A client admitted with acute diverticulitis has experienced a sudden increase in temperature and reports a sudden onset of extreme abdominal tenderness. The nurse's rapid assessment reveals that the client's abdomen is uncharacteristically rigid on palpation. What is the nurse's best response?

Choice A reason: This is not a correct statement because these medications do not coat the ulcer. They are not antacids or mucosal protectants, which can form a protective layer over the ulcer and neutralize the stomach acid.

Choice B reason: This is not a correct statement because these medications do not stop the acid production. They only reduce it by inhibiting the proton pump, which is responsible for secreting acid into the stomach.

Choice C reason: This is not a correct statement because these medications should be taken as prescribed, not as needed. They are not analgesics or anti-inflammatory drugs, which can relieve the pain and inflammation of the ulcer.

Choice D reason: This is a correct statement because these medications have two effects: they kill the bacteria that cause the infection and inflammation of the ulcer, and they reduce the acid production that aggravates the ulcer. This can help heal the ulcer and prevent complications.

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.
