Answer to Question 1

Correct Answer: 1
Age-related changes in the kidney include the decreased ability to concentrate urine and compensate for increased or decreased salt intake. When this is combined with diminished effectiveness of antidiuretic hormone (ADH) and a reduced thirst response, both age-related, the elderly patient's risk for dehydration increases. Hypoplasia is a congenital renal disorder; renal cysts are hereditary. Decreased glomerular filtration rate (GFR) which is an age-related change in renal function results in reduced clearance of drugs excreted through the kidneys.

Answer to Question 2

Correct Answer: 1, 2, 3
Risk factors for the development of kidney cancer include obesity, age greater than 55, and having a genetic predisposition to the disease. Males are affected more than females by a 2:1 ratio. Bladder calculi are not identified as increasing the risk of kidney cancer.
