A child has been hospitalized for the treatment of hematogenous osteomyelitis. The defining characteristic of this type of osteomyelitis is:
A) The presence of dead bone tissue
B) Introduction of microorganisms from the bloodstream
C) Bacterial proliferation in the absence of the classic signs of infection
D) Destruction of the vascular network in the endosteum
Ans: B
Feedback:
Hematogenous osteomyelitis originates with infectious organisms that reach the bone through the bloodstream. Dead bone tissue is indicative of osteonecrosis, not osteomyelitis. Hematogenous osteomyelitis is normally accompanied by the classic signs and symptoms of infection; the destruction of the vascular network in the endosteum is not a hallmark of the hematogenous variant of osteomyelitis.
