A person is injured in an accident and there is blood spurting out from his wrist. The most correct inference is that

Options

A. He has an injured artery
B. He has an injured vein
C. He has an injured vena cave
D. He has an injured nerve

Answer

To solve the question regarding the injury sustained by a person in an accident with blood spurting from his wrist, we can analyze the situation step by step:

### Step 1: Understand the nature of the bleeding
- The question states that blood is "spurting" out from the wrist. This characteristic of bleeding is crucial. Spurting blood is typically associated with arterial bleeding, where blood is under high pressure.

**Hint:** Consider the type of blood flow and what it indicates about the type of blood vessel involved.

### Step 2: Identify the type of blood vessel involved
- In the human body, arteries carry oxygenated blood away from the heart, and they are under higher pressure compared to veins. When an artery is cut or injured, blood will spurt out rhythmically with the heartbeat.

**Hint:** Recall the difference between arteries and veins in terms of blood pressure and flow characteristics.

### Step 3: Evaluate the options provided
1. **He has an injured artery.** - This option is likely correct since spurting blood indicates arterial injury.
2. **He has been injured.** - This option is too vague and does not specify the type of vessel involved.
3. **He has an injured vena cava.** - This option is incorrect because the vena cava carries deoxygenated blood and is not typically associated with spurting blood.
4. **He has an injured nerve.** - This option is also incorrect as nerves do not cause spurting blood.

**Hint:** Analyze each option critically to determine which one directly correlates with the symptoms described.

### Step 4: Conclusion
- Based on the analysis, the most correct inference is that the person has an injured artery, as indicated by the spurting blood from the wrist.

**Final Answer:** He has an injured artery.
