Module 7 Flashcards
What are the three main classifications of medications affecting the respiratory system?
Antitussives, Mucolytics, Expectorants
Antihistamine and Decongestants
Bronchodilators and Antiasthma Drugs
These classifications are essential for treating various respiratory conditions.
What is the primary action of antitussives?
Suppress the cough reflex
Antitussives are commonly used to relieve coughs.
Name one common drug classified as an antitussive.
Dextromethorphan
Dextromethorphan is widely used in over-the-counter cough medications.
What is the primary action of mucolytics?
Break down mucus
Mucolytics help make mucus less viscous and easier to expel.
Name one common drug classified as a mucolytic.
Acetylcysteine
Acetylcysteine is used to treat conditions with excessive mucus production.
What is the primary action of expectorants?
Facilitate mucus clearance
Expectorants help patients cough up mucus more effectively.
Name one common drug classified as an expectorant.
Guaifenesin
Guaifenesin is often found in cold and flu medications.
What is the primary action of antihistamines?
Block histamine receptors
Antihistamines are used to relieve allergy symptoms.
Name one common drug classified as an antihistamine.
Diphenhydramine
Diphenhydramine is commonly used for allergic reactions and as a sleep aid.
What is the primary action of decongestants?
Reduce nasal congestion
Decongestants work by constricting blood vessels in the nasal passages.
Name one common drug classified as a decongestant.
Pseudoephedrine
Pseudoephedrine is frequently used for nasal congestion relief.
What is the primary action of bronchodilators?
Relax bronchial muscles
Bronchodilators are essential for treating asthma and COPD.
Name one common drug classified as a bronchodilator.
Albuterol
Albuterol is a commonly used bronchodilator for asthma attacks.
What is the primary action of antiasthma drugs?
Prevent or control asthma symptoms
Antiasthma drugs include both bronchodilators and anti-inflammatory medications.
Name one common drug classified as an antiasthma drug.
Fluticasone
Fluticasone is an inhaled corticosteroid used in asthma management.
List some common contraindications for respiratory medications.
- Hypersensitivity
- Severe asthma exacerbations
- Certain cardiovascular conditions
Contraindications can vary by specific medication.
What are some common drug interactions with respiratory medications?
- MAO inhibitors
- Other CNS depressants
- Beta-blockers
Interactions can lead to increased side effects or reduced effectiveness.
What are common adverse effects of respiratory medications?
- Drowsiness
- Dry mouth
- Nausea
- Increased heart rate
Adverse effects can vary widely depending on the medication class.
What should be included in health teaching for patients using antitussives?
Avoid alcohol and other CNS depressants
Patients should be informed about potential drowsiness and the importance of monitoring symptoms.
What should be included in health teaching for patients using mucolytics?
Stay hydrated to help loosen mucus
Adequate hydration enhances the effectiveness of mucolytics.
What should be included in health teaching for patients using expectorants?
Take with plenty of fluids
Fluid intake helps improve the effectiveness of expectorants.
What should be included in health teaching for patients using antihistamines?
Be cautious of drowsiness and avoid driving
Antihistamines can cause sedation, affecting activities that require alertness.
What should be included in health teaching for patients using decongestants?
Monitor for increased heart rate and blood pressure
Decongestants can have cardiovascular effects.
What should be included in health teaching for patients using bronchodilators?
Use a spacer for inhalers if needed
Spacers can improve medication delivery to the lungs.
