SECTION A: MULTIPLE CHOICE QUESTIONS (30 Questions) ly ly ly ly ly ly




1. Which healthcare professional is primarily responsible for the daily
ly ly ly ly ly ly ly ly ly




ly management and adjustment of mechanical ventilation in the ICU? ly ly ly ly ly ly ly ly




 A) Critical care nurse
ly ly ly




 B) Intensivist physician
ly ly




 C) Respiratory therapist
ly ly




 D) Physical therapist
ly ly




Answer: C) Respiratory therapists are specifically trained in the science of respiratory
ly ly ly ly ly ly ly ly ly ly ly




care, including ventilator management, airway maintenance, and blood gas analysis,
ly ly ly ly ly ly ly ly ly ly




making them the primary practitioners for daily ventilator adjustments under physician
ly ly ly ly ly ly ly ly ly ly ly




orders.

2. What was the first widely used mechanical ventilator that operated on the
ly ly ly ly ly ly ly ly ly ly ly ly




ly principle of negative pressure? ly ly ly




 A) Bird Mark 7
ly ly ly




 B) Iron lung (Drinker respirator)
ly ly ly ly




 C) Bennett PR-2
ly ly

, D) Servo 900C
ly ly




Answer: B) The Drinker respirator, commonly known as the iron lung, was developed in
ly ly ly ly ly ly ly ly ly ly ly ly ly




the 1920s and used negative pressure to create a vacuum around the chest, causing
ly ly ly ly ly ly ly ly ly ly ly ly ly ly




inspiration. It became iconic during the polio epidemics before modern positive-
ly ly ly ly ly ly ly ly ly ly ly




pressure ventilators replaced it.

3. Which of the following is a primary goal of mechanical ventilation?
ly ly ly ly ly ly ly ly ly ly ly




 A) Cure the underlying pulmonary disease
ly ly ly ly ly




 B) Maintain adequate alveolar ventilation and arterial oxygenation
ly ly ly ly ly ly ly




 C) Eliminate the need for sedation
ly ly ly ly ly




 D) Reduce the patient's cardiac output
ly ly ly ly ly




Answer: B) The primary goals are to support gas exchange (ventilation and
ly ly ly ly ly ly ly ly ly ly ly




oxygenation), relieve respiratory distress, and allow lung healing while minimizing
ly ly ly ly ly ly ly ly ly ly




iatrogenic injury. It does not cure disease nor eliminate sedation needs.

4. The multidisciplinary ICU team typically includes all of the following EXCEPT:
ly ly ly ly ly ly ly ly ly ly ly




 A) Respiratory therapist
ly ly




 B) Clinical pharmacist
ly ly




 C) Hospital administrator
ly ly




 D) Registered dietitian
ly ly




Answer: C) While administrators oversee operations, they are not part of the direct daily
ly ly ly ly ly ly ly ly ly ly ly ly ly




patient-care multidisciplinary rounding team. The core team includes physicians, nurses,
ly ly ly ly ly ly ly ly ly ly




respiratory therapists, pharmacists, dietitians, and social workers.

, 5. Which mode of ventilation delivers a set tidal volume with each mandatory
ly ly ly ly ly ly ly ly ly ly ly ly




ly breath but allows the patient to trigger additional breaths?
ly ly ly ly ly ly ly ly




 A) Assist-Control (AC)
ly ly




 B) Pressure Support Ventilation (PSV)
ly ly ly ly




 C) Continuous Positive Airway Pressure (CPAP)
ly ly ly ly ly




 D) High-Frequency Oscillatory Ventilation (HFOV)
ly ly ly ly




Answer: A) Assist-Control ventilation delivers a preset tidal volume for every breath—
ly ly ly ly ly ly ly ly ly ly ly




whether initiated by the machine (control) or triggered by the patient (assist). PSV
ly ly ly ly ly ly ly ly ly ly ly ly




provides pressure support, CPAP is spontaneous breathing with PEEP, and HFOV uses
ly ly ly ly ly ly ly ly ly ly ly ly




very high frequencies with small tidal volumes.
ly ly ly ly ly ly ly




6. What does PEEP stand for in mechanical ventilation?
ly ly ly ly ly ly ly ly




 A) Peak End-Expiratory Pressure
ly ly ly




 B) Positive End-Expiratory Pressure
ly ly ly




 C) Pulmonary Expiratory Equilibrium Pressure
ly ly ly ly




 D) Pressure-cycled Expiratory Phase
ly ly ly




Answer: B) Positive End-Expiratory Pressure is the application of positive pressure at the
ly ly ly ly ly ly ly ly ly ly ly ly




end of expiration to prevent alveolar collapse (atelectasis), improve oxygenation, and
ly ly ly ly ly ly ly ly ly ly ly




increase functional residual capacity.
