- What are signs and symptoms?
In medicine a symptom is generally subjective while a sign is objective. Any objective evidence of a disease, such as blood in the stool, a skin rash, is a sign - it can be recognized by the doctor, nurse, family members and the patient. However, stomachache, lower-back pain, fatigue, for example, can only be detected or sensed by the patient - others only know about it if the patient tells them.

To sum it up, signs are what a doctor sees and symptoms are what the patient experiences.
2. When do we use a medical device such as bandaging?
Basically, we use bandage to prevent loss of blood if someone's having a wound. This may also be used for binding up fractures and other injuries and to hold dressing in place, to apply pressure or to immobilize a wound.
3. Where do bandages applied?
Bandages are usually used in some injured parts of the body. (e.g. leg, finger, arm, hand)
4. Why is there a need for bandaging injured parts of the body?
So that we may control the bleed (because excessive loss of blood can cause unconsciousness or even death) and to support a fracture or sprain/strain.
5. How do we apply bandage?
First is, we hold the bandage with the roll uppermost and start to roll around the wound upwards. For every turn, use a firm even pressure.
Then with each turn, we cover two-thirds of the width of the previous one. Avoid covering the tips of the fingers and toes.
And lastly, we fasten the bandage with a small safety pin or a bandage clip.
