The healthcare provider prescribed one liter of 0.9% sodium chloride lV Infusion over 6 hours. The IV administration set delivers 10 gtt/mL. The nurse should regulate the drip rate at how many git/minute? (Enter numeric value only. If rounding is required, round to the nearest whole number)
The Correct Answer is ["28"]
Given:
Volume of fluid: 1 liter = 1000 mL
Infusion time: 6 hours
Drop factor: 10 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr
Step 1: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Infusion rate (mL/hr) = 1000 mL / 6 hr
Infusion rate (mL/hr) = 166.67 mL/hr
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr
Flow rate (gtt/min) = (166.67 mL/hr x 10 gtt/mL) / 60 min/hr
Flow rate (gtt/min) = 1666.7 gtt/hr / 60 min/hr
Flow rate (gtt/min) = 27.778 gtt/min
Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 28 gtt/min

Correct Answer is ["7680"]
Explanation
Given:
Ordered loading dose of Heparin: 80 units/kg
Patient weight: 96 kg
Step 1: Calculate the total loading dose of Heparin:
Total loading dose (units) = Ordered dose (units/kg) x Patient weight (kg)
Total loading dose (units) = 80 units/kg x 96 kg
Total loading dose (units) = 7680 units
Correct Answer is ["400"]
Explanation
Given:
Vial strength: Cefazolin 1 gram (1000 mg)
Volume of diluent: 2 mL sterile water
Total volume after reconstitution: 2.5 mL
Step 1: Calculate the concentration of Cefazolin in the reconstituted solution:
Concentration (mg/mL) = Total amount of Cefazolin (mg) / Total volume of solution (mL)
Concentration (mg/mL) = 1000 mg / 2.5 mL
Concentration (mg/mL) = 400 mg/mL
