Correct Answer » C
Explanation

The image shows a green intravenous (IV) cannula, which corresponds to an 18-gauge (18G) cannula.
- Color: Green
- Gauge: 18G
- Common use: Blood transfusion, rapid fluid resuscitation, trauma, and major surgery.
The patient has:
- Hypotension (90/60 mmHg)
- Tachycardia (120/min)
- History of trauma
These findings are suggestive of hypovolemic shock, requiring rapid intravenous fluid resuscitation using a large-bore IV cannula.
An 18G (green) cannula has an approximate flow rate of 90 mL/min (values may vary slightly among manufacturers).
