What is the primary characteristic that distinguishes status asthmaticus from a typical asthma exacerbation?
What is the primary characteristic that distinguishes status asthmaticus from a typical asthma exacerbation?
- A rapid response to standard bronchodilator medications.
- The presence of a productive cough.
- The absence of wheezing during auscultation.
- Its resistance to typical treatment methods, posing a risk of respiratory failure. (correct)
Why does trapped air during status asthmaticus lead to respiratory failure?
Why does trapped air during status asthmaticus lead to respiratory failure?
- It stimulates the central nervous system, suppressing respiratory drive.
- It directly damages the alveolar walls, reducing gas exchange efficiency.
- It increases the effectiveness of inhaled medications, causing an overdose.
- It causes exhaustion due to the increased effort required for breathing, eventually leading to respiratory failure. (correct)
Which of the following physiological responses is LEAST likely to be observed in a patient experiencing status asthmaticus?
Which of the following physiological responses is LEAST likely to be observed in a patient experiencing status asthmaticus?
- Enhanced responsiveness to bronchodilators. (correct)
- Significant airflow limitation.
- Elevated carbon dioxide levels in the blood.
- Increased airway inflammation.
A patient in status asthmaticus is at high risk for respiratory failure. Which of the following mechanisms contributes MOST directly to this risk?
A patient in status asthmaticus is at high risk for respiratory failure. Which of the following mechanisms contributes MOST directly to this risk?
During status asthmaticus, which factor poses the GREATEST immediate threat to a patient's respiratory function?
During status asthmaticus, which factor poses the GREATEST immediate threat to a patient's respiratory function?
Flashcards
Status Asthmaticus
Status Asthmaticus
A severe, unrelenting, life-threatening asthma attack that doesn't respond to normal treatment, potentially causing respiratory failure.
Study Notes
- Status asthmaticus is a severe, unrelenting, life-threatening asthma attack.
- It does not respond to usual treatment.
- It places the patient at risk for respiratory failure.
- Symptoms of an acute asthma attack are present.
- Trapped air leads to exhaustion.
- Respiratory failure is the ultimate result.
