A nurse is caring for a client who has a prescription for a stool test for occult. The nurse understands the purpose of the test is to check the stool for which of the following substances?
Bacteria
Parasites
Steatorrhea
Blood
The Correct Answer is D
Choice A rationale: The stool test for occult blood is not primarily designed to detect bacteria.
Choice B rationale: Parasites are not typically detected through a stool test for occult blood.
Choice C rationale: Steatorrhea refers to the presence of excess fat in the stool and is not the primary focus of a stool test for occult blood.
Choice D rationale: The purpose of the stool test for occult blood is to check for the presence of blood in the stool, which may not be visible to the naked eye. This can be an indicator of gastrointestinal bleeding.
