A nurse is caring for a client who has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?
Continuous bubbling in the water-seal chamber
Occasional bubbling in the water-seal chamber
Fluctuations in the fluid level in the water-seal chamber
Constant bubbling in the suction-control chamber
The Correct Answer is A
Choice A Reason: Continuous bubbling in the water-seal chamber indicates an air leak in the chest tube system, which can compromise the drainage of air and fluid from the pleural space and impair lung expansion.
Choice B Reason: Occasional bubbling in the water-seal chamber is normal and expected, as it indicates that air is being removed from the pleural space.
Choice C Reason: Fluctuations in the fluid level in the water-seal chamber are normal and expected, as they reflect changes in intrathoracic pressure during inspiration and expiration.
Choice D Reason: Constant bubbling in the suction-control chamber is normal and expected, as it indicates that suction is being applied to the chest tube system.

Correct Answer is D
Explanation
Choice A: Eliciting the gag reflex is a way to assess cranial nerve IX (glossopharyngeal) and X (vagus), which are responsible for the sensation and motor function of the pharynx and larynx.
Choice B: Testing visual acuity is a way to assess cranial nerve II (optic), which is responsible for the sense of vision.
Choice C: Observing for facial symmetry is a way to assess cranial nerve VII (facial), which is responsible for the motor function of the facial muscles and the sensation of taste.
Choice D: Checking the pupillary response to light is a way to assess cranial nerve III (oculomotor), which is responsible for the motor function of most of the eye muscles, including those that control pupil size and lens shape.

Correct Answer is A
Explanation
Choice A Reason: This is correct because using log rolling to reposition the client helps maintain the alignment of the head and neck, which prevents further increases in ICP.
Choice B Reason: This is incorrect because placing a warming blanket on the client can cause vasodilation and increase cerebral blood flow, which can raise ICP.
Choice C Reason: This is incorrect because instructing the client to cough and deep breathe can increase intrathoracic pressure and impede venous return, which can elevate ICP.
Choice D Reason: This is incorrect because placing the client in a supine position can decrease cerebral perfusion pressure and increase ICP. The client should be placed in a semi-Fowler's position with the head elevated at 30 degrees.
