Which of the following conditions can lead to cell lyses if not properly monitored? Hypotonicity Hypertonicity Isotonicity None of the options are correct {Ans: Hypotonicity; When a cell is exposed to such hypotonic conditions, there is net water movement into the cell. Cells without walls will swell and may burst (lyse) if excess water is not removed from the cell They have lower concentrations of solute. This can cause fluids to shift out of the vascular spaces and into the interstitial spaces and into the cells.}Isotonic fluids cause shifting of water from the extracellular space to the intracellular space. False True {Ans: False "No fluid shift"}Which of the following is not a hypertonic fluid? 3% Saline 10% Dextrose in Water (D10W) Lactated Ringer's {Ans: Lactated Ringer's (Isotonic)}When administering a hypertonic solution the nurse should closely watch for?
