Respiratory Therapist

Interview questions for Respiratory Therapist roles.

10 questions

Question 1

Difficulty: medium

Can you walk me through how you assess a patient who arrives with shortness of breath in the emergency department?

Sample answer

My first priority is to quickly determine how unstable the patient is and whether they need immediate support. I start with a rapid ABC assessment, check vital signs, pulse oximetry, work of breathing, mental status, and listen for key lung sounds like wheezing, crackles, or diminished airflow. I also ask focused questions about onset, triggers, history of asthma, COPD, heart failure, recent illness, and current medications or inhaler use. If the patient is in distress, I would help apply oxygen per protocol, position them for easier breathing, and prepare for interventions such as nebulized bronchodilators, suctioning, or escalation to noninvasive ventilation if indicated. I’m careful to reassess after each intervention because respiratory status can change quickly. I also communicate clearly with the physician and nursing team so the patient gets the right treatment fast.

Question 2

Difficulty: medium

Describe a time you had to respond to a respiratory emergency. What did you do?

Sample answer

In a respiratory emergency, I stay focused on the basics and work calmly as part of the team. For example, if a patient suddenly becomes hypoxic or develops severe wheezing, I immediately check the equipment, verify the oxygen delivery device, and assess breath sounds and chest rise. I would call for additional help early if the patient looks like they are tiring out or if their mental status changes. From there, I’d support airway management, prepare medications or nebulizer therapy as ordered, and be ready for bag-mask ventilation if the patient cannot maintain adequate oxygenation. What matters most in those moments is staying organized and communicating clearly so everyone knows the next step. I also make sure to document the event thoroughly and participate in any debriefing afterward so we can improve response times and patient safety for the future.

Question 3

Difficulty: easy

How do you decide which oxygen delivery device to use for a patient?

Sample answer

I choose the device based on how severe the patient’s hypoxemia is, how much support they need, and whether they are able to breathe effectively on their own. For someone with mild oxygen needs, a nasal cannula may be enough. If they need a higher concentration, I might use a simple mask or nonrebreather depending on the situation and protocol. If the patient is in respiratory distress, I look beyond the number and assess work of breathing, respiratory rate, and overall clinical picture. I also consider the underlying condition, because a COPD patient may need careful titration to avoid over-oxygenation, while a trauma or acute distress patient may need faster escalation. I always reassess after starting oxygen to make sure it is working and adjust based on response. My goal is to use the least invasive option that still keeps the patient safe and stable.

Question 4

Difficulty: hard

What steps do you take when managing a patient on mechanical ventilation?

Sample answer

When managing a ventilated patient, I focus on safety, monitoring, and staying alert for changes. I start by checking the order, ventilator settings, patient-ventilator synchrony, alarms, and the patient’s overall condition. I assess breath sounds, chest rise, sedation level, oxygenation, and end-tidal CO2 if available. I also verify that the circuit is intact, humidification is appropriate, and suctioning is performed when needed. If alarms occur, I troubleshoot systematically instead of guessing—checking for disconnection, secretions, coughing, or possible changes in lung compliance. I pay close attention to trends in ABGs, tidal volumes, pressures, and the patient’s response to treatment. If something seems off, I escalate quickly and involve the physician or critical care team. I see ventilator care as a balance between technology and bedside assessment. The machine gives important data, but the patient always tells the full story.

Question 5

Difficulty: easy

How do you handle a patient who is anxious or scared about receiving respiratory treatment?

Sample answer

I try to slow the situation down for the patient without delaying care. A lot of patients are nervous when they hear the words oxygen, nebulizer, or ventilator, especially if they are struggling to breathe. I explain what I’m doing in simple terms, what they might feel, and how it is meant to help them. I keep my voice calm, make eye contact, and give the patient small goals, like taking slow breaths or relaxing their shoulders. If possible, I involve the family in a reassuring way while still protecting the patient’s privacy. I also pay attention to whether anxiety is making the breathing worse, because that can happen quickly. In those cases, I communicate with the nurse or provider so we can address both the respiratory issue and the emotional stress. Patients tend to cooperate better when they feel respected, informed, and not rushed.

Question 6

Difficulty: medium

Tell me about a time you had to educate a patient on inhaler use or home respiratory care.

