Which of the following rates would be considered to be a 'keep the vein open' rate?
- A. 30 mL/hr
- B. 75 mL/hr
- C. 80 mL/hr
- D. 100 mL/hr
Correct Answer: A
Rationale: A 'keep vein open' rate is typically low, around 20-30 mL/hr, to maintain patency without significant fluid delivery.

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.
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.
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.
In reference to the blood vessels, a word that means hardened is
- A. Aneurysm
- B. Sclerosis
- C. Stenosis
- D. Varicosity
Correct Answer: B
Rationale: Sclerosis describes the hardening of blood vessels, often due to plaque buildup or aging.
When you are administering hypotonic IV solutions, you know that the fluids are going to
- A. Cause shifting of body fluids into the intravascular space.
- B. Cause shifting of body fluids from the intracellular spaces into the interstitial spaces.
- C. Cause shifting of body fluids out of the intravascular space and into the interstitial spaces, and then eventually into the intracellular spaces, rehydrating the cells.
- D. Remain in their original fluid compartments.
Correct Answer: C
Rationale: Hypotonic solutions have lower osmolarity, causing fluid to move from the intravascular space into cells, aiding rehydration.
