NRS 410 Week 2 QUIZ With Answers And Rationale. Grand Canyon University.anatomy Backward effects of left-sided heart failure include: A) Pulmonary congestion A) Pulmonary congestion Deoxygenated b... lood from the right ventricle flows through the right and left pulmonary arteries to the right and left lung. After entering the lungs, the branches subdivide, finally emerging as capillaries which surround the alveoli and release the carbon dioxide in exchange for oxygen. The capillaries unite gradually and assume the characteristics of veins. These veins join to form the pulmonary veins, which return the oxygenated blood to the left atrium. Backflow of blood through the left atrium result in left-sided heart failure. 2 anatomy Oxygen saturation is likely to be lowest when an asthmatic with a diagnosis of pneumonia is positioned: C) Lying on the right side C) Lying on the right side Ventilation and perfusion distribute to the dependent lung fields. In a patient with pneumonia in the right lung, positioning with the right lung down would send more blood flow to the consolidated, nonventilated areas of the lung and produce a worse V/Q mismatch, which would decrease oxygen diffusion into the blood and produce a lower arterial oxygen saturation. 3 anatomy In performing a physical assessment, the nurse notes the patient has a “barrel― configuration to the chest. This is a consequence of: D) Increased residual lung volume D) Increased residual lung volume Emphysema typically produces a barrel –shaped chest with an increased anterior-posterior dimension. This is a result of loss of lung parenchyma resulting in reduced elastic recoil and increased residual volume and functional residual capacity. 4 anatomy Which of the following is true of the biological functions of testosterone?
