A nurse is preparing to administer acetaminophen 15 mg/kg via intermittent IV bolus to a client who weighs 99 lb. The amount available is acetaminophen 1,000 mg/100 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 ["68"]
To calculate the mL of acetaminophen 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 = 99 lb / 2.2 ≈ 45 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 45 kg × 15 mg/kg = 675 mg
Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 1,000 mg / 100 mL = 10 mg/mL
Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 675 mg / 10 mg/mL = 67.5 mL
Round the answer to the nearest whole number:
The nurse should administer 68 mL of acetaminophen

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.
Correct Answer is ["0.71"]
Explanation
To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.
The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.
The desired dose is 250 mg.
So, you can use the following formula:
Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)
Volume to administer (mL) = 250 mg / 350 mg/mL
Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)
Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.
