Question 1 1 out of 1 points Fresh frozen plasma (FFP) is administered to replace: Selected Answer: clotting factors. Answers: clotting factors. erythrocyte s. leukocytes. platelets. Response Feedback: Fresh frozen plasma is administered to replace all clotting factors except platelets. Platelets are given rapidly to help control bleeding caused by low platelet counts. Question 2 1 out of 1 points In distributive shock, the major physiological problem causing the shock is: Selected Answer: vasodilation and relative hypovolemia. Answers: blood loss and actual hypovolemia. decreased cardiac output. third spacing of fluids into peritoneal space. vasodilation and relative hypovolemia. Response Feedback : Distributive shock presents with widespread vasodilation and decreased systemic vascular resistance that results in a relative hypovolemia. Blood loss is associated with hypovolemic shock. Decreased cardiac output is a primary cause of cardiogenic shock. Primary internal sequestration of fluids that causes internal fluid loss is associated with hypovolemic shock. Question 3 1 out of 1 points A primary goal in all shock states is to: Selected

Answer: maintain adequate tissue perfusion. Answers: ensure adequate cellular hydration. maintain adequate tissue perfusion. prevent third spacing of fluids. support mechanical ventilation. Response Feedback: Care of a patient in shock is directed toward correcting or reversing the altered circulatory component and reversing tissue hypoxia. Restoring circulating intravascular volume is the priority in improving tissue perfusion and oxygen delivery. Question 4 1 out of 1 points The majority of cases of cardiogenic shock are caused by: Selected Answer: acute myocardial infarction. Answers: acute myocardial infarction. myocardial depression in sepsis. pulmonary embolism. significant hypovolemia. Response Feedback : The most common cause of cardiogenic shock is an extensive left ventricular myocardial infarction. Myocardial depression in sepsis is a secondary problem associated with the acidosis/anaerobic metabolism of septic shock. Pulmonary embolism is a cause of obstructive shock. Fluid loss is the major cause of hypovolemic shock. Question 5 1 out of 1 points When neurogenic shock occurs, interruption in sympathetic nerve impulses causes: Selected Answer: vasodilation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
