exam 2 study guides Flashcards
List the anatomical structures of the respiratory system and identify the function
of each structure.
Conducting Zone
Nasal Cavity
Pharynx
Trachea
Bronchi
Most Bronchioles
Purpose is to provide a route for air, remove
debris, warm and humidify a
Bronchioles
Alveolar Ducts
Alveolar Sacs
Purpose is to perform gas exchang
What are the three types of inhalation drug devices?
nebulizers, pressurized metered-dose inhaler (pMDI), and dry powder inhalers (DPIs)
List the patient education needed for using inhalers.
Prime inhaler prior to INITIAL use
2) Activate the canister at the beginning of a slow deep breath
3) Press down on the inhaler quickly to release the
medicine as you start to breathe in slowly for 3 to 5
seconds
4) Then hold your breath for 10 seconds to allow medicine to go deeply into your lungs
5) Breathe out slowly
6) Wait 2 minutes between inhalation
What are some of the common causes of asthma?
inflammation, edema, and bronchospasm of the airways, which inhibits air from entering the lungs.
- Excessive mucus secretion can occur, contributing to airway blockage.
- Immune system cells can infiltrate the walls of the bronchi and bronchiole
What are the differences between asthma and COPD?
COPD-Chronic inflammatory lung disease that causes obstructed airflow out of the lungs
asthma is diifucitly breathing
COPD is more serious and is a lot harder ti breath in
asthma prevents it from coming in,copd prevents it from going out
What is the difference between a preventer and reliever? Describe how each
would be used.
Preventers – that slowly make the airways less sensitive to triggers by reducing swelling and mucus inside the airways. This medication is taken daily.
Relievers – that act quickly to relax the tight muscles around the airways and are used when symptoms breakthrough, despite good asthma management.
What is the difference between first- and second-generation antihistamines?
First-generation antihistamines block both histaminic and muscarinic receptors as well as passing the blood-brain barrier.
Second-generation antihistamines mainly block histaminic receptors and do not pass the blood-brain barrier.
Why are drugs for asthma and COPD given by inhalation?
the medicine quickly reaches the airways and less is absorbed into the bloodstream.
Allergic Rhinitis
What is it
Causes/ Triggers
Assessment findings
Interventions-
Pharmacological & Non-
pharm
Patient Teaching
What is it –Immune reaction to foreign substance. Creates antibodies, causing inflammatory response
Causes/ Triggers-hay fever, food allergy, insect bite, drug allergy, aczcems
Antihistamines
* Diphenhydramine
* Cetirizine
Corticosteroid
* Fluticasone
* Prednisone
* Severe
Asthma
What is it
Causes/ Triggers
Assessment findings
Interventions-
Pharmacological & Non-
pharm
Patient Teaching
What is it
Inflammation, edema, and bronchospasm of the airways, which inhibits air from entering
the lungs.
- Excessive mucus secretion can occur, contributing to airway blockage.
- Immune system cells can infiltrate the walls of the bronchi and bronchioles
triggers
Dust
* Pollen
* Pet hair or dander
* Changes in the weather
* Mold
* Tobacco smoke
* Respiratory infections
* Exercise
* Stress
treatment-albuterol
COPD
What is it
Causes/ Triggers
Assessment findings
Interventions-
Pharmacological & Non-
pharm
Patient Teaching
hronic inflammatory lung disease that causes obstructed airflow out of the lungs
Two types: Emphysema and Chronic Bronchitis
Chronic – treatable but not curable
Triggers:
Irritating gases or dust
Smoking
Symptoms:
Shortness of breath
Chest tightness
Cough
Mucus (sputum) production (clear, white, yellow or green)
Cyanosis
Frequency respiratory infections
Lack of energy
Unintended weight loss (later stages)
Wheezing
Treatment:
Expectorant (guaifenesin)
Anticholinergic (tiotropium)
Corticosteroids (prednisone)
Xanthine derivative (theophylline)
Common cold
What is it
Causes/ Triggers
Assessment findings
Interventions-
Pharmacological & Non-
pharm
Patient Teaching
iral infection of the upper respiratory tract
Symptoms appear 1 – 3 days after exposure
Children <6 are at greatest risk
Recover in a week or 10 days
Symptoms:
Runny or stuffy nose
Sore throat
Cough
Congestion
Slight body aches or a mild headache
Sneezing
Low-grade fever
Generally feeling unwell (malaise)
Treatment:
Expectorant (guaifenesin)
Decongestant (pseudoephedrine)
Antitussives (dextromethorphan)
albuterol
MOA
Patient teaching
side effects
Mechanism of Action:
- Stimulate beta-2 adrenergic receptors of bronchi
and bronchioles producing bronchodilation. Beta-1
receptors can inadvertently cause tachycardia.
Adverse/Side Effects:
- Muscle tremors
- Excessive cardiac stimulation
- CNS stimulation
Patient Teaching/Education:
- SABA is for use in acute asthma attack
- LABA is NOT for acute asthma attack
- Take as directed
- Prime inhaler prior to first use
- Rinse mouth d/t unusual taste
theophylline
MOA
Patient teaching
side effects
Mechanism of Action:
- Relaxes bronchial smooth muscle by inhibition of the
enzyme phosphodiesterase and suppresses airway
responsiveness to stimuli that cause bronchoconstriction.
Adverse/Side Effects:
- Nausea / vomiting
- CNS stimulation
- Nervousness
- Insomnia
Patient Teaching / Education:
- Avoid caffeine
- Requires evaluation of therapeutic blood levels to
prevent toxicity
- Drink fluids to thin secretions, avoid irritant
guaifenesin
MOA
Patient teaching
side effects
Mechanism of Action:
- Reduces viscosity of thick secretions by irritating the gastric vagal receptors that stimulate the respiratory tract fluids (thin secretions)
Nursing Considerations:
- Safe for all ages
- Only recommended in pregnancy when benefit outweighs risk
Adverse/Side Effects:
- Skin rash
- Headache
- Nausea
- Vomiting
Patient Teaching/Education:
- Increase hydration (thins secretions)
- Avoid irritants that stimulate coughing
- Can cause drowsiness
- Avoid alcohol and other CNS depressan
