Question 23 QMED02 - Electrician-Refrigerating Engineer

The Correct Answer is D **Why option D ("Bright red blood flowing from the wound in spurts.") is correct:** Arterial bleeding occurs when an artery is damaged. Arteries carry oxygenated blood directly from the heart to the body tissues. This blood has two defining characteristics: 1. **Color:** Because it is highly oxygenated, the blood is bright red. 2. **Flow:** Arteries are under high pressure due to the pumping action of the heart (systolic pressure). When an artery is severed, the blood exits the wound corresponding to the heartbeat, resulting in a forceful flow described as "spurting" or "pulsating." **Why the other options are incorrect:** * **A) Dark red blood flowing from the wound in spurts.** This is incorrect because arterial blood is bright red (not dark red). Dark red blood indicates deoxygenated blood, characteristic of venous or capillary bleeding. * **B) Bright red blood flowing from the wound with a steady flow.** This is incorrect because while arterial blood is bright red, the flow is pulsatile/spurting (not steady) due to the high pressure from the heart. A steady flow is typically associated with lower-pressure bleeding, such as venous bleeding (although venous blood is dark red). * **C) Dark red blood flowing from the wound with a steady flow.** This describes characteristic venous bleeding (low pressure, steady flow, and deoxygenated/dark red blood), not high-pressure arterial bleeding.
