NSG4067 CH1 (8) Questions {Answered Correctly! }

Chapter 8 Medications and Other Bioactive Substances 1. A nurse assesses the eating habits of a 75-year-old client who takes iron supplements for iron deficiency anemia. Which of the following statements by the client indicates a need for further teaching? A) "I drink orange juice with my iron." B) "I prefer coffee to take my pills." C) "I take all my pills with a glass of warm water." D) "I take my iron in between my meals." Ans: B Feedback: Foods that change the pH of the gastrointestinal (GI) system interfere with the absorption of iron. It is best taken on an empty stomach, but if it causes GI upset, then it can be taken with orange juice, which helps absorption. Caffeine and some foods interfere with iron absorption. The temperature of the water should not impact the medication absorption. 2. A healthy 70-year-old has been using diphenhydramine (Benadryl) for allergic rhinitis. One week later, the client begins to exhibit signs of confusion and disorientation. The spouse calls the primary care facility to speak with the nurse. Which event should the nurse suspect first? A) The older adult has hyponatremia, leading to delirium. B) The older adult is having transient ischemic attacks. C) The older adult has an overwhelming infection. D) The older adult is experiencing an adverse drug effect. Ans: D Feedback: The older adult has been taking diphenhydramine, which can have an anticholinergic effect. Anticholinergic drugs can lead to medication-induced cognitive impairment. There is no reason to think that the client has hyponatremia. Rhinitis does not generally cause delirium in older adults. The client is more likely to be having adverse reaction than transient ischemic attacks. 3. An older adult, aged 72, with type 2 diabetes and coronary artery disease is admitted to a longterm care facility. The client takes glipizide (Glucotrol) and isosorbide mononitrate (Imdur). The medical history states that the client drank 4 ounces of whiskey per day for many years. Which of the following actions should be a priority for the admitting nurse? A) Assess and observe for depression. B) Assess for hypoglycemia and hypotension.
