Question 1 of 5
The nurse has an order to give 500 mL of 0.45% NS over 12 hours. The IV set has a drop factor of 10. How many gtts/min should the client receive? Fill in the blank.
Correct Answer: 7
Rationale: Rate = 500 mL ÷ 12 hr = 41.67 mL/hr. Drops/min = (41.67 mL/hr × 10 gtts/mL) ÷ 60 min = 6.94 gtts/min, rounded to 7 gtts/min.

Question 3 of 5
A client has a chest tube in place with a three-chamber chest drainage system. The nurse notes continuous bubbling in the water seal chamber. This indicates which of the following?

Correct Answer: C
Rationale: Nasal cannula at 3 L/min delivers approximately 32% FiO2 (
C), as each liter increases FiO2 by about 4% above room air (21%). Other percentages (A, B,
D) do not correspond to this flow rate.
