NURS 251 Pharm - Exam 5 Questions and Correct Answers Guaranteed Success All three of these diseases have one primary similarity - Correct Ansthey all involve obstruction of airflow through the airways.
alveoli - Correct Ansmicroscopic sacs where oxygen diffuses across and exchanged for carbon dioxide when a person breathes in air
Anti-inflammatory - Correct Ans- Inhaled corticosteroids (ICS), Leukotriene Inhibitors
- "controller" drugs because they reduce and control the inflammatory response.
- When inflammatory response is under control, bronchodilator drugs can work more
effectively.
Anticholinergic mechanism of action - Correct Ansby blocking effects of acetylcholine these drugs can produce bronchodilation and reduce volume of respiratory secretions.
Asthma - Correct Ansgeneral term for recurrent and reversible shortness of breath resulting from the narrowing of the bronchi and bronchioles.
Asthma pathophysiology - Correct Ans-narrowing of the bronchioles can be caused by bronchospasm, inflammation, edema and the production of mucus.
-This ultimately obstructs airflow meaning that the carbon dioxide cannot t get out and the oxygen cannot get in.
Basic treatment approach for persistent asthma - Correct Ans-Metered dose inhalers - contain a pressurized canister that delivers a reliable, consistent amount of medication via an aerosolized mist.-Starting with a low dose ICS and increasing stepwise by either increasing the dose of the ICS and/or adding a LABA.-Once a patient is on a high dose ICS and LABA oral corticosteroids may also need to be used to get patient's symptoms under control.
Beta adrenergic agonists mechanism of action - Correct Ansrelax and dilate the airways by stimulating the beta2 adrenergic receptors within the lungs.
Bronchodilation - Correct Ansinclude medications that improve airflow by relaxing smooth muscle cells in bronchials, leading to dilation and increased airflow.
Chemical Mediators - Correct Ansare defined as a substance released from mast cells and white blood cells during inflammation and allergic reactions. As such, chemical mediators are responsible for most of the symptoms and complications associated with asthma and COPD.
