Oxygen saturation is likely to be lowest when an asthmatic with a diagnosis of pneumonia is
QUESTION positioned:
CORRECT C) Lying on the right side
ANSWER
YOUR ANSWER 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
RATIONALE 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.

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

QUESTION configuration to the chest. This is a consequence of:
CORRECT D) Increased residual lung volume
ANSWER
YOUR ANSWER 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
RATIONALE increased residual volume and functional residual capacity.
