During the preoperative period, what is the nurse's responsibility regarding informed consent?

A. Using the same IV catheter for a second insertion attempt is not advisable. Once an IV catheter has been inserted, it should not be reused or reinserted in the same or a different site. If the initial insertion fails or if the catheter needs to be repositioned, a new sterile catheter should be used.
B. If there is any suspicion of contamination during the insertion of an IV catheter, it is important to replace the catheter to prevent infection. This is crucial for maintaining sterility and reducing the risk of introducing pathogens into the patient’s bloodstream.
C. The IV catheter should be removed once the course of IV antibiotics or any other IV therapy is completed, unless there is a specific medical reason to keep it in place. Leaving the catheter in place unnecessarily increases the risk of infection and other complications.
D. Disconnecting the IV infusion for a client to use the restroom is not typically recommended as a standard practice. Disconnecting can introduce risks of infection and requires thorough cleaning and handling. Instead, a safer practice is to secure the IV line and allow the client to use the restroom while keeping the infusion running, or use a specialized catheter with a secure, closed system.

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.
