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)

Clinical picture of the patient in Cardiogenic Shock ( above)

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

       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:

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. Please click on the links for more learning: Hemodynamic Monitoring Info for the layperson Scenario : Mr.S had a repair of an Abdominal Aortic Aneurysm done. He  will be cared for and  closely monitored  in the ICU. Please click on the link below, for more information. Mr. S in the ICU.    What is an aneurysm? An aneurysm is a ballooning or bulging in a  blood  vessel. Aneurysms may occur in the brain or the abdomen  (the aort...

AN OVERVIEW OF ANASARCA - QUIZ QUESTIONS

Image
The image above shows the clinical picture of the patient with Anasarca. Anasarca and its causes Anasarca, which is also known as generalised edema, may be caused by a number of conditions. These include: - Heart, renal or liver failure - Low albumin (hypoalbuminemia), burns - Corticosteroids and more The treatment is directed at the cause: - The patient in renal failure may require hemodialysis. - Liver failure may call for long and aggressive treatment.  Fluid restriction, diuretics, dietary changes (like sodium restriction),  and daily weights may be ordered by the doctor. - The patient with hypoalbuminemia will need IV albumin replacements. Lab values are also necessary, to monitor an  improvement in the albumin levels or sodium levels. Also enjoy watching the video: Sessions 46- Assessment QUIZ QUESTIONS 1) What is anasarca also known as? 2) Name some of the causes? 3) How is this condition treated? 4) What is hemodialysis?

LIVER FAILURE AND PARACENTESIS / POTENTIAL PROBLEMS/ CARE PLANNING

Image
  Paracentesis In the image above , a patient is being examined by his doctor. He has an enlarged abdomen due to liver  failure. He is also experiencing shortness of breath . The patient in  liver   failure, may experience difficulty breathing. This is caused by an accumulation of peritoneal fluid in the abdominal   cavity. Paracentesis is done to remove excess fluid and make  breathing easier. The Care Plan would reflect the potential problems associated with this condition. This would include: - Respiratory problems related to ascites. -  Skin breakdown  related to  anasarca . - M ental confusion  related to liver toxins. -Decrease in  urinary output  related to liver failure. Learn more about : P otential problems and   Care planning and The Digestive System Here are some diagnostic tests that are done frequently. Follow the links below: 1.  Chest X ray 2.  CAT scan 3.  EKG 4.  MRI scan 5....
