Study Notes
Assessment Techniques
- Palpate carotid arteries individually to avoid reducing cerebral blood flow; auscultate before palpation.
- Auscultate heart sounds while determining heart rate and rhythm; use the diaphragm for high-pitched sounds.
- Modify client positioning to enhance auscultation and ensure accurate readings.
Cardiac Anatomy
- Semilunar valves are located at the exit of each ventricle, beginning the great vessels.
- The bicuspid (mitral) valve is between the left atrium and left ventricle.
- Aortic and pulmonic valves closure creates the second heart sound (S2).
Cardiac Output Norms
- Normal cardiac output ranges from 5-8 L/min; 6 L/min is considered within this range.
- Bradycardia is defined as a heart rate lower than 60 beats per minute; tachycardia is above 100 beats per minute.
Heart Sounds and Abnormalities
- First heart sound (S1) results from closure of the atrioventricular valves, while the second (S2) from semilunar valves closure.
- S3 and S4 heart sounds together create a summation gallop, indicating heart failure or volume overload.
- Abnormal findings like a bruit indicate occlusive arterial disease; jugular venous distention suggests heart failure.
Risk Factors and Health Education
- Hypertension is more prevalent in African Americans; high serum levels of low-density lipoproteins increase coronary heart disease risk.
- Lifestyle measures for reducing coronary artery disease risk include stress management, regular walking, and low-sodium diets.
Monitoring and Intervention
- Frequent blood pressure monitoring is paramount with decreased cardiac output.
- Signs such as nocturia in clients can indicate heart failure due to increased renal perfusion during rest periods.
EKG Waveform Understanding
- The T wave signifies ventricular repolarization while the PR interval indicates the time from SA node firing to the onset of ventricular depolarization.
Client Interaction and Resources
- Encourage clients to keep food and activity logs to better manage hypertension and lifestyle choices.
- Provide resources for smoking cessation as a part of risk factor modification.
Physical Examination Techniques
- To hear a suspected pericardial friction rub, position the client upright and leaning forward.
- Engage in thorough assessments to understand signs like jugular vein distention thoroughly, indicating possible heart failure.
Overall Cardiac Health
- Educate clients about symptoms like dyspnea and nocturia as indicators of potential heart conditions.
- Reinforce the importance of maintaining regular health check-ups to monitor for cardiovascular risks and conditions.### Heart Sounds and Assessment
- Best position for auscultating a client's heart sounds is sitting up, leaning forward, exhaling, and holding breath.
- Left lateral position may be used to hear an S3 or S4 heart sound or a murmur of mitral stenosis not detected in supine position.
Grading Murmurs
- Grade 5 murmur: very loud, can be heard with stethoscope partly off chest.
- Grade 1 murmur: very faint.
- Grade 6 murmur: can be heard with stethoscope entirely off chest.
- Grade 2 murmur: quiet, heard immediately on placing stethoscope on chest.
Auscultation Technique
- Focus on one sound at a time when auscultating the precordium.
- Start by determining rate and rhythm.
- Stand at client's right side to perform assessment.
- Client should be lying in supine position with head of bed elevated at 30 degrees.
- Diaphragm of stethoscope used to listen for high-pitched sounds of normal heart sounds.
Heart Sounds Location
- S1 heart sound best heard at the apex (left MCL, fifth ICS).
- Pulmonic valve sounds heard best at second left interspace.
Angina
- Temporary heart pain, resolving in less than 20 minutes, aggravated by physical activity and stress.
ECG
- P wave indicates atrial depolarization (duration up to 80 msec; PR interval 120 to 200 msec).
Mitral Stenosis
- Listen with bell of stethoscope over apex with client on left side.
- Murmur has low-pitched, rumbling quality.
Heart Failure
- Edema in both lower extremities at night is seen in heart failure.
- Due to reduction of blood flow out of heart, causing blood to back up in organs and dependent areas of body.
Point of Maximum Impulse (PMI)
- If unable to identify PMI with client supine, assist client to roll partly onto left side or left lateral decubitus position.
Mitral Insufficiency
- S1 sound is diminished.
Lifestyle Modifications
- Regular exercise provides many benefits, including lowering risk of hypertension.
Dehydration
- Decrease in jugular venous pressure occurs with dehydration secondary to decrease in total blood volume.
