Type of shock associated with spinal cord injury is __________. 20sec

Hypovolemic

Neurogenic Cardiogenic Distributive How many minutes can the body go without oxygen before brain cells begin to die?

2 minutes 60 seconds 4 minutes 5 minutes 20sec What causes the cool, damp skin of patients in shock? 20sec

Decreasing levels of CO2

Constriction of peripheral blood vessels due to shunting of blood Action of the ADH released in shock Activation of the baroreceptors

When should the nurse be alerted that the patient's renal function is decreasing? 20sec

UOP less than 0.5 mL/kg/h UOP less than 1.5 mL/kg/h UOP less than 0.2 mL/kg/h UOP less than 0.5 mL/kg/d What do anaphylactic shock, septic shock, and neurogenic shock have in common? 20sec

Heart failure Allergic reaction

Widespread vasodilation Rapid fluid loss Distributive shock can be seen in all but one of the following: 20sec

Bee sting Bacterial infection

Fluid loss Vasodilation seen in a spinal cord injury

What would a nurse expect to see in the patient with shock in end-organ dysfunction. 20sec

Thready pulse and irregular respirations with increased blood pressure Bounding pulse, shallow respirations, and increased blood pressure Bounding pulse, decreased respirations, and decreased blood pressure

Thready pulse and deep respirations with decreased blood pressure

The three stages of shock in order are: shock, pre-shock, and end-organ dysfunction 20sec

True

False What is the purpose of hypothermic devices for treatment of shock?

To provide compression to the lower extremities to stop internal bleeding To keep the patient warm for better survival

To improve neurologic recovery Applies pressure during systole and relaxes during diastole

Which type of blood can be administered to all patients no matter what blood type?

A AB

O B c What is a possible complication of thrombophlebitis? 20sec

Cardiac tamponade Pneumonia

Pulmonary embolism Pulmonary edema

Which of the following findings should the nurse expect in a patient with Hypovolemic shock? 20sec

Oliguria, low urine production Purpura, skin hemorrhages Hypertension, elevated BP Bradypnea, slow respirations In Systemic inflammatory response syndrome (SIRS) prompt and aggressive treatment is necessary to support the failing organs. 20sec

True False In evaluating the brain of a patient in cardiogenic shock what pulse would be most appropriate to check?

20sec

Radial

Carotid Femoral Pedal An intra-aortic balloon pump (IABP) is a type of therapeutic device. It helps your heart pump more blood. You may need it if your heart is unable to pump enough blood for your body. The IABP consists of a thin, flexible tube called a catheter. Attached to the tip of the catheter is a long balloon.

The balloon of the IABP is inserted into the thoracic aorta

diastole deflating before systole

inflating during

What does lactic acid build up, cause?

• Lactic acid causes tissue acidosis and subsequent organ dysfunction When does shock officially begin? Shock begins when the cardiovascular system fails

• What are the four vital components? Name the types of shock…

• • • •

Hypovolemic Cardiogenic Obstructive Distributive • Anaphylactic shock

• Septic shock • Neurogenic shock Sepsis is a systemic inflammatory response to a documented or suspected infection; sepsis can progress to septic shock. Very common in facilities with patients that have indwelling catheters, nurses mistake age confusion with s/s sepsis

During Shock lactic acid builds up causing?

• Acid-base balance metabolic acidosis Cardiogenic shock is caused by a decrease in ? Cardiac output •

Medications would be the primary means for treating this type of shock

• Cardiogenic shock is primarily treated with medications to resolve the primary issue.

• During the end organ dysfunction phase, respirations are deep and rapid, why? (last ditch effort to do what? ) A last ditch effort to blow off CO2 •

• the stages of shock are compensatory, progressive, refractory which is no longer used, • we now say pre shock, shock and end organ

dysfunction

• For shock, what would be a primary nursing diagnosis? A. decreased urine output r/t hypovolemia B. lack of education about circulation

C. circulatory compromise related to hypovolemia • D. circulatory failure related to hypertension

Common sign regardless of the type of shock is cool and clammy skin, cyanotic nail beds,, why?

The body is shunting blood from less necessary systems (like the skin) and diverting it to critical systems • A patient in the progressive stage of shock would be decompensated and have low bp, deep respirations with crackles (fluid) dry mouth and decreased urine output • Decreasing anxiety is essential with these patients, why? Shock already raises HR and Respiratory rate and anxiety only makes it worse Patients that have SIRS have damage to the endothelium of blood vessels and a hypermetabolic state, this depletes carbohydrate, fats and protein stores so these patients have a tendency to be put on parenteral feedings.

FIRST AID FOR SHOCK OUTSIDE THE MEDICAL FACILITY First intervention is to position the patient supine , Trendelenburg with the feet up, head down increases cerebral blood flow

The type of shock that is caused by physical impairment is __________. Hypovolemic Cardiogenic

Obstructive Septic

Which of the following is a true statement about the effects of shock on body systems and functions? A. Metabolic alkalosis B. Increased glomerular filtration C. Absorption of catecholamines and mineralocorticoids

D. Decreased peristalsis •Once stabilized, the patient should be allowed frequent rest periods due to the lack of decreased output

• Why would heparin be used as a pharmacologic therapy for shock? • Heparin causes the activation of both inflammation and coagulation which may improve the outcome in sepsis. Apart from the well-known anticoagulant effects of heparin, it also possesses various immunomodulatory properties and protects glycocalyx from shedding. Hence, heparin seems to be such an agent.

After the administration of epinephrine, post nursing interventions need to focus on HR BP Resp, and edema,,, why The Patient must be monitored to ensure the epi wasn’t too much, too little or wearing off while there is still a problem

In Systemic inflammatory response syndrome

(Sirs)

Patients that have SIRS have damage to the endothelium of blood vessels and a hypermetabolic state, this depletes carbohydrate, fats and protein stores so these patients have a tendency to be put on parenteral feedings. • Elevated Temp, HR, elevated wbc elevated respirations are the main criteria for SIRS , 2
