Order: ceftriaxone 2 g in 100 mL of 0.9% NaCI (normal saline solution) over 30 minutes
Available: Macro drip set: 15 gtt/mL
Calculate the IV flow rate in gtt/min.
50 gtt/min
15 gtt/min
10 gtt/min
100 gtt/min
The Correct Answer is A
1. Determine the total volume to be infused: 100 mL
2. Calculate the infusion time in minutes: 30 minutes
3. Calculate the drip rate (gtt/min):
Drip rate = (Total volume / Infusion time) x Drop factor
Drip rate = (100 mL / 30 minutes) x 15 gtt/mL
Drip rate = 50 gtt/min
Therefore, the correct answer is 50 gtt/min

Correct Answer is D
Explanation
Ordered dose of 0.9% Sodium Chloride: 20 mL/kg
Child's weight: 55 lbs
Infusion time: 6 hours
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg
Step 2: Calculate the total volume of 0.9% Sodium Chloride:
Total volume (mL) = Ordered dose (mL/kg) x Child's weight (kg)
Total volume (mL) = 20 mL/kg x 24.94756 kg
Total volume (mL) = 498.9512 mL
Step 3: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Infusion rate (mL/hr) = 498.9512 mL / 6 hr
Infusion rate (mL/hr) = 83.15853333 mL/hr
Step 4: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 83 mL/hr
Correct Answer is A
Explanation
Given:
Value in grams: 5,524 g
To convert grams to kilograms, we need to divide the value by 1000.
Step 1: Divide the value by 1000:
5,524 g / 1000 = 5.524 kg
