RNSG 1533 Exam 1What are complications of IVFs? - correct answer Isotonic Solution: CAUTION- Can cause FVE and hyperchloremic acidosis if used in excess volumes. Hypotonic Solution: CAUTION- Can cause cardiovascular collapse & increase intracranial pressure (cells blow up-hemolysis). Hypertonic Solution: CAUTION- Give SLOWLY, it can cause FVE & pulmonary edema. Cells will begin to shrink and die. General IV complications and their treatments/preventive measures: - Fluid overload: Diste...
