PrepU Asthma Flashcards
Which drug is a selective, short-acting, inhaled beta2-adrenergic agonist (SABA) used as the initial rescue drug of choice for acute bronchospasm?
Albuterol
(subcutaneous epinephrine may be considered)
A client is prescribed salmeterol. The nurse would expect this drug to be administered by which route?
Inhalation
A client is prescribed a leukotriene receptor antagonist. The nurse should evaluate the effectiveness of the medication therapy based on long term management of symptoms associated with which respiratory condition?
A. Asthma
B. Chronic bronchitis
C. Pneumonia
D. Emphysema
A: They block or antagonize receptors for production of leukotrienes D4 and E4, blocking many of the signs and symptoms of asthma. This class of medicaton is not typically associated with the long term management of any of the other options.
3 long-acting beta-2 agonists (LABA)?
- formoterol
- salmeterol
- arformoterol
An asthmatic client on a beta blocker should be observed for which adverse reaction?
A. Pneumonia
B. Bronchospasm
C. Pleural effusion
D. Hypoglycemia
B. Can occur with beta blockade
As status asthmaticus worsens, the nurse would expect which acid-base imbalance?
Respiratory acidosis: the PaCO2 increases and pH decreases. (?)
Mr. Ashum is prescribed an albuterol inhaler as part of his treatment regimen for asthma. What is the mechanism of action for this medication?
A. Albuterol blocks stimulation of the beta-2 receptors
B. Albuterol causes relaxation of the bronchial smooth muscles
C. Albuterol reduces inflammation
B: This is the main result of albuterol binding to beta-2 receptors in the lungs. This action relieves bronchospasm, reduces airway resistance, facilitates mucous drainage, and increases vital capacity
During the summer, a female client experiences increased periods of acute symptoms of her asthma. The health care provider increases the dose frequency of which of her medications?
A. Salmeterol
B. Albuterol
B
A nurse caring for a client with asthma monitors respiratory function. Which level of asthma is seen by the following:
PEF 350 mL in AM, 200 mL at noon, symptoms occur continuously.
Severe persistent asthma: has frequent exacerbations and PEF is less than 60% of what is predicted with variability of 30%.
4 levels of asthma:
- mild intermittent
- mild persistent
- moderate persistent
- severe persistent
Which level of asthma is described as symptoms occurring more than 2 times per week (not daily). Exacerbations may affect activity with a PEF of (20%-30% variability?
Mild persistent asthma
Which level of asthma is characterized by symptoms occurring 2 or less times per week. Client is asymptomatic between attacks and has a normal peak expiratory flow (PEF).
Mild intermittent asthma
Which level of asthma has daily symptoms, exacerbations that affect activity, and PEF variability greater than 30%?
Moderate persistent asthma
An asthma educator is teaching a client newly diagnosed with asthma and the family about the use of a peak flow meter. The educator should teach the client that a peak flow meter measures highest airflow during which type of breath?
A. normal expiration
B. forced expiration
C. normal inspiration
D. forced inspiration
B
When treating status asthmaticus, which danger sign does the nurse observe for that would indicate respiratory failure?
Respiratory acidosis.
