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.)
Answer and Explanation

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 ["300"]

Explanation

  1. Convert tablespoons to milliliters:

    • 1 tablespoon (Tbsp) = 15 mL

  2. Determine the concentration of guaifenesin:

    • The concentration is 100 mg per 5 mL

  3. 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

So, the client is taking 300 mg of guaifenesin with each dose.

Correct Answer is ["2"]

Explanation

To determine how many tablets of sotalol the nurse should administer with each dose, you can use the following calculation:

Total daily dose / Number of doses per day = Dose per administration

In this case, the total daily dose is 320 mg, and it's divided into two doses per day.

320 mg / 2 doses = 160 mg per administration

Now, you know that the nurse should administer 160 mg of sotalol with each dose. The available tablets are 80 mg each, so you can calculate how many tablets are needed:

Dose per administration / Tablet strength = Number of tablets

160 mg / 80 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of sotalol with each dose.
