A nurse is administering an intermittent enteral feeding through a client's NG tube. During the instillation, the client reports abdominal cramping and nausea. Which of the following actions should the nurse take?

A. Right upper quadrant is correct. A colostomy placed in the ascending colon is typically located in the right upper quadrant of the abdomen. The ascending colon runs along the right side of the abdomen, so the stoma will be located in that region.

B. Left lower quadrant is incorrect. The left lower quadrant is typically where the descending colon or sigmoid colon are located, so a colostomy placed here would be for those regions, not the ascending colon.

C. Left upper quadrant is incorrect. The left upper quadrant contains parts of the stomach, spleen, and pancreas, but not the ascending colon. A colostomy in the ascending colon would not be located here.

A. An anaphylactic reaction is correct. Symptoms such as urticaria (hives) and wheezing indicate a severe allergic reaction, which can progress to anaphylaxis. This reaction is caused by a hypersensitivity to plasma proteins in the transfused blood and requires immediate intervention, including stopping the transfusion and administering epinephrine.

B. An acute hemolytic reaction is incorrect. This reaction occurs when the recipient's immune system attacks incompatible donor red blood cells, leading to symptoms such as fever, chills, flank pain, hypotension, and hemoglobinuria. Urticaria and wheezing are not characteristic symptoms of this reaction.

C. A febrile reaction is incorrect. Febrile reactions are the most common type of transfusion reaction and are typically characterized by fever, chills, and headache, rather than urticaria or wheezing.

D. Circulatory overload is incorrect. This reaction occurs when too much fluid is infused too quickly, leading to dyspnea, hypertension, and pulmonary edema. While respiratory distress can occur, it is not accompanied by urticaria, which is specific to an allergic reaction.
