A nurse is providing discharge teaching for a patient who is going home with a guaiac test. Which statement by the patient indicates the need for further education?
a. "If I get a positive result, I have gastrointestinal bleeding."
b. "I should not eat red meat before my examination."
c. "I should schedule to perform the examination when I am not menstruating."
d. "I will need to perform this test three times if I have a positive result."
A
A positive result does not mean GI bleeding; it could be a false positive from consuming red meat, some raw vegetables, or NSAIDs. Proper patient education is important for viable results. The patient needs to avoid certain foods to rule out a false positive. If the test is positive, the patient will need to repeat the test at least three times. Menses and hemorrhoids can also lead to false positives.
