What are nursing interventions for hypovolemic shock?
-oxygen therapy (maintain 90-96%)

-echocardiogram (structural heart disease, cardiac function and contractility)
-ABG's
-cardiac biomarkers (troponin, BNP)
-elevated lactate levels
-stress testing (identifies ischemia)
-coronary angiography (visualizes blocked arteries)
What are some nursing interventions for anaphylactic shock?
-epinephrine (first line treatment)
-maintain airway
-call for help (rapid response)
-oxygen therapy
-IV fluid resuscitation (normal saline, LR)
-assess VS, LOC, cardiac rhythm, skin, urine output
-antihistamines (help with itching)
-corticosteroids (prevents biphasic reactions--can occur hours to days later, reduce inflammation)
What are some causes of neurogenic shock?
-spinal cord injury (most common- above T6)
