Cardiovascular

Assessment Details

  • Perform a focused assessment:

    • Begin by introducing yourself and stating your title.

    • Ensure your name badge is visible to the client.

    • Use standard precautions; practice appropriate handwashing.

    • Assess one area at a time for client comfort and modesty.

Environment

  • Create a Suitable Assessment Environment:

    • Ensure the surroundings are quiet to facilitate accurate auscultation.

Vital Signs

  • Vital Signs Importance:

    • Measure pulse, respirations, blood pressure, oxygen saturation.

    • These indicators are vital for assessing the client's oxygenation and perfusion status.

    • Review expected/unexpected findings for vital signs in the general survey module.

Assessment Techniques

  • Cardiovascular Assessment Techniques:

    • Learn inspection, palpation, and auscultation of the cardiovascular system (heart and peripheral blood vessels).

    • Also assess respiratory status (e.g., breathing effort).

    • Note that unexpected cardiovascular findings may present as respiratory symptoms (e.g., shortness of breath in heart failure).

    • Include integumentary system assessment: skin color, presence of edema or moisture as indicators of cardiovascular compromise.

Skin Assessment Overlap

  • Skin Assessment's Role in Cardiovascular Health:

    • Review the skin module for relevant cardiovascular components.

    • Document findings according to facility policy for the care plan and interventions.

    • Clear, precise, timely documentation is essential for healthcare team members to communicate effectively.

Reporting Findings

  • Management of Unexpected Findings:

    • Report any unexpected findings promptly to the client's provider.

Tools for Assessment

  • Essential Tools Needed:

    • Stethoscope: utilized for heart and vessel auscultation.

      • Clean diaphragm and bell with alcohol before each use.

      • Diaphragm: best for high-pitched sounds, resp, and heart sounds.

      • Bell: best for softer sounds like murmurs.

    • Doppler: ultrasonic tool for assessing pulses; detects weak pulses by amplifying sound.

    • Watch/Clock: for counting apical pulse over one full minute.

    • Pinlight: to visualize pulsations in neck vessels.

Blood Flow Through the Heart

  • Circulation Mechanics:

    • Blood flow is a continuous loop:

      • Deoxygenated blood returns to the heart via inferior/superior vena cava to the right atrium.

      • Diastolic phase: AV valves open; blood flows to right ventricle through tricuspid valve.

      • Systolic phase: ventricular contraction; blood ejects through pulmonic valve to the pulmonary arteries for oxygenation.

      • Oxygenated blood returns to the left atrium via pulmonary veins during diastole, flows through mitral valve to left ventricle.

      • With contraction, blood is propelled through aortic valve into the aorta.

      • Heart Structure: roughly the size of a closed hand, located slightly left of the chest center.

    • PMI (Point of Maximal Impulse): occurs at the apex during ventricular contraction; typically located at the left fifth intercostal space.

Heart Anatomy

  • Heart Layers:

    • Pericardium: fibrous connective tissue sac protecting the heart.

    • Myocardium: thick muscular layer contracting to pump blood.

    • Endocardium: innermost layer lining the heart and blood vessels.

Heart Chambers and Their Functions

  • Chambers:

    • Four sections: two atria (upper chambers) and two ventricles (lower pumping chambers).

  • Circulation Process:

    • Atria collect blood; ventricles pump blood to lungs and the body.

Valves in the Heart

  • Valve Types:

    • Atrioventricular Valves (AV): control blood flow between atria and ventricles (tricuspid and bicuspid). Open during filling (diastole), close during contraction (systole).

    • Semilunar Valves (SL): positioned between ventricles and arteries, open during contraction (systole) for blood ejection.

Vascular System Overview

  • Function and Dynamics:

    • A network of vessels providing oxygen and removing waste.

    • Arteries (including arterioles): strong vessels that expand and contract with heart pressure.

    • Veins (including venules): accommodate larger blood volumes; operate under low pressure with skeletal muscle contractions aiding flow.

    • Capillaries: smallest vessels linking arterial and venous systems.

Cardiac Cycle

  • Phases of Cardiac Cycle:

    • Systole: ventricular contraction, AV valves close, SL valves open, blood ejected.

    • Diastole: ventricles relax, filling with blood, AV valves open.

    • Assess heart sounds during these phases, identify S1 (closure of AV valves) and S2 (closure of SL valves).

Electrical Conduction of the Heart

  • Conduction System:

    • SA node: initiates impulses (60-100 bpm), controls heart contraction rates.

    • AV node: receives impulses, stimulates ventricular contraction (40-60 bpm).

Client Assessment Preparations

  • Client Interaction:

    • Maintain modesty and explain procedures before starting assessment.

    • Inspect neck for jugular veins and carotid arteries with client supine at a 30-45 degree angle for better visualization.

Inspection and Palpation Steps

  • Inspection of Neck:

    • Assess jugular veins for pulsation without distension.

    • Observe carotid arteries for visible pulsations indicating normal blood flow.

  • Expected Findings:

    • Jugular veins should not bulge; carotid pulses should be visible and strong.

  • Palpate Carotid Arteries:

    • Use gentle pressure for pulse strength and compare bilaterally.

  • Compare Strength:

    • Moderate, equal strength expected.

Additional Inspection Techniques

  • Assessment of Chest Movement:

    • Observe symmetry and apricots of chest movements; visualize PMI location at fifth intercostal space.

    • Note any lifts or heaves as potential indicators of underlying issues.

Subjective Data Collection

  • Chest Pain Questions:

    • Explain location, quality (sharp, dull), duration, and factors affecting pain.

    • Collect related symptoms for context.

Objective Data and Interventions

  • Monitor Vital Signs:

    • Oxygenation status via skin color and respiratory effort metrics.

    • Watch for peripheral edema and jugular vein distension.

  • Intervention Protocols:

    • Positioning, oxygen supply, and constant ECG monitoring as necessary.

Auscultation Techniques

  • Client Positioning:

    • Supine with head elevated 30 degrees; begin auscultation methodically following a Z pattern across the precordium for heart sounds.

Expected Heart Sounds

  • S1 and S2 Characteristics:

    • Expected findings: low and high-pitched sounds indicative of normal valve function, noting any irregularities or extra sounds.

Extremity Assessment

  • Inspection:

    • Examine skin tone, temperature, symmetry, and hair distribution on extremities.

    • Evaluate fingernails for color and shape.

  • Palpation:

    • Check for temperature, moisture, and pulse strength, noting baseline pulses for abnormalities.

Nursing Actions for Edema and Ulcers

  • Evaluate and Measure:

    • Document edema and ulcer specifics, notifying providers of significant findings.

    • Encourage movement and weight management strategies to support cardiac health.

Lifestyle Interventions for Cardiac Health

  • Health Education:

    • Yearly screenings for blood pressure, glucose, cholesterol; dietary modifications to lower LDL levels.

    • Exercise Recommendations:

      • 150-300 minutes of moderate exercise weekly, with muscle strengthening activities.

    • Stress Management Strategies:

      • Promote relaxation techniques for overall well-being.

    • Dietary Recommendations:

      • Emphasize a balanced Mediterranean diet; limit saturated fats, sugars, sodium intake.

    • Tobacco Cessation:

      • Encourage quitting smoking for long-term cardiovascular health benefits.
