chelsea occasionally takes aspirin to relieve a headache. chelsea is
a) unlikely to feel an effect for as long as thirty minutes.
b) using a transdermal drug.
c) likely to develop cross - tolerance.
d) taking a psychoactive drug.

Explanation:

• Option A: Aspirin (acetyl - salicylic acid) is a non - steroidal anti - inflammatory drug (NSAID). When taken orally, it is absorbed relatively quickly. The onset of action for aspirin to relieve pain (like a headache) is usually within 15 - 30 minutes. So, it is unlikely that it would take as long as thirty minutes to feel an effect.
• Option B: Transdermal drugs are delivered through the skin. Aspirin is typically taken orally (swallowed as a pill), not via a transdermal route.
• Option C: Cross - tolerance occurs when tolerance to one drug leads to tolerance to another drug with a similar mechanism of action. Since Chelsea is only taking aspirin occasionally, there is no indication of repeated exposure to multiple drugs that would lead to cross - tolerance.
• Option D: Psychoactive drugs act on the central nervous system to alter mood, perception, or behavior. Aspirin primarily acts as an anti - inflammatory, analgesic (pain - reliever), and antipyretic (fever - reducer) through its action on cyclooxygenase (COX) enzymes, not on the central nervous system in the way that psychoactive drugs do.

Answer:

A. unlikely to feel an effect for as long as thirty minutes.
