Question 28 Explanation:
Diuretics such as furosemide may deplete serum potassium, leading to hypokalemia. When the client is also taking digoxin, the subsequent hypokalemia may potentiate the action of digoxin, placing the client at risk for digoxin toxicity. Diuretic therapy may lead to the loss of other electrolytes such as sodium, but the loss of potassium in association with digoxin therapy is most important. Hypocalcemia is usually associated with inadequate vitamin D intake or synthesis, renal failure, or use of drugs, such as aminoglycosides and corticosteroids. Hypomagnesemia generally is associated with poor nutrition, alcoholism, and excessive GI or renal losses, not diuretic therapy.

Which electrolyte would the nurse identify as the major electrolyte responsible for determining the concentration of the intracellular fluid?

The major cation in the intracellular fluid is potassium. These electrolytes play an important role in maintaining homeostasis.

Which of the following electrolytes are the main determinants of extracellular volume?

Sodium provides the osmotic skeleton for the ECF, and the sodium content is the single most important determinant of ECF volume (Rose, 1984). Sodium deficits result in decreases in ECF volume, whereas sodium excess is most often associated with water retention and results in edema (McKeown, 1986; Rose, 1984).

What are the major electrolytes?

Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes.

What are intra and extracellular electrolytes?

Total body water. Intracellular water: Fluid inside cells. Extracellular water: Fluid is outside the cells i.e. within interstitial tissues surrounding cells, blood plasma, and lymph. The electrolytes are necessary for maintaining osmotic pressure and electro neutrality (equal number of cations and anions).
