    Study Notes

    Short-Acting Beta2-Agonists

    • Used to relieve bronchospasm.
    • Classified as a rescue medication, meaning it is taken as needed.
    • Use should be limited to no more than twice per week.
    • If used more than twice per week, should be used with an inhaled glucocorticoid to prevent adverse effects.

    Long-Acting Beta2-Agonists

    • Used for maintenance therapy to reduce the frequency of asthma attacks.
    • Should be used with an inhaled glucocorticoid.

    Inhaled Glucocorticoids

    • Easy to administer and deliver medication directly to the lungs.
    • Mild systemic effects.
    • Effective for long-term use in treating and managing asthma.
    • Can be used in combination with other medications.

    First-Generation Antihistamines

    • May induce sedation.

    Second-Generation Antihistamines

    • Have low lipid solubility, meaning they do not easily cross the blood-brain barrier.
    • Do not cause sedation.

    Ezetimibe

    • Used in the management of hyperlipidemia.
    • Inhibits the absorption of cholesterol in the intestinal tract.
    • Can have adverse effects like myopathy, hepatitis, pancreatitis, and thrombocytopenia

    Glucocorticoids

    • Potential side effects include bone growth inhibition, weight gain, hypertension, restlessness, agitation, and irritability.
    • Used to treat a variety of conditions including inflammation and severe asthma.

    Nitroglycerin

    • Used to treat angina.
    • Relaxes and prevents spasms in the coronary arteries.
    • Decreases the oxygen demand of the heart.
    • Transdermal patches should be placed in a hairless area of the body and rotated every few days to avoid skin irritation.

    Furosemide

    • A high-ceiling loop diuretic commonly used for heart failure.
    • Depletes potassium, sodium, chloride, magnesium, and water.
    • It is crucial to consume foods high in potassium to prevent hypokalemia (low potassium levels).

    Diltiazem

    • Calcium channel blocker used to manage atrial fibrillation.
    • Contraindicated in clients with hypotension.
    • Blocks calcium channels in the heart and blood vessels, lowering blood pressure.

    Heparin

    • Anticoagulant medication typically administered via intravenous pump.

    Cromolyn Sodium

    • A mast cell inhibitor used for prophylactic treatment of asthma. - Should be rinsed out of the mouth after use to prevent oral candidiasis (yeast infection).

    Methylprednisolone

    • An oral corticosteroid effective in the long-term treatment and management of asthma.

    Omalizumab

    • A medication that reduces the number of IgE molecules on mast cells, helping to prevent the release of histamine and other inflammatory mediators.
    • Used in severe asthma cases where other treatments have been ineffective.

    Warfarin

    • A blood thinner used to prevent blood clots.
    • Clients should avoid aspirin and ibuprofen due to their antiplatelet effects, as this could increase the risk of bleeding.
    • The International Normalized Ratio (INR) is used to monitor the effectiveness of warfarin therapy, usually drawn at the start of therapy and then regularly for the first few weeks.
    • Vitamin K can decrease the anticoagulant effects of warfarin.

    Alteplase

    • Used to treat myocardial infarction (heart attack), dissolving blood clots that are blocking the coronary arteries.
    • Bleeding is a potential adverse effect.

    Epinephrine

    • The first-line treatment for anaphylaxis.
    • Common adverse effects include hypertension, tachycardia (rapid heart rate), and dysrhythmias (irregular heartbeats).

    Tiotropium

    • Long-acting inhaled medication used to treat chronic obstructive pulmonary disease (COPD).
    • A common adverse effect is dry mouth.

    Clopidogrel

    • An antiplatelet medication that inhibits platelet aggregation.
    • It is important to monitor clients for recent myocardial infarction history.

    Aspirin

    • Suppresses platelet aggregation, making it a critical medication for preventing blood clots.
    • Used for immediate antithrombotic effect.

    Albuterol

    • Short-acting beta-2 adrenergic agonist used to manage acute asthma attacks.

    Fludrocortisone

    • Maintains electrolyte and fluid balance in clients with Addison's disease.

    Sodium Phosphate

    • Can cause electrolyte imbalance due to excessive fluid loss.

    Digoxin

    • Used to treat heart failure.
    • Contraindicated in clients with a heart rate less than 60 bpm.
    • May cause nausea, vomiting, fatigue, and visual disturbances in some clients.
    • Monitor heart rate and potassium levels during digoxin therapy.
