|
Term
| What is the most common cause of shock |
|
Definition
|
|
Term
|
Definition
| Release of endotoxins by bacteria which act on nerves in vascular spaces in the periphery, causing vascular pooling, reduced venous return and decreased cardiac output and resulting in poor systemic perfusion |
|
|
Term

Definition
| Quick restoration of cardiac output and tissue perfusion |
|
|
Term
| what intervention is used to restore cardiac output when hypovolemic shock exists? |
|
Definition
| Rapid infusion of volume expanding fluids |
|
|
Term
| It is important to differentiate btwo hypovolemic and cardiogenic shock. How might the nurse determine the existence of cardiogenic shock? |
|
Definition
| History of MI with lt ventricular failur or possible cardiomyopathy with symptoms of pulmonary edema |
|
|
Term
| If a client is in cardiogenic shock, what might result from administration of volume-expanding fluids, and what intervention can the nurse expect to perform in the event of such an occurences? |
|
Definition
| Pulmonary edema; admin cardiotonic drugs such as digitalis preps |
|
|
Term
| List five assessment findings that occur in most shock victims |

|
Term
| What is the normal CVP for an adult? |
|
Definition

Definition
|
|
Term
| name four nursing interventions to prevent injury in clients with DIC |
|
Definition
| Gently provide oral care with mouth swabs. Minimize needle sticks and use the smallest gauge needle possible when injections are necessary. Eliminate pressure by turning the client frequently. Minimize the number of BP measurements take by cuff. Use gentle sunction to prevent trauma to mucosa apply pressure to any oozing site |
