What desired outcomes should the nurse associate with this drug order? Response Feedback: Lactulose is used to reduce serum ammonia levels by pulling water into the colon. In this case, frequent, loose bowel movements are an expected outcome. A patient with hepatic coma or hepatic encephalopathy would not normally be expected to express an understanding of his or her drug regimen. The goal of treatment is not the relief of constipation. Bowel movements would not be formed. Question 34 1 out of 1 points A patient who is postoperative day one following a metatarsal amputation is experiencing nausea and vomiting. Consequently, the nurse has administered an intravenous dose of metoclopramide. This drug will relieve the patient's nausea by Response Feedback: Metoclopramide's mechanism of action is unclear. However, it appears to sensitize tissues to the effect of acetylcholine. It has the cholinergic-like effect on the upper GI tract of stimulating motility but does not stimulate gastric, pancreatic, or gallbladder secretions. The drug does not affect gastric pH, inhibit proton pumps, or eradicate H. Pylori. Question 35 1 out of 1 points A patient comes to the clinic asking for help to quit drinking alcohol. She has a 21-year history of heavy drinking and is worried about developing cirrhosis of the liver. The patient agrees to take disulfiram
(Antabuse). The nurse will teach the patient that the combination of alcohol and Antabuse will cause which of the following? Response Feedback: The effectiveness of Antabuse relies on a drug interaction between ethanol and disulfiram to produce unpleasant and undesirable symptoms as a deterrent to alcohol ingestion. Symptoms include facial flushing, throbbing headache, hyperventilation, tachycardia, palpitations, nausea and copious vomiting, hypotension, shortness of breath, vertigo, syncope, confusion, and profuse diaphoresis.
