Question

A preop nurse is initiating peripheral intravenous access on a client scheduled for surgery. The nurse selects an 18-gauge catheter for insertion. The client asks the nurse why the catheter needs to be so large. How will the nurse respond to the client's concern?

"You may require rapid fluid infusions during the surgery."

"I can use a smaller gauge if that makes you feel comfortable."

"You have large veins that can accommodate this catheter."

"Tell me why you are concerned about the size of the catheter."

Answer 1

The nurse would explain that the 18-gauge catheter is chosen for its ability to allow rapid fluid infusions during surgery, which is important for patient safety and the fluid administration requirements of the procedure.

Step-by-step explanation:

The nurse's response to the client's concern about the size of the catheter is pivotal for ensuring the patient's understanding and comfort with the medical procedure. When selecting an 18-gauge catheter for peripheral intravenous access, the nurse has considered several factors, including the need for rapid fluid infusion during surgery, which is a common practice to maintain appropriate blood pressure and hydration levels. It is important to note that smaller gauge catheters might not provide the necessary flow rate for such purposes, hence the selection of a larger gauge.

For patients in surgery or intensive care, accurate and reliable intravenous access is crucial for administering medication, fluids, or for obtaining pressure measurements, as these are typically more invasive procedures. The larger catheter size ensures that large volumes of fluids or blood products can be delivered quickly if necessary. Therefore, the nurse's choice is geared towards patient safety and the specific needs of the surgical process.