Palpitations
- Palpitations may occur with abnormality of heart's conduction system or during heart's attempt to increase cardiac output by increasing heart rate.
S3 Heart Sound
- Caused by rapid deceleration of blood against the ventricular wall.
Accentuated S2
- S2 is louder than S1, occurring in conditions where aortic or pulmonic valve has higher closing pressure.
Ineffective Tissue Perfusion
- Characterized by weak radial pulse and decreased carotid pulses.
Mitral Valve Prolapse
- Midsystolic click is heard on auscultation.
Murmur Location
- Mitral valve sounds are usually heard best at and around cardiac apex.
ECG Waveforms
- T wave indicates ventricular repolarization.
- P wave indicates atrial depolarization.
- QRS complex indicates ventricular depolarization.
- ST segment indicates period between ventricular depolarization and beginning of ventricular repolarization.
Electrical Conduction System
- Electrical signal originates in sinoatrial node.
Precordium
- Anterior chest area that overlies heart and great vessels.
Semilunar Valves
- Located at exit of each ventricle at beginning of great vessels.
Murmur
- Swooshing or blowing sound caused by turbulent blood flow in heart.
Auscultation Technique
- Systematically listen to entire precordium, using diaphragm and bell.
Myocardial Infarction
- Treatment includes nitroglycerin, bedrest, thrombolytics, or angioplasty.
Stroke Volume
- Decreased left ventricular compliance causes decrease in stroke volume.
Jugular Venous Pressure
- Measures pressure in right atrium.
Right Atrial Pressure
- Engorged jugular veins are seen in right or left heart failure, pulmonary hypertension, tricuspid stenosis, and pericardial compression or tamponade.
Cardiac Structure and Function
- The semilunar valves are located at the exit of each ventricle at the beginning of the great vessels.
- The myocardium is the thickest layer of the heart, made up of contractile cardiac muscle cells.
Heart Sounds
- A split S1 occurs when the left and right ventricles contract at different times (asynchronous ventricular contraction).
- A thrill or pulsation is usually associated with a grade IV or higher murmur.
- An accentuated S1 sound is louder than an S2 sound, which occurs when the mitral valve is wide open and closes quickly (e.g., in hyperkinetic states or mitral stenosis).
- Crescendo-decrescendo murmur grows louder and then softer.
- The first heart sound corresponds to the closure of the atrioventricular valves.
- The second heart sound corresponds to the closure of the semilunar valves.
Electrocardiogram (ECG)
- The P wave indicates atrial depolarization and conduction of the impulse throughout the atria.
- The T wave indicates ventricular repolarization, when the ventricles return to a resting state.
Cardiac Examination
- When performing a cardiac examination, the nurse should:
- Instruct the client to wear the examination gown with the opening in the front.
- Have the client sit and lean forward for part of the examination.
- Have the client lay on their left side for part of the examination.
- The left lateral decubitus position brings the left ventricle closer to the chest wall, allowing mitral valve murmurs to be better heard.
Cardiac Pain
- Angina (cardiac chest pain) is usually described as a sensation of squeezing around the heart; a steady, severe pain; and a sense of pressure.
- It may radiate to the left shoulder and down the left arm or to the jaw.
- Cardiac pain may occur at any time, is not relieved with antacids, and worsens with activity.
Great Vessels
- The great vessels include the superior and inferior vena cava, the pulmonary artery and vein, and the aorta.
- The femoral artery is not a great vessel.
Dysrhythmias
- Sinus arrhythmia is a heart rate that speeds with inspiration and slows with exhalation.
- Atrial fibrillation causes the ventricles to beat irregularly.
- Premature ventricular contractions and premature atrial contractions occur earlier than expected.
Risk Reduction
- Quitting smoking can reduce the risk of cardiac events by 50% after the first year.
Auscultation
- Aortic stenosis is a midsystolic ejection murmur that begins after S1, crescendos, and then decrescendos before S2.
- It is best heard over the 2nd or 3rd right intercostal space.
- Jugular venous pressure (JVP) is a visible manifestation of the varying pressures in the right atrium.
- Palpating the carotid pulse while auscultating the heart can help distinguish S1 and S2 sounds.
Cardiovascular Assessment
- To assess for stenosis in the carotid arteries, the nurse should check for pulse inequality between the right and left carotid arteries.
- Differences in the amplitude or rate of the carotid pulse may indicate stenosis.
