Answer to Question 1

ANS: D
An echocardiogram is a noninvasive test that can show the size and location of a heart defect. An electrocardiogram (ECG) provides visualization of the heart's electrical activity. Direct pressure measurements are obtained with cardiac catheterization. More specific information can be obtained about heart defects via a magnetic resonance angiogram or computed tomographic angiogram.

Answer to Question 2

ANS: C
Clubbing of the fingernails is associated with chronically low oxygenation. A PaO2 of 72 mm Hg is low. The other values are normal.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
