CARDIOGENIC SHOCK - QUIZ QUESTIONS


Myocardial infarction

A heart attack is the layman's term for a (MI) myocardial infarction.    
It is caused by  a lack of blood supply to the heart muscle. A blood clot
 or plaque, may obstruct the flow of blood. This typically occurs in the   
patient with CAD ( coronary artery disease). Symptoms include:            
              chest pain which may radiate to the shoulder and jaw, pressure or                         
                                            tightness in the chest, anxiety, nausea, vomiting and shortness of breath.                                                                             
                               


Cardiogenic shock

The left ventricle receives its blood supply from the LAD ( left anterior descending)
artery. If the flow of blood to the left ventricle is obstructed by a clot or plaque, part 
of the heart muscle may die. This lack of blood flow to the left ventricle causes pump
failure. Cardiogenic shock may result from pump failure.  
                                            
           Signs of cardiogenic shock include: 

                      - cool clammy skin due to poor perfusion   
  -  respiratory compromise   
                                         - hypotension, as the heart loses its ability to pump enough blood                                                            - altered mental status, oliguria  ( a decrease in urinary output)                    
                                               
                        Watch the video: Cardiogenic shock                                        

                                                                                                                                                     
                                  
Management of Cardiogenic Shock                                               
                                               
       ICU care will be necessary for the patient in cardiogenic shock. Mechanical ventilation
       is usually needed to supply adequate oxygenation. Some drugs  that may be used are:   
             TPA to dissolve blood clots, Heparin ( an anticoagulant), Dobutamine ( for cardiac output)
and Dopamine to improve blood pressure.  Enjoy watching the videos:

Quiz questions:
1) What is the layman's term for a myocardial infarction?
          2) What are some of the symptoms of a myocardial infarction?
3) What causes cardiogenic shock?                                    
               4) What are some of the signs of the patient in cardiogenic shock?
        5) How is cardiogenic shock managed?                                     


Clinical picture of the patient in Cardiogenic Shock

     Cool, clammy skin, hypotension, oliguria, altered mental status,
and respiratory compromise, decrease in O2 saturation.
EKG changes will also be detected.

HELPFUL INFORMATION ABOUT AN AORTIC ABDOMINAL ANEURYSM

Image
  Scenario : Mr. S is an elderly male who has a longstanding history of hypertension. He suddenly develops throbbing  pain in the abdomen. He notified his doctor and was admitted to the hospital for tests. A CAT scan would reveal an  Abdominal Aortic Aneurysm. Surgical intervention for AAA was done emergently. Following surgery, Mr.S was transferred to the ICU  for a higher level of care. During his stay, his vital  signs, neurological, cardiac and respiratory status   would all be monitored.

CHEST PAIN ASSESSMENT AND EKG - QUIZ

Image
                       Chest pain assessment Chest pain is a very common complaint . It may occur anywhere and anytime, even at rest. It may be related to stress or actual damage to the heart. A patient having a heart attack , may very readily complain of chest pain. Helpful hints : If the patient in your care is complaining of chest pain,   immediate action should be taken to assess the pain. Chest pain may be sharp, severe and stabbing. It may also feel like pressure in the chest or  Like a pair of hands squeezing the chest.  It is important to do a pain assessment on a scale of 1-10 and document results. It is also of note to ask the patient to describe the character  and duration of the pain. Always remember to document all interventions. Follow your Institution's policies, procedures and MD orders for chest pain. Do you know your heart Simple EKG interpretation: The EKG (Electrocardiogram) is a noninv...
