Question

your treatment choices are saline solutions with different amounts of salt (nacl) which can affect osmosis in the brain. in medicine and veterinary medicine, saline solutions are compared with the normal concentration of sodium (~143 mmol/l) in healthy blood. three saline solutions are available: isotonic, hypotonic, and hypertonic. interpret each as higher, lower, or equal to normal blood na+ concentration.
isotonic saline
lower
equal
higher
hypotonic saline
lower
equal
higher
hypertonic saline
lower
equal
higher

Explanation:

Isotonic saline has a sodium - ion concentration equal to that in normal blood. Hypotonic saline has a lower sodium - ion concentration than normal blood. Hypertonic saline has a higher sodium - ion concentration than normal blood.

Answer:

Isotonic Saline: Equal
Hypotonic Saline: Lower
Hypertonic Saline: Higher
