Question 301 out of 1 pointsA patient with a long history of alcohol abuse has been admitted to an acute medical unit with signs and symptoms of hepatic encephalopathy.

His current medication orders include QID doses of oral lactulose. 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 311 out of 1 pointsIt is determined that a patient, who is in a hepatic coma, needs a laxative.Lactulose is prescribed. Which of the following should the nurse monitor toassess the efficacy of the lactulose therapy?Response Feedback:Similar to the saline laxative magnesium hydroxide, lactulose pulls water into the colon. Unlike magnesium hydroxide, lactulose is a synthetic disaccharide of lactose. In the colon, bacteria metabolize lactulose into acids and carbon dioxide, increasing the oncotic pressure in the colon and drawing water into the stool. The acids formed also draw ammonia into the stool. Therefore, lactulose is used not only to treat constipation but also to decrease blood ammonia levels in patients in hepatic coma and those with hepatic encephalopathy. The otherfactors, although significant, would not indicate the efficacy of the lactulose therapy as accurately as blood ammonia levels.Question 321 out of 1 pointsA teenage boy has undergone a diagnostic workup following several months of persistent, bloody diarrhea that appears to lack an infectious etiology. The boy has also experienced intermittent abdominal pain and has lost almost 15 pounds this year. Which of the following medications is most likely to treat this boy's diagnosis?Response Feedback:This patient's history and presentation are strongly suggestive of ulcerative colitis, a disease for which mesalamine is an approved treatment. Lubiprostone is used for the treatment of constipation and docusate is a stool softener. Bismuth subsalicylate is an antidiarrheal but is not effective in the management of ulcerative colitis.Question 331 out of 1 pointsA nurse is assessing a female patient who is taking diphenoxylate HCl withatropine sulfate. Which of the following would lead the nurse to suspect that she is experiencing an allergic reaction?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
