Question

A nurse educator is reviewing the sue of cardiopulmonary bypass during surgery for CABG with a group of nurses. Which of the following statements should the nurse include in the discussion? (Select all that apply.)

A. "The client's demand for oxygen is lowered."
B. "Motion of the heart ceases."
C. "Rewarming of the client takes place."
D. "The client's metabolic rate is increased."
E. "Blood flow to the heart is stopped."

Answer 1

During CABG surgery, cardiopulmonary bypass is used to maintain circulation. Rewarming the client after controlled hypothermia is important, but blood flow to the heart is actually stopped during the procedure.

Step-by-step explanation:

During surgery for coronary artery bypass graft (CABG), cardiopulmonary bypass is used to maintain circulation to the patient's body. The process involves stopping the heart and using an external heart-lung pump to maintain blood flow. One of the key steps in the process is rewarming the client after controlled hypothermia to minimize the risk of damage to the brain, heart, and other organs. So, the statement 'Rewarming of the client takes place' is correct.

However, the statement 'Blood flow to the heart is stopped' is incorrect. In fact, the purpose of cardiopulmonary bypass is to bypass the heart and lungs temporarily, allowing the surgeon to perform the CABG procedure on a motionless and bloodless heart. The blood flow to the heart is maintained through the bypass machine, which performs the function of the heart and lungs.
