Answer:
Q1) Administering a 10% salt solution intravenously could result in numerous harmful effects.
Q2) The tissue should be placed in a formalin solution or another preservative to maintain its integrity.
Explanation:
Q1) Typically, a 0.9% sodium chloride injection is used to restore fluids and electrolytes, correct metabolic alkalosis, supplement sodium levels, and dilute medications. A 10% concentrated salt solution is unsafe for direct injection; it must be diluted accordingly. Injecting it directly may cause hypernatremia, cardiovascular collapse, neurological complications, severe destruction of red blood cells, kidney tissue death, and severe tissue damage if leakage occurs.
Q2) After collecting a biopsy, it is immersed in a formalin-based fixative (a mixture of formaldehyde and water) or another preserving agent. The fixative must have a pH close to that of blood to avoid chemical alteration of the tissue, ensuring future diagnostic assessments—especially Immunohistochemical and Molecular Biology analyses—remain accurate.
