Assessment Flashcards

Bruits suggest:

Answer: Occlusive Artery Disease

A bruit is an abnormal sound heard through a stethoscope, typically over an artery, indicating turbulent blood flow. This turbulence is most commonly caused by a partial obstruction or narrowing of the artery, such as that seen in occlusive artery disease (e.g., atherosclerosis). The sound is created as blood rushes past the narrowed segment.

Pulsation at the third to fifth ICS in the LSB could mean

Answer: R ventricular overload

The third to fifth intercostal space (ICS) along the left sternal border (LSB) is a common location to palpate for right ventricular activity. A prominent or sustained pulsation in this area can indicate right ventricular hypertrophy or dilation, which is often a sign of right ventricular overload. This overload can be caused by conditions like pulmonary hypertension or tricuspid regurgitation.

Blood flows into the aorta and pulmonary arteries as the ventricles contract.

Answer: Systole

Systole is the phase of the cardiac cycle when the heart muscle contracts and pumps blood from the ventricles into the arteries. Specifically, ventricular systole involves the contraction of the left ventricle, ejecting blood into the aorta, and the right ventricle, ejecting blood into the pulmonary artery. This contraction phase is responsible for circulating blood throughout the body and to the lungs.

Jugular distension on one side alone could mean

Answer: Local obstruction of jugular vein

Unilateral jugular venous distension (JVD) indicates a localized problem affecting only one side of the neck. Systemic issues like impaired cardiac output or right-sided heart failure would typically cause bilateral JVD, as they affect overall venous return. Therefore, a local obstruction, such as a tumor or thrombosis, within that specific jugular vein is the most plausible cause for distension on one side only.

The first significant point in the precordial evaluation.

Answer: RSB second ICS

The precordial evaluation, particularly auscultation, typically begins by assessing the aortic area. This anatomical landmark is located at the right sternal border (RSB) in the second intercostal space (ICS). Starting here allows for a systematic and standardized approach to listening for heart sounds and murmurs, beginning with the aortic valve.

Third landmark of the precordial inspection.

Answer: LSB 3rd to 5th ICS

Precordial inspection involves systematically examining the chest wall for pulsations and thrills. After inspecting the aortic (RSB 2nd ICS) and pulmonic (LSB 2nd ICS) areas, the third landmark is typically the left sternal border (LSB) from the 3rd to the 5th intercostal space. This region corresponds to the tricuspid area, which is crucial for assessing right ventricular activity and tricuspid valve function.

A stoppage or delay in the heart's regular electrical conduction.

Answer: Heart block

Heart block refers to a condition where the electrical signals that control the heart's rhythm are partially or completely interrupted. This interruption occurs in the conduction pathway between the atria and ventricles, leading to a delay or complete stoppage of the regular electrical impulses. This definition directly describes the mechanism of a heart block.
