Question 1 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 2 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.
Question 3 of 5
A patient wants to take the herb gingko to help his memory. The nurse reviews his current medication list and would be concerned about potential interactions if he is taking a medication from which class of drugs?
Correct Answer: B
Rationale: Gingko increases the risk of bleeding when taken with antiplatelet drugs (e.g., aspirin, clopidogrel) or anticoagulants. No significant interactions are noted with digitalis, sedatives, or immunosuppressants.
Question 4 of 5
The nurse is conducting a class for senior citizens about the use of over-the-counter (OTC) drugs. Which statements are true regarding the use of OTC drugs? (Select all that apply.)
Correct Answer: A,C,E
Rationale: OTC drugs may delay treatment of serious ailments, relieve symptoms without addressing the cause, and patients may misunderstand labels, leading to improper use. Drug interactions with OTC medications are not rare, and OTC drugs are typically intended for short-term, not long-term, treatment.
Question 5 of 5
The nurse is reviewing the criteria for over-the-counter drugs. Which criteria for over-the-counter status in the United States are accurate? (Select all that apply.)
Correct Answer: A,C,D
Rationale: Criteria for OTC status in the U.S. include the drug being easy to use, having a low potential for abuse, and allowing consumers to monitor effectiveness. The drug should have a high therapeutic index (not low) and limited, not zero, interactions with other drugs.
