60 cm above the patient good vision but also not lead to excessive systemic fluid absorption
47
TUR syndrome: If profound CNS symptoms are noted, judicious administration of ______ should be instituted, and formulas exist to help guide this resuscitation as overly rapid correction of hyponatremia may lead to a ______.
