11/8/21 Early Bird Flashcards
High-quality chest compressions are associated with CO2 values of?
CO2 values > 10 mm Hg
The value of CO2 is also helpful in prognostication of the arrest. For patients with a value of at least 10 mm Hg, the chance of return of spontaneous circulation (ROSC) is greater than 90%. Those with less than 10 mm Hg are almost never successfully resuscitated.
What is the current recommendation for targeted temperature management?
The patient should be cooled to a goal of 32–36°C
What diagnostic test can help identify right coronary artery vs. left circumflex artery involvement in an acute inferior wall myocardial infarction?
Right-sided electrocardiogram with a focus on V4R.
An upright T wave in lead V4R indicates involvement of the distal right coronary artery, and ST segment elevation indicates a proximal right coronary artery lesion.
Inferior ST Elevation Myocardial Infarction
RCA occlusion
ST elevations: II,III, aVF
RV infarction
ST elevations: V4R and V5R
JVD, hypotension
Rx: IVF
NTG contraindicated
Why is the MMR vaccine administered at 12 months of age?
Measle, mumps, and rubella are rare among infants less than 1 year of age because of protection by maternal antibodies against these viruses.
Sarcoidosis Labs will show
hypercalcemia
elevated serum ACE
Glimepiride is what kind of medication
sulfonylurea
Cluster Headache Prophylaxis
verapamil
What is the most common pathogen associated with cholangitis?
E. coli (25–50%), followed by Klebsiella (15–20%) and Enterobacter (5–10%) species.
A torus fracture is also called a ?
Buckle Fracture
Axial compression
Wrinkling or buckling of cortex
Distal radius (most common)
Casting
Which odontoid fractures are considered unstable?
Type I (stable), Type II (unstable), Type III (unstable).
What is Hutchinson’s sign?
Vesicular lesions on the tip of the nose which are associated with a high risk of herpes zoster ophthalmicus.
The current recommended treatment for massive PE is thrombolytic therapy with TPA if any of the following criteria are met:
cardiac arrest
hypotension
respiratory failure–> pulse oximetry reading < 90% despite oxygen administration
evidence of right heart strain on cardiac ultrasound
elevated troponin levels.
What is the one absolute contraindication for transvenous pacemaker placement?
Mechanical tricuspid valve.
Postpartum Hemorrhage Management
Empty bladder
Bimanual exam and uterine massage
Oxytocin and additional uterotonics (e.g., prostaglandins)
Tamponade (balloon or surgery)
