Comprehensive Nursing Pharmacology Q 295
An order is written to start an IV on a 74-year-old client who is getting ready to go to the operating room for a total hip replacement. What gauge of catheter would best meet the needs of this client?
A. 18
B. 20
C. 21 butterfly
D. 25
Correct Answer: A. 18
Clients going to the operating room ideally should have an 18- gauge catheter. This is large enough to handle blood products safely and to allow rapid administration of large amounts of fluid if indicated during the perioperative period. An 18-gauge catheter is recommended.
Option B: A 20-gauge catheter is a second choice. One may be able to push blood* through this size if an 18 gauge can’t be used, but always check the employer’s protocol. This size is better for patients with smaller veins.
Option C: A 21-gauge needle is too small and a butterfly too unstable for a client going to surgery. Mostly used for transfusions in pediatric, neonate, and older adult patients.
Option D: A 25-gauge needle is too small. It is most commonly used for neonatal and pediatric patients.
