A 16-year-old girl is brought to the emergency room with hyperextension of the cervical spine caused by a trampoline injury. After ruling out the possibility of hemorrhagic shock, she is diagnosed with quadriplegia with neurogenic shock. The physical examination is most likely to reveal which of the following constellation of findings?
APulse: 110/min; blood pressure: 88/50 mm Hg; respirations: 26/min; normal rectal tone on digital rectal examination (DRE); normal muscle power and sensations in the limbs
BPulse: 116/min; blood pressure: 80/40 mm Hg; respirations: 16/min; loss of rectal tone on DRE; reduced muscle power and absence of sensations in the limbs
CPulse: 54/min; blood pressure: 88/44 mm Hg; respirations: 26/min; increased rectal tone on DRE; normal muscle power and sensations in the limbs
DPulse: 99/min; blood pressure: 188/90 mm Hg; respirations: 33/min; loss of rectal tone on DRE; reduced muscle power and absence of sensations in the limbs
EPulse: 56/min; blood pressure: 88/40 mm Hg; respirations: 22/min; loss of rectal tone on DRE; reduced muscle power and absence of sensations in the limbs
A 28-year-old research assistant is brought to the emergency department for severe chemical burns 30 minutes after accidentally spilling hydrochloric acid on himself. The burns cover both hands and forearms. His temperature is 37°C (98.6°F), pulse is 112/min, respirations are 20/min, and blood pressure is 108/82 mm Hg. Initial stabilization and resuscitation is begun, including respiratory support, fluid resuscitation, and cardiovascular stabilization. The burned skin is irrigated with saline water to remove the chemical agent. Which of the following is the most appropriate method to verify adequate fluid infusion in this patient?
AThe Parkland formula
BBlood pressure
CPulmonary capillary wedge pressure
DHeart rate
EUrinary output
A 27-year-old man is brought to the emergency department 30 minutes after being shot in the abdomen during a violent altercation. His temperature is 36.5°C (97.7°F), pulse is 118/min and regular, and blood pressure is 88/65 mm Hg. Examination shows cool extremities. Abdominal examination shows a 2.5-cm entrance wound in the left upper quadrant at the midclavicular line, below the left costal margin. Focused ultrasound shows free fluid in the left upper quadrant. Which of the following sets of hemodynamic changes is most likely in this patient? Cardiac output (CO) | Pulmonary capillary wedge pressure (PCWP) | Systemic vascular resistance (SVR) | Central venous pressure (CVP)
