Final answer:
When a person severs two phalanges immediately distal of the metacarpals, they should apply direct pressure to control bleeding and seek medical attention. The phalanges should not be removed or manipulated by the person themselves. Medical professionals will assess the injury and determine the best course of action.
Step-by-step explanation:
When a person severs two phalanges immediately distal of the metacarpals, it means that they have cut through two bones in their hand between the metacarpal bones and the fingertips. In this case, the person should keep applying direct pressure to control the bleeding. However, they should not remove or manipulate the severed phalanges themselves.
It is important to seek immediate medical attention from a healthcare professional who can properly assess and treat the injury. The healthcare professional will determine the necessary steps to provide the best care for the patient, which may involve cleaning and dressing the wound, examining the severed phalanges, and considering the possibility of surgical intervention to repair or reattach the severed parts, if possible.
Overall, the action to take in regards to the severed phalanges is to leave them untouched and seek medical help promptly.
