Artificial Respiration MCQ Quiz | Respiratory System

Welcome to the Artificial Respiration MCQ Quiz, a specialized assessment tool for MBBS students studying the Respiratory System. This quiz is designed to test your understanding of both fundamental and advanced concepts, from basic life support techniques like CPR and bag-valve-mask ventilation to the complexities of mechanical ventilation, including modes, parameters, and potential complications. You will encounter 25 meticulously crafted questions covering historical methods, physiological principles, and clinical applications. After completing the quiz, you can submit your answers to see your score and review which questions you answered correctly or incorrectly. For your future reference and study, an option to download all questions with their correct answers in a PDF format is also provided. Good luck!

1. Mouth-to-mouth resuscitation is an example of which type of artificial respiration?

3. Which of the following is a major risk associated with bag-valve-mask (BVM) ventilation?

Barotrauma

Gastric insufflation

Hypocapnia

Metabolic acidosis

4. PEEP (Positive End-Expiratory Pressure) in mechanical ventilation primarily helps to:

Increase tidal volume

Decrease airway resistance

Prevent alveolar collapse

Trigger patient breaths

5. In the context of mechanical ventilation, “tidal volume” refers to:

The volume of air in the lungs after maximal inspiration

The volume of air delivered with each breath

The total volume of air exhaled per minute

The volume of air remaining after a normal expiration

6. Which method of artificial respiration is considered obsolete and potentially harmful due to risk of internal injury?

Silvester’s method

Holger Nielsen method

Schafer’s method

Mouth-to-mouth resuscitation

7. The “iron lung” is a historical example of what type of ventilator?

Positive pressure ventilator

Negative pressure ventilator

High-frequency jet ventilator

Oscillatory ventilator

8. Which of the following is a primary indication for initiating mechanical ventilation?

Mild asthma

Acute respiratory failure

Chronic bronchitis

Pneumonia with normal oxygen saturation

9. In assist-control (A/C) mode of ventilation, a breath can be triggered by:

Only the patient’s inspiratory effort

Only a preset timer

Both the patient’s inspiratory effort and a preset timer

Only by an external manual trigger

10. Barotrauma, a complication of mechanical ventilation, is most directly related to excessive:

Tidal volume

Respiratory rate

Airway pressure

Oxygen concentration (FiO2)

11. What is the primary physiological goal of artificial respiration?

To restore consciousness

To maintain adequate gas exchange

To increase blood pressure

To stimulate the diaphragm

12. The FiO2 (Fraction of Inspired Oxygen) for room air is approximately:

16%

21%

78%

100%

13. In Silvester’s method of artificial respiration, inspiration is achieved by:

Pressing on the patient’s back

Pressing on the patient’s chest

Raising the patient’s arms above their head

Performing abdominal thrusts

14. A patient on a ventilator develops a sudden drop in blood pressure. Which complication should be suspected first?

Oxygen toxicity

Tension pneumothorax

Mucus plugging

Ventilator-associated pneumonia

15. The “C-E” clamp technique is used during:

Endotracheal intubation

Bag-valve-mask ventilation

Chest compressions

Cricothyrotomy

16. The normal I:E (Inspiratory:Expiratory) ratio for a spontaneously breathing adult is typically:

2:1

1:1

1:2

1:4

17. What does SIMV stand for in the context of mechanical ventilation?

Synchronized Intermittent Mandatory Ventilation

Spontaneous Inspiratory Mandatory Ventilation

Simple Intermittent Mechanical Ventilation

Systemic Inspiratory Minute Volume

18. Hyperventilation during artificial respiration can lead to which acid-base disturbance?

Respiratory acidosis

Respiratory alkalosis

Metabolic acidosis

Metabolic alkalosis

19. Which parameter is most crucial for monitoring the adequacy of ventilation in a mechanically ventilated patient?

Arterial PO2

Oxygen Saturation (SpO2)

Heart Rate

Arterial PCO2

20. The Holger Nielsen method is a prone pressure method of artificial respiration. Expiration is facilitated by:

Lifting the patient’s arms

Applying pressure to the patient’s back

Rocking the patient

Tilting the patient’s head back

21. A major advantage of positive pressure ventilation over negative pressure ventilation is:

It more closely mimics natural breathing

It has fewer cardiovascular side effects

It does not require encasing the patient’s body

It carries a lower risk of barotrauma

22. The term for lung injury caused by overdistention of alveoli during mechanical ventilation is:

Atelectrauma

Biotrauma

Barotrauma

Volutrauma

23. The Guedel airway (oropharyngeal airway) is used to:

Prevent the tongue from obstructing the upper airway

Isolate the trachea for mechanical ventilation

Administer medications directly into the lungs

Prevent aspiration of gastric contents

24. During mouth-to-mouth resuscitation, what is the purpose of pinching the patient’s nose?

To stimulate the breathing reflex

To prevent air from escaping through the nostrils

To check for nasal obstruction

To protect the rescuer from infection

25. Weaning from mechanical ventilation is the process of:

Increasing the level of sedation

Switching to a more aggressive ventilation mode

Gradually transitioning the patient back to spontaneous breathing

Removing the endotracheal tube immediately
