The Correct Answer is C

Choice B rationale
Anxiolytics are medications that inhibit anxiety. They are used to treat anxiety disorders and relieve short-term anxiety symptoms. While some anxiolytics do have sedative effects, they are not derived from barbituric acid.

Correct Answer is A
Explanation
Choice A rationale
Cephalosporins are a class of antibiotics that are chemically related to penicillin. They have a similar mechanism of action and a similar core chemical structure. Because of these similarities, there is a risk of cross-reactivity between penicillins and cephalosporins, meaning that a person who is allergic to penicillin may also have an allergic reaction to cephalosporins.
Choice B rationale
Sulfonamides are a different class of antibiotics and do not have a chemical structure similar to penicillin. While a person could be allergic to both penicillin and sulfonamides, this would be due to two separate allergies, not a cross-reactivity.
Choice C rationale
Macrolides are another class of antibiotics that are not chemically related to penicillin. There is no known cross-reactivity between penicillin and macrolides.
Choice D rationale
Aminoglycosides are a class of antibiotics that are not chemically related to penicillin. There is no known cross-reactivity between penicillin and aminoglycosides.
Correct Answer is D
Explanation
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.
