Question

In which of the following circumstances would external bleeding be the LEAST difficult to control?

A. Lacerated carotid artery; BP of 90/50 mmHg
B. Lacerated femoral vein; BP of 70/40 mmHg
C. Lacerated brachial artery; BP of 140/90 mmHg
D. Lacerated jugular vein; BP of 100/60 mmHg

Answer 1

Controlling external bleeding would be least difficult for a lacerated femoral vein with a BP of 70/40 mmHg because veins have lower pressure and the lower BP means blood escapes with less force.

Step-by-step explanation:

The least difficult external bleeding to control among the given options would be in circumstance B: a lacerated femoral vein with a blood pressure (BP) of 70/40 mmHg. The reason for this is twofold. First, veins are under less pressure than arteries, making them easier to control when injured. Second, the lower BP in this scenario indicates that the blood would be escaping with less force compared to a scenario with higher blood pressure, making the bleeding easier to manage and control.
