Patient Management OF HF

Overview of BNP and Heart Failure

  • BNP (B-type or Brain Natriuretic Peptides)

    • Definition: BNP is a biomarker used to assess heart failure.

    • Clinical significance: Indicates heart strain and ventricular stress.

    • Levels:

      • Normal: less than 100

      • Mild heart failure: over 300

      • Moderate heart failure: over 600

      • Severe heart failure: 900 and more

    • Note: The ventricle secretes BNP when it is being stretched or strained under pressure.

Echocardiogram

  • Purpose:

    • Measures the size of the left ventricle

    • Assesses ejection fraction, which is the amount of blood ejected from the left ventricle per pump

  • Normal ejection fraction: 55% to 70%

  • Heart failure indication: ejection fraction less than 40%

    • Note: A significant NCLEX key term indicating heart failure.

Hemodynamic Monitoring

  • Techniques:

    • Use of Swan-Ganz catheter (Pulmonary Artery Catheter)

  • Measurement:

    • Central Venous Pressure (CVP)

    • Normal range: 2 to 8

    • Clinical concern: CVP over 8 indicates potential fluid overload

    • Example: If CVP is over 22, the patient is at risk of drowning in their own fluid

    • It is the pressure in the thoracic vena cava near the right atrium, reflecting the amount of blood returning to the heart (venous return) and the heart’s ability to pump it into the circulation

    • Implication: Administer diuretics to drain excess fluid

    • Furosemide:

      • Classification: Diuretic

      • Note: It helps 'dry out' the body, a favored term for NCLEX.

Goals and Treatments in Heart Failure

  • Primary Goal:

    • Drain excess fluid from the body

  • Methods:

    • Medical treatment (medications)

    • Lifestyle changes

Lifestyle Changes: Using the Acronym "DOCTOR BEDS"

  • D: Diet

    • Low sodium and low fluid intake

    • Recommended: 2 liters (about 8 cups) of fluid per day and 2 grams of sodium or less daily

    • Foods to avoid:

      • Fried foods (e.g., fried chicken, French fries)

      • Canned foods and packaged products

      • Salty snacks (chips)

      • OTC medications (high sodium content)

    • Specific medications to avoid:

      • Cold and flu medications

      • Acetaminophen (Tylenol)

      • Antacids (e.g., Tums)

      • NSAIDs (e.g., aspirin, ibuprofen, naproxen)

    • Important note: Educate patients on sodium restriction as it contributes to swelling and worsened heart failure.

  • R: Risk for Falls/Orthostatic Hypotension

    • Recommendation: Advise patients to change positions slowly when standing or getting out of bed

    • Key term for NCLEX: Ensure patients understand the connection between position changes and fall risks.

  • B: Blood Pressure and BNP Levels

    • Importance: Monitor increases in blood pressure and BNP levels as they indicate worsening heart failure

    • Action: Notify healthcare provider if levels rise.

  • E: Elevation

    • Elevate head of the bed and use pillows for leg elevation to aid in breathing

    • Recommendation: Position patients in high Fowler's to facilitate easier breathing.

  • D: Daily Weights

    • Frequency: Patients should weigh themselves daily, not weekly

    • Clinical significance: Weight gain reflects fluid retention

    • Key numbers:

      • Over 2 to 3 pounds in one day or 5 pounds in one week necessitates notifying healthcare provider

    • Important NCLEX note: Be cautious of trick questions regarding weight metrics.

  • S: Sexual Activity

    • Guidelines: Sexual activity is safe for patients who can climb two flights of stairs without shortness of breath

    • Important term: Assess physical capacity before encouraging sexual activity.

  • Stockings (TED Hose)

    • Purpose: To decrease blood pooling

    • Important techniques:

      • Remove stockings daily and apply before getting out of bed

      • Never massage the calves of patients with CHF (Congestive Heart Failure)

Additional Notes for NCLEX Preparation

  • Common questions may cover the above critical points, ensuring comprehensive understanding for the exam.

  • Students should ensure familiarity with all mentioned concepts, measurements, and recommendations.
