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.)
Answer and Explanation

The Correct Answer is ["300"]

  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 ["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

First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:

Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg

Now we can calculate the volume (mL) required for the dose:

Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution

Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.
