Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: Normosol R
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: A
Rationale: Normosol R is isotonic, designed to match plasma osmolarity.

Which of the following explanations of the differences between IV push and IVPB routes of administration are correct?
- A. The IV push route of administration allows direct infusion from the bag of solution at a rapid rate, which pushes the medication in quickly.
- B. The IVPB route of administration allows medications to infuse over a 1- to 2-minute interval.
- C. The IVPB route of administration requires that the medication be dissolved in a volume of fluid, ranging between 50 and 250 mL.
- D. The IV push route of administration provides for direct injection of medication into the port closest to the IV site.
Correct Answer: C,D
Rationale: IVPB involves medication diluted in 50-250 mL, infused over a longer period, while IV push is a direct, rapid injection into the IV port.
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
- A. Infiltration
- B. Extravasation
- C. Embolism
- D. Thrombosis
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.
The interaction between the two drugs that causes a change in the activity or components of one or more of the drugs is known as a
- A. Synergism
- B. Drug interaction
- C. Antagonism
- D. Precipitation
Correct Answer: B
Rationale: A drug interaction occurs when one drug alters the effect or composition of another, potentially affecting efficacy or safety.
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.
Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: 1/2 NS
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: B
Rationale: 1/2 NS (0.45% NS) is hypotonic, promoting fluid shift into cells.
