A client is suspected to have diverticulosis without symptoms of diverticulitis. Which diagnostic test should the nurse prepare the client to undergo?

Choice A reason: Securing the drain to the client's bed sheet is not the best action for the nurse to take. This could cause the drain to be pulled or dislodged if the client moves or changes position. The nurse should secure the drain to the client's gown or abdominal binder, using a safety pin or a clip.

Choice B reason: Removing the JP drain when the drainage has ceased, covering the opening with sterile gauze, is not the correct action for the nurse to take. The nurse should not remove the drain without a physician's order, as this could cause complications such as infection, bleeding, or bile leakage. The nurse should monitor the amount and color of the drainage, and report any changes to the physician.

Choice C reason: Expelling the air from the JP bulb after emptying to re-establish suction is the correct action for the nurse to take. The JP drain works by creating a negative pressure that draws fluid from the surgical site. The nurse should empty the bulb when it is half full, and squeeze it until it collapses before closing the plug. This ensures that the suction is maintained and prevents the fluid from flowing back into the drain.

Choice D reason: Measuring the drainage every hour for the first 8 hr postoperative is not the correct action for the nurse to take. This is too frequent and unnecessary, as the drainage is expected to decrease over time. The nurse should measure the drainage every 8 to 12 hr, or as ordered by the physician, and record the volume and color. The nurse should also report any signs of infection, such as fever, pain, or foul odor.

Choice A reason: This is a correct finding for a client with an obstruction of the common bile duct. Fatty stools are caused by the reduced or absent flow of bile into the intestine, which impairs the digestion and absorption of fats.

Choice B reason: This is not a correct finding for a client with an obstruction of the common bile duct. Tenderness in the left upper abdomen may indicate a problem with the spleen, the stomach, or the pancreas, but not the bile duct.

Choice C reason: This is not a correct finding for a client with an obstruction of the common bile duct. Ecchymosis of the extremities is a bruising of the skin due to bleeding under the surface. It may be caused by trauma, medication, or bleeding disorders, but not by bile duct obstruction.

Choice D reason: This is not a correct finding for a client with an obstruction of the common bile duct. Pale-colored urine is a sign of dilute or low concentration of urine, which may be caused by excessive fluid intake, diabetes insipidus, or kidney failure, but not by bile duct obstruction.
