CRE Respiratory Therapy & Intervention Techniques 1 — Questions and Answers
Question 1: What is the primary goal of respiratory therapy?
- To assist with digestive disorders.
- To improve respiratory function and relieve symptoms (Correct answer)
- To monitor blood pressure.
- To treat infections.
Correct answer: To improve respiratory function and relieve symptoms
The primary goal of respiratory therapy is to optimize the patient's breathing and overall respiratory health. This involves a range of interventions aimed at improving lung function, facilitating gas exchange, clearing airways, and alleviating symptoms such as shortness of breath, coughing, and wheezing. Ultimately, respiratory therapy strives to enhance the patient's quality of life and reduce the impact of respiratory conditions.
Question 2: What is the primary function of a nebulizer in respiratory therapy?
- It helps with blood circulation.
- It administers medication to the lungs in the form of a mist (Correct answer)
- It measures oxygen levels in the blood.
- It supports digestion.
Correct answer: It administers medication to the lungs in the form of a mist
A nebulizer is a medical device used in respiratory therapy to convert liquid medication into a fine mist, which can then be easily inhaled by the patient directly into their lungs. This method allows for targeted and efficient delivery of drugs like bronchodilators or corticosteroids, providing rapid relief for respiratory symptoms and treating conditions such as asthma or COPD.
Question 3: What is the role of mechanical ventilation in respiratory therapy?
- It helps with digestion.
- It provides assisted breathing for patients with respiratory failure (Correct answer)
- It increases the body temperature.
- It regulates blood pressure.
Correct answer: It provides assisted breathing for patients with respiratory failure
Mechanical ventilation is a life-sustaining treatment in respiratory therapy for patients experiencing respiratory failure, where their lungs cannot adequately perform gas exchange on their own. The ventilator assists or completely takes over the breathing process, ensuring sufficient oxygen delivery to the blood and removal of carbon dioxide, thereby supporting vital organ function and allowing the lungs to heal.
Question 4: What is a common treatment for asthma in respiratory therapy?
- Bronchodilators and corticosteroids are commonly used treatments for asthma (Correct answer)
- Blood pressure medications.
- Vitamins and supplements.
- Antibiotics.
Correct answer: Bronchodilators and corticosteroids are commonly used treatments for asthma
For asthma, a chronic inflammatory airway disease, the primary treatments in respiratory therapy involve bronchodilators and corticosteroids. Bronchodilators quickly relax the muscles around the airways to open them up and relieve acute symptoms, while corticosteroids reduce inflammation in the airways to prevent future attacks and manage long-term control of the condition.
Question 5: What is the purpose of positive pressure ventilation?
- It helps prevent infections.
- It helps maintain adequate ventilation and oxygenation (Correct answer)
- It increases body temperature.
- It aids in digestion.
Correct answer: It helps maintain adequate ventilation and oxygenation
Positive pressure ventilation (PPV) is a therapeutic technique that uses a mechanical ventilator to push air into the lungs, thereby increasing pressure within the airways. This helps to keep the alveoli open, improve gas exchange, and ensure that the patient receives adequate oxygenation and ventilation, especially in cases of respiratory distress or failure.
Question 6: Why is oxygen therapy important for patients with chronic obstructive pulmonary disease (COPD)?
- It decreases oxygen levels.
- It improves oxygenation and reduces symptoms of COPD (Correct answer)
- It helps with digestion.
- It reduces muscle tension.
Correct answer: It improves oxygenation and reduces symptoms of COPD
Oxygen therapy is crucial for patients with Chronic Obstructive Pulmonary Disease (COPD) because their damaged lungs often struggle to adequately absorb oxygen from the air. By providing supplemental oxygen, this therapy helps to increase the oxygen levels in the blood, reduce shortness of breath, improve exercise tolerance, and alleviate other debilitating symptoms associated with COPD, thereby enhancing quality of life.
Question 7: How does chest physiotherapy help patients with respiratory conditions?
- It promotes relaxation and reduces muscle stiffness.
- It helps clear mucus from the airways (Correct answer)
- It improves digestion.
- It helps improve eyesight.
Correct answer: It helps clear mucus from the airways
Chest physiotherapy (CPT) involves techniques like percussion and vibration applied to the chest wall. These methods physically dislodge and mobilize thick mucus or secretions that accumulate in the lungs due to various respiratory conditions. By loosening and moving these secretions towards larger airways, CPT makes it easier for patients to cough them out, thereby improving breathing and preventing infections.
Question 8: What is the role of inhaled corticosteroids in respiratory therapy?
- They reduce inflammation and prevent asthma attacks (Correct answer)
- They improve digestion.
- They increase blood sugar levels.
- They enhance muscle strength.
Correct answer: They reduce inflammation and prevent asthma attacks
Inhaled corticosteroids are anti-inflammatory medications delivered directly to the airways. Their primary role is to reduce the swelling and mucus production in the bronchial tubes, which are common issues in conditions like asthma and COPD. By controlling this underlying inflammation, they help prevent symptoms and reduce the frequency and severity of asthma attacks or exacerbations, acting as a long-term control medication.
Question 9: What is the purpose of a ventilator in respiratory care?
- It helps with digestion.
- It assists with breathing during respiratory distress (Correct answer)
- It reduces body temperature.
- It helps regulate heart rate.
Correct answer: It assists with breathing during respiratory distress
A ventilator is a medical device designed to provide mechanical assistance for breathing. When a patient's lungs are unable to adequately perform gas exchange due to severe respiratory distress or failure, the ventilator takes over or supports the work of breathing. It delivers oxygen and removes carbon dioxide, ensuring the patient receives sufficient air and allowing their lungs to rest and recover.
