Respiratory Therapist Interview Questions
Describe a time you had to intervene quickly with a mechanically ventilated patient whose condition was deteriorating. What steps did you take, and what was the outcome?
Sample Answer
During a night shift, a patient with ARDS on PRVC ventilation experienced a sudden drop in SpO2 from 94% to 88%, with increasing peak pressures. My immediate action was to assess the patient, confirming ETT placement and checking breath sounds. I quickly reviewed ventilator alarms and settings, suspecting atelectasis. After in-line suctioning yielded thick secretions, I reassessed the patient; SpO2 improved to 92%, and pressures normalized. I immediately notified the physician and thoroughly documented the event in Epic, recommending a chest X-ray to confirm lung re-expansion, which showed improvement.
Tip: Use the STAR method to describe a specific critical event, highlighting your assessment, intervention, collaboration, and the positive outcome.
Explain the physiological differences between volume-controlled and pressure-controlled ventilation. When might you choose one over the other?
Sample Answer
Volume-controlled ventilation delivers a set tidal volume, allowing pressure to vary, which is suitable for stable patients needing precise minute ventilation. Pressure-controlled ventilation delivers a set inspiratory pressure for a set time, with variable tidal volume, often preferred for patients requiring lung protective strategies like ARDS, as it provides better control over airway pressures, reducing barotrauma risk. I'd use volume control for a patient post-surgery needing predictable ventilation, but pressure control for an ARDS patient to limit plateau pressures, targeting PEEP and driving pressure to prevent ventilator-induced lung injury.
Tip: Demonstrate a deep understanding of the physiological implications and practical applications of each mode, not just definitions.
Tell me about a challenging patient education scenario where you had to explain complex respiratory care (e.g., home oxygen, inhaler technique) to a patient or family with limited health literacy. How did you approach it?
Sample Answer
I once had a geriatric patient with newly diagnosed COPD and limited English proficiency struggling with their inhaler regimen. Recognizing verbal instructions weren't enough, I used a 'teach-back' method with a demo inhaler, showing each step and asking them to demonstrate. I also utilized a visual aid booklet translated into their native language and engaged their family member. Over several sessions, the patient's demonstrated correct technique improved from 20% to 90%, significantly reducing their risk of readmission due to poor medication adherence.
Tip: Show empathy and adaptability. Emphasize using multiple teaching methods and demonstrating a positive patient outcome or improvement in understanding.
You receive an ABG result of pH 7.28, PaCO2 55 mmHg, PaO2 60 mmHg, HCO3 24 mEq/L. How do you interpret this, and what immediate actions would you consider?
Sample Answer
This ABG indicates uncompensated respiratory acidosis with hypoxemia. The low pH and high PaCO2 suggest acute respiratory failure. My immediate actions would involve assessing the patient's respiratory effort and mental status. I'd initiate or increase oxygen therapy and likely consider non-invasive positive pressure ventilation (NIPPV) if they're conscious and cooperative, or prepare for intubation if their respiratory drive is severely depressed or they're rapidly fatiguing. I would also notify the physician immediately with these critical findings.
Tip: Clearly identify the acid-base disorder, link it to the clinical picture, and outline a logical sequence of interventions based on severity.
Describe your role and responsibilities during a Code Blue or rapid response situation. Can you provide an example?
Sample Answer
During a Code Blue, my primary role is airway management. I immediately secure appropriate equipment, including BVM, intubation supplies, and suction. I assist with intubation by preparing the ETT, assessing breath sounds post-intubation, and securing the tube. I also manage ventilation with the BVM until the patient is on a ventilator, ensuring proper oxygenation and ventilation, titrating oxygen to maintain SpO2 >90%. For instance, in a recent code, I secured the ETT in under 30 seconds and ensured continuous ventilation while the physician focused on circulation, contributing to a successful resuscitation and return of spontaneous circulation (ROSC).
Tip: Detail your specific responsibilities and expertise in airway management during high-stress, time-sensitive events.
Describe a time you disagreed with a physician or another healthcare team member regarding a patient's respiratory care plan. How did you handle it professionally, and what was the resolution?
