20 questions
Question 1: Noninvasive Positive Pressure Ventilation (NPPV) is used for permanent life support ventilation.
A. Ano
B. Ne
Explanation: NPPV should not be used for life support ventilation; it is intended only to temporarily support the patient's own spontaneous breathing.
Question 2: A patient with ARDS is being mechanically ventilated. According to the study materials, which of the following ventilator settings and modes are recommended for managing ARDS?
A. Using low tidal volumes.
B. Maintaining high levels of PEEP.
C. Utilizing synchronous intermittent mandatory ventilation (SIMV) as the primary mode.
D. Targeting a low pH and higher PaCO2 (permissive hypercapnia) to avoid barotrauma.
Explanation: The study materials state under 'ARDS E. Treatment 2. Mechanical ventilation' that 'The most important principles include using a high PEEP with low tidal volumes'. Additionally, under 'Mechanical Ventilation A. General Characteristics 3.', it mentions that 'In some cases (such as ARDS), permissive hypercapnia may be the goal (targeting a lower pH and higher PaCO2 to avoid barotrauma)'. SIMV is not specifically recommended for ARDS and the materials note it 'May increase respiratory fatigue and prolonged mechanical ventilation'.
Question 3: Pulmonary hypertension caused by recurrent pulmonary embolism is classified under Group 3 of the revised WHO classification system.
A. Ano
B. Ne
Explanation: Pulmonary hypertension due to recurrent pulmonary embolism is classified under Group 4: Chronic thromboembolic disease. Group 3 includes lung disease and/or chronic hypoxemia.
Question 4: Which statement accurately describes a general characteristic of pulmonary hypertension?
A. It is defined as a mean pulmonary arterial pressure greater than 20 mm Hg at rest.
B. Left heart disease, such as mitral stenosis, is always considered a miscellaneous cause (Group 5).
C. Pulmonary hypertension solely results from passive resistance in the pulmonary venous system.
D. The prognosis for Group 1 Pulmonary Arterial Hypertension (PAH) is typically excellent with a high survival rate.
Explanation: Pulmonary hypertension is defined as a mean pulmonary arterial pressure greater than 20 mm Hg at rest, as stated in the study materials under 'A. General Characteristics 1'. Left heart disease is classified as Group 2, not Group 5. Pulmonary hypertension can result from multiple pathophysiologic processes, not solely passive resistance. The prognosis for Group 1 PAH is poor, with a mean survival of 2 to 3 years from diagnosis, not excellent.
Question 5: The PIOPED study provides guidelines for treatment when a V/Q scan is performed for suspected pulmonary embolism.
A. Ano
B. Ne
Explanation: The study materials explicitly state under 'Quick HIT' that 'The Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) is a landmark study (JAMA 1990;263:2753). Guides treatment, if V/Q is performed.' Additionally, under the V/Q scan section, it notes that 'treatment guidelines based on PIOPED study' are used for interpreting V/Q scan results.
