The client asks the nurse how to compare the strengths of different brands of an herbal supplement. Which response by the nurse is the most appropriate?
1. "Look for a label with an NSF or United States Pharmacopoeia (USP) certification, which indicates that the strength of the herb has been quantified."
2. "There is no way to compare the strengths of any herbal products in the United States."
3. "If the supplement is standardized, you can compare the amount of active ingredient in different products."
4. "There is no need to check strengths. All products in the United States are standardized."
Correct Answer: 3
Rationale 1: The USP certification addresses the purity, not the strength, of a product. Standardization identifies the strength of the herb or supplement.
Rationale 2: Standardization allows for strength comparisons among some available products.
Rationale 3: The active ingredient in some herbal supplements is standardized. Standardization uses a marker substance, such as a percentage of an herb's active ingredient, to quantify a product's potency. This can allow for strength comparisons among available products.
Rationale 4: Not all herbal preparations or supplements are standardized.
