The order from a provider is: Administer Penicillin 3 gm IV on call to OR over 1 hour. The pharmacy provides Penicillin 3 gm diluted in 150 mL of NS. The drop factor is 10 gtt/mL. What is the gtt/min

Answer and Explanation

The Correct Answer is ["25"]

Total Penicillin dose: 3 gm (as given in the order)

Available volume: The pharmacy provides 150 mL of NS with the Penicillin already diluted.

Infusion time: 1 hour.

Rate (mL/min) = Total volume (mL) / Total time (minutes)

1 hour = 60 minutes

Rate (mL/min) = 150 mL / 60 minutes = 2.5 mL/min

Drop factor: The drip factor is 10 gtt/mL, meaning 10 drops deliver 1 mL of solution. Rate (gtt/min): To find the rate in gtt/min, multiply the rate (mL/min) by the drip factor (gtt/mL).

Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)

Rate (gtt/min) = 2.5 mL/min x 10 gtt/mL = 25 gtt/min

Correct Answer is ["56"]

Explanation

To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL x Drip factor) / Time in minutes. In this case, the nurse has 500 mL of Ringer's lactate to infuse over 3 hours. First, convert the hours into minutes: 3 hours x 60 minutes/hour = 180 minutes. Next, multiply the volume by the drip factor: 500 mL x 20 gtt/mL = 10,000 gtt. Finally, divide by the total time in minutes: 10,000 gtt / 180 minutes = approximately 55.56 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver around 56 gtt/min.

Correct Answer is ["12"]

Explanation

To calculate the rate for the infusion pump, you need to determine how many milliliters per hour (mL/hr) will deliver 1200 units of heparin. First, find the concentration of the heparin solution by dividing the total units of heparin by the total volume of the solution. In this case, 25,000 units divided by 250 mL equals 100 units/mL. Next, divide the ordered amount of heparin units per hour by the concentration to find the rate in mL/hr. So, 1200 units per hour divided by 100 units/mL equals 12 mL/hr.