Sample answer

Patient education is one of the most important parts of respiratory therapy because it directly affects outcomes after discharge. When I teach inhaler use, I never assume the patient already understands the technique. I demonstrate the steps, then have the patient show me back so I can catch mistakes like poor timing, not holding their breath, or using the wrong seal. I also explain the difference between rescue and maintenance inhalers in a way that makes sense to them. If the patient uses a spacer, oxygen, or nebulizer at home, I review cleaning, storage, and when to replace supplies. I keep the education practical and tied to their daily routine, because patients remember what feels realistic. I also ask about barriers like cost, transportation, or low confidence, and I try to connect them with resources when needed. Good teaching helps prevent readmissions and gives patients more control over their condition.

Question 7

Difficulty: hard

How do you prioritize care when you have multiple patients needing respiratory therapy services at the same time?

Sample answer

I prioritize by acuity and by what could become unsafe if delayed. The first patient I attend to is usually the one in immediate respiratory distress, with low oxygen saturation, increasing work of breathing, altered mental status, or an unstable airway. Next, I look at patients who are on vents, receiving time-sensitive treatments, or waiting for assessments that could change management. I also consider the risk of each task—some things seem routine but can become urgent quickly if a patient starts deteriorating. I communicate with nursing and other team members so no critical need is missed. If appropriate, I ask for help or delegate within scope to keep care moving efficiently. I’ve learned that being organized, checking the full assignment early, and reassessing often helps prevent problems from building up. Good prioritization is not just about speed; it is about recognizing what can wait and what absolutely cannot.

Question 8

Difficulty: hard

What would you do if a patient with COPD is retaining CO2 and becoming more drowsy?

Sample answer

If I saw a COPD patient becoming drowsy with signs of CO2 retention, I would treat it as a serious change and reassess immediately. I’d check respiratory rate, effort, oxygen saturation, breath sounds, recent oxygen settings, and any ABG or capnography data available. I would make sure the patient is receiving the prescribed oxygen safely and review whether their current support is enough or if they need escalation, such as bronchodilator therapy, airway clearance, or noninvasive ventilation if ordered and appropriate. I would also alert the provider promptly because changes in mental status can signal worsening ventilation, not just oxygenation. At the same time, I’d look for reversible causes like mucus plugging, fatigue, or infection. My approach is to avoid assumptions and respond to the whole clinical picture. COPD patients can decline gradually, so I believe close reassessment and early communication are key to preventing a more serious event.

Question 9

Difficulty: easy

How do you ensure you are following infection control and equipment cleaning standards in your daily work?

Sample answer

I treat infection control as a core part of respiratory therapy, not an extra task. Because we work with airways, secretions, and often high-risk patients, small lapses can have major consequences. I follow hand hygiene consistently, use appropriate personal protective equipment, and clean or replace equipment according to hospital policy and manufacturer guidelines. I’m careful with reusable items like masks, nebulizer equipment, and ventilator components, and I make sure circuits and disposable supplies are handled correctly between patients. I also pay attention to isolation precautions and confirm I’m using the right setup before entering the room. If I’m unsure about a cleaning protocol, I ask instead of guessing. I’ve found that being disciplined with infection control protects patients, coworkers, and myself, especially in critical care and pediatric settings. It also builds trust with the team because they know I’m reliable and detail-oriented with equipment and patient safety.

Question 10

Difficulty: easy

Why do you want to work as a Respiratory Therapist, and what makes you a strong fit for this role?

Sample answer

I want to work as a Respiratory Therapist because it combines hands-on patient care, critical thinking, and the ability to make a real difference in moments when patients are scared or struggling to breathe. I like that the role requires both technical skill and strong communication. You have to be comfortable with rapid changes, but also patient enough to teach and reassure people. I think I’m a strong fit because I’m calm under pressure, observant, and very consistent about reassessment and follow-through. I enjoy working with a team, but I also take ownership of my responsibilities and keep safety at the center of everything I do. I understand that respiratory care affects many parts of the hospital, from the emergency department to critical care to discharge education. That variety is something I value. I would bring a strong work ethic, attention to detail, and a patient-first approach to the role.
