Which of the following statements accurately reflects the relationship between obesity and surgical risk?

A. Lubricating the suction catheter tip with sterile saline is generally not recommended. The catheter tip is usually not lubricated before suctioning. Instead, suctioning should be performed using a dry, sterile catheter to prevent introducing any substances into the airway that could cause irritation or infection.
B. Hyperoxygenating the patient with 100% oxygen before suctioning is a crucial step. This helps to prevent hypoxia during the suctioning procedure, as suctioning can temporarily reduce the oxygen levels in the blood. By providing 100% oxygen for 30 to 60 seconds, the nurse ensures that the patient has an adequate oxygen reserve and reduces the risk of oxygen desaturation during suctioning.
C. Performing chest physiotherapy is not a routine pre-suctioning action and is generally done as part of a separate management strategy for clearing secretions. Chest physiotherapy involves techniques such as percussion, vibration, and postural drainage to help mobilize secretions from the lungs.
D. Instilling normal saline into the airway before suctioning (known as “normal saline lavage”) is not recommended. This practice can actually cause harm, such as increasing the risk of infection, causing bronchospasm, and diluting secretions which may then become more difficult to suction.

A. Petroleum-based products should not be used in conjunction with oxygen therapy. They are flammable and can pose a fire hazard when used near oxygen. Instead, use water-based moisturizers to prevent dryness of the lips and skin.
B. Wool and other synthetic fabrics can generate static electricity, which is a fire hazard when using oxygen
therapy. It’s safer to use cotton blankets, as they are less likely to cause static buildup.
C. Oxygen tanks should be stored upright to prevent them from falling over and to ensure the regulator and valves are properly aligned. Storing tanks upright helps maintain stability and prevents accidental damage to the equipment.
D. While the recommendation to keep oxygen tanks away from electrical sources is important, the distance may vary based on specific guidelines. It is generally advised to keep oxygen tanks at least 5-10 feet away from electrical sources and heat sources to avoid any risk of ignition or fire.
