Fluid & Electrolyte Q 51

The intracellular compartment holds water and:
    A. Proteins
    B. Glucose
    C. Sodium
    D. Uric acid

Correct Answer: A. Proteins

The intracellular compartment holds large amounts of water and proteins. Potassium, lipids, and nucleic acids are also components of the intracellular compartment. Intracellular fluids tend to be inversed with high levels of phosphate, magnesium, potassium, and proteins but lower sodium, chloride, and bicarbonate. Interstitial fluids physiologically tend to have a low concentration of proteins.

Option B: Intracellular fluid is approximately 40% of the total body weight. It is the total space within cells primarily defined as the cytoplasm of cells. In general, intracellular fluids are stable and do not readily adjust to rapid changes. This space is where much of chemical reactions occur, as such, it is important to maintain an appropriate osmolality.
Option C: Extracellular fluid and interstitial fluid are similar in composition. Extracellular spaces contain high concentrations of sodium, chloride, bicarbonate, and proteins but are relatively lower in potassium, magnesium, and phosphate.
Option D: Uric acid is normally found in the body as a byproduct of the way the body breaks down certain proteins called purines. Causes of an elevated blood uric acid level (hyperuricemia) include genetics, obesity, certain medications such as diuretics (water pills), and chronic decreased kidney function (kidney disease).
