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

Answer and Explanation

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 D

Explanation

Choice A Reason:

Hyperkalemia is incorrect. Vomiting and diarrhea typically lead to a loss of potassium rather than an increase. These conditions often result in depletion of electrolytes, including potassium, due to the loss of fluids.

Choice B Reason:

Hypocalcemia is correct. While prolonged or severe diarrhea could potentially lead to some electrolyte imbalances, hypocalcemia is not typically a primary finding associated with vomiting and diarrhea. Calcium levels may not be significantly affected by these symptoms compared to sodium and potassium.

Choice C Reason:

Hypermagnesemia is incorrect. Similar to calcium, magnesium levels are not usually significantly impacted by vomiting and diarrhea alone. Hypermagnesemia is more commonly associated with excessive intake of magnesium-containing medications or renal dysfunction rather than acute gastrointestinal symptoms.

In a client experiencing vomiting and diarrhea, the loss of fluids and electrolytes due to these symptoms commonly leads to:

Choice D Reason:

Hyponatremia is correct. Vomiting and diarrhea can cause a loss of sodium and water, leading to decreased sodium levels in the blood, which manifests as hyponatremia. This electrolyte imbalance is a typical finding in individuals experiencing gastrointestinal issues with fluid loss.

A. Apply intermittent suction for up to 30 seconds. B. Preoxygenate the client prior to suctioning. C. Instruct the client to swallow during catheter insertion. D. Apply suction while inserting the catheter.

Correct Answer is B

Explanation

Choice A Reason:

Applying intermittent suction for up to 30 seconds is incorrect. While suctioning is necessary for tracheostomy care, the duration and frequency of suctioning should be based on the client's need and should typically last no more than 10-15 seconds to prevent hypoxemia and tissue damage.

Choice B Reason:

Preoxygenate the client prior to suctioning is correct. Preoxygenation helps ensure that the client has adequate oxygen levels before the suctioning procedure, reducing the risk of hypoxemia or decreased oxygen levels during and after suctioning

Choice C Reason:

Instruct the client to swallow during catheter insertion is incorrect. Instructing the client to swallow during catheter insertion is not a standard procedure for tracheostomy care. Swallowing doesn't have a direct association with the suctioning process.

Choice D Reason:

Apply suction while inserting the catheter is incorrect. Applying suction during catheter insertion can cause tissue damage and should be avoided. Suction should only be applied when withdrawing the catheter to remove secretions from the tracheostomy tube.
