A nurse is preparing to administer lactated Ringer's IV to infuse at 60 mL/hr. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the 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.)

Full 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

A nurse is preparing to administer ceftriaxone 250 mg IM to an adult client who has a gonococcal infection. The label on the vial indicates to reconstitute each vial with sterile water 2.1 mL to yield ceftriaxone 350 mg/mL. How many mL of the reconstituted medication should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Full 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.
A nurse is preparing to administer clindamycin 1,200 mg IV bolus over 1 hr to a client who is allergic to penicillin. Available is clindamycin 1,200 mg in dextrose 5% in water 100 mL. The drop factor on the manual IV tubing is 15 gtt/mL. The nurse should set the 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.)
Full 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.
A nurse is preparing to administer penicillin G potassium 1,000,000 units intermittent IV bolus. The label on the vial indicates to reconstitute with 50 ml of sterile water to make penicillin G potassium 100,000 units/ml. How many ml, should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
To determine how many milliliters (mL) of the reconstituted penicillin G potassium to administer, you can use the following calculation:
Given:
- Reconstituted concentration: 100,000 units/mL
- Total dose to be administered: 1,000,000 units
Now, use the formula:
Volume (mL) = Total dose (units) / Concentration (units/mL)
Volume (mL) = 1,000,000 units / 100,000 units/mL
Volume (mL) = 10 mL
So, the nurse should administer 10 mL of the reconstituted penicillin G potassium.
