The nurse is caring for a client status/post a Myocardial Infarction who is questioning procedures utilized for treatment. Which of the following statements correctly explains a Coronary Artery Bypass Grafting (CABG)?
A balloon will be inflated within the artery to open the blocked artery.
A medication will be given to dissolve the blood clot.
A dye will be injected to outline the vessels of the heart.
A healthy artery or vein will go around the blocked portion of the coronary artery.
The Correct Answer is D
A. A balloon inflation within the artery describes percutaneous coronary intervention (PCI) or angioplasty, not CABG.
B. A medication to dissolve a blood clot refers to thrombolytic therapy, which is not part of a CABG procedure.
C. Injecting dye to outline heart vessels describes a coronary angiogram, which is a diagnostic procedure but not a treatment.
D. CABG involves using a healthy artery or vein to bypass the blocked portion of a coronary artery, restoring proper blood flow to the heart muscle.

Correct Answer is C
Explanation
A. Immediately notify the provider . A rise in the water seal chamber with inspiration (tidaling) is a normal finding, indicating proper function of the chest drainage system. There is no need for immediate provider notification.
B. Clamp the chest tube near the water seal . Clamping the chest tube can lead to a tension pneumothorax by trapping air inside the pleural space. This action is only done temporarily for specific indications, such as assessing for an air leak or changing the drainage system.
C. Continue to monitor the client . Tidaling (fluctuation of water with inspiration and expiration) is expected in the water seal chamber. The nurse should continue to monitor for any sudden cessation of tidaling (which may indicate obstruction) or continuous bubbling (which may indicate an air leak).
D. Reposition the client toward the left side . Position changes do not affect normal tidaling in a functioning chest tube system. However, frequent repositioning is encouraged to promote lung expansion.
