How does drug therapy of tuberculosis differ from that of most other infections?

Choice A rationale
Taking less than the recommended dose initially may not provide the desired therapeutic effect and could lead to misunderstanding about the effectiveness of the herbal product.
Choice B rationale
While it’s true that some herbal products should not be taken with prescription medications due to potential interactions, this is not the best way to identify allergic or other adverse reactions.
Choice C rationale

While checking with a reputable pharmacist is always a good idea when starting any new medication or supplement, it is not the best way to identify allergic or other adverse reactions.
Choice D rationale
Using only one herbal preparation at a time is the best way to identify allergic or other adverse reactions. If multiple herbal products are started at the same time and an adverse reaction occurs, it would be difficult to determine which product caused the reaction.

Choice A rationale
While it’s true that poor circulation can affect drug distribution in older adults, this is not the primary reason antianxiety medications are used cautiously in this population.
Choice B rationale
While the liver’s ability to metabolize drugs can decrease with age, leading to increased drug levels in the body, this is not the primary reason antianxiety medications are used cautiously in older adults.
Choice C rationale
Decreased acid production can affect the absorption of certain drugs, but this is not the primary reason antianxiety medications are used cautiously in older adults.

Choice D rationale
Reduced elimination of drugs is a key concern in older adults. This can lead to a buildup of drugs in the body, increasing the risk of side effects. This is particularly true for antianxiety medications, which can cause side effects such as dizziness, confusion, and falls.
