The nurse monitors the client in the immediate hours following an anterior-lateral wall myocardial infarction for the development of:

A. Hyperglycemia:
Although hyperglycemia can occur as a result of stress or corticosteroid use during the treatment of GBS (such as in the case of plasma exchange or IV immunoglobulin (IVIG) therapy), it is not the primary complication associated with GBS. While hyperglycemia requires monitoring and management, respiratory failure is a more immediate and critical concern.

B. Urinary retention:
Urinary retention can occur in some clients with neurologic disorders like GBS, but it is not as life-threatening as respiratory failure. The autonomic nervous system, which controls bladder function, may be affected, but urinary retention is usually manageable with intermittent catheterization or other interventions. It does not carry the same immediate risks to life or organ function as respiratory failure.

C. Respiratory failure:
In Guillain-Barré syndrome (GBS), the immune system attacks the peripheral nervous system, which can lead to progressive muscle weakness and paralysis. The most significant and potentially life-threatening complication of GBS is respiratory failure. This occurs because the paralysis can affect the muscles involved in breathing, including the diaphragm and intercostal muscles, leading to impaired ventilation. As the weakness progresses, the client may become unable to maintain effective breathing, requiring mechanical ventilation. Monitoring for signs of respiratory distress (e.g., increasing work of breathing, tachypnea, decreased breath sounds, or a drop in oxygen saturation) is critical in GBS, especially during the acute phase of the disease.

D. Hypertension:
Hypertension may be seen in some cases of GBS, particularly during the early stages of the disease, due to the autonomic dysfunction that can result from nerve involvement. However, hypotension (low blood pressure) is more commonly associated with the autonomic dysfunction in GBS rather than hypertension. Regardless, respiratory failure remains the most urgent complication to monitor for in clients with GBS.

A. There is continuous bubbling in the water-seal chamber: Continuous bubbling in the water-seal chamber suggests a potential air leak in the system, which needs to be investigated. The water-seal chamber is designed to prevent backflow of air into the pleural space, and persistent bubbling typically indicates that air is escaping from the pleural cavity or there is a problem with the tubing or chest tube placement. This is the first sign that the system may not be sealed properly and should be checked for leaks.

B. The water levels in the water-seal chamber and suction chambers are decreased: Decreased water levels in both the water-seal and suction chambers may be indicative of fluid loss or evaporation, but it does not necessarily point to a leak. In the case of a chest tube, water levels may also drop due to suction pressure or gradual evaporation, which would need to be adjusted or monitored. While this should be addressed, it is not an immediate cause for suspicion of an air leak in the system.

C. Fluid in the water-seal chamber fluctuates with the client's breathing: The fluctuation (also known as "tidaling") in the water-seal chamber is a normal finding that occurs when the client breathes in and out. It reflects the pressure changes in the pleural cavity during respiration. The absence of tidaling might indicate that the lung has re-expanded or that there is a blockage in the tubing. While tidaling is a normal occurrence, the absence or abnormality of this fluctuation would require further assessment but not for an air leak.

D. There is constant bubbling in the suction-control chamber: Constant bubbling in the suction-control chamber generally indicates that suction is appropriately applied to the system. However, if there is continuous bubbling in this chamber, it is typically related to the level of suction being applied, not an air leak. This is a normal occurrence and does not require checking for leaks in the system unless suction pressure is too high or low for optimal functioning.
