Which of the following is a non-pharmacologic self-care example?

• A. Acetaminophen
• B. Ibuprofen
• C. Vitamin C
• D. Sleep hygiene

Answer: (D)

Non-pharmacologic self-care means actions you take that don’t involve medicines or supplements. Sleep hygiene fits this because it’s about daily habits and the environment to improve rest, without taking anything. Think of routines like going to bed at the same time, keeping the sleeping area quiet and dark, avoiding caffeine late in the day, limiting screens before bed, and using the bed only for sleep. These are behavior- and environment-based steps that promote health without drugs.

The other options involve substances you ingest to affect how you feel or function: acetaminophen and ibuprofen are pain-relief medications, and vitamin C is a dietary supplement. While helpful in different ways, they’re not non-pharmacologic self-care because they rely on taking a product rather than changing behavior or the surrounding environment.
