A nurse is caring for a client who follows a lacto-vegetarian diet. Which of the following food choices should the nurse recommend?

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.

Choice A Reason:

Obtaining urine from the drainage bag if a urinary specimen is required is incorrect.

While obtaining urine from the drainage bag might seem practical for specimen collection, it's not the recommended method due to potential contamination of the specimen. A sterile sampling port or aspirating urine from the catheter tubing is a more appropriate technique.

Choice B Reason:

Using a catheter securing device to hold the catheter in place is correct. Securing the catheter with a proper securing device helps prevent unnecessary movement or tension on the catheter, reducing the risk of trauma to the urinary tract and ensuring stability for the catheter.

Choice C Reason:

Positioning the drainage bag higher than the client's bladder is incorrect. Positioning the drainage bag higher than the bladder can lead to backflow or reflux of urine, increasing the risk of urinary tract infections. The drainage bag should be placed below the level of the bladder to facilitate proper drainage.

Choice D Reason:

Changing the catheter bag every 3 days and as needed is incorrect. Routine changing of catheter bags every three days without clinical indication for changing can increase the risk of introducing infection. Catheter bags are changed based on clinical indications or when they are soiled or damaged, not on a fixed time schedule.
