Intravenous solutions administered in medicine, such as saline and Ringer's solution, are always isotonic. Explain why this is important and specifically what the potential outcomes could be for patients who do not receive isotonic solutions intravenously.

Step 1
Step 1: Isotonic solutions have the same osmotic pressure as blood, ensuring that they do not change the concentration of molecules in the bloodstream when administered intravenously. Show more…

Both of the regular intravenous solutions administered in medicine, normal saline and lactated Ringer's solution, are isotonic. Why is this important? a. Isotonic solutions maintain equilibrium and avoid the exchange of materials to or from the blood. b. Isotonic solutions disrupt equilibrium and allow better exchange of materials in the blood. c. Isotonic solutions increase the $\mathrm{pH}$ of blood and allow better absorption of saline in blood. d. Isotonic solutions decrease the pH of the blood and avoid the exchange of materials to or from the blood.

Why is the concept of tonicity important when giving intravenous infusions? When is an isotonic solution given to a patient? Propose circumstances other than those described in your lab manual when a hypertonic or a hypotonic solution might be administered.

For most intravenous injections, great care is taken to ensure that the concentration of solutions to be injected is comparable to that of blood plasma. Explain.
