Susan Marsh is a 65-year-old woman who has been diagnosed with arthritis and takes over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs). Susan comes to the clinic for a physical examination and tells the health care professional that she takes other medications ordered by other physicians but did not bring them with her today. Because nonsteroidal anti-inflammatory drugs (NSAIDs) can cause health problems in older adults, it is most important for the health care professional to assess Susan for:

a) Signs of hair thinning
b) Signs of tinnitus
c) Signs of constipation or diarrhea
d) Evidence of a "silent" gastrointestinal bleed
