all about ectopic pregnancy according to Tintinalli (textbook)
problematic d/t the fact that this is a leading cause of maternal death particularly in the first trimester. risk factors are anything that perturb the fallopian tubes (previous ectopic pregnancy, assisted reproduction techniques, PID, prior tubal surgery, IUD use, in utero diethylstillbesterol exposure). classic triad of symptoms includes pain (abdominal/pelvic?), vaginal bleeding or spotting in a woman w/ amenorrhea (this triad is more common in spontaneous or threatened abortion than in ectopic pregnancy). consider ectopic pregnancy in any woman presenting w/ abdominal/pelvic pain in any woman w/ unexplained ssx of hypovolemia (ectopic pregnancy is often diagnosed incidentally via US). may find adnexal tenderness, cervicitis (think gonorrhoea, chlamydia). Diagnosis typically made by US, other options include laparoscopy, surgery. contrary to my previously held belief, Bhcg levels cannot be used to predict an ectopic pregnancy from an intrauterine. the principle goal is to ensure that IUP is present (this was in bold), typically via US. If there is a clinical suspicion, do a transvaginal US regardless of what the Bhcg level is (ectopic can be present even if Bhcg is very low). surgery is required for cases that can only be diagnosed via laparoscopy. medical tx can be performed w/ MTX

approach to chest pain
rule out the high acuity stuff (i.e. STEMI) so order an EKG if the EKG shows STEMI, they go straight to the cath lab. if they don't havea STEMI move to biomarkers. if biomarkers (troponin) is positive they have an NSTEMI and go straigtht to cath lab,; if negative they have UA which gets a stress test which if positive requires cath lab

define sepsis, severe sepsis and septic shock
sepsis is two or more of the SIRS criteria plus infection; severe sepsis is sepsis plus organ damage or hypoperfusion (kidney failure, CNS changes, DIC, ARDS); septic shock is severe sepsis plus hypotension despite adequate fluid resuscitation (less than 60 systolic without pressors)
define sepsis, particularly how it differs from SIRS
sepsis meets at least two of the SIRS criteria and has an identifable source of infection
approach to severe HTN
severe HTN is that which has a SBP of at least 180 or a DBP of at least 110. pts w/ such as blood pressure need to be assessed for end organ damage as this is the feature that distinguishes the scenario from a HTN urgency from emergency
when assessing pain for severity, it is useless to ask about a scale of 1-10 without a reference. what are some good references to use?
severe pain occurs in kidney stones, delivery of a baby, bony fracture (i had kidney stone in mind, i keep forgetting how severe bone pain is so this also holds utility when inquiring about trauma and suspected fracture)
what differentiates severe sepsis from septic shock?
severe sepsis is responsive to fluid, septic shock is not
in evaluating a patient for chest pain, it is important to rule in/out ACS. what is the utility in asking about that quality of the chest pain (more specifically, what is the utility in knowing if the chest pain is sharp versus dull)?

sitting and leaning forward; ST elevation in all precordial leads, normal cardiac enzymes
pericarditis chest pain is typically relieved by positional changes... which position?

name one characteristic of fungal rashes
tend to cause some sort of scaling
tell me everything that you know about hypertrophic cardiomyopathy
tends to occur in young patients (late teens) and is a sudden cause of death. alternatively, may cause SOB d/t obstructed LV outflow tract, which sounds like aortic stenosis (thus aortic stenosis on a young patient is hypertrophic cardiomyopathy until proven otherwise). diagnosis made w/ ECHO, tx w/ BB to increase preload

that is atypical for a stroke and suggests an alternate diagnosis
The most common intracranial aneurysm is a saccular or berry aneurysm and located where? Treated with surgical clipping
the circle of Willis or its major branches
everything about epiglotitis (according to Tintinalli text)
the kid will look anxious, tripod position, may be drooling, will not be coughing (this may differentiate it from Croup, diphtheria). it is acceptable to try to view the epiglotits (some people will say don't do think b/c it can injure them but threres no data to support this claim). get an xray to check for thumbprint sign (the white part of the xray will look like a thumb), if this is negative but clinical suspicion remains can directly visualize the epiglotis. airway management is the most important thing, put the kid in an upright position, give oxygen, nebulized racemic epi, intubate, second or third generation cephalosporin (cefuroxime, ceftriaxone) for 7-10 days, steroids
utility of abx in pneumothorax
there is none. don't use abx. i say this because I was unsure as to whether or not they were indicated, they're not.
tell me everything that you know about non-anginal, atypical and typical angina
these definitions hinge on three ssx: 1. left sided chest pain 2. brought about w/ activity 3. relieved (not necessarily resolved) by rest and NTG presence of all three is typical angina; 2/3 is atypical angina; less than 2 is non-anginal
pt presenting w/ CP is asked if they have a hx of migraines and/or Raynaud's... why?

