Answer to Question 1

ANS: D
Anaphylactic shock results from extreme allergy or hypersensitivity to a foreign substance. Neurogenic shock results from loss of neuronal control, such as the interruption of neuronal transmission that occurs from a spinal cord injury. Cardiogenic shock is decreased cardiac output. Hypovolemic shock is a reduction in the size of the vascular compartment, decreasing blood pressure, and low central venous pressure.

Answer to Question 2

ANS: B
Blood loss is the most frequent cause of hypovolemic shock in children. Sepsis causes septic shock, which is overwhelming sepsis and circulating bacterial toxins. Anaphylactic shock results from extreme allergy or hypersensitivity to a foreign substance. Congenital heart disease contributes to hypervolemia, not hypovolemia.
