Question 2

  2. hypovolemic
  3. cardiogenic
  4. neurogenic

Answer to Question 1

Correct Answer: 1
Distributive shock includes several types of shock that result from widespread vasodilatation and decreased peripheral resistance. As the blood volume does not change, relative hypovolemia results. One example of distributive shock is septic shock. Septic shock is one part of a progressive syndrome called systemic inflammatory response syndrome and is most often the result of gram-negative bacterial infections such as E. coli. Obstructive shock is caused by an obstruction in the heart or great vessels that either impedes venous return or prevents effective cardiac pumping action. Hypovolemic shock occurs with a decrease in circulating blood volume. Anaphylactic shock occurs as the result of a widespread humorally mediated hypersensitivity reaction.

Answer to Question 2

Correct Answer: 1
Obstructive shock is caused by an obstruction in the heart or great vessels that either impedes venous return or prevents effective cardiac pumping action. One cause of obstructive shock is impaired diastolic filling, as seen in a pneumothorax. Hypovolemic shock is seen in patients with a low circulating blood volume. Cardiogenic shock can occur in patients who have experienced a myocardial infarction. Neurogenic shock can occur in patients with spinal cord injuries.
