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: Calling the doctor for more antiemetic medication is not the best intervention for the nurse to facilitate. Antiemetics are drugs that prevent or reduce nausea and vomiting, but they may have side effects such as drowsiness, dry mouth, or constipation. The nurse should first try non-pharmacological measures to relieve the patient's nausea, such as giving small sips of water, providing a cool and quiet environment, or using aromatherapy.

Choice B reason: Giving the patient small sips of tepid water is the best intervention for the nurse to facilitate. Water can help hydrate the patient and dilute any stomach acid that may cause irritation. Tepid water is water that is slightly warm, which can be more soothing than cold or hot water. Small sips can prevent the patient from swallowing too much air, which can worsen nausea and vomiting.

Choice C reason: Helping the patient lay supine is not a good intervention for the nurse to facilitate. Supine means lying flat on the back, which can increase the risk of aspiration, or inhaling food or fluids into the lungs. Aspiration can cause pneumonia, a serious lung infection. The nurse should help the patient lay on their side, with their head elevated, to prevent aspiration and reduce pressure on the stomach.

Choice D reason: Showing the patient how to use the patient-controlled analgesia is not a relevant intervention for the nurse to facilitate. Patient-controlled analgesia is a system that allows the patient to self-administer pain medication through an IV pump. It has nothing to do with nausea and vomiting, and may even cause them as side effects. The nurse should monitor the patient's pain level and adjust the analgesia settings as needed, but not as a way to treat nausea.
