Chapter 50 : Acid-Controlling Drugs Questions
Question 1 of 5
A patient will be taking a 2-week course of combination therapy with omeprazole and another drug for a peptic ulcer caused by Helicobacter pylori. The nurse expects a drug from which class to be ordered with the omeprazole?
Correct Answer: A
Rationale: The antibiotic clarithromycin is active against H. pylori and is used in combination with omeprazole to eradicate the bacteria. First-line therapy against H. pylori includes a 10- to 14-day course of a proton pump inhibitor such as omeprazole, plus the antibiotics clarithromycin and either amoxicillin or metronidazole, or a combination of a proton pump inhibitor, bismuth subsalicylate, and the antibiotics tetracycline and metronidazole.
Question 2 of 5
A patient is asking advice about which over-the-counter antacid is considered the most safe to use for heartburn. The nurse explains that the reason that calcium antacids are not used as frequently as other antacids is for which of these reasons?
Correct Answer: A
Rationale: Calcium antacids are not used as frequently as other antacids because their use may lead to the development of kidney stones; they also cause increased gastric acid production.
Question 3 of 5
At 0900, the nurse is about to give morning medications, and the patient has asked for a dose of antacid for severe heartburn. Which schedule for the antacid and medications is correct?
Correct Answer: C
Rationale: Medications are not to be taken, unless prescribed, within 1 to 2 hours of taking an antacid because of the impact on the absorption of many medications in the stomach.
Question 4 of 5
During an admission assessment, the patient tells the nurse that he has been self-treating his heartburn for 1 year with over-the-counter Prilosec OTC (omeprazole, a proton pump inhibitor). The nurse is aware that this self-treatment may have which result?
Correct Answer: D
Rationale: Long-term self-medication with antacids may mask symptoms of serious underlying diseases, such as bleeding ulcer or malignancy. Patients with ongoing symptoms need to undergo regular medical evaluations, because additional medications or other interventions may be needed.
Question 5 of 5
An older adult patient had gastric surgery due to a gastrointestinal bleed 3 days ago, and he has been stable since the surgery. This evening, his daughter tells the nurse, 'He seems to be more confused this afternoon. He's never been like this.' What could be the problem? The nurse reviews the patient's medication record and suspects that which drug could be the cause of the patient's confusion?
Correct Answer: A
Rationale: Sometimes H2 receptor antagonists such as cimetidine may cause adverse effects related to the central nervous system in the older adult, including confusion and disorientation.
