A nurse is checking for 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.
Check the pH level of gastric contents.
Auscultate for air insufflation.
Request a chest x-ray.
The Correct Answer is D
Choice A rationale
Verifying the bilirubin level of the tube contents is not a standard or reliable method for checking the placement of a feeding tube. Bilirubin is a bile pigment found in the liver and bile ducts, and its levels are not indicative of tube placement in the gastrointestinal tract.
Choice B rationale
Checking the pH level of gastric contents can help determine if the tube is in the stomach, but it is not the most reliable method. Gastric pH is typically acidic (1.5-3.5), but the pH can vary, and this method does not rule out respiratory placement or other incorrect placements.
Choice C rationale
Auscultating for air insufflation involves listening for the sound of air injected through the tube into the stomach. However, this method is not reliable as it does not confirm the exact location of the tube and can give false positives if the tube is in the esophagus or respiratory tract.
Choice D rationale
Requesting a chest x-ray is the most reliable method for verifying feeding tube placement. It provides a clear visual confirmation of the tube's location, ensuring it is correctly positioned in the stomach or small intestine and not in the respiratory tract or other incorrect locations.

Correct Answer is C
Explanation
Choice A rationale
A repressed grief response, where an individual avoids expressing their grief, is considered delayed grief, not exaggerated grief. This can manifest as physical symptoms or psychological issues later on.
Choice B rationale
Grief that begins following a terminal diagnosis is anticipatory grief, which is a normal response as individuals begin to process the impending loss. It prepares them emotionally for the eventual death.
Choice C rationale
Exaggerated grief involves intense, prolonged, and often harmful reactions such as self-destructive behaviors. This type of grief can significantly impair a person's ability to function and may require professional intervention.
Choice D rationale
A grief response triggered by a secondary loss (e.g., loss of job or home) is known as cumulative grief. While it complicates the grieving process, it does not inherently lead to the exaggerated, self-destructive behaviors seen in exaggerated grief.
Correct Answer is D
Explanation
Choice A rationale
Cleaning the hearing aid with isopropyl alcohol is not recommended as it can damage the device. Proper cleaning methods involve using specialized cleaning tools and gentle cleaning solutions.
Choice B rationale
Turning the hearing aid off for 5 minutes is not likely to resolve the whistling sound, which is often caused by feedback issues that need to be addressed through other means such as adjusting the fit or volume.
Choice C rationale
Soaking the hearing aid in warm water is inappropriate and can cause irreparable damage. Hearing aids are electronic devices and should not be submerged in water.
Choice D rationale
Decreasing the volume on the hearing aid can help reduce the whistling sound, which is commonly caused by feedback. Proper fitting and volume adjustments are key to preventing this issue.
