Answer:
Arteriosclerosis are plaques that form within the arteries, producing a decrease in arterial lumen. These plaques are usually made up of fatty tissue, calcium, cholesterol, fats found in the blood.
They are not healthy because they reduce the flow of oxygenated blood to the tissues, producing ischemia or cellular necrosis, for example acute myocardial infarction (when it comes to coronary artery obstruction) or vascular brain disease when the aortic artery is clogged.
Answer:
A. The material can easily release oxygen to create or worsen a fire or explosion hazard
Explanation:
The NFPA (National Fire Protection Association) diamond, is divided in four colors. The bottom quadrant of the white color symbol, and identify different types of special hazards.
In particular, OX refers to a solid or liquid chemical oxidizing agent that oxidize or accept electrons from other chemical compounds (such as combustible/burnable materials) by redox reactions. These materials also can readily give off oxygen or other oxidizing substances (such as bromine, chlorine, or fluorine). For this reason, the oxygen combined to other materials may increase the chance of an accidental fire or explosion.
Some examples of these compounds are: H₂O₂, KMnO₄, K₂CrO₇, NH₄ClO₄.

Answer:
The most appropriate immediate treatment for this child is administration of ISOTONIC CRYSTALLOID
Explanation:
Diarrhea in children should be treated properly to avoid dehydration which is the usually the cause of death in most cases. The most common causes of diarrhea are Infections of viral, bacterial or parasitic origin and it is characterized with drastic loss of fluid through watery and loose stools.
The signs and symptoms observed in the 3-year-old child indicates dehydration due to loss of fluid from a history of Diarrhea. Therefore administration of ISOTONIC CRYSTALLOID should be used to rehydrate the child once vascular access is obtained.
The isotonic crystalloids are standard intravenous (IV) fluids used for initial volume resuscitation. They expand the intravascular and interstitial fluid spaces. Examples include:
--> sodium chloride solution (normal saline [NS]) and
--> lactated Ringer (LR) solution.
