An RT asks a patient with COPD about their smoking habits. The patient states, I know smoking is bad for me and I've been thinking about quitting next month. According to the Transtheoretical Model, what stage of change is this?
A 60-year-old male with a history of sandblasting and glass manufacturing presents with progressive dyspnea and eggshell calcifications on a chest X-ray. What specific occupational lung disease is most likely?
A patient's Asthma Action Plan indicates they are in the Yellow Zone based on their Peak Expiratory Flow (PEF) readings. What percentage of their personal best does this represent, and what is the required immediate action?
A post-operative hip surgery patient suddenly develops pleuritic chest pain and tachypnea. Which three specific risk factors in the patient's history would most strongly increase the clinical suspicion for a Pulmonary Embolism (PE)?
A 32-year-old non-smoker presents with symptoms of emphysema and a family history of early-onset liver disease. Which genetic deficiency should the RT suspect as the primary risk factor?
An intubated patient has been on mechanical ventilation for 72 hours. Which historical and assessment factors increase the risk for Ventilator-Associated Pneumonia (VAP), and which modifiable risk factor is often tested?
A patient reports smoking 30 cigarettes per day for 15 years, followed by 10 cigarettes per day for the last 10 years. What is the patient's total pack-year history?
During a routine assessment, a patient states, "I know smoking is bad for my COPD, but I'm not ready to quit right now." According to the 5 A's and 5 R's, what is the most appropriate next step?
A patient participating in a smoking cessation program provides an exhaled carbon monoxide (CO) reading of 12 ppm. How should the Respiratory Therapist interpret this result?
Which pharmacological intervention is currently considered the most effective monotherapy for long-term smoking cessation success in 2026 clinical guidelines?
A 55-year-old patient with a 25 pack-year history quit smoking 10 years ago. According to current USPSTF and NBRC standards, does this patient qualify for annual Lung Cancer Screening (LCS)?
A heavy smoker presents to the ED with shortness of breath. The SpO2 is 98% on room air, but the patient appears cyanotic. What is the most likely reason for this discrepancy?
A patient in a smoking cessation program reports intense cravings, irritability, and insomnia 48 hours after their last cigarette. Which stage of the Transtheoretical Model is this patient currently in?
A patient is prescribed nicotine patches but continues to experience "breakthrough" cravings in the morning. What adjustment to the cessation plan is most evidence-based?

Which physiological effect of nicotine contributes most directly to the increased cardiovascular risk observed in smokers?
72yo COPD patient in respiratory failure has a documented DNR/DNI order. The patient is currently tachypneic and hypoxic (SpO2 84%). What is the most appropriate RT intervention?
A patient is unconscious with no advance directive. The spouse wants to continue ventilation, but the adult child wants to withdraw. Who has the legal authority to decide?
An RT refuses to perform an arterial puncture on a combative patient who is clearly refusing the procedure, despite a physician's order. Which ethical principle is the RT upholding?
A terminal lung cancer patient has a Living Will stating no life-prolonging measures. The Healthcare Proxy (DPOA) demands the patient be intubated for acute failure. Which takes precedence?
During an exacerbation, a patient with a written DNR order tells the RT, I changed my mind, do everything to save me. What is the RT's immediate legal obligation?
A physician asks an RT to slow code a terminal patient because the family won't agree to a DNR. Why is this practice ethically and legally problematic?
What specific information must be provided to a patient to satisfy the requirements of Informed Consent before an invasive procedure like a bronchoscopy?
An RT administers high-dose opioids to a terminal patient to relieve severe dyspnea, knowing it may suppress respiratory drive. Which ethical principle justifies this action?
How does a POLST (Physician Orders for Life-Sustaining Treatment) differ from a standard Living Will in the acute care setting?
A patient's family demands everything be done for a brain-dead patient on a ventilator. The medical team deems further care medically futile. What is the next ethical step?

I know exactly how heavy that feeling in the pit of your stomach can get when you look at the mountain of material required for the Crt exam. In my years mentoring clinical professionals through their certifications, I have seen brilliant colleagues doubt themselves simply because the scope of content feels unmanageable. Whether you are reviewing complex blood gas QC protocols or trying to keep your pharmacology classifications straight, it is a lot to carry. That is why I put together this free previewβto give you a manageable starting point rather than throwing you into the deep end. In this set of 30 free practice questions, I have selected a mix of topics that reflect the actual challenges you will face on the exam. We touch on critical areas like diagnostics, pathology, and emergency management. While the full collection holds 1,040 cards, these initial questions are designed to help you gauge where you stand right now. Think of this as a diagnostic tool for your own knowledge base. Are you solid on your patient assessment techniques but a bit shaky on monitoring equipment? This preview will help you identify those gaps early without any pressure. When you work through these cards, I want you to focus on more than just getting the answer right. In my experience, the most successful candidates are the ones who stop to ask themselves why an answer is correct. If you encounter a question on mechanical ventilation procedures or airway management, take a moment to visualize the clinical scenario. Connect the dry facts on the screen to the patients you have cared for or observed. This context-based learning is far more sticky than rote memorization. I have found that consistency beats intensity every time. It is better to review ten cards with your morning coffee than to cram for five hours on a Sunday. These flashcards are built to support that kind of daily, bite-sized habit. By breaking down complex subjects like blood gas interpretation into single, focused concepts, we make the information easier to digest and retain long-term. You do not need to master everything in one day. Take a deep breath and start with these free questions. You have already done the hard work of gaining clinical experience; now it is just about refining that knowledge for the test. You can do this, and I am here to help guide you through it.
