A nurse is caring for a client who has a small-bore jejunostomy tube and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?
Flush the tubing with 10 mL water every 6 hr.
Administer the feeding by gravity drip.
Replace the bag and tubing every 24 hr.
Heat the formula prior to infusion.
The Correct Answer is A
A. Flushing the tubing with water at regular intervals helps prevent the buildup of formula residue and maintains tube patency. This is especially important with high-viscosity formulas, which are more prone to clogging small-bore tubes.
B. Administering the feeding by gravity drip is a method of delivery and does not directly address the prevention of tubing clogging.
C. While replacing the bag and tubing every 24 hours is a standard practice to reduce the risk of bacterial contamination, it does not specifically prevent tubing clogging.
D. Heating the formula prior to infusion may improve its flow characteristics but does not address the prevention of tubing clogging. Heating formula should be done according to manufacturer guidelines to avoid denaturation of nutrients.
