#1
Which of the following is an essential step in airway management?
Maintaining an open airway
ExplanationEnsuring proper airflow to the lungs is crucial for oxygenation and preventing respiratory failure.
#2
What is the primary purpose of a nasopharyngeal airway?
To maintain an open airway in unconscious patients
ExplanationIt helps prevent airway obstruction by keeping the tongue from falling back in unconscious patients.
#3
What is the purpose of a nebulizer in respiratory care?
To deliver inhaled medications in aerosolized form
ExplanationIt's an effective way to administer medications directly to the lungs for respiratory conditions.
#4
Which of the following is a potential complication of endotracheal intubation?
Aspiration of gastric contents
ExplanationIt occurs when stomach contents enter the lungs, potentially leading to pneumonia or lung damage.
#5
What is the purpose of a high-flow nasal cannula in respiratory care?
To deliver a high concentration of oxygen with humidification
ExplanationIt provides oxygen therapy at higher flow rates, improving oxygenation while maintaining comfort.
#6
What is the primary goal of bag-valve-mask ventilation?
Providing positive pressure ventilation
ExplanationIt's aimed at assisting or providing ventilation to patients who cannot breathe adequately on their own.
#7
In respiratory care, what does the term 'PEEP' stand for?
Positive End-Expiratory Pressure
ExplanationIt helps keep the airways open and improves oxygenation during mechanical ventilation.
#8
Which respiratory condition is characterized by inflammation and narrowing of the airways?
Chronic obstructive pulmonary disease (COPD)
ExplanationIt's a chronic condition that obstructs airflow in the lungs, leading to breathing difficulties.
#9
What does the term 'FiO2' represent in the context of respiratory care?
Fraction of Inhaled Oxygen
ExplanationIt indicates the percentage of oxygen in the air being breathed.
#10
Which respiratory parameter is measured by a spirometer?
Peak expiratory flow rate
ExplanationIt assesses the maximum speed of expiration, often used to monitor lung function.
#11
What is the primary function of the epiglottis in airway anatomy?
To prevent food and liquid from entering the trachea
ExplanationIt acts as a lid to cover the trachea during swallowing, directing food and liquids down the esophagus.
#12
Which device is commonly used to measure the oxygen saturation level in a patient?
Pulse oximeter
ExplanationIt provides a quick and non-invasive method to assess oxygen levels in the blood.
#13
What is the purpose of intubation in airway management?
To secure and maintain a patent airway
ExplanationIt's a crucial procedure to ensure a clear passage for airflow, particularly in critically ill or unconscious patients.
#14
In mechanical ventilation, what does the acronym 'ARDS' stand for?
Acute Respiratory Distress Syndrome
ExplanationIt's a severe lung condition that causes difficulty in breathing due to fluid buildup in the lungs.
#15
Which technique is commonly used for airway clearance in patients with cystic fibrosis?
Postural drainage and percussion
ExplanationIt helps dislodge and remove thick, sticky mucus from the lungs, improving breathing.
#16
Which condition is characterized by the collapse of small airways and alveoli during expiration?
Emphysema
ExplanationIt's a progressive lung disease that damages the air sacs in the lungs, making it difficult to breathe out.
#17
What is the purpose of a chest physiotherapy vest in respiratory care?
To assist with airway clearance through oscillations
ExplanationIt helps loosen and remove mucus from the airways by delivering vibrations to the chest.
