Final answer:
Heart disease patients should receive a depression assessment first due to the higher risk of depression and its impact on heart disease.
Step-by-step explanation:
The patient who should receive a depression assessment first is a heart disease patient. The American Heart Association has recommended routine depression screening for all heart disease patients, as they have found a clear relationship between heart disease and depression. Heart disease patients have a higher risk of depression, and people with depression are more likely to develop heart disease. Therefore, it is important to assess for depression in heart disease patients to provide appropriate care and support.
