Question 1 of 5
What is the term for removing air from the IV tubing?
Correct Answer: B
Rationale: Priming the IV tubing removes air to prevent air embolism during infusion.
Question 2 of 5
Name four of the most commonly used veins for IV initiation.
Correct Answer: B
Rationale: Cephalic, basilic, median cubital, and dorsal hand veins are large, accessible, and commonly used for IV placement.
Question 3 of 5
The health care provider has ordered the IV to infuse at 100 mL/hr. The tubing's drop factor is 12. Calculate the gravity infusion rate. Show your work.
Correct Answer: 20 gtt/min
Rationale: Formula: (100 mL ? 12 gtt/mL) ÷ 60 min = 1200 ÷ 60 = 20 gtt/min.
Question 4 of 5
The health care provider has ordered the IV to infuse at 75 mL/hr. The tubing's drop factor is 10. Calculate the gravity infusion rate. Show your work:
Correct Answer: 13 gtt/min
Rationale: Formula: (75 mL ? 10 gtt/mL) ÷ 60 min = 750 ÷ 60 = 12.5, rounded to 13 gtt/min.
Question 5 of 5
The health care provider has ordered the IV to infuse at 125 mL/hr. The tubing's drop factor is 20. Calculate the gravity infusion rate.
Correct Answer: 42 gtt/min
Rationale: Formula: (125 mL ? 20 gtt/mL) ÷ 60 min = 2500 ÷ 60 = 41.67, rounded to 42 gtt/min.
