You are the student nurse teaching a patient about what foods to avoid prior to collection of a fecal occult blood test. The patient will need more education if the patient states:
I can eat 1-2 oranges
I will tell my wife that I cannot have grapefruit
I will not eat my raw vegetables for lunch
I will need to avoid lamb, beef, and pork
The Correct Answer is B
a) I can eat 1-2 oranges: Oranges are generally safe to eat prior to a fecal occult blood test. However, vitamin C-rich foods like citrus fruits should typically be avoided in large quantities before the test as they may interfere with the results. A small amount, such as 1-2 oranges, is acceptable.
b) I will tell my wife that I cannot have grapefruit: Grapefruit is rich in vitamin C, and high levels of vitamin C can interfere with the accuracy of the fecal occult blood test. This statement suggests a misunderstanding of which foods to avoid.
c) I will not eat my raw vegetables for lunch: Raw vegetables, particularly cruciferous ones like broccoli and cauliflower, are generally recommended to avoid prior to the test as they can cause false positives. The patient is correct in avoiding them.
d) I will need to avoid lamb, beef, and pork: Red meats like lamb, beef, and pork should be avoided before the test as they can cause false positives. The patient is correct in avoiding these meats.

Correct Answer is A
Explanation
a) Fecal Impaction: Seepage or leaking of liquid stool often occurs when a patient has a fecal impaction. The liquid stool may leak around the solid mass of stool that is impacted in the colon.
b) Urinary Incontinence: Urinary incontinence refers to the involuntary loss of urine, not stool.
c) Bowel and Bladder training program: While bowel and bladder training programs may be helpful for managing incontinence, they are not the immediate solution for fecal impaction.
Correct Answer is D
Explanation
a) Dark black visible blood: Dark, black blood is typically a sign of blood that has been digested, often due to gastrointestinal bleeding, but this is not the definition of occult blood.
b) Bright red visible blood: Bright red blood is usually a sign of recent bleeding, often from hemorrhoids or anal fissures. Occult blood refers to blood that is not visible.
c) Blood that contains mucus: Blood with mucus is not the definition of occult blood. Occult blood refers to blood that is hidden and cannot be seen without further testing.
d) Blood that cannot be seen: Occult blood refers to hidden blood that is not visible to the naked eye but can be detected through specific tests, such as a fecal occult blood test (FOBT).
