Study Notes

Medication Information

  • Adrenaline (Epinephrine): Alpha-adrenergic agonist, used to start heartbeats, treat acute asthma attacks, hemostasis, bronchospasm, anaphylaxis, and allergic reactions; also used during cardiac arrest, adjustment for anesthesia, and shock treatment of bronchospasms, and anaphylactic reactions.
  • Atropine Sulphate: Anticholinergic and muscarinic antagonist. Used to treat bradycardia, and decreases/suppresses secretions during surgery.
  • Aminophylline (Theophylline): Bronchodilator that relaxes bronchial smooth muscles. Stimulates beta 2 receptors and alpha and beta receptors in the sympathetic nervous system.
  • Dexamethasone (Decadron): Anti-inflammatory/corticosteroid that decreases inflammation, stabilizes leukocytes, and suppresses immune response.
  • Digoxin (Lanoxin): Cardiac glycoside that corrects tachycardia and strengthens heart muscle. Inhibits the sodium pump to increase intracellular calcium and myocardial contractility. Inhibits conduction through AV nodes and increases heart rate.
  • Diazepam (Valium): Anti-convulsant, anxiolytic, and sedative. Potentiates the effects of GABA, depresses the CNS, and suppresses seizure activity.
  • Dobutamine (Dobutrex): Adrenergic agonist, vasopressor, treats cardiac decompensation; stimulates beta-1 receptors, increases contractility, and cardiac output.
  • Dopamine (Intropin): Alpha and beta adrenergic agonist. Corrects imbalances in shock syndrome. Increases cardiac output. Increases systolic and pulse pressure in shock.
  • Furosemide (Lasix): Loop diuretic that inhibits sodium and chloride reabsorption. Used to treat cardiac toxicity of hyperkalemia.
  • Hydrocortisone: Corticosteroid used for severe inflammation and adrenal insufficiency. Suppresses immune response and influences metabolism.
  • Isoproterenol (Isuprel): Beta-adrenergic agonist, bronchodilator, and cardiac stimulator. Treats shock. Relaxes vascular smooth muscles.
  • Lidocaine (Xylocaine): Anti-arrhythmic and local anesthetic. Used to treat arrhythmias (V-fib and V-tach).

Side Effects and Nursing Considerations

  • Adrenaline (Epinephrine): Sweating, headaches, anxiety, tachycardia, dry mouth, constipation. Observe patients closely for adverse reactions. Notify prescriber.
  • Atropine: Sweating, headaches, anxiety, dry mouth, constipation, dysphagia, tachycardia. Monitor for tachycardia, especially in cardiac patients; adverse reactions may vary.
  • Aminophylline: Nausea, vomiting, shock, drowsiness, headache.
  • Dexamethasone: Fluid & electrolyte disturbances, impaired wound healing, increased intracranial pressure. Monitor patient for depression in high-doses.
  • Digoxin: Nausea, vomiting, dizziness, blurred vision. Monitor pulse rate and withhold if pulse is less than 60 bpm.
  • Diazepam: Nausea, dry mouth, headaches, nervousness. Observe for dizziness, ataxia, and falls.
  • Dobutamine: Headache, fatigue, shortness of breath, tremors, nervousness. Monitor ECG, central venous pressure, pulse rate, and urine output.
  • Dopamine: Nausea, vomiting, pain, palpitations, headaches. Monitor ECG, blood pressure, cardiac output and urine output during infusion.
  • Furosemide: Nocturia, dizziness, nausea, diarrhea, cramping, anorexia. Monitor vital signs, fluid intake, and output.
  • Hydrocortisone: Depression, psychotic episodes, increased insulin needs. Monitor glucose levels.
  • Isoproterenol: Headaches; nausea and vomiting, hypertension, arrhythmias. Monitor ECG
  • Lidocaine: Headache, nausea. Monitor drug levels.

Other Information

  • Emergency Trolley: Contains essential medications for emergency situations, such as cardiac arrest and code-blue situations.
  • Crash Cart Types: Categorized by age (adult, pediatric, newborn intensive care).
  • Crash Cart Contents: Includes monitors/defibrillators, Advanced Cardiac Life Support drugs, first-line drugs (e.g. adenosine, dextrose, diazepam, or midazolam).
