A nurse is caring for a client who is angry and states, "The doctor gave me the wrong information. I was lied to!" Which of the following responses by the nurse is appropriate?

Choice A Reason:

Discontinuing supplements containing vitamin C 24 hr before the test is appropriate. This is not necessary for fecal occult blood testing. However, vitamin C supplements should be avoided before certain stool tests that use a chemical reaction involving guaiac.

Choice B Reason:

Placing a thick layer of stool on the specimen card is inappropriate. The client should apply a small amount of stool to the designated area on the specimen card. A thick layer is not required, and excess stool may interfere with the test.

Choice C Reason:

Urinating prior to collecting the stool specimen is appropriate. This instruction is important because it helps prevent contamination of the stool specimen with urine, which could potentially interfere with the accuracy of the test results.

Choice D Reason:

Refraining from consuming pork 7 days before the test is inappropriate. There is no need for the client to avoid consuming pork specifically for fecal occult blood testing. The instructions usually focus on dietary restrictions that could affect the presence of blood in the stool, such as avoiding red meat or certain medications.

Choice A Reason:

Adding 0.5 mL of diluent to the medication is inappropriate action. Ampules typically contain a single-dose of medication in a liquid form, and dilution is not necessary unless specified by the medication order or manufacturer.

Choice B Reason:

This is not necessary as the tip of the ampule is already sterile before opening. Cleansing after opening does not provide additional benefit and can introduce contaminants.

Choice C Reason:

Using a filter needle to aspirate the medication is inappropriate. Filter needles are not routinely used for administering medication from ample.

Choice D Reason:

This is not appropriate for ampules. Unlike vials, ampules do not require air to be injected. Air injection is necessary only for vials to create pressure, but ampules are opened and medication is drawn directly without the need for air.
