Final answer:
In an older patient, the first sign of traumatic internal bleeding may be hemorrhagic shock or external bleeding from wounds or breaks in blood vessels.
Step-by-step explanation:
In an older patient, the first sign of traumatic internal bleeding may vary depending on the severity of the bleeding. However, a common manifestation is hemorrhagic shock which is characterized by a rapid, weak pulse, cool and clammy skin, rapid breathing, and low blood pressure.
Bleeding may also present externally as hemorrhage from wounds or breaks in blood vessels. This can be a visible sign of internal bleeding in older patients.
If you suspect traumatic internal bleeding in an older patient, it is important to seek immediate medical attention for proper diagnosis and treatment.
