Final answer:
Factors increasing the risk for gastrointestinal bleeding, thus potentially leading to a positive Hemoccult test, are anticoagulants, long-term use of steroids, long-term use of NSAIDs, and acetylsalicylic acid (aspirin). A recent blood transfusion and antidiabetic agents are not typically associated with an increased risk of gastrointestinal bleeding.
Step-by-step explanation:
The factors that may increase a patient's risk for gastrointestinal bleeding and thus a positive Hemoccult test include the use of certain medications and health conditions. The following are factors that would increase this risk:
- Anticoagulants such as Lovenox, Heparin, and Coumadin, which work by preventing clot formation and thus can promote bleeding.
- Long-term use of steroids, which can cause thinning of the gastrointestinal lining, leading to an increased risk of ulcers and bleeding.
- Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), like ibuprofen, which can cause irritation, ulceration, and bleeding of the gastrointestinal tract.
- Acetylsalicylic acid (aspirin), which also has blood-thinning effects and can cause gastrointestinal bleeding.
Other listed options such as a recent blood transfusion or antidiabetic agents (oral hypoglycemics) do not typically increase the risk of gastrointestinal bleeding directly, so they would not normally result in a positive Hemoccult test.
