A nurse is reinforcing discharge teaching about fecal occult blood testing with include in the teaching?
Discontinue supplements containing vitamin C 24 hr. before the test
Refrain from consuming pork 7 days before the test.
Place a thick layer of stool on the specimen card.
Urinate prior to collecting the stool specimen
The Correct Answer is D
Choice A Reason:
Discontinuing supplements containing vitamin C 24 hr. before the test is incorrect. While high doses of vitamin C might interfere with the accuracy of some laboratory tests, it typically doesn't impact fecal occult blood testing. However, it's always best to follow specific instructions provided by the healthcare provider or laboratory.
Choice B Reason:
Refraining from consuming pork 7 days before the test. There isn't typically a requirement to avoid specific foods, such as pork, before a fecal occult blood test. The test is designed to detect blood in the stool, regardless of the diet. However, some dietary restrictions might be advised based on specific instructions or conditions, but these are not universally applicable.
Choice C Reason:
Placing a thick layer of stool on the specimen card is incorrect. When collecting a sample for a fecal occult blood test, it's important to follow the specific instructions provided by the healthcare provider or laboratory. Generally, a small portion of stool is applied to the designated area on the specimen card as instructed, rather than applying a thick layer. Applying too much stool can affect the accuracy of the test.
Choice D Reason:
Urinating prior to collecting the stool specimen is correct. This instruction ensures that the urine doesn't contaminate the stool sample, which could potentially affect the accuracy of the test results.

Correct Answer is A
Explanation
Choice A Reason:
A filter needle is used to prevent any glass particles from entering the syringe when drawing medication from an ampule, as ampules are made of glass that can sometimes break and leave shards.
Choice B Reason:
Adding 0.5 ml of diluent to the medication is incorrect. Adding diluent to medication from an ampule is not a standard practice. Ampules usually contain pre-measured doses of medication and are designed for direct withdrawal without dilution. Adding diluent could alter the concentration and effectiveness of the medication.
Choice C Reason:
The ampule should be cleansed before opening to remove any potential contaminants. Once the ampule is opened, the inside of the ampule and the medication should be considered sterile, so there is no need to cleanse the tip after opening.
Choice D Reason:
Injecting air into the ampule prior to drawing the medication into a syringe is incorrect. This action is not typically necessary when withdrawing medication from an ampule. Some medications may require air to equalize pressure, but it's crucial to follow specific guidelines for each medication. In most cases, creating positive pressure by injecting air into the ampule is not recommended, as it could affect the stability or integrity of the medication.
Correct Answer is B
Explanation
Choice A Reason:
"I'm sure it's nothing serious and their appetite will return soon." Is incorrect. This response dismisses the concern without addressing the underlying issue. It might overlook potential reasons for the lack of appetite and could lead to neglecting a serious problem.
Given the concern about the client not eating, the most appropriate response for the nurse to make would be:
Choice B Reason:
"Tell me more about what happens at mealtime." Is correct. This response encourages the child to share specific details about the mealtime routine, any challenges, or reasons behind the lack of eating. It allows the nurse to gather more information, identify potential issues, and offer appropriate guidance or interventions. Understanding the context surrounding the eating habits can help determine the best approach to address the situation effectively.
Choice C Reason:
"Why do you think they're not eating?" is incorrect. While it encourages discussion, this response puts the responsibility on the child to provide explanations that they might not fully understand or be equipped to articulate. It's essential for the nurse to gather information but in a more supportive and guiding manner.
Choice D Reason:
"They may need a feeding tube." Is incorrect. Jumping to a conclusion about a feeding tube without gathering more information or exploring other possibilities could alarm the child unnecessarily. This response could also create unnecessary worry for the child and the family without assessing the situation comprehensively.
