USCG COXSWAIN EXAMS TEST PAPER QUESTIONS AND
ANSWERS FIRM A+
✔✔First-Degree Burns - ✔✔First-degree burns are the mildest form of burns. These
burns involve only the outer layer of
skin and produce redness, increased warmth, tenderness, and mild pain.
✔✔Second-Degree Burns - ✔✔Second-degree burns extend through the outer layers of
the skin. These burns involve the
inner layers of the skin, but not enough to prevent rapid regeneration. They produce
blisters
and are characterized by severe pain, redness, and warmth.
✔✔Third-Degree Burns - ✔✔Third-degree burns are those that penetrate the full
thickness of the skin, destroying both the
outer and inner layers. Severe pain, characteristic of second-degree burns, may be
absent
because nerve endings have been destroyed. Color may range from white and lifeless
to
black (charred). Healing requires many months, and usually results in scarring of the
skin
tissue. Skin grafts are generally required to achieve full healing.
✔✔First-Degree Treatment - ✔✔Immerse in cool water until pain is relieved.
Flush chemical burns for at least 20 minutes.
Cover with clean or sterile dressing.
✔✔Second-Degree Treatment - ✔✔Use the same treatment as for first-degree burns.
Do not break open any blisters.
Cover with a dry, sterile, non-adhesive dressing.
For deep second-degree burns, follow the procedures for thirddegree
burns.
✔✔Third-Degree Treatment - ✔✔For third-degree, or deep, second-degree burns:
Cover the burn to reduce exposure to air.
Cool the burn.
Do not remove clothing unless smoldering.
Treat for shock even if not apparent.
Always obtain medical care.
Monitor the patient's airway.
Assess vital signs every 5 minutes.
Give nothing to eat or drink.
Do not place ice on the burn.
Do not apply ointments to the burn.
,Burns of the respiratory tract are always a medical emergency.
✔✔Chemical Burns - ✔✔Wash the chemical away completely, as quickly as possible,
using large
quantities of water.
Continue flushing the burn for at least 20 minutes.
When the burn involves an eye, flush the eye with water for up to
20 minutes.
Cover both eyes with a clean, dry, protective dressing and seek medical
attention as quickly as possible.
Give first aid for shock.

✔✔Personal Marker Light - ✔✔A PML is a device that uses either battery or chemical
action to provide light for the wearer
to be seen during darkness. The yellow-green light of a PML is visible for a distance of
approximately one mile on a clear night, and lasts as long as eight hours.
The intensity of the PML's light signal in cold weather (below 10° C/50° F) is reduced. In
colder temperatures, the light will last longer, but will not have the same brilliance as in
warmer conditions.

degrees - ✔✔Anti-exposure Suit
✔✔Emergency Signal Mirror - ✔✔Light reflected in this manner can be seen at a great
distance from the point of origin.
Face a point about halfway between the sun and an object you wish to signal.
Reflect sunlight from the mirror onto a nearby surface such as the raft, your
hand, etc.
, Slowly bring the mirror up to eye-level and look through the sighting hole.
You will see a bright light spot, this is the aim indicator.

✔✔Signal Whistle - ✔✔Fox40
Depending on weather conditions, a whistle's audible sound may be heard up to 1,000
meters/1,100 yards. Any wind has the effect of carrying the sound downwind.
✔✔Smoke and Illumination Signal, MK-124 MOD 0 - ✔✔The MK-124 MOD 0 is a
pyrotechnic smoke and illumination signal used day or night as a
distress signal at sea or on land. One end produces orange smoke as the
day signal and the other end produces a red flare as the night signal.
Both ends of the device produce a signal and each end burns for about
20 seconds.
The device has two raised bands around its circumference on its night end (flare).
✔✔Illumination Signal Kit, MK-79 MOD 0 - ✔✔SDU-5/E
The MK-79 MOD 0 is a pyrotechnic illumination signal kit that contains seven MK80
screw-in
cartridge flares and one MK31 pencil-type projector. The projector in this kit is used to
aim and
fire a signal cartridge.
These signals produce a red star display at an altitude of 250-650 feet for a minimum
time of
4.5 seconds. Their luminous intensity is about 12,000 candle power.
✔✔Survival Knife - ✔✔The survival knife (see Figure 6-16) is a basic tool used to free
the crewmember from
entangling lines. It is also used to cut material blocking a path in escaping a capsized or
sinking boat. It should be a fixed blade design made of corrosion-resistant material.
✔✔Personal Locater Beacon - ✔✔The PLB is a personal transmitter capable of
broadcasting on both 406 MHz and 121.5
MHz. The international satellite based search and rescue system (COSPAS SARSAT)
monitors 406 MHz and is able to provide a position accurate to within three nautical
miles
within 90 minutes. Once the rescue platform is in the vicinity, the 121.5 MHz transmitter
provides a signal allowing the resource to home in on the vessel or individual in distress
particularly if the individual is equipped with flares and a strobe light.
✔✔Parachute Illumination Signal, MK-127A1 - ✔✔The parachute illumination signal,
MK-127A1 is a night time illumination-signaling device.
When fired, it climbs to an altitude of 650 to 700 feet before igniting. Upon ignition, it
produces a parachute-suspended white star flare that burns for about 36 seconds with
