- This page covers cardiac emergencies, emphasizing their critical nature, including acute myocardial infarction, unstable angina, and acute dysrhythmias. It explains that myocardial infarction and unstable angina stem from reduced blood flow due to coronary artery blockages, causing tissue ischemia and risk of cell death. Dysrhythmias result from issues in the heart's conduction system, affecting normal heart contractions.
- 22.1: Introduction to Cardiac Emergencies and Shock
- This page covers cardiac emergencies, highlighting acute myocardial infarction (AMI), unstable angina, and dysrhythmias, with a focus on symptoms, diagnostics, and treatments. It stresses the importance of cardiac output and coronary arteries.
- 22.2: Cardiac Emergency Drugs
- This page covers essential medications for cardiac emergencies, especially acute myocardial infarction (AMI) and unstable angina. It details the roles of aspirin, nitroglycerin, morphine, adenosine, atropine, diltiazem, epinephrine, procainamide, dopamine, and dobutamine, along with their indications, dosages, adverse effects, and contraindications.
- 22.3: Shock Drugs
- This page covers the treatment of various shock types with key drugs like epinephrine for anaphylactic shock, albuterol for bronchodilation, isotonic IV solutions for fluid restoration, and norepinephrine for improving cardiac output in cardiogenic shock. It details norepinephrine's action, dosing, adverse effects, and nursing considerations, such as vital sign monitoring and IV care. Client education emphasizes the importance of reporting changes in condition.
- 22.4: Chapter Summary
- This page covers cardiac emergencies and shock, detailing their causes like acute myocardial infarction and dysrhythmias that affect heart function and can be life-threatening. It also discusses treatments, including various medications such as nitrates, opioids, antiarrhythmics, adrenergic agonists, and intravenous fluids, focused on enhancing tissue perfusion in patients experiencing shock.
- 22.5: Key Terms
- This page provides an overview of cardiovascular conditions and treatments, highlighting terminology linked to heart function and emergencies. Key concepts include acute myocardial infarction, dysrhythmias, types of shock, and drug classifications like adrenergic agonists and calcium channel blockers. It also covers interventions such as defibrillation and essential measures like cardiac output and oxygen saturation.
- 22.6: Review Questions
- This page covers nursing assessments and interventions for clients with chest pain and cardiovascular issues, including respiratory monitoring, medication effects, and patient history. It addresses diagnoses like stable angina, correct dosages for medications, therapeutic expectations with epinephrine, and monitoring side effects from dopamine. The page also highlights preferred routes for administering emergency medications.
