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.

Answer and Explanation

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 A

Explanation

Choice A rationale

Keeping elbows slightly bent when grasping the walker helps to maintain stability and control. This positioning reduces the strain on the arms and shoulders, providing a more comfortable and effective way to use the walker.

Choice B rationale

Sliding the walker and moving it about a foot in front can cause instability. Instead, lifting the walker and placing it step-by-step ensures better support and reduces the risk of falls.

Choice C rationale

Moving the walker and the stronger leg at the same time can lead to imbalance and falls. The correct method is to move the walker first, then step forward with the weaker leg, followed by the stronger leg.

Choice D rationale

Keeping the walker height adjusted so the user leans slightly forward is incorrect. The walker height should be at the level of the wrists when the arms are hanging down, allowing for a natural and upright posture.

A. Place one hand over the other against the part of the gown covering their upper body. B. Clasp their hands together in a relaxed position behind their body at their waist. C. Keep their arms at the sides of their body with their hands in a relaxed position. D. Interlock their fingers and hold their hands away from their body above their waist.

Correct Answer is D

Explanation

Choice A rationale

Placing one hand over the other against the upper body of the gown increases the risk of contamination. The sterile field must be maintained by keeping hands in a position where they are less likely to come into contact with non-sterile surfaces.

Choice B rationale

Clasping hands behind the body at the waist can also lead to contamination, as the hands may inadvertently touch the gown, which may not be sterile in that area. It’s essential to keep hands in a position where they are less likely to become contaminated.

Choice C rationale

Keeping arms at the sides with hands in a relaxed position might cause hands to brush against non-sterile surfaces or clothing, leading to contamination. Therefore, this position is not recommended for maintaining sterility.

Choice D rationale

Interlocking fingers and holding hands away from the body above the waist is the proper technique for maintaining sterility. This position ensures that the hands are kept in the sterile field and away from non-sterile surfaces, reducing the risk of contamination.
