Dehydration in Children
Dehydration in Children ( 29 Questions)
The nurse is preparing to start an intravenous (IV) infusion.
Which of the following IV fluids is the most appropriate for this client?
Normal saline (0.9% NaCl) is the most appropriate choice for a client with burns and hypovolemia. This isotonic solution helps to restore intravascular volume and replace lost fluids. It contains sodium chloride in a concentration similar to that of the body's extracellular fluid, making it effective for rehydration and replenishing electrolytes in hypovolemic patients.
Half normal saline (0.45% NaCl) is a hypotonic solution with a lower sodium concentration than the body's extracellular fluid. It is not the best choice for treating hypovolemia and burns because it may not effectively expand intravascular volume and may cause cellular swelling.
Lactated Ringer's is an isotonic solution, but it contains additional electrolytes and lactate. While it can be suitable for some fluid replacement needs, normal saline is preferred for burn patients because it has a simpler composition and is effective for volume resuscitation in cases of hypovolemia.
D5W (5% dextrose in water) is a solution that primarily provides dextrose for energy, not suitable for hypovolemia and burns. It can cause dilutional hyponatremia if used as the primary fluid in hypovolemic patients.
Normal saline (0.9% NaCl).
Choice A rationale:
Normal saline (0.9% NaCl) is the most appropriate choice for a client with burns and hypovolemia.
This isotonic solution helps to restore intravascular volume and replace lost fluids.
It contains sodium chloride in a concentration similar to that of the body's extracellular fluid, making it effective for rehydration and replenishing electrolytes in hypovolemic patients.
Choice B rationale:
Half normal saline (0.45% NaCl) is a hypotonic solution with a lower sodium concentration than the body's extracellular fluid.
It is not the best choice for treating hypovolemia and burns because it may not effectively expand intravascular volume and may cause cellular swelling.
Choice C rationale:
Lactated Ringer's is an isotonic solution, but it contains additional electrolytes and lactate.
While it can be suitable for some fluid replacement needs, normal saline is preferred for burn patients because it has a simpler composition and is effective for volume resuscitation in cases of hypovolemia.
Choice D rationale:
D5W (5% dextrose in water) is a solution that primarily provides dextrose for energy, not suitable for hypovolemia and burns.
It can cause dilutional hyponatremia if used as the primary fluid in hypovolemic patients.
