Which explanation would the nurse give to the spouse of a client who had coronary artery bypass graft (CABG) surgery when asked why there is a dressing on the client's left leg?
A vein in the leg was used to bypass the coronary artery.
A filter is inserted in the leg to prevent embolization.
The arteries in the extremities are examined during surgery.
This is the access site for the heart-lung machine.
The Correct Answer is A
A. A vein in the leg was used to bypass the coronary artery: During CABG surgery, the saphenous vein from the leg is commonly harvested to create a graft that bypasses blocked coronary arteries. The leg dressing protects the incision site, prevents infection, and promotes healing after vein harvesting.
B. A filter is inserted in the leg to prevent embolization: Inferior vena cava (IVC) filters are sometimes placed to prevent pulmonary embolism, but this is unrelated to CABG surgery. There is no routine filter insertion in the leg during bypass surgery.
C. The arteries in the extremities are examined during surgery: Although vascular assessment may occur, the leg is not routinely opened for examination of arteries during CABG. The incision is specifically for vein harvesting rather than diagnostic assessment.
D. This is the access site for the heart-lung machine: The heart-lung machine typically connects via central vessels such as the aorta and right atrium, not through the leg. The leg incision is unrelated to cardiopulmonary bypass access.

Explanation
Aortic area: Aortic Stenosis.
Key findings:
- Orthopnea
- Peripheral cyanosis
- Narrow pulse pressure
These are classic findings of Aortic Stenosis.
- Obstruction of left ventricular outflow
- Decreased stroke volume
- Narrow pulse pressure (low systolic output)
- Pulmonary congestion - orthopnea
- Poor systemic perfusion - cyanosis
The best auscultation Site is the 2nd intercostal space, right sternal border
(Aortic valve area)
It is typically: Harsh, systolic and may radiate to the carotid arteries
Correct Answer is B
Explanation
A. The rhythm strip shown in A exhibits a regular underlying rhythm interrupted by a Premature Ventricular Contraction (PVC), which is a wide, bizarre QRS complex occurring earlier than expected. While PVCs can cause palpitations, they do not typically present as a sustained "rapid, irregular" heart rate with a total absence of P-waves across the entire strip.
B. The rhythm strip in B represents Atrial Fibrillation (AFib), characterized by a "normally irregular" ventricular response and the replacement of distinct P-waves with chaotic fibrillatory waves. In AFib, the atria quiver rather than contract, leading to a significant pulse deficit because not every electrical impulse results in a ventricular contraction strong enough to produce a peripheral pulse.
