Final answer:
The client should avoid consuming red meat, raw fruits and vegetables, and vitamin C supplements for the 3 days before the test to ensure accurate results.
Step-by-step explanation:
The client can determine if teaching about dietary restrictions for a fecal occult blood test has been successful if they make the statement, "I will avoid consuming red meat, raw fruits and vegetables, and vitamin C supplements for the 3 days before the test." These dietary restrictions are necessary to prevent false-positive results in the test. Consuming red meat, raw fruits and vegetables, and vitamin C can interfere with the accuracy of the test by causing false-positive results or masking the presence of blood in the stool.
