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 ["167"]

Explanation

To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)

Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr

Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.

Correct Answer is ["0.71"]

Explanation

To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.

The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.

The desired dose is 250 mg.

So, you can use the following formula:

Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)

Volume to administer (mL) = 250 mg / 350 mg/mL

Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)

Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.
