Identify the color of the IV cannula used in the pediatrics unit?

Appeared in: NORCET 1 - 2020

Explanation

The yellow color-coded hub on an IV cannula signifies a 24-gauge (24G) size.
A 24G cannula is recommended for pediatric and neonatal patients because their veins are smaller and more fragile.
Using a smaller gauge minimizes insertion-related trauma and reduces the risk of complications like infiltration and phlebitis in children.

Option B: An orange cannula is 14G, which is the largest bore size. It is used for rapid, large-volume fluid resuscitation in adult trauma patients and is completely unsuitable for a child's small veins.
Option C: A grey cannula is 16G, a large bore catheter used for rapid fluid or blood administration during surgery or trauma in adults. It is too large and would damage a child's vein.
Option D: A green cannula is 18G. While smaller than 14G or 16G, it is still considered a large cannula and is typically used for blood transfusions or medication administration in adults. It is generally too large for most pediatric patients.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain IV cannula color coding and appropriate size selection for pediatric patients as background academic context rather than a clinical decision trigger.
Selecting the correct IV cannula size is a critical nursing skill that directly impacts patient safety and comfort.
Using a cannula that is too large for the vein can cause significant pain, infiltration, extravasation (leakage of vesicant drugs), and thrombophlebitis, leading to loss of IV access and potential tissue damage.
In pediatric nursing, meticulous site selection and using the smallest effective gauge are paramount to preserving venous access for potential future needs.

How to Approach the Question

First, identify the core of the question, which is asking for the specific IV cannula color used for the 'pediatrics' patient population.
Recall or reference the standard color-coding system for IV cannulas. The image provided serves as a direct reference.
Associate the patient population (pediatrics) with the appropriate cannula size. Children have small, fragile veins, so they require a small gauge (higher number) cannula.
Look at the provided image or recall that a 24-gauge cannula is indicated for pediatric use.
Identify the color associated with the 24-gauge cannula, which is yellow.
Select the option that matches this color.

Concept Tested & Keywords

Concept Tested: IV cannula color coding and appropriate size selection for pediatric patients.
Stem keywords: IV cannula, pediatrics unit, color
Lead-in keywords: Identify
Clinical cues: The term 'pediatrics unit' is a key clinical cue, indicating the patient population is children, which requires specialized equipment like smaller gauge cannulas.
