A nurse is preparing to administer ondansetron 0.15 mg/kg IV to a client who weighs 132 lb. Available is ondansetron 2 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 ["4.5"]
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 ["10"]
Explanation
To calculate the volume in milliliters (mL) of amoxicillin oral suspension needed to administer 775 mg, you can use the following formula:
Volume (mL) = (Desired dose in mg / Concentration in mg/mL)
Given:
- Desired dose = 775 mg
- Concentration = 400 mg/5 mL
First, calculate the concentration in mg/mL by dividing 400 mg by 5 mL:
Concentration = 400 mg / 5 mL = 80 mg/mL
Now, use the formula to calculate the volume in mL:
Volume (mL) = (775 mg / 80 mg/mL)
Volume (mL) ≈ 9.69 mL
Rounded to the nearest whole number, the nurse should administer approximately 10 mL of amoxicillin oral suspension to provide a dose of 775 mg.
Correct Answer is ["1.5"]
Explanation
To calculate the number of tablets to administer, you can use the following calculation:
Number of tablets = Desired dose (mg) / Tablet strength (mg per tablet)
Number of tablets = 15 mg / 10 mg per tablet
Number of tablets = 1.5 tablets
