The nurse is reviewing the tonicity of the different intravenous fluids on the medical-surgical unit in preparation for an educational presentation. Which fluids are considered to be isotonic and appropriate in the treatment of fluid loss due to a surgical procedure?
1. 5% dextrose in lactated Ringer's
2. 0.9% sodium chloride (NS)
3. 0.45% sodium chloride
4. Lactated Ringer's
5. 5% dextrose in water
2,4,5
Rationale 1: 5% dextrose in lactated Ringer's is a hypertonic solution and is not appropriate for the treatment of fluid loss due to a surgical procedure.
Rationale 2: 0.9% sodium chloride (NS) is an isotonic solution and is appropriate for the treatment of fluid loss due to a surgical procedure.
Rationale 3: 0.45% sodium chloride is a hypotonic solution and is not appropriate in the treatment of fluid loss due to a surgical procedure.
Rationale 4: Lactated Ringer's is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure.
Rationale 5: 5% dextrose in water is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure.
Global Rationale: 0.9% sodium chloride (NS) is an isotonic solution and is appropriate for the treatment of fluid loss due to a surgical procedure. Lactated Ringer's is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure. 5% dextrose in water is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure. 5% dextrose in lactated Ringer's is a hypertonic solution and is not appropriate for the treatment of fluid loss due to a surgical procedure. 0.45% sodium chloride is a hypotonic solution and is not appropriate in the treatment of fluid loss due to a surgical procedure.
