Question

Quizplus · Accepted Answer

Dextran is a large carbohydrate that cannot cross plasma membranes easily, making it suitable for administration to patients suffering from blood loss as a volume expander. Saline, salt solution, and isotonic saline are all solutions that can help replenish fluids, but they do not provide the same level of osmotic pressure or volume expansion as dextran. Glucose is a carbohydrate that can be used to replenish energy stores, but it can cross plasma membranes readily and is not as effective as a volume expander.
