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 after 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: C
Children who are vomiting should be given ORS at frequent intervals and in small amounts. Intravenous fluids are not indicated for mild dehydration. Carbonated beverages are high in carbohydrates and are not recommended for the treatment of diarrhea and vomiting. The child is not kept NPO because this would cause additional fluid losses.
