Pharmacy Technician Certification Board Practice Exam Practice Question

Correct Answer: A

Rationale: Adsorption can lead to a medication losing potency as it binds to surfaces, reducing the amount available for therapeutic effect. This process can occur with various materials, including containers and surfaces, leading to decreased efficacy.

Option B, contamination, typically involves microbial or chemical impurities, which is not directly related to adsorption.

Option C, requiring refrigeration, is based on stability and degradation factors rather than adsorption.

Option D, triggering anaphylaxis, is an immune response to allergens and not a direct consequence of adsorption. Thus, the most relevant outcome of adsorption is the loss of potency.
