The client experiencing abdominal distention and severe vomiting has just had a nasogastric (NG) tube inserted. When teaching this client, which rationale for the use of the NG tube should the nurse include?

A. A healthy stoma should appear moist and shiny, indicating adequate blood supply and hydration of the tissue. Dryness or dullness of the stoma may indicate poor blood flow or dehydration and should be further evaluated.
B. A healthy stoma typically appears deep pink to red in color, indicating good tissue perfusion. Pallor or cyanosis of the stoma may indicate inadequate blood supply and should be assessed promptly.
C. The skin around the stoma, known as the peristomal skin, should be intact, without signs of irritation, redness, or tenderness. Irritation or breakdown of the peristomal skin can occur due to leakage of stool or irritation from ostomy appliances and should be addressed promptly to prevent skin complications.
D. A flat abdomen suggests normal abdominal contour without distention or bulging. Distention or bulging of the abdomen may indicate underlying issues such as bowel obstruction, gas accumulation, or fluid retention and should be assessed further.

E. Bowel sounds are indicative of gastrointestinal motility and function. Normal bowel sounds are present and audible in healthy individuals and are characterized by 8 to 10 clicks or gurgles per minute. Absence or abnormal bowel sounds may indicate bowel obstruction, ileus, or other gastrointestinal disorders and should be assessed further.

A. These are indicative of inflammation within the vein, which is characteristic of phlebitis. Warmth is a common sign of inflammation, and the palpable cord suggests that the vein may be hardened or cord- like due to inflammation and irritation.
B. While this could indicate some form of vascular injury or extravasation, it is not a typical presentation of phlebitis. Phlebitis involves inflammation of the vein, which may cause redness, warmth, and tenderness along the course of the vein, but it typically does not manifest as a raised ecchymotic (bruised) area.
C. Swelling occurs due to inflammation within the vein, and tenderness is often present as a result of the irritation and inflammation. These symptoms are commonly observed in cases of phlebitis but are not specific.
D. These are not typical signs of phlebitis. Blanching (turning white) and coolness of the skin may suggest reduced blood flow to the area, which could occur in cases of ischemia or thrombosis but are not characteristic of phlebitis.
