Cardiothoracic Surgery Quiz

What is the purpose of cardiac surgery?

• To improve vision

• To restore blood flow to the heart

• To treat lung diseases

• To repair broken bones

What is the main function of the Cardiopulmonary Bypass (CPB) machine during cardiac surgery?

• To provide oxygen to the patient before surgery

• To administer anesthesia to the patient

• To cool down the patient's body temperature

• To temporarily take over the function of the heart and lungs

What is the primary reason for using cold cardioplegia during cardiac surgery?

• To produce myocardial hypothermia and protect against myocardial ischemia

• To prevent clotting in the blood vessels

• To increase blood pressure

• To speed up the heart rate

What are the sternal precautions that patients need to follow after cardiac surgery?

• Avoid using arms to get out of bed and lifting more than 2 kg

• Wear tight-fitting clothes

• Engage in heavy weightlifting exercises

• Bend forward as much as possible

What is the main complication of cardiac tamponade after cardiac surgery?

• Improved cardiac output

• Decreased heart rate

• Increased blood flow to the heart

• Compression of the heart due to fluid accumulation in the pericardial sac

What is the primary role of the Critical Care Nurse in postoperative care?

• Performing surgery, administering anesthesia, and monitoring vital signs

• Providing emotional support, cleaning the patient's room, and serving meals

• Assessment, restoration of cardiac output, and patient education

• Assisting with physical therapy, managing medications, and conducting lab tests

What are the physiological changes in the cardiovascular system of older patients after cardiac surgery?

• Improved cardiac function

• Enhanced ability to adjust to changes in blood volume

• Decreased heart rate and blood pressure

• Increased stiffness of myocardial muscle and peripheral vasculature

What is the main consideration for patient teaching in older patients after cardiac surgery?

• Provide complex information without repetition

• Accommodate sensory deficits and ensure understanding of information

• Avoid communication and limit patient involvement

• Use small print and complex language

What is the primary complication of hypovolemia after cardiac surgery?

• Improved kidney function

• Enhanced respiratory function

• Increased blood volume and hypertension

• Decreased blood volume leading to decreased cardiac output

What is the main role of the Critical Care Nurse in patient education after cardiac surgery?

• Monitor vital signs and document patient progress

• Administer medications and perform procedures

• Avoid patient education and focus only on medical care
