The nurse is preparing a smoking cessation class for family members of patients with lung cancer. The nurse believes that the class will convert many smokers to nonsmokers once they realize the benefits of not smoking, Which health care model is the nurse following?

A) The nurse opens the top flap of a sterile tray toward the body when assisting the provider with a thoracentesis: This is incorrect technique. The sterile field should always be maintained, and when opening sterile trays, the nurse should open the flap away from the body to avoid contaminating the sterile field. Opening the flap toward the body increases the risk of contamination and compromises sterility, which is critical in maintaining aseptic technique during procedures.

B) The nurse uses clean gloves when discontinuing a client's intravenous infusion: Using clean gloves when discontinuing an intravenous infusion is appropriate. Clean gloves are sufficient for this non-sterile task, as the procedure does not involve direct contact with sterile body tissues or fluids. Sterile gloves are not necessary unless the task requires maintaining sterility, such as inserting a catheter.

C) The nurse uses the client's telephone number as one form of identification when administering medications to a client: This is a correct action, as the nurse is verifying the patient's identity before administering medication. It is important to use at least two identifiers (such as the patient's name and date of birth or medical record number) to ensure accurate identification, and the patient's telephone number can be an additional form of identification.

D) The nurse empties the client's drainable colostomy pouch when it is one third full: This is an appropriate action. The nurse should empty the colostomy pouch when it is one third to one half full to prevent leakage or discomfort. This action is part of proper colostomy care and helps maintain hygiene and comfort for the patient.

A) It is a good idea to use the handrails in the bathroom: This statement indicates a correct understanding of fall prevention. Handrails in bathrooms help provide stability and support, especially when getting in and out of the shower or bathtub. They are an essential safety feature to reduce the risk of falls in areas where slipping is more likely, such as wet or slippery bathroom floors.

B) "I should get a longer cord for my telephone": While this may seem like a way to improve accessibility, a longer telephone cord could actually increase the risk of tripping or entangling, especially if it is placed in a walking path. Keeping cords short and secured out of walking areas is a better fall prevention strategy.

C) "I should place a throw rug over electrical cords": Placing a throw rug over electrical cords creates a hazard rather than preventing falls. The rug could slip, and the cord may create a tripping hazard, which increases the risk of falls. It's important to secure cords and avoid placing them in areas where people walk.

D) "I should use chairs without armrests": Chairs without armrests may actually be less supportive for individuals with mobility issues, as armrests can provide extra stability when sitting down or standing up. It is better to use chairs that offer support, including armrests, to help prevent falls. The focus should be on ensuring that chairs are stable and easy to use, not eliminating armrests.
