A nurse is preparing to administer 0.9% sodium chloride 1,000 mL IV to infuse over 4 hr. The drop factor on the manual tubing is 12 gtt/mL. The nurse should regulate the 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 ["50"]
To calculate the flow rate in drops per minute (gtt/min), you can use the formula:
Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours
Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes
Then
Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min
Flow rate (gtt/min) = 12000 gtt ÷ 240 min
Flow rate (gtt/min) = 50 gtt/min
Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.

Correct Answer is ["1"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (50 mcg / 0.05 mg) x 1 mL = 1 mL. Round to the nearest whole number: 1 mL.
Correct Answer is ["3.5"]
Explanation
-
Convert the client's weight from pounds to kilograms:
- 154 lb ÷ 2.2 lb/kg = 70 kg
-
Calculate the total dose required:
- 0.25 mg/kg × 70 kg = 17.5 mg
-
Determine the volume to administer:
- Given concentration: 5 mg/mL
- 17.5 mg ÷ 5 mg/mL = 3.5 mL
-
Rounding to the nearest tenth:
- The answer remains 3.5 mL
So the nurse should administer 3.5 mL of diltiazem IV injection.
which is 17.5 mg / 5 mg/mL = 3.5 mL. Rounding to the nearest tenth, the nurse should administer 3.5 mL of diltiazem IV injection.
