A 78-year-old man is being evaluated in the geriatric clinic. His daughter reports that he has been very forgetful lately, and she is concerned that he might be "senile."
The advanced practice nurse administers the clock-drawing test and the patient draws a distorted circular shape and places the numbers all on one side of the shape. Based on his performance, the nurse concludes that the patient:
a. probably has Alzheimer's disease.
b. needs further evaluation.
c. probably has delirium.
d. needs a functional status assessment.
ANS: B
Cognitively intact persons rarely produce errors on the clock-drawing test, such as grossly dis-torted contour. A low score on the clock-drawing test requires further evaluation. Alzheimer's disease is not a diagnosis using a mental status assessment tool. It is definitively diagnosed with a brain biopsy. The clock-drawing test does not assess for delirium. A low score on the clock-drawing test does not necessarily warrant a functional status assessment.
