Full 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.

QUESTION

A nurse is caring for a client who reports taking 1 Tbsp of guaifenesin oral solution every 4 hr. The concentration on the client's bottle reads guaifenesin 100 mg/5 mL. How many mg of guaifenesin is the client taking with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Full Explanation

To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
    Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
    1 Tbsp is approximately equal to 15 mL.
    Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
    Calculate the amount of guaifenesin in the client's dose:
    Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
    Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.

QUESTION

A nurse is preparing to administer pyrazinamide 20 mg/kg PO to a client who weighs 165 lb and has tuberculosis. Available is pyrazinamide 500 mg tablets. How many tablets 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.)

Full Explanation

To calculate how many tablets of pyrazinamide the nurse should administer, you can use the following 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 = 165 lb / 2.2 ≈ 75 kg
    
    Determine the total dosage required based on the client's weight:
   Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 75 kg × 20 mg/kg = 1500 mg
    
    Determine the number of tablets needed:
    Number of tablets = Total dosage / Tablet strength Number of tablets = 1500 mg / 500 mg/tablet = 3 tablets
    
The nurse should administer 3 tablets of pyrazinamide

QUESTION

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.)

Full Explanation

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
