(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 ["3"]

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 ["25"]

Explanation

To calculate the flow rate in drops per minute (gtt/min) for the IV infusion of clindamycin, you can use the following formula:

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

First, you need to determine the volume to be infused. In this case, it's 100 mL. The drop factor is given as 15 gtt/mL, and the time is 60 minutes (1 hour).

Now, plug these values into the formula:

Flow rate (gtt/min) = (100 mL * 15 gtt/mL) / 60 minutes

Flow rate (gtt/min) = (1500 gtt) / 60 minutes

Flow rate (gtt/min) = 25 gtt/min

So, the nurse should set the flow rate to deliver 25 gtt/min for the IV infusion of clindamycin.

Correct Answer is ["6"]

Explanation

To calculate the volume (mL) needed to administer 300 mg of amiodarone using a concentration of 50 mg/mL, you can use the following formula:

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

In this case, the dose is 300 mg, and the concentration is 50 mg/mL:

Volume (mL) = 300 mg / 50 mg/mL = 6 mL

So, the nurse should administer 6 mL of amiodarone.
