It is absolutely possible for a first aid provider to cause further injury to a casualty. For this reason, it is recommended that one only provide care that they are comfortable giving. For example, someone trained in basic first aid should never attempt to give an emergency tracheotomy in order to provide an airway. However, under normal situations, it is not uncommon for procedures such as CPR to dislocate or break ribs, even if done properly.
The casualty is most likely experiencing an open fracture, where the bone has broken through the skin. It is important to seek immediate medical attention to prevent infection and further injury. In the meantime, the affected arm should be stabilized and the wound covered with a sterile dressing to reduce the risk of complications.
A crease in the back of the head could be due to a variety of reasons, including natural bone formation or injury. It is recommended to consult with a healthcare provider for a proper evaluation to determine the cause and whether any further investigation or treatment is needed.

It is difficult to say whether or not it is safe for your brother to run with a leg injury. It would really depend on the severity of the injury he suffers. If he is not in severe pain, then he could likely do some light running but I would strongly advise that he asks the opinion of his doctor before taking on any further running.
You will likely experience a withdrawal reflex, where your foot automatically jerks away from the painful stimulus of the glass. This reflex helps to protect your foot from further injury.
The most likely threat to a casualty's life in combat is severe bleeding, followed by airway obstruction and tension pneumothorax. It is crucial to address these life-threatening injuries quickly to provide the best chance of survival.
The spurting bright red blood indicates that the casualty has likely damaged an artery, specifically a major one like the radial or brachial artery, depending on the location of the wound. Arterial bleeding is characterized by its bright red color and rhythmic spurting, which correlates with the heartbeat. Immediate medical attention is necessary to control the bleeding and assess the extent of the injury.
The likely word is "injury" (physical harm).
Unless you like teeth embedded in your arm, go see the vet. Dislocations can not, and will not, correct themselves. The dog needs to be anesthetised before anyone can safely reset the joint. Doing it yourself will likely result in injury to you and further injury to the dog.

An insect bite would be considered a wound, which is another term for a minor injury. However, if the bite caused an infection or triggered an allergic reaction, that would more than likely upgrade the situation to an injury. And if the bite happened to be the vector for an insect-borne disease (such as West Nile virus or malaria) you might even upgrade it further by labeling it the entry point of a chronic condition.
