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: Oily stools are common, especially when excessive fat is consumed, because orlistat blocks the absorption of fat in the intestines. The undigested fat is then eliminated in the stool, making it oily, greasy, or foul-smelling.

Choice B reason: Many patients note having an increase of gas and flatus, because orlistat can also interfere with the digestion of carbohydrates and proteins, causing fermentation and gas production in the colon.

Choice C reason: Constipation is not a common side effect with this medication. In fact, orlistat may cause the opposite effect of diarrhea, as the unabsorbed fat can irritate the bowel and increase the motility.

Choice D reason: Some patients report the development of fecal incontinence, because orlistat can cause unpredictable bowel movements and difficulty in controlling the passage of stool, especially if the patient consumes a high-fat diet.

Choice E reason: This medication does have side effects, even though it can be bought over the counter. Orlistat is a prescription-strength drug that can cause serious adverse reactions, such as liver damage, kidney stones, gallbladder problems, and vitamin deficiencies. The over-the-counter version is a lower dose than the prescription one, but it still requires medical supervision and lifestyle changes.

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.
