Questions and Answers

A patient preparing for the CCRN exam asks for advice on how to approach questions. Which strategy is most effective?

  • Only consider information that is typical for patients.
  • Focus on absolute words like 'always' and 'never'.
  • Always choose the shortest answer to save time.
  • Select the answer that includes the most embedded answers. (correct)

According to the provided resources, what is the suggested approach to answering questions that contain negative words?

  • Select options that closely resemble typical patient scenarios.
  • Answer quickly, as they are usually straightforward.
  • Pay close attention and read the questions deliberately. (correct)
  • Choose the option that contains absolute words.

How does heart rate (HR) dependency for cardiac output (CO) vary between neonates/children and adults?

  • Neither group is significantly HR dependent.
  • Adults are more HR dependent than neonates because of higher SV.
  • Neonates/children are more HR dependent due to their inability to increase SV effectively. (correct)
  • Both groups are equally HR dependent.

  • Testable Nursing Actions: Applying leads for CV monitoring, identifying and monitoring rhythms, assessing hemodynamic status, and managing patients requiring various interventions like ECGs, arterial catheters, cardiac caths, cardioversion, CVP monitoring, defibrillation, invasive hemodynamic monitoring, and vascular stenting.

Cardiovascular Anatomy and Physiology Overview

  • A strong grasp of normal anatomy is crucial for recognizing abnormalities.
  • Cardiac Output (CO) is the volume of blood ejected from the LV in 1 minute.
  • CO = Heart rate x Stroke volume.
  • Factors Influencing CO: Preload, afterload, compliance, and contractility.
  • Cardiac Index (CI) = Cardiac output / BSA.
  • Stroke Volume (SV) is the volume of blood ejected from the LV with each contraction.
  • SV influencers: Preload, contractility, compliance, afterload.

Preload Explained

  • Preload is the volume of blood in the ventricles at the end of diastole and before contraction.
  • It is determined by cardiac fiber length/strength and the volume of blood returned to circulation.
  • Measurement: RA line and CVP estimate preload; PA artery capillary wedge pressure is an exact measurement.
  • Frank-Starling Law: The force of contraction is proportional to initial muscle fiber length.
  • Myocardial Failure: Volume can worsen a patient’s clinical status.
  • Factors Affecting Preload: Variations in volume, systemic/pulmonary HTN, excessive PEEP, dysrhythmias, vasopressors/inotropes.
  • Interventions to Increase Preload: Volume administration (crystalloids, colloids, blood products), compensatory mechanisms (renin-angiotensin, ADH, aldosterone, catecholamines).
  • Interventions to Decrease Preload: Diuretics, ANP/BNP, vasodilators, afterload reduction (milrinone).

Afterload Explained

  • Afterload is the workload ventricles must overcome to pump; systemic BP estimates afterload.
  • Measured by SVR and PVR.
  • SVR = (MAP – CVP) / CO.
  • High afterload can decrease CO in a sick heart.
  • Increase Afterload: Systemic/pulmonary HTN, polycythemia, outflow obstructions, vasoconstrictors, heart failure.
  • Decrease Afterload: Sepsis, vasodilators (cardene, nipride), anaphylaxis.

Compliance Explained

  • Compliance is the ability of ventricles to relax and distend during diastole.
  • Compliance = change in V / change in P.
  • "Good” compliance means a large volume of fluid creates only a small change in ventricular pressure.
  • “Poor” compliance means a small fluid volume can produce a large pressure change.
  • Decreased Compliance: Myocardial hypoxemia/acidosis, CHF, ventricular hypertrophy, pericardial tamponade, high PEEP, positive inotropic medications.
  • Enhanced Compliance: Afterload reducers - milrinone!

Contractility Explained

  • Contractility is the squeeze generated by the myocardial muscle.
  • Measurement: Echocardiography estimates contractility; cardiac cath directly measures it.
  • Atrial contraction accounts for 10-40% of LV filling, depending on HR (atrial kick).
  • Shortening and Ejection Fraction are measures.
  • Factors Affecting Contractility: Electrolyte imbalances (Ca), sympathetic stimulation, physiological depressants, pharmacological agents.
  • Increase Contractility: Positive inotropes, sympathetic stimulators, hypercalcemia.
  • Decrease Contractility: Pharmacology, negative inotropes, hypoxemia/hypercapnia, long-term CHF, parasympathetic stimulators, acidosis, hypo/hypercalcemia, hypo/hyperglycemia/magnesemia/natremia/kalemia.

