you can apply ice directly when there is external bleeding. State whether the above statement is true or false
Answers
Answer:
Bleeding is a common reason for the application of first aid measures and can be internal or external. The principle difference is whether the blood leaves the body - external bleeding can be seen, whereas in internal bleeding, no blood can be seen.
There are many causes of external bleeding, which fall in to seven main categories, which are:
Abrasion - Also called a graze, this is caused by transverse action of a foreign object against the skin, and usually does not penetrate below the epidermis
Excoriation - In common with Abrasion, this is caused by mechanical destruction of the skin, although it usually has an underlying medical cause
Laceration - Irregular wound caused by blunt impact to soft tissue overlying hard tissue or tearing such as in childbirth
Incision - A clean 'surgical' wound, caused by a sharp object, such as a knife
Puncture Wound - Caused by an object penetrated the skin and underlying layers, such as a nail, needle or knife
Gunshot wounds - Caused by a projectile weapon, this may include two external wounds (entry and exit) and a contiguous wound between the two
Recognition
Minor bleeding from an abrasion.
Recognizing external bleeding is usually easy, as the presence of blood should alert you to it. It should however be remembered that blood may be underneath or behind a victim. It may be difficult to find the source of bleeding, especially with large wounds or (even quite small) wounds with large amounts of bleeding. If there is more than 5 cups of blood from a wound, then the wound is life-threatening.
Treatment
Bleeding from a thumb wound.

Put gloves on before coming into contact with any blood or body fluids.
As with all first aid situations, the priority is to protect yourself, so put on protective gloves before approaching the victim.
All external bleeding is treated using three key techniques, which allow the body's natural repair process to start. These can be remembered using the acronym mnemonic 'RED':
Rest
Elevation
Direct pressure
Rest
In all cases, the less movement the wound undergoes, the easier the healing process will be, so rest is advised. Rest will also reduce the pulse rate, thus the severity of the bleeding, especially in the case of arterial bleeding.
Elevation
A rescuer applying direct pressure and elevating the arm for an arm laceration.
Direct pressure is usually enough to stop most minor bleeds, but for larger bleeds, it may be necessary to elevate the wound above the level of the heart (whilst maintaining direct pressure the whole time). This decreases the blood flow to the affected area, slowing the blood flow, and assisting clotting.
Elevation only works on the peripheries of the body (limbs and head) and is not appropriate for body wounds. You should ask the victim to hold their wound as high as possible. You should assist them to do this if necessary, and use furniture or surrounding items to help support them in this position. If it is the legs affected, you should lie them on their back (supine), and raise their legs.
Direct Pressure
The most important of these three is direct pressure. This is simply placing pressure on the wound in order to stem the flow of blood. This is best done using a dressing, such as a sterile gauze pad (although in an emergency, any material is suitable).
If the blood starts to come through the dressing you are using, add additional dressings to the top, to a maximum of three. If you reach three dressings, you should remove all but the one in contact with the wound itself (as this may cause it to reopen) and continue to add pads on top. Repeat this again when you reach three dressings. The reason for not simply adding more dressings is that it becomes harder to apply the direct pressure which is clearly needed if this much blood is produced.

Explanation:
True
Explanation:
- The external bleeding is a condition through which the blood can leave the body from the injury or wound.
- The external bleeding occurs due to rupture of the blood vessels, which causes the blood to flow out of the blood vessels.
- The application of ice to the wound or injury will constrict the blood vessels. This will help in formation of the clot.
- The best way for application of ice to the skin is to wrap the ice to the clean cloth and place the ice over the skin.
