Monitoring Parameters for Fluid and Electrolyte Imbalances

A 65-year-old patient is admitted to the emergency department with confusion and lethargy. Upon assessment, the nurse notes decreased skin turgor, dry mucous membranes, and tachycardia. Laboratory results indicate sodium level of 150 mEq/L, potassium level of 3.5 mEq/L, and a elevated serum osmolality of 310 mOsm/kg. Based on these findings, the nurse should recognize signs of fluid and electrolyte imbalances.
