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 ["3"]

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

Correct Answer is ["60"]

Explanation

To calculate the IV flow rate in gtt/min, you can use the following formula:

Flow rate (gtt/min) = (Volume to be infused (mL) x Drop factor) / Time (min)

In this case, the volume to be infused is 60 mL/hr, the drop factor is 60 gtt/mL, and we want to find the flow rate in gtt/min.

Flow rate (gtt/min) = (60 mL/hr x 60 gtt/mL) / 60 min

Flow rate (gtt/min) = (3600 gtt/hr) / 60 min

Flow rate (gtt/min) = 60 gtt/min