Autonomic Nervous System Explained

  • Sympathetic Stimulation: Releases norepinephrine (NE), increases HR, contractility, and conduction time.
  • Parasympathetic Stimulation: Releases acetylcholine, decreases HR and conduction time via vagus nerve stimulation.
  • Alpha (α) Adrenergic (norepi, phenylephrine, dopamine at higher doses): Arterial vasoconstriction, increases intracellular calcium.
  • Beta (β) Adrenergic: Increases SA node discharge, increasing inotropy, chronotropy, and AV conduction time.
  • B1 (epi, dopamine at lower doses): Acts on heart, agonists increase inotropy, chronotropy, and rennin secretion.
  • B2 (dobutamine): Acts on lungs, agonists prompt smooth muscle relaxation, bronchodilation.
  • Vasopressors: Typically raise BP.
  • Inotropic: Act through alpha and beta receptors to vasodilate/vasoconstrict/enhance contractility.
  • Chronotropic: Change HR by affecting nerves controlling the heart or rhythm from the SA node.

Disorders of the Heart: Cardiac Failure

  • Cardiac Failure: Heart's inability to maintain sufficient cardiac output to meet the body’s needs.
  • Left Heart Failure: LV unable to completely empty during systole.
  • Pathophysiology: Decreased CO from decreased contractility, backflow of blood from LV to LA, increased PAP, PCWP, and CVP.
  • Causes: LV infarction, valvular disease (pediatrics).
  • Clinical Manifestations: Respiratory (pulmonary venous congestion/edema, dyspnea, tachypnea, rales, frothy sputum, decreased SaO2/PaO2), Cardiac (cardiomegaly, poor perfusion, tachycardia, hypotension, S3 sound).
  • Late Signs: Right Heart Failure, acidosis, decreased GFR, decreased mentation.

Right Heart Failure Explained

  • Right Heart Failure: Often a progression of left heart failure.
  • Causes: Pulmonary HTN, RV infarct, cardiomyopathy.
  • Pathophysiology: Increased myocardial oxygen demand/HR/PA pressures, decreased CO, pulmonary vasculature resistance.
  • Clinical Manifestations: JVD, hepatojugular reflux, dependent pitting edema, hepatomegaly, anorexia, nausea, failure to thrive, weight gain, increased CVP/PVR.
  • Diagnosis of Congestive Heart Failure: History, PE, labs, CXR.
  • Split heart sounds/murmurs.
  • Decreased peripheral pulses
  • Increased liver size.
  • ECG/ECHO changes.
  • Lab Findings: Dilutional anemia/hyponatremia, decreased UOP, albumin in urine, hypoglycemia, increased WBCs, polycythemia, iron deficiency anemia.

Treatment of Congestive Heart Failure

  • Goals: Maximize cardiac performance and reduce myocardial oxygen demand.
  • Inotropic Agents: Digoxin, milrinone, VADs--promote increased contractility to increase CO.
  • Decrease Myocardial Oxygen Demand: Dobutamine, bedrest, anxiolytics, beta blockers, dysrhythmia/pain management
  • Optimize (Reduce) Preload: Diuretics, restrict sodium/fluids, venous dilation with nitroglycerin.
  • Decrease Afterload: Nipride (nitroprusside), ACE inhibitors (captopril), milrinone, IABP in extreme cases.

Cardiomyopathies Explained

  • Cardiomyopathies: Disease of the heart muscle.
  • Types: Dilated, hypertrophic, restrictive.
  • Dilated (“the big”): Most common in children, massive cardiomegaly/LV dilation, decreased SV/EF on echo.
  • Management: Positive inotropic agents, diuretics, vasodilators, afterload reduction (milrinone).
  • Hypertrophic (“the bad”): Increased myocardial mass, decreased ventricular cavity size, blood flow obstruction (LVOTO).
  • Management: Beta adrenergic agonists, calcium channel blockers, diuretics/inotropes with caution, pacing, surgical resection.
  • Restrictive (“the ugly”): Defect of the endocardium itself due to fibrosis/scarring, normal systolic function but decreased diastolic function.
  • Management: None specific, CHF, symptomatic treatment (diuretics, digoxin, vasodilators, antiarrhythmics), lifestyle changes.
  • Clinical Manifestations of Cardiomyopathy: Cardiomegaly, poor perfusion, CHF, low CO, decreased UOP/LOC, syncope, thromboembolic events, arrhythmias, shock.
  • Diagnosis: CXR, ECG, Echo, viral titers, cardiac cath.
  • General Management Principles: Decrease cardiac workload (fluid/sodium restriction, supplemental oxygen, intubation/ventilation), DVT prophylaxis, VADs, transplant.

Cardiogenic Shock Explained
