Chapter 7 : Over-the-Counter Drugs and Herbal and Dietary Supplements Questions
Question 1 of 5
The nurse is giving a lecture about current U.S. laws and regulations of herbal products. According to the United States Dietary Supplement and Health Education Act of 1994, which statement is true?
Correct Answer: A
Rationale: Current U.S. laws, under the Dietary Supplement Health and Education Act of 1994, classify herbal products as dietary supplements, not subject to the same rigorous efficacy and safety standards as drugs. Producers are not required to prove therapeutic efficacy, and herbal remedies are not specifically protected by patent laws.
Question 2 of 5
The patient wants to take the herbal product kava to help him rest at night. The nurse would be concerned about potential interactions if he is taking a medication from which class of drugs?
Correct Answer: C
Rationale: Kava may cause increased central nervous system depression when combined with sedatives, leading to potential interactions. No significant interactions are noted with digitalis, anticoagulants, or immunosuppressants.
Question 3 of 5
The patient has been taking an over-the-counter (OTC) acid-reducing drug because he has had 'stomach problems' for several months. He tells the nurse that the medicine helps as long as he takes it, but once he stops it, the symptoms return. Which statement by the nurse is the best advice for this patient?
Correct Answer: D
Rationale: The use of OTC drugs may relieve symptoms but does not address underlying causes of chronic conditions. Consulting a healthcare provider is necessary to investigate the cause of persistent symptoms, rather than relying solely on OTC medication or dietary changes.
Question 4 of 5
During an assessment, the patient tells the nurse that he takes a garlic supplement for its cardiovascular benefits. Which drug or drug class, if taken, would have a potential interaction with the garlic?
Correct Answer: B
Rationale: Garlic may interfere with hypoglycemic drugs like insulin, potentially affecting blood sugar control. No significant interactions are noted with acetaminophen, antilipemic drugs, or sedatives.
Question 5 of 5
A patient calls the clinic to ask about taking cranberry dietary supplement capsules because a friend recommended them. The nurse will discuss which possible concern when a patient is taking cranberry supplements?
Correct Answer: C
Rationale: Cranberry can decrease the elimination of drugs that are renally excreted, potentially increasing their effects or toxicity. It does not significantly affect bleeding risk, psychotherapeutic drugs, or caffeine effects.
