Answer to Question 1
D
A colonoscopy provides direct visualization of the rectum, colon, entire large intestine, and distal small bowel. A sigmoidoscopy allows direct visualization of the anal canal, rectum, and sigmoid colon, but not of the entire large intestine. Many patients and providers choose a colonoscopy for cancer screening, as this procedure provides better visualization of the colon. A barium enema is a radiological examination of the rectum, colon, and small bowel; however, this test does not provide direct visualization. Instead, it requires the use of barium and views these organ structures via x-ray. An ultrasound detects tissue abnormalities such as masses, cysts, edema, or stones, usually through the use of a transducer that is moved externally across the skin surface of the abdomen; it is not direct visualization.
Answer to Question 2
B
Active participation in a weight-bearing and weight-lifting program demonstrates not only understanding of the treatment of osteoporosis but also commitment to an action plan to reduce bone loss that accompanies osteoporosis. Calcium supplementation is also part of the treatment for osteoporosis. However, high phosphorous intake lowers calcium levels and would not be appropriate for a client with osteoporosis. Restricting weight-bearing activity to a wheelchair will actually lower bone density. Although follow-up care is appropriate for a client with osteoporosis, it does not indicate commitment to a daily treatment plan.
