### Understanding Salinity in IV Drips **Question 7:** Use what you know about blood cells, tonicity, osmosis, and diffusion to explain why an IV drip administered in a medical setting needs to be the correct salinity. **Include** evidence from the blood cell observations you made to support your claim. **Hint:** Remember hypertonic and hypotonic. When administering an IV drip in a medical setting, it is crucial to ensure that the solution has the correct salinity relative to the patient's blood. Blood cells and their interactions with their environment, particularly through processes such as osmosis and diffusion, can be greatly affected by the tonicity of the solution: - **Isotonic solution**: An isotonic solution has the same concentration of solutes as the blood cells. This balance prevents the net movement of water into or out of the cells, maintaining cell integrity and function. - **Hypertonic solution**: A hypertonic solution has a higher concentration of solutes compared to the blood cells. This causes water to move out of the cells (osmosis), leading to cell shrinkage (crenation). Overly concentrated IV solutions can dehydrate cells and impair their functions. - **Hypotonic solution**: A hypotonic solution has a lower concentration of solutes compared to the blood cells. This leads to water moving into the cells, causing them to swell and potentially burst (lysis). Overly dilute IV solutions can cause cells to swell excessively and rupture, disrupting cellular integrity and leading to potential complications. Ensuring the IV drip matches the isotonic conditions of the blood can prevent these adverse outcomes and maintain homeostasis within the patient's body. Observations involving blood cells exposed to various tonicity conditions can provide evidence for these effects, demonstrating the physical changes cells undergo when exposed to improper saline levels. This emphasizes the importance of using correctly balanced solutions in medical treatments.
