Final answer:
The abdomen will be soft even if there is bleeding because the body initially tenses up after trauma.
Step-by-step explanation:
On examination of an abdomen immediately following blunt trauma, the abdomen will be soft even if there is bleeding because the body's initial response to trauma is to tense up, protecting the organs by contracting the abdominal muscles. This contraction can mask the signs of internal bleeding, making the abdomen feel soft during the initial examination.
