Study Notes
Heat-Related Illnesses
- Untreated heat exposure can lead to heat stroke, characterized by flu-like symptoms such as weakness, nausea, vomiting, and intense headaches, with normal body temperature and hyponatremia.
Heat Stroke
- Heat stroke is a medical emergency requiring immediate treatment to prevent death, with body temperatures possibly exceeding 104°F.
- Two types:
- Exertional: Rapid onset due to strenuous activity in hot, humid conditions.
- Classical: Develops over time from prolonged exposure to high temperatures.
Assessment of Heat Stroke
- History of heat exposure and elevated temperature above 104°F.
- Mental status changes including confusion and agitation can occur.
- Signs include hypotension, tachycardia, tachypnea, hot dry skin, oliguria, and electrolyte imbalances.
Anaphylaxis from Bee Stings
- Assess for skin reactions, swelling, urticaria, and lip/tongue edema.
- Anaphylaxis symptoms include bronchospasm, hypotension, and possible cardiac arrhythmias, along with systemic effects like nausea and renal failure.
- Vital signs monitoring is crucial; treatments include antihistamines, epinephrine, albuterol, and corticosteroids.
Snakebites
- Major risks include airway compromise and respiratory failure; immediate access to resuscitation equipment is necessary.
- Contact Poison Control for antivenin advice.
Lightning Injuries
- Generally preventable with effects ranging from confusion to respiratory failure.
- Moderate injuries may require vasoactive medications, oxygen, and fluid resuscitation.
Cardiogenic Shock
- Results from the heart's failure to pump blood effectively, which leads to inadequate oxygen supply.
- Symptoms include angina, arrhythmias, feelings of doom, and increased cardiac enzyme levels.
- Treatment focuses on enhancing myocardial oxygen delivery, managing fluid levels, and monitoring hemodynamic status.
Distributive Shock
- Characterized by pooling of intravascular volume; includes septic, neurogenic, and anaphylactic shocks.
Septic Shock
- Common type of distributive shock with high mortality rates, especially in older adults.
- Symptoms include hyperthermia and hypotension accompanied by decreased urine output.
Interventional Treatments for Myocardial Infarction (MI)
- Percutaneous coronary intervention restores blood flow by using a balloon and stent within 12 hours of presentation.
- Fibrinolytic therapy is indicated in STEMI within 30 minutes of arrival and up to 3 hours from symptom onset.
Surgical Interventions
- CABG uses conduits to bypass blocked coronary arteries, reducing myocardial ischemia.
Mechanical Complications of MI
- Ventricular septal rupture is critical in the first 24 hours; it manifests as a new loud systolic murmur, necessitating urgent medical attention.
- Left ventricular free wall rupture and mitral regurgitation present similar risks for rapid deterioration.
- Pericardial complications may manifest weeks after MI, characterized by pain exacerbated by breathing or swallowing.
Other Complications of MI
- Risks include thromboembolic events, dysrhythmias, acute kidney injury, and hyperglycemia.
Cardiac Rehabilitation
- Aims to integrate exercise, education, and counseling to improve heart health and reduce risk factors.
Acute Coronary Syndrome Nursing Interventions
- Initiate rest and monitor vital signs; administer medications and oxygen as needed.
Patient Education
- Emphasize a low-fat, high-fiber diet and the importance of carrying NTG.
- Regular follow-up with healthcare providers is critical.
Invasive Coronary Artery Procedures
- Procedures include PTCA, stenting, and CABG, with post-operative medication regimens commonly including aspirin and beta-blockers.
Saphenous Vein Grafts
- Used for bypass; however, they have a 50% occlusion rate after ten years.
Internal Mammary Artery Grafts
- Considered superior to saphenous grafts; have a patency rate of 90% at ten years.
Management of Dysrhythmias
- Disturbances in heart rhythms can lead to complications; types encompass atrial and ventricular disorders.
Assessment of Dysrhythmias
- Includes monitoring skin color, pulse characteristics, and blood pressure to identify potential complications like cardiac arrest and thromboembolic events.
Ongoing Nursing Interventions
- Focus on managing dysrhythmias, reassuring patients, and providing education on self-care and monitoring for ongoing symptoms.
