Example Answers
Inotropic agents, such as dobutamine and milrinone, are medications that increase the heart's contractility, thereby improving cardiac output. They are used in acute heart failure when patients are experiencing low blood pressure and insufficient perfusion. It is important to monitor for side effects like arrhythmias and hypotension.
Explain the purpose of different modes of mechanical ventilation.
How to Answer
- 1
Start by defining mechanical ventilation and its importance in critical care.
- 2
Mention the main modes: Assist-Control (AC), Synchronized Intermittent Mandatory Ventilation (SIMV), and Continuous Positive Airway Pressure (CPAP).
- 3

- 5
Conclude with a brief implication of choosing the right mode for optimal patient outcomes.
Example Answers
Mechanical ventilation is crucial for supporting patients with respiratory failure. The main modes include Assist-Control, which provides full support for patients unable to initiate breaths, and SIMV, which allows for spontaneous breathing with some assisted breaths. CPAP maintains airway pressure but requires the patient to breathe spontaneously. Choosing the right mode is essential for optimizing ventilation while considering the patient's ability to breathe independently.
