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