#1
Which of the following is NOT a symptom of pulmonary hypertension?
Fever
ExplanationFever is not typically associated with pulmonary hypertension.
#2
What is the primary cause of pulmonary hypertension?
Vasoconstriction in the pulmonary arteries
ExplanationPulmonary hypertension primarily stems from vasoconstriction within the pulmonary arteries.
#3
Which chamber of the heart is primarily affected by pulmonary hypertension?
Right ventricle

#5
Which of the following conditions is commonly associated with pulmonary hypertension?
Pulmonary fibrosis

#6
Which of the following is NOT a classification group of pulmonary hypertension according to the WHO?
Group 7: Pulmonary hypertension due to genetic disorders
ExplanationGroup 7, pulmonary hypertension due to genetic disorders, is not recognized by the WHO classification.
#7
Which of the following is a potential complication of untreated pulmonary hypertension?

ExplanationHeart failure is a possible complication if pulmonary hypertension remains untreated.
#8
What is the mean pulmonary arterial pressure (mPAP) threshold for diagnosing pulmonary hypertension?
≥ 25 mmHg at rest
ExplanationA mean pulmonary arterial pressure of 25 mmHg or higher at rest is the diagnostic threshold for pulmonary hypertension.
#9
What is the pathophysiological hallmark of pulmonary hypertension?
Increased pulmonary vascular resistance
ExplanationAn elevation in pulmonary vascular resistance is the hallmark of pulmonary hypertension.
#10
What is the gold standard diagnostic test for pulmonary hypertension?
Right heart catheterization
ExplanationRight heart catheterization stands as the gold standard diagnostic test for pulmonary hypertension.
#11
Which of the following is a potential complication of pulmonary hypertension during pregnancy?

ExplanationPulmonary edema is a potential complication of pulmonary hypertension during pregnancy.
#12
What is the mechanism of action of endothelin receptor antagonists in the treatment of pulmonary hypertension?
Vasodilation of pulmonary arteries
ExplanationEndothelin receptor antagonists function by inducing vasodilation of pulmonary arteries in pulmonary hypertension treatment.
#13
Which of the following diagnostic tests can help differentiate between pulmonary arterial hypertension and pulmonary venous hypertension?
Echocardiography
ExplanationEchocardiography aids in differentiating between pulmonary arterial hypertension and pulmonary venous hypertension.
