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

Correct Answer is ["1.5"]
Explanation
Understanding the Problem
Order: Midazolam 0.03 mg/kg IM
Client Weight: 110 lbs
Available Solution: Midazolam 1 mg/mL
Desired Dose: mL to administer
Step 1: Convert Client Weight to Kilograms (kg)
1 kg = 2.2 lbs
Client Weight in kg: 110 lbs / 2.2 lbs/kg = 50 kg
Step 2: Calculate the Total Dose
Ordered Dose: 0.03 mg/kg
Client Weight: 50 kg
Total Dose: 0.03 mg/kg x 50 kg = 1.5 mg
Step 3: Calculate the Volume to Administer
Total Dose: 1.5 mg
Concentration: 1 mg/mL
Volume: 1.5 mg / 1 mg/mL = 1.5 mL
Step 4: Round to the Nearest Tenth
The calculated volume is 1.5 mL, which is already to the nearest tenth.
Answer: 1.5 mL
Correct Answer is ["0.3"]
Explanation
Calculate the Total Daily Dose:
Dose: 40 mg/kg/day
Weight: 5 kg
Total Daily Dose: 40 mg/kg/day x 5 kg = 200 mg/day
Calculate the Dose Per Administration:
The dose is divided equally every 12 hours, meaning twice a day.
Dose Per Administration: 200 mg/day / 2 doses/day = 100 mg/dose
Calculate the Volume to Administer:
Available Concentration: 330 mg/mL
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Volume (mL) = 100 mg / 330 mg/mL
Volume (mL) ≈ 0.303 mL
Round to the Nearest Tenth:
0.3 mL
