A nurse is preparing to administer 0.9% sodium chloride mL IV to infuse over 4 hr to a client. The drop factor of the manual IV tubing 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many git/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 ["6"]
Calculate the Total Infusion Time in Minutes:
The infusion is to be delivered over 4 hours.
There are 60 minutes in 1 hour.
Total infusion time: 4 hours x 60 minutes/hour = 240 minutes
Calculate the Drip Rate (gtt/min):
We'll use the following formula:
Drip Rate (gtt/min) = (Total Volume (mL) x Drop Factor (gtt/mL)) / Total Infusion Time (minutes)
Plug in the Values and Calculate:
Drip Rate (gtt/min) = (100 mL x 15 gtt/mL) / 240 minutes
Drip Rate (gtt/min) = 1500 gtt / 240 minutes
Drip Rate (gtt/min) = 6.25 gtt/min
Round to the Nearest Whole Number:
6 gtt/min

Explanation
Understanding the Problem
Order: Metoclopramide 15 mg IV
Available Solution: Metoclopramide 5 mg/mL
Desired Dose: mL to administer
Step 1: Set Up the Calculation
We need to find the volume (in mL) that contains the ordered dose (15 mg). We can do this by dividing the ordered dose by the concentration of the available solution:
Volume (mL) = Ordered Dose (mg) / Concentration (mg/mL)
Step 2: Perform the Calculation
Ordered Dose: 15 mg
Concentration: 5 mg/mL
Volume: 15 mg / 5 mg/mL = 3 mL
Step 3: Round to the Nearest Whole Number
The result is 3 mL, which is already a whole number.
Answer: 3 mL
Correct Answer is ["25"]
Explanation
Identify the Given Information:
Infusion Rate: 100 mL/hr
Drop Factor: 15 gtt/mL
Convert the Infusion Rate to mL/min:
There are 60 minutes in 1 hour.
Infusion Rate (mL/min) = 100 mL/hr / 60 min/hr
Infusion Rate (mL/min) = 1.6667 mL/min (approximately)
Calculate the Drip Rate (gtt/min):
Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)
Drip Rate (gtt/min) = 1.6667 mL/min x 15 gtt/mL
Drip Rate (gtt/min) = 25 gtt/min
Round to the Nearest Whole Number (if necessary):
25 gtt/min
