A nurse is planning to provide community education about viral hepatitis. Which of the following should the nurse plan to include in the teaching?

A. An air leak noted at the insertion site would result in continuous bubbling in the water seal chamber, not the absence of tidaling.

B. If the tubing is kinked or obstructed, it can prevent the movement of air in and out of the water seal chamber, leading to the absence of tidaling.

C. If water needs to be added to the suction-control chamber, this would affect the level of suction, not the tidaling in the water seal chamber.

D. If the suction is set too low, it would not necessarily affect the tidaling in the water seal chamber; instead, it would result in inadequate drainage or lack of suction.

A. A child who has a forehead wound that is bleeding copiously: While bleeding wounds require attention, they are not immediately life-threatening compared to other injuries described.

B. A child who has a compound fracture of the femur and is crying in pain: While painful, a

femur fracture is not typically immediately life-threatening unless it is causing severe bleeding or compromising circulation.

C. A child who reports diplopia and nausea and was unconscious at the scene but is now awake:

These symptoms suggest potential head trauma and require urgent evaluation to assess for intracranial injuries.

D. A child who has several missing permanent teeth and a swollen, ecchymotic upper lip: These injuries, while concerning, are not immediately life-threatening compared to the potential head injury described in option C.
