Answer to Question 1

B, D, E
The MRI places the patient in a magnetic field and uses radiofrequency signals to determine how hydrogen atoms behave in the field. All metal must be removed, contrast medium may be in-jected, and the patient may have a tingling sensation in the teeth with metal alloy fillings. There is no restriction on food or fluid intake in relation to the test. The test does not expose the patient to radiation.

Answer to Question 2

B, C, E
African Americans have an ethnic tendency to CAD. Taking birth control pills and diabetes are both risk factors for CAD. Older patients are at increased risk for CAD, and a nonsmoking status decreases the likelihood of developing CAD.
