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 ["145"]

Explanation

To calculate the dose of metronidazole for a client who weighs 212 lb, the nurse needs to convert the weight to kilograms and multiply it by the prescribed dose of 7.5 mg/kg.

One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 212/2.2 = 96.36 kg. The dose of metronidazole in milligrams is 96.36 x 7.5 = 722.7 mg.

The nurse needs to find out how many mL of the available solution contain this amount of metronidazole.

The available solution has a concentration of 500 mg/100 mL, so the nurse can use a proportion to solve for the volume: 500/100 = 722.7/x.

Cross-multiplying and solving for x gives x = 722.7 x 100 / 500 = 144.54 mL.

The nurse should round the answer to the nearest whole number, so the final answer is 145 mL.

The nurse should administer 145 mL of metronidazole via intermittent IV bolus to the client.

Correct Answer is ["5"]

Explanation

To calculate the volume of megestrol oral suspension (in milliliters, mL) that the nurse should administer, use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

In this case, the dose is 200 mg of megestrol, and the concentration of the oral suspension is 40 mg/mL.

Volume (mL) = 200 mg / 40 mg/mL

Volume (mL) = 5 mL

The nurse should administer 5 mL of megestrol oral suspension to the client.
