Explanation:
During systole, the ventricles of the heart contract, which causes blood to be pumped out of the heart and into the aorta and pulmonary arteries. This is the phase of the cardiac cycle when the heart is actively contracting to push blood out of the ventricles and into the circulatory system.
Explanation:
The third precordial inspection landmark is the left sternal border (LSB) in the third to fifth intercostal spaces (ICS). This location corresponds to the location of the right ventricle of the heart.
Explanation:
The first landmark in precordial assessment is the right sternal border (RSB) at the second intercostal space (ICS). This location corresponds to the aortic valve, which is one of the four heart valves that regulate blood flow through the heart.
Explanation:
Unilateral jugular distension may indicate a local obstruction of the jugular vein. The jugular veins are located in the neck and are responsible for draining blood from the head and neck and returning it to the heart.
Explanation:
Bruits are sounds that can be heard over arteries when blood flow is turbulent, and they may indicate the presence of occlusive artery disease, also known as peripheral arterial disease (PAD).
Explanation:
A pulsation at the left sternal border (LSB) in the third to fifth intercostal spaces (ICS) may indicate right ventricular overload.
