2. 0.9% sodium chloride (NS)
3. 0.45% sodium chloride

5. 5% dextrose in water
Correct Answer: 2,4,5
Rationale 1: This is a hypertonic solution and is not appropriate for the treatment of fluid loss due to a surgical procedure.
Rationale 2: This is an isotonic solution and is appropriate for the treatment of fluid loss due to a surgical procedure.
Rationale 3: This is a hypotonic solution and is not appropriate in the treatment of fluid loss due to a surgical procedure.
Rationale 4: This is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure.
Rationale 5: This is an isotonic solution that is appropriate to treat fluid loss caused by a surgical procedure.
Global Rationale: 0.9% sodium chloride (NS), Lactated Ringers, and 5% dextrose in water are all isotonic solutions that are appropriate to treat fluid loss caused by a surgical procedure. 5% dextrose in Lactated Ringers 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.
