A 57-year-old man is admitted to the burn unit after he was brought to the emergency room following an accidental fire in his house. His past medical history is unknown due to his current clinical condition. Currently, his blood pressure is 75/40 mmHg, pulse rate is 140/min, and respiratory rate is 17/min. The patient is subsequently intubated and started on aggressive fluid resuscitation. A Swan-Ganz catheter is inserted to clarify his volume status. Which of the following hemodynamic parameters would you expect to see in this patient?
ACardiac output: ↓, systemic vascular resistance: ↔, pulmonary artery wedge pressure: ↔
BCardiac output: ↑, systemic vascular resistance: ↑, pulmonary artery wedge pressure: ↔
CCardiac output: ↑, systemic vascular resistance: ↓, pulmonary artery wedge pressure: ↔
DCardiac output: ↓, systemic vascular resistance: ↑, pulmonary artery wedge pressure: ↓
ECardiac output: ↔, systemic vascular resistance: ↔, pulmonary artery wedge pressure: ↔
A 53-year-old man presents to the office for a routine examination. The medical history is significant for diabetes mellitus, for which he is taking metformin. The medical records show blood pressure readings from three separate visits to fall in the 130–160 mm Hg range for systolic and 90–100 mm Hg range for diastolic. Prazosin is prescribed. Which of the following are effects of this drug?
AVasodilation, decreased heart rate, bronchial constriction
