The plastic projection that provides a place for your fingers to push the piercing pin into the solution bag port without contaminating the sterile piercing pin is known as the
- A. Flange
- B. Spike
- C. Clamp
- D. Port
Correct Answer: A
Rationale: The flange is a plastic projection on IV tubing that allows sterile insertion of the piercing pin.

Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: D5\%NS
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: C
Rationale: D5%NS is hypertonic due to added dextrose, increasing osmolarity above plasma.
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.
Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: 0.45% NS
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: B
Rationale: 0.45% NS is hypotonic, with lower osmolarity than plasma, causing fluid to enter cells.
What is the term for removing air from the IV tubing?
- A. Flushing
- B. Priming
- C. Purging
- D. Venting
Correct Answer: B
Rationale: Priming the IV tubing removes air to prevent air embolism during infusion.
Which type IV solution will cause cellular dehydration if infused unnecessarily?
- A. Isotonic solution
- B. Hypotonic solution
- C. Hypertonic solution
Correct Answer: C
Rationale: Hypertonic solutions draw water out of cells due to high osmolarity, causing cellular dehydration if not needed.
