NRS 410 Week 1 QUIZ. Grand Canyon University.anatomy
Oxygen saturation is likely to be lowest when an asthmatic with a diagnosis of pneumonia
... [Show More] is
Positioned
:
C) Lying on the right side
D) Lying supine with the head of the bed flat
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.

Which of the following is true of the biological functions of testosterone?
D) Testosterone is needed for development of male secondary sexual characteristics.
D) Testosterone is needed for development of male secondary sexual characteristics.
Testosterone is needed for development of male secondary sexual
characteristics.

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.

anatomy
Which of the following is true of the biological functions of estrone?
C) Estrone is required for proper development of female secondary sexual characteristics.
D) Estrone affects only the reproductive organs.
Estrone is required for proper development of female secondary sexual characteristics.

anatomy
Ausculation of the chest reveals bilateral fine crackles in the bases bilaterally, indicating:
B) Left-sided heart failure
B) Left-sided heart failure
This occurs because valve dysfunction creates abnormally high pressures in the cardiac chambers and in the pulmonary capillary bed. Isolated right-sided heart failure would not
cause pulmonary congestion; it would present as edema in the systemic circulation. [Show Less]
