#1
Which of the following is a common sign of respiratory distress?
Cyanosis
ExplanationBluish discoloration of the skin due to inadequate oxygenation of the blood.
#2
What is the primary goal of cardiopulmonary resuscitation (CPR)?
To maintain circulation of oxygenated blood to vital organs
ExplanationTo restore blood flow and oxygenation to vital organs during cardiac arrest.
#3
Which of the following is a primary function of the respiratory system?
Exchange of gases
ExplanationProcess of oxygen and carbon dioxide exchange between the body and the environment.
#4
Which of the following is NOT a common symptom of a heart attack?
Sudden loss of vision
ExplanationHeart attacks typically do not cause sudden loss of vision.
#5
What is the purpose of the nasal cavity in the respiratory system?
To humidify and filter air
ExplanationPrepares air for the respiratory system by warming, humidifying, and filtering.
#6
Which of the following best describes the term 'hypoxia'?
Insufficient oxygen at the tissue level
ExplanationInadequate oxygen supply to body tissues.
#7
What is the function of the diaphragm during respiration?
To contract and relax, causing changes in thoracic volume
ExplanationPrincipal muscle involved in breathing, contracting to increase thoracic volume during inhalation.
#8
What is the recommended ratio of chest compressions to rescue breaths in adult CPR?
30 compressions to 2 breaths
ExplanationStandard ratio for effective cardiopulmonary resuscitation.
#9
What is the medical term for a collapsed lung?
Pneumothorax
ExplanationPresence of air in the pleural cavity, leading to lung collapse.
#10
Which of the following conditions is characterized by a sudden, severe, and sharp chest pain that worsens with breathing or coughing?
Pleurisy
ExplanationInflammation of the pleura, causing sharp pain aggravated by breathing.
#11
Which of the following is NOT a symptom of anaphylaxis?
Decreased blood glucose levels
ExplanationAnaphylaxis typically causes increased blood glucose levels due to stress response.
#12
Which of the following is a characteristic feature of acute respiratory distress syndrome (ARDS)?
Hypoxemia that does not respond to supplemental oxygen
ExplanationSevere respiratory failure with inadequate oxygenation despite oxygen therapy.
#13
Which of the following is a potential complication of administering high-flow oxygen therapy?
Hypercarbia
ExplanationIncreased carbon dioxide levels in the blood due to reduced respiratory drive.
#14
What is the primary treatment for tension pneumothorax?
Immediate needle decompression
ExplanationEmergency procedure to release trapped air in the pleural cavity.
#15
Which of the following is a characteristic of Cheyne-Stokes breathing?
Periods of apnea followed by gradually increasing respiratory effort
ExplanationPattern of breathing with cycles of progressively deeper and shallower breaths.
