What type of lubricant is recommended for use on the suction catheter?

The recommended lubricant for use on the suction catheter is a sterile water-soluble lubricant. This type of lubricant is safe for mucous membranes and does not cause irritation or adverse reactions when used in sensitive areas, such as the airway during suctioning.

Using a sterile water-soluble lubricant also ensures that the suction catheter can be easily inserted and moved without difficulty, aiding in effective suctioning. The sterile nature of the lubricant is crucial to prevent introducing bacteria or contaminants into the airway, thereby reducing the risk of infection.

Other options, such as oil-based lubricants, can pose risks when used in respiratory care as they may coat and potentially damage the lungs if aspirated. Non-sterile lubricants are not appropriate in clinical settings where maintaining sterile techniques is essential to patient safety and outcome. Therefore, the best choice adheres to the principles of infection control and patient comfort.
