Free Cardiac Surgery Sample Questions and Answers — Questions and Answers
Question 1: A pacemaker is a device that produces electrical impulses that stimulate the heart. This process is called _____________.
- Pacing the heart (Correct answer)
- Pulmonary veins into the left atrium
- Internal mammary artery
- Stabilizing the heart
Correct answer: Pacing the heart
The process of producing electrical impulses that stimulate the heart using a pacemaker is called "pacing the heart."
Question 2: Suture annuloplasty, ring annuloplasty, and valve replacement with either a biologic or mechanical prosthesis are a few of the treatments available for tricuspid valve disease. The tricuspid annulus is saddle-shaped, much like the mitral valve, and procedures to repair the valve should take its anatomical arrangement into account. Patients who have severe regurgitation, tricuspid stenosis, or a failed tricuspid (suture or ring) annuloplasty may need to have a prosthetic biologic or mechanical valve implanted. What kind of prosthetic graft would be made or placed as there are no specialized prosthetic tricuspid valves available?
- Ischemia
- 40-60
- Mitral valve and then the left ventricle
- Mitral prosthesis (Correct answer)
Correct answer: Mitral prosthesis
When there are no specific tricuspid prosthetic valves available, the preferred approach for replacing the tricuspid valve is to use a mitral prosthesis. The mitral prosthesis is designed for the mitral valve, which is similar to the tricuspid valve in terms of anatomy and function. Therefore, in the absence of dedicated tricuspid prosthetic valves, a mitral prosthesis is commonly used as a substitute in cases where tricuspid valve replacement is required. The mitral prosthesis is modified and implanted in the tricuspid position to restore the valve function.
Question 3: What are the two classifications of aneurysm?
- Saccular Aneurysm
- Saccular and Fusiform (Correct answer)
- Cranial and Caudal
- Aortic and Ventricular
Correct answer: Saccular and Fusiform
Aneurysms are classified by shape into saccular (a pouch-like outpouching on one side of the vessel) and fusiform (a diffuse, spindle-shaped dilation around the whole circumference). The other pairings either name only one type or use anatomical terms that aren't standard aneurysm shape classifications.
Question 4: The #11 knife blade is used to cut open the coronary artery (or Beaver blade), and the incision is extended with Dietrich or fine _______ coronary scissors.
- Penfield
- Lowman
- Potts (Correct answer)
- Allen
Correct answer: Potts
The correct term to complete the sentence is "Potts." The incision made in the coronary artery with a #11 knife blade is extended using Dietrich or fine Potts coronary scissors. Potts coronary scissors are a specific type of surgical scissors designed for delicate dissection and cutting in cardiovascular procedures, including coronary artery surgeries. They are commonly used in cardiac surgery to precisely extend the incision in the coronary artery for various interventions, such as bypass grafting or other procedures involving the coronary arteries.
Question 5: A quick heartbeat called a tachycardia, usually more than ________ beats per minute.
- 100
- 120 (Correct answer)
- 180
- 110
Correct answer: 120
Tachycardia is a fast heart rate, usually defined as a heart rate of more than 100 beats per minute. Therefore, it is typically considered tachycardia when the heart rate exceeds 100 beats per minute, rather than 120 beats per minute as stated in your response. However, it's important to note that the specific heart rate threshold to classify tachycardia may vary depending on factors such as age, underlying health conditions, and the context in which it occurs.
Question 6: Cardiac catheterization is an ___________ procedure and entails inserting a cardiac catheter through a peripheral artery or vein into the heart chambers and major arteries.
- Radiographic positioning
- Interventional radiology (Correct answer)
- Magnetic resonance imaging (MRI)
- Median
Correct answer: Interventional radiology
Cardiac catheterization is an interventional radiology procedure because it uses real-time imaging (fluoroscopy) to guide a catheter through a vessel into the heart, combining imaging with a minimally invasive intervention. Radiographic positioning and MRI are purely diagnostic imaging methods that don't involve threading catheters into the heart, and 'median' is not a procedure type at all.
Question 7: Removal of the native heart and replacement with a donor heart is indicated for patients with ______ cardiac disease.
- End-stage (Correct answer)
- Systole
- Transverse
- Endocardium
Correct answer: End-stage
The removal of the native heart and replacement with a donor heart, also known as heart transplantation, is indicated for patients with end-stage cardiac disease. End-stage cardiac disease refers to advanced and irreversible damage to the heart, where conventional medical therapies are no longer effective in managing the condition. In such cases, heart transplantation may be considered as a treatment option for improving the patient's quality of life and overall survival. The decision for heart transplantation is based on careful evaluation of the patient's medical history, current condition, and the availability of a suitable donor organ.
A pacemaker is a device that produces electrical impulses that stimulate the heart.
