a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition. Thus leading us to the guiding question of the lab: what are the identities of the unknown solutions?

and indigestion. Steroids: Steroids are used to treat moderate to severe Crohn’s disease. They are commonly used when patient is hospitalized to reduce the chronic symptoms. They can be given orally‚ intravenously or rectally as suppositories or enemas. The commonly used oral steroids are prednisone (Deltasone) and methylprednisolone (Medrol‚ Solu-Medrol). Mode of action: Steroids work by affecting the immune system. It helps to control the inflammation in the GI tract by shutting down the entire

Alignment- We must ensure we have proper body alignment when using good body mechanics. Grounded- When in the clinical setting its best to keep all equipment grounded to avoid trips and falls. Material Safety Data Sheet- If something spills in the hospital or clinical setting you can always refer to their material safety data sheet to read up on the procedure. pressure ulcers – Pressure ulcers are difficult to heal; and forms when the body pressures against the surface for a long period of time
