Question 1

A patient has sustained a human bite on the hand during a fist fight. Which is especially concerning with this type of bite injury?&#10;A) Possible exposure to rabies virus&#10;B) Potential septic arthritis or osteomyelitis&#10;C) Sepsis from Capnocytophaga canimorsus infection&#10;D) Transmission of human immunodeficiency virus

Accepted Answer

Human bites to the hand can lead to deep tissue infections, including septic arthritis or osteomyelitis, which can be difficult to treat and may result in permanent damage to the affected joint or bone. Additionally, there is a risk of infection from the oral flora of the aggressor, which includes anaerobes and bacteria such as Capnocytophaga canimorsus. Rabies and HIV transmission through human bites are rare, but possible.

Question 2

Which type of bite is generally closed by delayed primary closure? (Select all that apply.)&#10;A) Bites to the face&#10;B) Bites to the hand&#10;C) Deep puncture wounds&#10;D) Dog bites on an arm&#10;E) Wounds 6 hours old or older

Accepted Answer

Bites to the hand, deep puncture wounds, and wounds that are 6 hours old or older are typically closed by delayed primary closure to reduce the risk of infection. This approach allows time for observation and treatment of any potential infection before the wound is closed.

Question 3

A) Infection is a likely outcome for a dog bite.
B) Dog bites generally result in serious injury.
C) Neurovascular and destructive soft tissue injuries can occur from such a bite.
