FREE RRT MCQ Questions And Answers
Which of the following conditions might require the use of a ventilator?
Pneumonia is an infection that can lead to difficulty breathing and may require ventilator support.
What is the role of a respiratory therapist in pulmonary rehabilitation programs?
Respiratory therapists play a role in designing exercise programs to improve lung function and overall health.
Which of the following is a sign of respiratory distress?
Rapid breathing is a common symptom of respiratory distress as the body tries to get more oxygen.
Which of the following arterial blood gas (ABG) readings (on 4 L/min O2 through nasal cannula) best demonstrates acute or chronic lung disease?
These findings demonstrate how an enhanced HCO3 level somewhat offsets the slightly increased acidity caused by a high CO2 level. The reduced PaCO2 indicates ""acute"". The high HCO2 indicates a ""chronic"" condition.
Which of the following devices might a respiratory therapist use to deliver a precise amount of oxygen to a patient?
A Venturi mask delivers a specific oxygen concentration to a patient and is commonly used in respiratory therapy.
Despite wearing a venturi mask that provides a FiO2 of 0.45 and a SpO2 of 87%, the patient in your care has proper tidal volumes, clean bilateral breath sounds throughout his lung fields, a normal CBC, and no signs or symptoms of infection. Although he is not currently taking an anticoagulant, the patient's file indicates a history of a clotting condition. Which examination would you advise getting done next?
The patient's medical history and present state point to a ventilation/perfusion issue, possibly a pulmonary embolism. Calculating the Pa and Pa difference reveals this. The clotting disorder suggests that PE might exist. The results of the other tests are not likely to show the existence or absence of a pulmonary embolism.
You discover traces of blood on the dressing between the stoma and the tube flange while providing routine care to a patient who has a tracheostomy. Which of these is the right move to take?
Trace amounts of blood on the dressing could be a sign of an infection, granuloma, or another stoma-related issue. While not an emergency, it is crucial that the doctor is informed. The patient record needs to reflect it.
What does the term "ARDS" stand for in respiratory care?
ARDS is a severe lung condition that causes rapid breathing, difficulty getting enough air, and low blood oxygen levels.
What is the purpose of a pulmonary function test?
Pulmonary function tests measure how well the lungs are working and can help diagnose respiratory conditions.
Which of these tests should the doctor order to find out a patient's functional residual capacity (FRC)?
None of the other examinations can quantify FRC. Only when the total lung capacity, which can be determined by body plethysmography or nitrogen washout, is known can the FRC be calculated.
A patient with a productive cough, a fever, and bilateral rhonchi in the lower lobes arrives to the ED of your hospital. The radiologist claims that the CXR may demonstrate bilateral infiltration. What quantity of white blood cells (WBCs) per microliter (mcL) would we anticipate to detect to establish a diagnosis of pneumonia?
White blood cell counts typically fall within a range of 4,500 to 10,000. Since pneumonia is an infectious disease, we would anticipate to find high white blood cell counts of more than 10,000 WBC/mcL. In most cases, bacterial and viral illnesses will increase the WBC count.
When a patient's SpO2 falls from 90% to 85% while they are being monitored in the telemetry unit, an alarm is triggered. The patient is equipped with a disposable inner cannula, a No. 6 Shiley tracheostomy tube, and a deflated cuff. What is the first thing you have to do when you walk into her room?
The patient must be evaluated when an oxygen saturation warning goes off since pulse oximetry requires precise skin contact and is frequently erroneous because to patient movement, skin hair, patient diaphoresis, or sensor connections. Check the location of the pulse oximetry probe and observe the patient for any indications of respiratory distress. The next action would be to suction the tracheostomy tube if the patient showed signs of distress.
Which of the following is a common technique used by respiratory therapists to help clear mucus from the airways?
Percussion therapy involves tapping the chest to loosen and help move mucus from the airways.
Which of the following is a respiratory therapist's responsibility in the case of a premature newborn with underdeveloped lungs?
Premature newborns with underdeveloped lungs might require intubation and ventilator support, which respiratory therapists can assist with.
A female patient, age 50, appears with a three-month history of a cough that produces phlegm and is worse in the morning after getting up. The sputum has a little to moderate amount, a middling consistency, and a pale yellow tint. No recent ill contacts or fever are present. Rhonchi are sometimes heard bilaterally during auscultation, particularly in the lower lobes. The patient has never smoked. What do you suggest?
The patient is displaying the classic signs and symptoms of chronic bronchitis-related COPD. She does not smoke, but smokers are not the only people who can get this chronic illness. It is also believed that a family history of COPD and ongoing lung irritation are contributing factors. A specific drug regimen cannot be advised due to a lack of information. Fever and an abrupt onset are two common clinical signs of pneumonia. It is not possible to recommend pulmonary rehabilitation until the illness is identified.
What is the primary purpose of a nasal cannula?
A nasal cannula is a device used to deliver supplemental oxygen to patients.
