REx-PN
A patient with vomiting, tachycardia, and low urine output may need intravascular volume. The same patient may need less fluid—not more—if crackles and hypoxia appear during the infusion. The bag is not the treatment by itself; the indication, solution, rate, and patient response determine whether IV fluid restores perfusion or causes harm. The RPN’s reasoning sequence is therefore: identify the physiologic problem, assess the risk of fluid harm, verify the prescribed therapy, administer it safely, and reassess whether the patient is improving.
