentration is 50 mg/mL:
Volume (mL) = 300 mg / 50 mg/mL = 6 mL
So, the nurse should administer 6 mL of amiodarone.

Convert tablespoons to milliliters:
- 1 tablespoon (Tbsp) = 15 mL
-
Determine the concentration of guaifenesin:
- The concentration is 100 mg per 5 mL
-
Calculate the amount of guaifenesin per 1 tablespoon (15 mL):
- First, find out how many milligrams are in 1 mL:
- 100 mg / 5 mL = 20 mg/mL
- Then, multiply by 15 mL:
- 20 mg/mL × 15 mL = 300 mg
- First, find out how many milligrams are in 1 mL:
So, the client is taking 300 mg of guaifenesin with each dose.
Correct Answer is ["4.5"]
Explanation
To calculate the mL of ondansetron to administer, follow these steps:
Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 132 lb / 2.2 ≈ 60 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 60 kg × 0.15 mg/kg = 9 mg
Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 2 mg / 1 mL = 2 mg/mL
Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 9 mg / 2 mg/mL = 4.5 mL
Round the answer to the nearest tenth:
The nurse should administer 4.5 mL of ondansetron.
