- Which of the following statements characterizes cardiogenic
shock?
- Increased stroke volume in face of decreasing cardiac output
- The heart fails to function as a pump
- Increasing stroke volume in face of increased cardiac output
- Cardiogenic shock is the only result of a massive myocardial infarction
Homework Answers
Ans) d.Cardiogenic shock is the only result of a massive myocardial infarction.
Explaination:
- Myocardial pathology Cardiogenic shock is characterized by systolic and diastolic dysfunction leading to end organ. Decreased coronary perfusion pressure and cardiac output as well as increased myocardial oxygen demand play a role in the vicious cycle that leads to cardiogenic shock and potentially death.

10-In distributive shock, total blood volume is (increased, decreased, normal) but venous return (increases, decreases) as blood vessels (constrict, dilate). This type of shock is caused by (increased, decreased) SNS activity or from release of vaso(constrictor, dilator) chemicals 11- Which of the following represent types of distributive shock? (anaphylactic, hypovolemic, obstructive, cardiogenic, neurogenic, septic) 12- brain injury damages sympathetic nerves common distributive shock with 40% mortality MI leading to congestive heart failure cardiac tamponade a) septic b) neurogenic c) cardiogenic...

Hypovolemic Shock (Compensatory Stage): 1. Compensatory stage of shock in which body maintains cardiac output, despite loss of blood volume (decrease in stroke volume) 2. Decrease in SV precipitates i...
Hypovolemic Shock (Compensatory Stage): 1. Compensatory stage of shock in which body maintains cardiac output, despite loss of blood volume (decrease in stroke volume) 2. Decrease in SV precipitates increase in HR 3. Signs include narrowing PP, due to increased diastolic pressure a. Vascular tone constricts to shunt blood to vital organs, results in increased diastolic pressure 4. Key symptom of shock is increase in thirst, due to RAAS activation. a. Fun fact: Don’t give water to people in shock;...

5. Consider the following equation: Stroke volume = cardiac output / heart rate If a heart fills up to 200ml of blood before contraction, and leaves 50ml in the heart after contraction, what would be the stroke volume? If the heart rate is 80 beats per minute, what would the calculated cardiac output? If the total peripheral resistance increases, what is likely to happen to the stroke volume? (Please address all three questions and include units to receive full credit.)...