third generation cephalosporin (ceftriaxone) and a macrolide (azithromycin). alternatively, can go w/ a fluoroquinolone (moxifloxacin)
everything about how to place a chest tube
this goes in around the 4th or 5th intercostal space, midaxillary line; i've only ever seen em' placed in the right side which suggests to me that the right lung is more commonly affected in the case of a pneumothorax. gotta use the sterile technique, so clean the target area, drape, gown up and be sure to wear a face shield b/c this procedure will have airborne blood. inject copious local anesthetic (one doc said that you can't possibly use too much), go pretty deep b/c you want to get to pleural space, make a small incision (~1.5") around the fifth intercostal space going through epidermis, through the subcutaneous fat, down to through fascia then use finger to go the whole way through into the pleural space, dig around in there to clear the way for the tube. place the chest tube directing it towards patient's head until it stops (like to elicit an "ouch"). before placing the tube, you want to place it directly above the rib (the intercostal nerves run below the rib). tie tube down w/ sutures, hook it up to the wound vac, take an Xray (chest tube has radiopaque substance)
a learning scenario: 17mo male w/ hx of asthma presents to ED w/ very labored breathing; tachypnic w/ use of abdominal muscles. Intermittent crying before passing out, oxygen sat 78%. Respiratory therapy was consulted, started racemic epinephrine (no wheezes heard therefore didn't do albuterol b/c that only works on lower airway--always figure out if respiratory issue is upper or lower airway). cbc demonstrated leukocytosis leukocytosis of 34, upper respiratory xray (ordered for suspicion of croup, alternatively epiglottitis) revealed RML PNA. pt was afebrile
this goes to say that WBC level may have some correlation w/ the severity of PNA and may thus impact presentation. the fact that this kid was afebrile raises concern for sepsis (commit to memory that criteria for sepsis is high or low temp). also ordered venous blood gas which revealed metabolic acidosis (low pH, low bicarb) which is kind of bad news bears as it can result in coma and death.
definitive tx for Torsades
this is a polymorphic Vtach which needs to be tx'd w/ a pacer
approach to sinus tachycardia
this is a scary arrhythmia b/c it cannot be shocked (if you shock em' you will kill em'), so you need to think about why they have it, which can be problematic. this could be d/t a PE (most common presenting sign of a PE is sinus tach), volume depletion, hemorrhage to name a few.
fun fact about DOE
this is a sign of minimally heart failure and occurs w/ left or right
what is the utility of pulmonary angiography in PE?
this is considered the gold standard for PE but it is more invasive and a spiral CT does a pretty good job of detection em', so if the spiral CT comes back negative but clinical suspicion remains high then consider pulmonary angiography
two things about general impression
this is important and should be the first thing that you consider to guide your diagnosis (i.e. patient has CP and looks toxic start thinking MI right away rather than asking about other things), get an idea for age because elderly patients may have an abnormal presentation
Briefly define the pathophys of an elevation in cardiac biomarkers
this is indicative of infarction (i wonder about ischemia)
how is acetaminophen poisoning diagnosed?
this is my guess but likely based on the HPI. also check LFTs in which case the AST may be over 1000 (that part is fact)
word of caution for interpretting QT prolongation
this is rate dependent and can thus be masked. algorithms exist to check for it and if i recall correctly this is the corrected QT. this all goes to say that you need to keep a high index of suspicion especially for tachycardia or anything close to it
what is the Centor criteria? What is it good for?
this is used to predict whether or not a sore throat is bacterial in origin, has a terrible positive predictive value (thus if they have these things you should still order a rapid strep to be sure) but a good negative predictive value (thus if they don't have these things they probably do not have strep) criteria includes hx of fever, absence of cough, tonsilar exudate (exudate is not the same is ulcers), anterior cervicular lymphadenopathy
all about ARDS
this looks a lot like CHF--SOB, low oxygen sat, crackles on lungs. this is giong to occur in patients that are sick w/ something serious such as sepsis or some other major insult such as nearly drowning. get a CXR which demonstrates fluid. PCWP will be normal (around 10) but realistically don't need to check this, instead get BNP and echo both of which will be normal which differentiates it from CHF. tx is aimed at resolving the underlying etiology, need to get oxygen sat up using PEEP
pt involved in a MVC comes to ED; hypotensive, afebrile, you notice JVD and hear muffled heart sounds... what do you need to do next?
this sounds a lot like a cardiac tamponade (Beck's triad of hypotension, muffled heart sounds, JVD; typically accompanied by a hx of trauma). next step is to get an echo
two indications for CABG
three vessel dz, left main artery dz
kawasaki disease Dx
thrombocytosis elevated ESR note: seen in 2nd week
utiliity of head CT in pt suspected of having a stroke
to check for things that would contraindicate tPA use such as tumors, bleeds, aneurysms... it's role is not to rule in a stroke as many cannot be seen on CT, thus diagnosis is more so clinical
definitive tx for cardiomyopathy
transplant, but this is unrealistic. point being that this is a terminal condition
What are some drugs associated with Torsades de pointes?
tricyclic antidepressants, erythromycin, ketoconazole, haloperidol, cisapride, disopyramide, pentamidine, sotalol, class I anti-arrhythmics
approach to chest injury
try to get a feel for the force of impact. need to consider the lungs--pneumothorax, contusion, hemothorax, and the heart--pericardial effusion, and the great vessels--aortic dissection (most common in high speed MVC)
this is a oncologicla emergency and thus you should put it on your ddx for any chemo patient
tumor lysis syndrome
tell me everything you know about Prinzmetal angina

visual acuity (not actually practical in her case, but i say this to emphasize that it must be documented on each patient presenting w/ eye pain). also do a slit lamp. HPI of contact lenses in overnight suggests keratitis
traditionally the leading etiological agent of epiglotitis but thanks to modern medicine there's a vaccine against it
was Haemophilus influenza, but now there's an HIB vaccine and now other causes are Staph and Strep

whether or not the patient is stable (which probably is true for all scenarios); altered MS, hypotension, cardiac symptoms of ischemia (anginal CP) if pt is unstable get a 12 lead ECG and first check if it's a narrow or wide QRS, regular or irregular (most common irregular is afib)
pt complains of blood coming out of mouth (i.e. hemoptysis). what's the first thing that you need to consider
whether this is truly hemptysis i.e. coughing up blood, rather than throwing up blood
a note about back pain
