Question

Quizplus · Accepted Answer

Tube feedings are associated with hypernatremia as a result of intake of highly concentrated solution that causes the kidneys to excrete extra water to remove the solute load.Absorption of excessive water from daily tap water enemas would cause hyponatremia.Uncontrolled secretion of ADH causes renal retention of water that leads to hyponatremia.An IV solution of 0.9% NaCl (normal saline)is isotonic.
