A nurse is admitting a client who has pertussis. Which of the following types of transmission-based precautions should the nurse initiate?

A) Allow the client to rest for 10 to 15 seconds after each suctioning attempt: Allowing the client to rest between suctioning attempts helps to minimize hypoxemia and reduces the risk of trauma to the airway mucosa. It also allows the client to recover from the physiological stress of suctioning before initiating another attempt.

C) Apply suction for less than 10 seconds: Prolonged suctioning can lead to hypoxemia and tissue trauma. The nurse should limit suctioning to less than 10 seconds per pass to minimize these risks and prevent complications such as mucosal damage and bleeding.

B) Set the suction pressure to 110 mm Hg: The appropriate suction pressure for endotracheal suctioning depends on various factors, including the client's age, condition, and clinical status. While suction pressures of 80 to 120 mm Hg are commonly used for adults, the specific pressure setting should be individualized based on the client's needs and should not exceed the safe range to prevent mucosal injury or hypoxemia.

D) Apply suction when inserting the catheter: Suction should be applied only during withdrawal of the catheter to minimize the risk of mucosal trauma and hypoxemia. Applying suction during catheter insertion can increase the risk of airway trauma and should be avoided.

A. Chocolate milk:
Chocolate contains caffeine, which can contribute to sleep disturbances. It is not a recommended beverage for someone looking to decrease caffeine intake.

B. Diet cola:
Cola contains caffeine, even in diet versions, which can contribute to sleep disturbances. Therefore, it is not suitable for decreasing caffeine intake.

C. Brewed iced tea:
Brewed iced tea contains caffeine, which can interfere with sleep. It is not a suitable option for someone trying to reduce caffeine consumption.

D. Lemon-lime soda:
Lemon-lime sodas typically do not contain caffeine, making them a better choice for someone looking to reduce their caffeine intake and improve sleep.
