Name four of the most commonly used veins for IV initiation.
- A. Cephalic, basilic, median cubital, radial
- B. Cephalic, basilic, median cubital, dorsal hand veins
- C. Brachial, radial, ulnar, saphenous
- D. Femoral, jugular, subclavian, cephalic
Correct Answer: B
Rationale: Cephalic, basilic, median cubital, and dorsal hand veins are large, accessible, and commonly used for IV placement.
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 health care provider has ordered the IV to infuse at 30 mL/hr. The tubing's drop factor is 60. Calculate the gravity infusion rate.
Correct Answer: 30 gtt/min
Rationale: Formula: (30 mL ? 60 gtt/mL) ÷ 60 min = 1800 ÷ 60 = 30 gtt/min.
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.
Match each IV fluid with the appropriate term that accurately describes the solution's tonicity: 0.9% NS
- A. Isotonic
- B. Hypotonic
- C. Hypertonic
Correct Answer: A
Rationale: 0.9% NS is isotonic, matching plasma osmolarity, so fluid stays in the intravascular space.
