Adult Critical Care Specialty (ACCS) Practice Exam

In the case of respiratory distress, which PAP value suggests potential pulmonary hypertension?

1. 25/8

2. 45/25

3. 15/5

4. 30/15

The correct answer is: 45/25

The correct choice indicates a pulmonary artery pressure (PAP) value that is significantly elevated compared to the normal range. Typical normal pulmonary artery pressures are around 20-25 mmHg for the systolic component and 8-12 mmHg for the diastolic component. In this context, a PAP value of 45/25 mmHg suggests a significant elevation in pulmonary artery pressure, which is indicative of pulmonary hypertension. This elevation in pressure can lead to impaired gas exchange, right ventricular strain, and further complications if not managed effectively. The other values listed fall within or close to the normal range for pulmonary pressure. For instance, 25/8 and 30/15 are elevated but do not reach the level typically associated with pulmonary hypertension. Meanwhile, 15/5 indicates lower pressures that are unlikely to be associated with pulmonary hypertension. Understanding these distinctions is crucial for recognizing and managing respiratory distress associated with increased pulmonary pressures.
