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 D
Explanation
a) Have edema to the lower extremities: Edema can be caused by various factors such as heart failure, kidney disease, or poor circulation, but it is not directly related to a balance between energy intake and expenditure.
b) Increase: If energy intake equals energy expenditure, there is no surplus of energy to cause weight gain.
c) Decrease: If energy intake equals energy expenditure, there is no energy deficit to cause weight loss.
d) Stay the same: When a person's daily energy intake equals their total energy expenditure, their weight remains stable because the amount of energy taken in is exactly balanced with the amount of energy used.
