NURS-6521N Advanced Pharmacology Summer Week 7 - Quiz Completed Attempt Score 35 out of 35 points  Question 1 1 out of 1 points A 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? Mesalamine 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 2 1 out of 1 points Mr. Tan is a 69-year-old man who prides himself in maintaining an active lifestyle and a healthy diet that includes adequate fluid intake. However, Mr. Tan states that he has experienced occasional constipation in recent months. What remedy should be the nurse's first suggestion? A bulk-forming (fiber) laxative Response Feedback: Bulk-forming (fiber) laxatives are considered the safest and most physiologic of the laxatives. As such, they are normally preferable to stimulant and hyperosmotic laxatives for occasional relief of constipation. Bismuth subsalicylate does not relieve constipation.  Question 3 1 out of 1 points A 57-year-old man is to begin 5-FU therapy for colon cancer. It will be most important for the nurse to monitor which of the following during the first 72 hours of the initial treatment cycle? Cardiac events Response Feedback: The nurse should closely monitor the patient for cardiac events because cardiotoxicity is an important toxicity associated with 5-FU. Cardiac events typically occur during the first 72 hours of the initial treatment cycle. The WBC nadir occurs within 10 to 14 days after the drug is administered, and myelosuppression, nausea, and vomiting are dose-limited adverse effects of 5-FU therapy.  Question 4 1 out of 1 points Mesalamine (Asacol) is prescribed for a 22-year-old woman with Crohn disease. The nurse will discuss with the patient the possibility for which of the following adverse effects related to the new drug therapy? Hair loss Response Feedback: The nurse will explain that one possible adverse effect of mesalamine (Asacol) therapy is hair loss. The nurse will emphasize that the hair loss is generally mild and transient. Metallic taste, fatigue, and increased appetite are not adverse effects of mesalamine.  Question 5 1 out of 1 points A nurse is aware that diphenoxylate HCl with atropine sulfate is an effective adjunct in the treatment of diarrhea. For which of the following patients could the administration of this drug be potentially harmful? An 80-year-old man who has diarrhea secondary to Clostridium difficile infection Response Feedback: Use of diphenoxylate HCl is contraindicated for diarrhea caused by GI organisms that penetrate the gastric mucosa (such as C. difficile) because the drug slows peristalsis and may aggravate and prolong the diarrhea. Diarrhea associated with stress, influenza, and tube feeding can be safely treated with the drug in most cases.  Question 6 1 out of 1 points A 48-year-old woman who works as an office manager is prescribed metoclopramide (Reglan) for diabetic gastroparesis. The nurse will be sure to assess the patient for depression. Response Feedback: Depression, from mild to severe, including suicidal ideation, has occurred in patients with and without a history of depression who take metoclopramide. Use caution in administering metoclopramide to patients with a history of depression. The nurse should assess the patient for signs of depression and monitor behavior as long as the patient is on the therapy. If the patient has been depressed or is depressed, metoclopramide therapy should be given only if the benefits of the drug outweigh the potential risks from depression. Tachycardia, hypotension, and anemia are not associated with metoclopramide.  Question 7 1 out of 1 points Following an endoscopy, a 66-year-old man has been diagnosed with a duodenal ulcer resulting from Helicobacter pylori infection. Which of the following medications will likely be used in an attempt to eradicate the patient's H. pylori infection? (Select all that apply.) Antibiotics A PPI Response Feedback: Classic quadruple therapy for H. pylori eradication (bismuth, a PPI, 1,500 mg of metronidazole, and 1,500 mg of tetracycline) is highly effective and is frequently the regimen of choice. A newer sequential therapy (PPI plus amoxicillin followed by a PPI plus clarithromycin plus metronidazole) has been proposed and is expected to replace legacy therapy. Both regimens include PPIs and antibiotics and exclude aluminum hydroxide, ondansetron, and cisapride.  Question 8 1 out of 1 points A nurse is assessing a female patient who is taking diphenoxylate HCl with atropine sulfate. Which of the following would lead the nurse to suspect that she is experiencing an allergic reaction? Urticaria Response Feedback: Although numbness of extremities, headache and lethargy, and toxic megacolon are possible adverse effect of diphenoxylate HCl with atropine sulfate therapy, urticaria would indicate an allergic reaction to the drug.  Question 9 1 out of 1 points A clinic nurse is planning care for a 68-year-old man who has been on omeprazole (Prilosec) therapy for heartburn for some time. Regarding the patient's safety, which of the following would be a priority nursing action? Coordinate bone density testing for the patient. [Show More]
