What is the primary goal of mechanical ventilation in acute respiratory failure?
Mechanical ventilation is primarily used to improve oxygenation and reduce carbon dioxide levels in patients with acute respiratory failure. It is not intended to replace pharmacological treatments, provide long-term support, or cure the underlying disease.
Which of the following conditions is commonly associated with acute respiratory distress syndrome (ARDS)?
ARDS is commonly associated with pneumonia, especially in severe cases where it leads to significant lung inflammation and damage. COPD, pulmonary embolism, and asthma are not primary conditions associated with ARDS.
Which diagnostic test is most useful for assessing myocardial infarction in critically ill patients?
An ECG is essential for assessing myocardial infarction by identifying characteristic changes in the heart’s electrical activity. Chest X-ray, CT scan, and CBC are used for other diagnostic purposes.
Which medication is commonly used for sedation in critically ill patients?
Lorazepam is commonly used for sedation in critically ill patients due to its effectiveness and safety profile. Metformin, lisinopril, and furosemide are used for other purposes, such as diabetes management, hypertension, and fluid management.
What is the most important monitoring parameter for a patient on continuous renal replacement therapy (CRRT)?
Fluid balance is crucial to monitor in patients on CRRT to ensure proper fluid removal and replacement, preventing complications such as fluid overload or dehydration. Heart rate, blood glucose, and liver function tests are less directly related to CRRT.
