When should vasopressors be administered during the management of septic shock? If the individual develops pulmonary edema Vasopressors are never used for septic shock. Always indicated as soon as IV access is obtained If the individual is severely hypotensive despite proper fluid management Uninterrupted chest compressions are critical when treating individuals in cardiac arrest. You should only interrupt chest compressions to do the following: Evaluate cardiac rhythm and administer shocks. Administer medications. Place an endotracheal tube. Obtain central IV access...
