Which of the following restrictions is(are) accurate with regard to selecting a vein for use when restarting an infiltrated IV?
- A. You cannot use the same vein again for 12 hours.
- B. You should use the same arm again to prevent soreness in both of the patient's arms.
- C. If you use the same vein where the IV infiltrated, you must use a site distal to the old site.
- D. The best veins to use are those of the forearm.
- E. Once an IV has infiltrated in the forearm, it should be restarted in the hand on that arm.
Correct Answer: C
Rationale: Using a distal site on the same vein avoids complications from the infiltrated area.

Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: D51/2NS
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: C
Rationale: D5 1/2 NS is hypertonic due to dextrose and sodium content, drawing fluid from cells.
Because of the fluid shifts in the previous question, prolonged infusion of this type solution when it is not needed can result in which of the following?
- A. Cerebral cells swelling
- B. Increased intracranial pressure
- C. Dehydration of cells
- D. Edema
Correct Answer: A,B,D
Rationale: Excess hypotonic fluid can cause cerebral swelling, increased intracranial pressure, and edema due to fluid overload in cells and interstitial spaces.
You are about to attempt to initiate an IV on a 97-year-old female with tiny, fragile veins. Which of the following access devices would most likely be your best choice?
- A. 27 g ? 1 in winged butterfly without cannula
- B. 22 g ? 1¼ in intracath
- C. 25 g ? 1 in winged butterfly with cannula
- D. 23 g ? 1 in intracath
Correct Answer: C
Rationale: A $25 \mathrm{~g}$ winged butterfly with cannula is small and suitable for fragile veins, providing stability and reducing trauma.
Which solution is best when an individual needs only simple water replacement because of lack of fluid intake or loss of body water without loss of electrolytes, known as hypertonic dehydration?
- A. Isotonic solution
- B. Hypotonic solution
- C. Hypertonic solution
Correct Answer: B
Rationale: Hypotonic solutions provide water to rehydrate cells without adding excess electrolytes, suitable for hypertonic dehydration.
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.