Sample Answer
I once had a situation where a physician wanted to maintain a high FiO2 for a COPD patient, while I observed rising PaCO2 levels, suggesting oxygen-induced hypercapnia. I respectfully approached the physician, presenting the latest ABG results (pH 7.32, PaCO2 62 mmHg) and explained the physiological rationale for carefully titrating oxygen in COPD exacerbations, referencing evidence-based guidelines. We collaboratively decided to slowly wean the FiO2 while closely monitoring SpO2 and repeat ABGs. The patient's PaCO2 subsequently improved to 55 mmHg, and their mental status cleared, reinforcing shared decision-making.
Tip: Focus on professionalism, evidence-based arguments, patient advocacy, and a collaborative resolution, using data to support your point.
You're assessing a new admission with a severe COPD exacerbation. What key assessment findings would you prioritize, and what initial interventions would you anticipate ordering or performing?
Sample Answer
For a severe COPD exacerbation, I'd prioritize assessing the patient's work of breathing, accessory muscle use, and mental status, as these indicate respiratory fatigue. I'd auscultate for diminished breath sounds or wheezing, check SpO2 via pulse oximetry, and assess for central cyanosis. Initial interventions would include administering short-acting bronchodilators (e.g., albuterol/ipratropium nebulizer), titrating oxygen to maintain an SpO2 of 88-92% to prevent hypercapnia, and considering non-invasive positive pressure ventilation (NIPPV) if signs of acute respiratory acidosis or severe dyspnea are present, preparing for intubation if NIPPV fails.
Tip: Outline a systematic approach to assessment and immediate, evidence-based interventions for a critical respiratory condition.
Discuss different airway clearance techniques (ACTs). When would you recommend specific ACTs, and what factors influence your choice?
Sample Answer
Airway clearance techniques (ACTs) are vital for patients with excessive secretions. I consider postural drainage and percussion for localized issues, often with cystic fibrosis patients, while mechanical devices like a high-frequency chest wall oscillation vest (e.g., The Vest) are effective for generalized mucus plugging in conditions like bronchiectasis. For cooperative patients, positive expiratory pressure (PEP) devices like an Acapella or flutter valve are excellent. The choice depends on the patient's condition, mobility, cognitive status, and specific diagnosis. For instance, I recently taught a patient with severe asthma to use an Aerobika OPEP device, improving their FEV1 by 15% after consistent use.
Tip: Describe various techniques, their indications, and factors influencing your choice, demonstrating an understanding of individualized care.
Describe your approach to thorough and timely documentation in the EHR. Why is it so critical for respiratory care?
Sample Answer
My approach to EHR documentation (e.g., in Cerner) is to be thorough, timely, and concise, adhering to charting-by-exception where appropriate, but always capturing significant changes. It’s critical for continuity of care, ensuring every team member has up-to-date information on patient status, interventions, and responses. Accurate documentation supports billing, prevents medical errors, and provides a legal record. For instance, after administering a bronchodilator, I immediately chart the medication, dosage, patient's pre and post-treatment assessment (breath sounds, SpO2, subjective improvement), and any adverse reactions, ensuring proper handoff and compliance.
Tip: Emphasize the importance of documentation for patient safety, communication, and legal compliance, mentioning specific types of information you record.
Healthcare environments can be unpredictable. How do you manage competing priorities and adapt your care plan when unexpected situations arise during your shift?
Sample Answer
Healthcare is inherently dynamic, requiring constant prioritization. I start each shift by reviewing my patient assignments and their immediate needs. If an unexpected critical event, like a rapid response or a suddenly decompensating patient, occurs, I quickly assess its urgency. I delegate less time-sensitive tasks if possible, communicate changes to relevant nursing staff, and focus on the emergent situation. For example, during a shift, I had planned medication rounds, but a patient developed acute respiratory distress. I immediately redirected to stabilize that patient, coordinating with the nurse, then adjusted my subsequent rounds to ensure all patients still received timely care.
Tip: Showcase your ability to manage stress, prioritize effectively, communicate clearly, and adapt your plan in a fast-paced clinical setting.
