The nurse is expecting the admission of a child with severe isotonic dehydration. Which intravenous fluid should the nurse anticipate the doctor to order initially to replace fluids?
1. 0.9% normal saline (NS)
2. D5 0.2% (¼) normal saline
3. D5W
4. Albumin
1
Rationale 1: 0.9% normal saline (NS) is an isotonic fluid and maintains Na and chloride at present levels.
Rationale 2: D5 0.2% (¼) normal saline would not be used initially but later, as maintenance fluids.
Rationale 3: D5W can lower sodium levels, and so it would not be used to replace fluids in severe isotonic dehydration.
Rationale 4: Albumin is used to restore plasma proteins.
