The nurse explains that is regard to regulation by the Dietary Supplement Health and Education Act, dietary supplements:
do not have to demonstrate effectiveness
are determined to be safe before being placed on the market
are checked for label accuracy
are tested prior to marketing
The Correct Answer is A
- Do not have to demonstrate effectiveness:
This statement is generally true under DSHEA regulations. Unlike pharmaceutical drugs, dietary supplements are not required to undergo rigorous testing to demonstrate their effectiveness in treating, preventing, or curing specific health conditions before they are marketed. However, manufacturers are prohibited from making unsubstantiated claims about the effectiveness of their products.
B. Are determined to be safe before being placed on the market:
Under DSHEA regulations, dietary supplement manufacturers are responsible for ensuring the safety of their products before they are marketed. However, unlike pharmaceutical drugs, dietary supplements do not undergo premarket approval by the Food and Drug Administration (FDA) to verify their safety and efficacy. Instead, manufacturers are required to notify the FDA of their intent to market a new dietary ingredient (NDI) and provide evidence of the ingredient’s safety.
C. Are checked for label accuracy:
The FDA regulates dietary supplements to ensure that their labels are accurate and truthful. However, the extent of label accuracy checking varies, and the FDA does not routinely test every dietary supplement product on the market. Instead, the FDA relies on postmarket surveillance, consumer complaints, and other mechanisms to identify and address inaccuracies or violations of labeling regulations.
D. Are tested prior to marketing:
Unlike pharmaceutical drugs, dietary supplements are not required to undergo premarket testing to demonstrate their safety or efficacy before they are marketed. While manufacturers are responsible for ensuring the safety of their products, there is no formal premarket testing requirement under DSHEA regulations.

Correct Answer is D
Explanation
A. Not affected:
This choice suggests that taking ciprofloxacin with antacids does not alter its absorption. However, this is not correct. When ciprofloxacin is taken with antacids containing certain ions (such as aluminum, magnesium, or calcium), the absorption of ciprofloxacin can indeed be affected due to the formation of insoluble complexes, leading to decreased absorption.
B. Delayed:
This choice implies that taking ciprofloxacin with antacids delays its absorption. While it's true that the interaction between ciprofloxacin and certain antacids can alter absorption, the main effect is not typically a delay in absorption but rather a decrease due to the formation of insoluble complexes. Therefore, while "delayed" may somewhat describe the effect, it doesn't fully capture the nature of the interaction.
C. Increased:
This choice suggests that taking ciprofloxacin with antacids increases its absorption. However, this is not accurate. Antacids containing aluminum, magnesium, or calcium can interfere with the absorption of ciprofloxacin by forming insoluble complexes with the drug, leading to decreased absorption rather than an increase.
D. Decreased:
This choice correctly identifies the effect of taking ciprofloxacin with antacids. When ciprofloxacin is taken concurrently with antacids containing aluminum, magnesium, or calcium, the absorption of ciprofloxacin is decreased. The ions in the antacids bind with ciprofloxacin in the gastrointestinal tract, forming insoluble complexes that are poorly absorbed, thereby reducing the effectiveness of the antibiotic.
Correct Answer is A
Explanation
A. The patient stops taking the drug when he or she begins to feel better:
This choice refers to the common habit where patients discontinue their prescribed medication once they start to feel improvement in their symptoms, even if they haven't completed the full course of treatment. This premature cessation of medication can leave some microbes alive and potentially resistant to the antibiotic, allowing them to regrow and cause a recurrence of the infection.
B. The patient switches to multiple drug therapy from single drug therapy:
This choice describes a scenario where a patient switches from a single drug therapy to multiple drug therapy. While this may be a valid treatment approach in some cases, it is not directly related to the re-population and re-establishment of microbes causing an infection.
C. The patient uses OTC drugs prophylactically:
This choice involves patients using over-the-counter (OTC) drugs preventively without consulting a healthcare professional. While OTC drugs may have their own set of issues, such as contributing to antibiotic resistance, this behavior isn't specifically linked to the re-population and re-establishment of microbes causing an infection.
D. The patient increases the drug dosage when he or she perceives that the therapeutic effect of the drug is slowing down:
This choice describes a scenario where a patient independently increases the dosage of their medication without consulting a healthcare provider. While inappropriate dosage adjustments can lead to adverse effects, it doesn't directly address the re-population and re-establishment of microbes causing an infection.
