Final answer:
Smoking is a risk factor associated with both kidney cancer and bladder cancer in patients with cancer of the urinary system.
Step-by-step explanation:
The nurse recognizes smoking as a risk factor associated with both kidney cancer and bladder cancer in patients with cancer of the urinary system. Smokers are at an increased risk of developing chronic kidney disease and smoking hastens the progression of kidney damage in people with diabetes.
Smoking also increases the risk of influenza and other infectious diseases due to damage to the respiratory and immune system. Therefore, it is important for the nurse to inquire about the patient's smoking history when obtaining a nursing history from a patient with cancer of the urinary system.
