Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Types of Solutions Crystalloid Solutions (Cont’d) –Isotonic Solutions Same concentration of dissolved substance as plasma Maintains fluid balance when NPO –Hypotonic Solutions Fewer dissolved substances than plasma Rehydrates fluid-deficit clients Temporarily increases blood pressure

Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Is the following statement true or false? Hypotonic IV solutions increase blood pressure permanently.

Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer False. Hypotonic IV solutions may increase blood pressure temporarily.
