A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual V tubing is 10 gtt/ml. The nurse should set the manual IV flow rate to deliver how many gtt/min? (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 ["83"]

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

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

Given:

  • Volume to be infused = 250 mL
  • Time in minutes = 30 minutes
  • Drop factor = 10 gtt/mL

Now, plug these values into the formula:

Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL

Flow rate (gtt/min) = (8.33) * 10

Flow rate (gtt/min) ≈ 83.3

Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.

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 ["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
