• balancing the body's pH level
• moving waste out of body cells
• moving nutrients into body cells
• allowing the body's muscle, heart, nerves, and brain to function properly

• what osmolarity level is too dilute?

Answer Na+ < 135 mEq/L Osm < 280 mosmol/kg

• what is the optimal osmolarity level?

Answer Na+ = 135-145 mEq/L Osm = 280-330 mosmol/kg

• what osmolarity level is too concentrated?

Answer Na+ > 145 mEq/L Osm > 300 mosmol/kg

• what is hypokalemia level?

Answer K+ < 3.5 mEq/L
