A nurse is checking for the proper placement of a feeding tube. Which of the following methods is the most reliable for verification of tube placement?
Verify the bilirubin level of the tube contents.
Auscultate for air insufflation.
Request a chest x-ray.
Check the pH level of gastric contents.
The Correct Answer is C
Choice A Reason:
Verifying the bilirubin level of the tube contents is incorrect. Measuring bilirubin levels in the tube contents is not a standard or reliable method for confirming tube placement. It's not an established or recommended technique for this purpose.
Choice B Reason:
Auscultating for air insufflation is incorrect. Auscultation for air insufflation involves injecting air into the tube and listening for bubbling sounds over the stomach area. While this method is commonly used, it can sometimes yield inconsistent or inconclusive results, especially in patients with certain conditions or situations where air movement might not be detectable.
Choice C Reason:
Request a chest x-ray is correct. Obtaining a chest x-ray is the most reliable method to confirm the placement of a feeding tube, especially when the tube is newly inserted or if there are any doubts about its location. A chest x-ray can accurately visualize the position of the tube within the gastrointestinal tract, ensuring it is in the intended location before any feedings or medications are administered.
Choice D Reason:
Checking the pH level of gastric contents is incorrect. Measuring the pH level of aspirated gastric contents can provide information about the acidity of the fluid, indicating gastric placement (pH below 5) in most cases. However, the pH can be influenced by various factors like medications, enteral feeding solutions, or certain medical conditions, making it less reliable than a chest x-ray for definitive confirmation of tube placement.

Correct Answer is D
Explanation
Choice A Reason:
Turn the client every 4 hr. is incorrect. While repositioning is crucial for preventing pressure ulcers in immobile patients, turning the client every 4 hours might not directly address the issue of fecal incontinence or skin protection in the perineal area.
Choice B Reason:
Cleanse the perineal area with povidone-iodine solution is incorrect. Povidone-iodine solution might be too harsh for routine perineal care and can potentially irritate the skin. A gentler cleansing solution is typically recommended to avoid further skin irritation.
Choice C Reason:
Apply cornstarch powder to the perineal area is incorrect. Cornstarch powder might exacerbate moisture-related skin issues in the perineal area by creating a damp environment, potentially leading to skin maceration and worsening skin problems. It's not typically recommended for use in managing fecal incontinence.
Choice D Reason:
Place a moisture barrier ointment over the perineal area is correct. Using a moisture barrier ointment can help protect the skin from irritation and breakdown caused by prolonged exposure to fecal matter, reducing the risk of skin breakdown and discomfort.
Correct Answer is A
Explanation
Choice A Reason:
Removing 45 mL of urine from the catheter with a syringe is correct. To obtain a sterile urine specimen from an indwelling urinary catheter, the nurse should use a sterile syringe to aspirate a specific volume of urine from the catheter tubing. This method ensures minimal contamination and an accurate representation of the urine in the bladder at that moment.
Choice B Reason:
Clamping the catheter tubing for 60 min is incorrect.
Clamping the catheter tubing can lead to potential complications such as urinary retention, backflow of urine, or discomfort for the client. It's not a standard practice and could compromise the client's care.
Choice C Reason:
Clamping the catheter tubing below the needleless port is incorrect.
Clamping the catheter tubing can disrupt the urinary drainage and potentially cause issues like urinary stasis or increase the risk of infection. It's not an appropriate method for collecting a sterile urine specimen.
Choice D Reason:
Place the specimen in a clean specimen cup is incorrect. While placing the specimen in a clean cup is necessary, the method of collecting a urine sample from an indwelling catheter involves using a sterile syringe to aspirate a specific volume of urine directly from the catheter tubing, rather than pouring it into a cup from the collection bag.
