ASSESSMENT TESTED CONTENT WITH
ACCURATE SOLUTIONS
◉ human bites. Answer: -Result in puncture wounds or lacerations
-High risk of infection: oral bacterial flora (Staph and Strep)
-Risk for hepatitis virus
-Risk for tissue damage
-Human jaw has great crushing ability
-Infection rates as high as 50% when treatment is not obtained
within 24 hrs
-Hands, fingers, ears, nose, vagina, and penis are the most common
sites of human bites and are frequently a result of violence or sexual
activity.
-Patients with Boxer's fracture (fracture of the fourth or fifth
metacarpal) often have concurrent open wounds on the knuckles
from striking teeth.
-The human jaw has great crushing ability, causing laceration,
puncture, crush injury, soft tissue tearing, and even amputation.
-Wounds over joints
-Wounds > 6-12 hours old
-Puncture wounds
Bites on hand or foot
,Initial Treatment:
-Clean with copious irrigation, debridement, tetanus prophylaxis,
and analgesics
-Prophylactic antibiotics for bites at risk for infection
-Leave puncture wounds open; don't suture closed open or loose
sutures due to infection/ abscesses.
-Splint wounds over joints.
-Lacerations are loosely sutured.
-However, initial closure is used for facial wounds.
-The patient is admitted for IV antibiotic therapy when an infection
is present.
-These patients have an increased incidence of cellulitis,
osteomyelitis, and septic arthritis.
-Report animal and human bites to the police as required.
-People with vagina or penis bites often have trouble peeing:
swelling makes it hard to void
◉ bug injuries. Answer: -Fleas, black widow, ticks, fire ants
-Animals, spiders, snakes, and insects cause injury and even death
by biting or stinging.
-Morbidity is a result of either direct tissue damage or lethal toxins.
-Direct tissue damage is a product of animal size, characteristics of
the animal's teeth, and strength of the jaw.
,-Tissue is lacerated, crushed, or chewed, while teeth, fangs, stingers,
spines, or tentacles release toxins that have local or systemic effects.
-Death associated with animal bites is due to blood loss, allergic
reactions, or lethal toxins.
-Little kids can go into anaphylactic shock from red ant bites
-The Hymenoptera family includes bees, yellow jackets, hornets,
wasps, and fire ants.
-Stings can cause mild discomfort or life-threatening anaphylaxis.
-Venom may be cytotoxic, hemolytic, allergenic, or vasoactive
-Ticks live throughout the United States, but are most common in the
northwestern, Rocky Mountain, and northeastern regions.
-Conditions associated with tick bites include Lyme disease, Rocky
Mountain spotted fever, and tick paralysis.
-The infected tick or the release of neurotoxin causes the disease.
-Ticks release neurotoxic venom as long as the tick head attaches to
the body.
-Therefore safe removal of the tick is essential for effective
treatment.
-Use forceps or tweezers to grasp the tick close to the point of
attachment and pull upward in a steady motion.
-After you remove the tick, clean the skin with soap and water.
, -Do not use a hot match, petroleum jelly, nail polish, or other
products to remove the tick, since these measures may cause a tick
to salivate, thus increasing the risk for infection.
-Lyme disease is the most common tick-borne disease in the United
States.
-Symptoms appear within days of a bite from the Ixodid (hard) tick
that has been attached for at least 48 hours
-The fir
◉ anaphylactic shock. Answer: -Introduction of an antigen into a
sensitive individual, initiating an antigen-antibody response
-Release of vasoactive mediators and histamine
-As antigens enter the body, antigens are produced that attach to
mast cells and basophils.
-Mast cells in the lungs, around blood vessels, in connective tissue,
and in the uterus release vasoactive mediators in response to
exposure to a common antigen that causes anaphylaxis.
-Causes: severe allergic reaction
Clinical Manifestations:
-The clinical presentation of anaphylactic shock consists of upper
and lower airway, angioedema, cardiovascular, and integumentary
symptoms.
