A nurse is teaching a newly licensed nurse about obtaining a fecal occult blood test from a client.
Which of the following information should the nurse include?
Collect two stool specimens from the same area of the stool.
Use toilet paper to transfer the stool specimen.
Apply four drops of developing solution to each stool specimen.
Wait 30 seconds after applying the developing solution to obtain the results.
The Correct Answer is D
Choice A rationale
Collecting two stool specimens from the same area of the stool is incorrect because specimens should be taken from different areas to ensure a representative sample of the stool for testing.
Choice B rationale
Using toilet paper to transfer the stool specimen is not recommended as it can contaminate the sample and interfere with test results.
Choice C rationale
Applying four drops of developing solution to each stool specimen is incorrect. The usual procedure involves applying a specific number of drops as indicated by the test instructions, which may vary.
Choice D rationale
Waiting 30 seconds after applying the developing solution is correct. This waiting period allows the test to react and provide accurate results for the presence of occult blood.

Correct Answer is C
Explanation
Choice A rationale
Including toilet paper with the collected urine can contaminate the sample and affect the accuracy of the test results.
Choice B rationale
The first void at the start of the collection period should be discarded to ensure that only urine produced during the 24-hour period is collected.
Choice C rationale
Refrigerating the urine during the collection period helps preserve the sample and prevent bacterial growth, which could alter the test results.
Choice D rationale
The last void at the end of the collection period should be included to ensure that the full 24-hour period is accounted for in the collection.
Correct Answer is C
Explanation
Choice A rationale
The end of the stoma is typically not painful after the procedure. Pain at the stoma site could indicate complications such as infection or ischemia.
Choice B rationale
A healthy stoma should be pink or red in color. A purple color could indicate compromised blood flow or other complications that require medical attention.
Choice C rationale
The stoma is typically placed in the right lower abdomen to allow for easier management and care, as it is usually associated with the terminal ileum.
Choice D rationale
After an ileostomy, the stool is usually liquid to semi-formed, not solid, because the colon, which absorbs water to solidify stool, is bypassed.
