Description:

What is the Lab Name for Brain Natriuretic Peptide (BNP) Lab Values?

Brain Type Natriuretic Peptide

What is the Lab Abbreviation for Brain Type Natriuretic Peptide?

BNP

What is Brain Type Natriuretic Peptide in terms of Nursing Labs?

Brain natriureticpeptide (BNP) is a hormone made by the heart. When the heart is stressed or working hard to pump blood, it releases BNP.

What is the Normal Range for Brain Type Natriuretic Peptide?

<100 pg/mL

What are the Indications for Brain Type Natriuretic Peptide?

  • Identify:
    • Congestive Heart Failure (CHF)
    • Effectiveness of Treatment
    • Severity of Disease

What would cause Increased Levels of Brain Type Natriuretic Peptide?

  • Congestive Heart Failure (CHF)
  • Kidney Failure

What would cause Decreased Levels of Brain Type Natriuretic Peptide?

N/A

Overview

  1. BNP
    1. Normal Value Range
    2. Pathophysiology
    3. Special considerations
    4. Lab value elevations

Nursing Points

General

  1. Normal value range
    1. 100 pg/mL
  2. Pathophysiology
    1. Increased pressure overload due to increased SVR or volume
    2. Ventricular stretching causes release of BNP into bloodstream
    3. BNP released to aid in stress due to overload by:
      1. Increases excretion of sodium in urine = natriuresis
        1. Sodium follows water
      2. Decreased intravascular volume
      3. Decreased workload on the heart = improved cardiac function
  3. Special considerations
    1. Lavender tube (EDTA)
    2. NT-proBNP may be requested instead
      1. Submit in serum separator tube (tiger top)
  4. Elevated lab values
    1. >100 pg/mL – heart failure likely
    2. The higher the value, the more likely the diagnosis of heart failure

Assessment

  1. Assess patient for acute exacerbation of heart failure
    1. Lung sounds
    2. Oxygen status
      1. Need for supplemental oxygen
  2. Radiographic evaluation
  3. May need diagnostics for evaluation
    1. Echocardiogram can determine contractility function

Therapeutic Management

  1. Treatment
    1. Treat heart failure
      1. Diurese
      2. Improve contractility

Nursing Concepts

  1. Lab Values
  2. Perfusion
