What is the goal “door to balloon” time for percutaneous coronary intervention (PCI)?
90 minutes
What is the classic auscultatory feature of mitral valve prolapse?
Midsystolic click
What electrocardiogram finding is associated with hypocalcemia?
Prolonged QT interval.
After how many days should sutures of an eyelid laceration be removed?
3 to 5 days.
How should hypoxia in a patient with pulmonary hypertension be treated?
Supplemental oxygen only. Noninvasive positive pressure ventilation and intubation should be considered last resorts.
What organism should be suspected as a cause of necrotizing soft tissue infection if the patient sustained trauma in a saltwater environment?
Vibrio vulnificus.
What type of animal bite wounds require immediate postexposure prophylaxis for rabies?
Bite wounds sustained from a bat, raccoon, skunk, or fox.
Transcutaneous Cardiac Pacing- initial capture settings
40 to 60 mA to capture
set at max mA if unstable and decrease until threshold reached
What patient characteristics are more likely in those presenting with a de Winter ECG pattern?
These patients are typically younger, more often male, and more likely to have hypercholesterolemia compared with those who presented with classic ST elevation.
de Winter Syndrome
Acute LAD occlusion Upsloping ST elevation in aVR ST segment depression in the precordial lead with tall, positive, symmetric T waves STEMI equivalent Consult cardiology
A _________ is a fracture of the distal radius with dorsal and radial displacement of the wrist and hand and typically originates from a fall on an outstretched hand
Colles fracture
A _______ is a fracture of the proximal third of the ulna with a radial head dislocation.
Monteggia fracture
generally treated with open reduction and internal fixation of the ulna with closed reduction of the radial head dislocation.
a fracture of the middle to distal radial shaft and subluxation or dislocation of the distal radioulnar joint (DRUJ)
Galeazzi fracture
What is a “reverse colles fracture”
A smith fracture
Smith= volar displacement
What percentage of patients with a calcaneal fracture will have an associated vertebral compression fracture?
