Kettering- Therapeutic Procedures A Questions And Correct Answers |100% Verified |Guaranteed Success | 2025 update

1. Question: A patient is on a continuous flow CPAP system. The respiratory therapist notes that the pressure drops to zero during inspiration. The therapist should? Answer: Increase the flow to the patient. Explanation: Decrease pressures are mainly two primary problems anytime you are losing pressure its either a leak or not enough flow. Increase pressures would be opposite an obstruction or too much flow. 2. Question: A patient with a history of chronic hypercapnia is admitted to the emergency department complaining of shortness of breath and frequent coughing episodes. The patient is expectorating inspissated, pale yellow secretions. The respiratory therapist should recommend? Answer: Oxygen at 2L/min via nasal cannula. Explanation: We need to try to relief the patient from the shortness of breath. So, the emergent or first thing to do is to administer oxygen for the SOB and then take care of the sputum culture. 3. Question: A patient with known reversible airway disease takes two puffs of albuterol from his metered-dose inhaler. The respiratory therapist measures the patient's peak flow following the administration of the medication and determines that the peak flow has increased only minimally. The therapist should? Answer: Add a spacer to the metered-dose inhaler. Explanation: Since we know the patient has a reversible disease, we know that albuterol should help but the pt might not be getting the entire dose due to it might be lost in the air prior to getting to patient. With a spacer it will allow for the patient to inhale the entire dose of medication and have better efficiency. 4. Question: An H cylinder of oxygen has 1200 psi remaining in the tank. How long will it take to decrease to 200 psi if the flow is 5 L/min? Answer: 10 hours Explanation: 1200-200 is 1000psi multiply by the tank factor and then divide by the flow rate inmin and divide by 60 to get hours. The H cylinder tank factor is 3. So 1000 times 3 is 3000 then divide by 5 equals to 600 minutes and you divide by 60 to get 10 hours. 5. Question: While administering an IPPB treatment with a mouthpiece, the respiratory therapist notes that the patient is not reaching the preset pressure of 20 cm H2O. The therapist incorporated nose plugs with the therapy without success. The therapist should attempt to? Answer: Increase the flow in the system. Explanation: IPPB is always administered in the assist mode meaning the patient will trigger the breath. Often there is a leak. But since you plugged the nose that is normally where your leaks are with IPPB since you already took care of the leak then the next thing you would do is increase the flow. 6. Question: A 32-week gestational age neonate receives CPAP by nasal prongs at 4 cm H2O. During a routine bedside assessment, the respiratory therapist notes that the pressure manometer is reading zero. The therapist should? Answer: Confirm placement of the nasal prongs. Explanation: The key here is that the pressure is reading zero if the pressure was dropping then it would indicate a leak or flow issue. Since the pressure is zero that means some type of disconnect, we would initially check all connections before any other things are done. Since the pressure is at zero there is a major disconnect somewhere
