Problem 9 - Clinical Nursing Skills and Techniques

Question

The nurse is checking placement of a feeding tube of a patient who is receiving enteral medications. Which of the following techniques is correct in this situation? 1 The nurse attaches a \(20-\mathrm{mL}\) syringe to the tube and pulls back quickly while watching for facial grimacing. 2 The nurse places the patient flat in bed 30 minutes before checking for gastric residual volume. 3 The nurse attaches syringe and pulls the plunger slowly to obtain \(10 \mathrm{~mL}\) of gastric juice at least an hour after medications were given. 4 The nurse flushes the tube with \(60 \mathrm{~mL}\) of air through the syringe while watching for abdominal distention.

Step-by-Step Solution

Answer

Technique 3 is correct as it ensures proper tube placement by aspirating gastric contents to check their characteristics.

Step 1: Understanding the Objective

The task is to determine the correct technique for checking the placement of a feeding tube for a patient receiving enteral medications.

Step 2: Evaluating Technique 1

The first technique involves quickly pulling back a syringe while watching for facial grimacing. Using a syringe to aspirate stomach contents is correct, but observing for facial grimacing is not indicative of proper tube placement.

Step 3: Evaluating Technique 2

The second technique involves placing the patient flat in bed before checking gastric residual volume. Patients should not be placed flat when checking tube placement due to risk of aspiration.

Step 4: Evaluating Technique 3

The third technique involves slowly pulling the plunger to obtain gastric juice at least an hour after medications. This is appropriate as it allows for observation of aspirate characteristics, which can indicate proper placement.

Step 5: Evaluating Technique 4

The fourth technique involves flushing the tube with air and watching for abdominal distention. This is not a recommended method for checking tube placement as it does not provide reliable information.

Key Concepts

Gastric Residual Volume

Gastric residual volume (GRV) refers to the amount of gastric contents present in the stomach. Monitoring GRV is a crucial step in ensuring the safe administration of enteral feeding. The primary objective of checking the GRV is to prevent complications such as aspiration pneumonia. If too much residual is found, it indicates that the stomach is not emptying correctly, which can be a sign that feeds or fluids need to be delayed.

Regular checks of gastric residuals help healthcare providers make informed decisions about continuing, holding, or adjusting the feeding regimen. It's important to note that excessive residual volumes could lead to feed intolerance and increase the risk of regurgitation.

This monitoring typically involves withdrawing stomach contents using a syringe connected to the feeding tube. The GRV is then measured, and if an excessive amount is present, it may be discarded or reinstilled based on the established protocol of the healthcare facility.

Aspirate Characteristics

The characteristics of aspirated stomach contents are valuable indicators of correct feeding tube placement. When a feeding tube is inserted, confirming that the tube is correctly positioned in the stomach rather than the lungs or esophagus is essential.

Aspirate characteristics include color, consistency, and pH. Typically, gastric aspirates are greenish-yellow or clear with mucus, while intestinal fluid is darker and bile-like. A pH test can also aid verification, as gastric aspirates usually have a pH of 1 to 5.

By pulling a small amount of gastric content through the tube with a syringe, healthcare providers can examine these characteristics to confirm tube placement before administering feeds or medications.

Patient Positioning

Proper patient positioning during enteral feeding or when assessing feeding tube placement is crucial to prevent complications. When checking for gastric residual volume or positioning a feeding tube, the patient should be positioned with the head of the bed elevated at least 30 to 45 degrees.

This upright position helps reduce the risk of aspiration, a serious complication where stomach contents could enter the lungs. Lying flat is not advisable as it increases the potential for aspiration and other complications. The semifowler position is typically recommended for patients receiving enteral feeding, ensuring both comfort and safety.

Managing patient positioning effectively can significantly enhance the safety of enteral feeding practices.

Nursing Techniques

Nursing techniques for managing enteral feeding involve a combination of skills and knowledge to ensure safe and effective feeding practices. For checking feeding tube placement, it's important that nurses use syringes correctly to aspirate stomach contents gently and assess their characteristics.

Good nursing practice involves careful monitoring of the patient's response to feeding. This includes watching for signs of discomfort, ensuring the tube is not causing irritation, and regularly checking the tube's placement. A step-by-step approach, like slowly pulling the syringe's plunger, helps obtain accurate samples for testing aspirate characteristics.

Moreover, adequate communication skills are crucial, as nurses must inform and educate patients about procedures and any potential complications. By applying thoughtful and precise techniques, nurses play a vital role in the patient's overall care and comfort during enteral feeding.
