Answer to Question 1

Answer: B
The manifestations of acute and chronic respiratory acidosis differ. The client with chronic respiratory acidosis will demonstrate daytime sleepiness. The client with acute respiratory acidosis may demonstrate warm, flushed skin, irritability, and blurred vision from the acute decline in oxygenation.

Answer to Question 2

Answer: C
Colorectal cancer is asymptomatic in the early stages. Screening tools such as annual fecal occult blood testing and colonoscopy performed every 5-10 years can detect the cancer when it is still in the curable stage. The risk of colorectal cancer rises with age and it is the most common cancer after the age of 65. Carcinogenic embryonic antigen (CEA) is not considered a diagnostic test but is used as a tumor marker to follow and manage the disease in clients diagnosed with the disease. The incidence of colorectal cancer is increased in clients with a history of ulcerative colitis, and these clients need diligent screening.
