Total questions: 15
Worksheet time: 15mins
What is the recommended duration for a spontaneous breathing trial (SBT) to assess readiness for extubation?
10 minutes
30 minutes
1 hour
2 hours
Which of the following parameters is often assessed during a spontaneous breathing trial?
Heart rate
Blood pressure
Arterial blood gases (ABG)
All of the above
Which of the following is a common indication for performing a spontaneous breathing trial?
Patient is fully awake
Patient has a stable respiratory rate
Patient is on minimal sedation
All of the above
What is the primary goal of a spontaneous breathing trial (SBT)?
To assess the need for mechanical ventilation
To evaluate the patient's ability to breathe independently
To monitor the patient's heart function
To determine the effectiveness of sedation
During a spontaneous breathing trial, which of the following signs may indicate failure?
Increased respiratory effort
Decreased oxygen saturation
Altered mental status
All of the above
What is the most common reason for a patient to fail a spontaneous breathing trial?
Anxiety
Respiratory muscle fatigue
Excessive secretions
All of the above
Which of the following is NOT a contraindication for performing a spontaneous breathing trial?
Severe respiratory acidosis
Unstable cardiovascular status
Patient is alert and cooperative
High levels of sedation
What is the typical monitoring frequency for vital signs during a spontaneous breathing trial?
Every 5 minutes
Every 15 minutes
Every 30 minutes
Continuous monitoring
A patient is being evaluated for extubation. Which of the following findings would indicate that the patient is NOT ready for extubation?
Spontaneous tidal volume of 5 mL/kg
Adequate cough reflex
FiO2 requirement < 0.4
Rapid shallow breathing index (RSBI) < 105
A patient has successfully passed a spontaneous breathing trial. What is the next step in the extubation process?
Extubate immediately
Perform a risk assessment for extubation
Increase sedation
Increase ventilator support
Which of the following values indicates potential difficulty in weaning a patient from mechanical ventilation?
Spontaneous tidal volume of 6 mL/kg
Maximum inspiratory pressure (MIP) < -20 cm H2O
Vital capacity > 10 mL/kg
Arterial oxygen saturation (SaO2) > 92%
What is the significance of a patient's ability to effectively cough before extubation?
It indicates the presence of a cough reflex, which helps clear secretions.
It signifies the patient is comfortable and ready for extubation.
It ensures the patient will not experience anxiety post-extubation.
It confirms adequate sedation levels.
What is a key factor to consider when determining the duration of a spontaneous breathing trial?
Patient's age
Underlying lung disease
Duration of mechanical ventilation
All of the above
Which of the following is a potential complication during a spontaneous breathing trial?
Hypoxemia
Hypercapnia
Respiratory distress
All of the above
What is the purpose of assessing the Rapid Shallow Breathing Index (RSBI) during a spontaneous breathing trial?
To evaluate the patient's oxygenation status
To determine the patient's respiratory muscle strength
To predict the likelihood of successful extubation
To monitor the patient's heart rate
