Cardiac Assessment Flashcards
What sound can be heard during early diastole at the 3rd or 4th left interspacr at sternum border?
Opening snap, just after S2
= stenosis, increased higher atrial pressure
What is the sound associated between S1 and S2, and what does it indicate?
Midsystolic (Mitral) clock is associated with mitral valve prolapse.
During cardiac stress, tachycardia occurs. What sound is associated with this condition?
Summation sound = diastolic filling time shortens, S3 and S4 superimpose in mid-diastole
If an S2 Split is heard in both expirations and inhalation’s, but is wider during inspiration, it is called and indicates:
Wide split = right ventricle has delayed electrical activation
- R bundle branch block
What sound occurs mid- to late systole and is short and high pitched with a click quality?
Midsytolic (Mitral) Click = mitral valve prolapse
What does a lift (heave) indicate?
- R ventricular hypertrophy
- Pulmonic valve disease
- Pulmonic HTN
- Chronic lung disease
What sound is high pitched and scratchy and with breath held in expiration?
Pericardial Friction Rub
What are late diastole murmurs?
- Fourth heart sound (S4)
2. Pacemaker-induced sound
If a patient presents with varying intensity of S1, what could that be indicative of?
Atrial fibrillation
Complete heart block with changing PR interval
What could cause an accentuated S2?
- Higher closing pressure (systemic hypertension)
- Increased pressure in aorta (exercise or excitement)
- Pulmonary hypertension (mitral stenosis or heart failure)
- SL valves calcified but mobile (aortic or pulmonic stenosis)
If S3 persists when patient is sitting up, what is the sound called?
Ventricular gallop
What sound occurs due to volume overload, such as mitral/aortic/tricuspid regurgitation or high cardiac output?
S3
What nursing interventions prevent stasis of pulmonary secretions?
- Changing pt position every 2 hrs
- Increase fluids
- Chest physio (percussion and positioning)
What sound can be heard at both base and apex, just after S1 during early systole?
Aortic ejection click
What sound is heard best with the bell of the stethoscope at the apex and sounds soft and low pitched, like “distant thunder”?
S3 = ventricular filling
If a patient has delayed right ventricular electrical activation, what sound would be heard?
Wide S2 Split
What nursing interventions help reduce orthostatic hypotension?
- Early mobilization
2. Changing position slowly and gradually
Blood is detoured through _________ from the pulmonary artery to aorta
Ductus arteriosus - to bypass fetus’ lungs
What two sounds are heard during early systolic?
- Aortic ejection click at apex and base. Heard just after S1.
- Pulmonic ejection click. Heard just after S1, loud on expirations, at base only.
