ok so we basically have to learn electrolytes, fluids and acid base balances on our own (we did 2 group activities for this topic and no lecture)
i cannot seem to grasp when you would use the following and why, for what??
1)isotonic solutions 0.9% ns ringer's lactate (?? what is this??)
2) hypotonic 0.45%ns
3) hypertonic d10w?? what is this?? 3 to 5% ns d5ns, d51/2 ns and d5rl?? huh?? can someone help me figure out an easy way to remember how and when these would be used in hyper/hypo states??
thanks!!

The answers for most of your questions are on this chart I put together some time ago: Table of Commonly Used IV Solutions.doc

with this list:
]HYPOTONIC: 0.45% Saline (free water, replace fluid losses, not electrolytes)
]ISOTONIC:
]0.9% Saline] (only solution used with blood products), not for calories, electrolytes or free water, used to replace EC fluid losses (expander)
]Ringer’s Solution]: no Mg2+ no HCO3-, no calories, no free water, to replace
]EC losses, used to expand intravascular volume
]Hartmann’s Solutionn (Lactated Ringer’s):] no Mg2+, no calories, no free water, to treat mild metabolic acidosis, losses from burns and lower GI, not for lactic acidosis
]5% Dextrose in Water: ]170 calories/L, free water, replace water losses, used
]to treat hypernatremia, no electrolytes
]5% Dextrose in 0.225% Saline]: 170 calories/L, free water, Na+, Cl-,
]used to replace hypotonic losses and treat hypernatremia
]HYPERTONIC]:
]10% Dextrose in Water]: 340 calories/L, free water only, no electrolytes
]5% Dextrose in 0.45% Saline]: 170 cal/L, same as 0.45% NaCl
]5% Dextrose in 0.9% Saline]: 170 cal/L, same as 0.9% NaCl
]3.0% Saline]: treat hyponatremia, slow admin (overload, pulm edema)
