A nurse is preparing to administer lactated Ringer's 75 mL/hr by continuous IV infusion. The drop factor on the manual IV tubing is 20 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.)
The Correct Answer is ["25"]
To calculate the IV flow rate in gtt/min, you need to multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60 min/hr. In this case, the formula is (75 mL/hr x 20 gtt/mL) / 60 min/hr = 25 gtt/min. Therefore, the nurse should set the IV flow rate to deliver 25 gtt/min.

Correct Answer is ["30"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr = (30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.
Correct Answer is ["200"]
Explanation
To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hr) = 50 mL / 0.25 hr
Infusion rate (mL/hr) = 200 mL/hr
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.
