Answer to Question 1
C
Inspection is the visual examination of body parts or areas. An experienced nurse learns to make multiple observations, almost simultaneously, while becoming very perceptive of abnormalities. Palpation uses the sense of touch. Percussion involves tapping the body with the fingertips to evaluate the size, borders, and consistency of body organs and to discover fluid in body cavities. Auscultation is listening with a stethoscope to sounds produced by the body.
Answer to Question 2
A
Immediately after a fecal surgical diversion, it is necessary to place a pouch over the newly created stoma to contain effluent when the stoma begins to function. The pouch will keep the patient clean and dry, will protect the skin from drainage, and will provide a barrier against odor. Dressings would obstruct the opening and would become saturated with fecal material. Preparing multiple pouches in advance would be counterproductive; in the immediate postoperative period, the stoma may be edematous and the abdomen distended. These symptoms eventually resolve, but during this time, it will be necessary to revise the pouching system to meet the changing size of the stoma and the changes in body contours.
