QUESTION Backward effects of left-sided heart failure include:
CORRECT ANSWER A) Pulmonary congestion
YOUR ANSWER A) Pulmonary congestion
Deoxygenated blood 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.
RATIONALE
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.

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.

configuration to the chest. This is a consequence of:

increased residual volume and functional residual capacity.
