Question 1 of 5
The IVPB is to infuse over 30 minutes. The PB solution bag is 50 mL. The tubing's drop factor is 12. Calculate the gravity infusion rate. Show your work.
Correct Answer: 20 gtt/min
Rationale: Formula: (50 mL ? 12 gtt/mL) ÷ 30 min = 600 ÷ 30 = 20 gtt/min.
Question 2 of 5
The IVPB is to infuse over 30 minutes. The PB solution bag is 100 mL. The tubing's drop factor is 20. Calculate the gravity infusion rate.
Correct Answer: 67 gtt/min
Rationale: Formula: (100 mL ? 20 gtt/mL) ÷ 30 min = 2000 ÷ 30 = 66.67, rounded to 67 gtt/min.
Question 3 of 5
The IVPB is to infuse over 20 minutes. The PB solution bag is 100 mL. The tubing's drop factor is 20. Calculate the gravity infusion rate.
Correct Answer: 100 gtt/min
Rationale: Formula: (100 mL ? 20 gtt/mL) ÷ 20 min = 2000 ÷ 20 = 100 gtt/min.
Question 4 of 5
The word that means similar to infiltration but involves leakage of vesicant IV fluid medication into the tissue surrounding the IV insertion site is known as
Correct Answer: B
Rationale: Extravasation refers to the leakage of vesicant IV fluids, which can cause severe tissue damage, unlike infiltration, which involves non-vesicant fluids.
