Question
1. A two year old diagnosed with pulmonary semilunar valve stenosis select presented with cyanosis and shortness of breath. He experienced these symptoms because an insufficient amount blood was being circulated to the lungs for oxygenation due to: select hypertrophy and inefectual pumping of the left ventricle. the blood passing through the defective valve directly into the left ventricle. 2. A sixteen year old suffered acute respiratory distress two days after the repair of a complete fracture of his femur bone in the mid-diaphysis region. The respiratory distress was caused by: hypertrophy and ineffectual pumping of the right ventricle. regurgitation of the blood back into the right atrium with each contraction.Explanation / Answer
1. Answer is regurgitation of the blood back into right atrium with each contraction. Pulmonary semilunar valve stenosis is the condition where outflow of blood from righ ventricle obstructed at pulmonary valve. Because of this high pressure on right ventricle circulation does'nt happen properly and blood is pushed back to atrium.
2. Answer is respiratory distress was caused by fragments of yellow bone marrow fat travelling in the blood to the lungs and obstructing lung vessels. Usually there is no problem after a femur fracture repair but in certain cases during fracture some adipose tissues or fat might be released in blood which slowly obstructs lung-capillary tissue during circulation. This is fat embolism syndrome.
