The Home Health Nurse Assesses an 80-Year-Old Who Has Fallen

The nurse discovers that the patient uses a cane for ambulation stability, drinks up to 6 cups of coffee a day, has altered depth perception because of cataracts, and has recently carpeted her home with a smooth tight weave carpet. The nurse suspects the cause of her recent falls to be the:

A) use of the cane.
B) new carpet.
