A client is exhibiting signs of increasing intracranial pressure (ICP). Which intravenous solution (IV) would the nurse anticipate hanging?
A) Dextrose 5% in water (D5W)
B) Half-normal saline (0.45% NSS)
C) One-third normal saline (0.33% NSS)
D) Mannitol (Osmitrol)
D
Feedback:
With increasing ICP, hypertonic solutions, like mannitol, are used to decrease swelling in the brain cells. D5W, 0.45% NSS, and 0.33% NSS are all hypotonic solutions that will move more fluid into the cells, worsening the ICP.
