Lacerations of the finger can bleed quite profusely because of digital vascularity. This obscures the provider’s ability to perform a careful exam and can make suturing quite difficult. Simple direct pressure over the laceration often controls the bleeding.
What if this doesn’t work?
A middle-age woman presents to the Emergency Department with altered mental status after having ingested a drug. Is it an opioid? Is it an antihistamine?
The key is to pay close attention to the vital signs. They are often the clue to the mystery. I found this great table from EM Clinics of North America by Dr. Timothy Erickson from 2007. I can’t imagine how long it took for him to create all these mnemonics. I’ll never remember these mnemonics, but they’re fun to read nonetheless.

Ingrown toenails, or paronychias, are usually exquisitely painful and a bit gnarly when they present to you in the Emergency Department. Dr. Stella Yiu described toenail splinting techniques using steristrips or dental floss. The purpose of splinting is to prevent the toenail from growing back into the lateral nail fold.
This assumes a relatively mild-to-moderate case. Often simple elevation of the nail out of the lateral nail fold (under digital block anesthesia) is all that is needed to treat a paronychia. Pus is often released with this maneuver.
There’s no toenail to slide the steristrip/ cotton/ dental floss material under.
Wait, what?!
What a terribly written test question!
Emergency physicians are procedural experts in central venous access. The subclavian vein is the best site for such access, because it has been shown to have the lowest rate of iatrogenic infections and deep venous clots
Bedside ultrasonography has really revolutionized how we obtain vascular access over the past 10 years. Identifying the subclavian vein using ultrasonography, however, is still technically challenging. The vein is located just posterior to the clavicle, which often gets in the way of the linear transducer.
It is difficult to determine if a patient with a left bundle branch block (LBBB) has an acute myocardial infarction (AMI) because ST segments are “appropriately discordant” with the terminal portion of the QRS. That means if the QRS complex is negative (or downgoing), the ST segment normally will be positive (or elevated). Similarly if the QRS complex is positive (or upgoing), the ST segment will be negative (or depressed).
In 1996, Sgarbossa et al looked through the GUSTO-1 trial patients with LBBB and AMI. They derived 3 criteria which may help diagnose the “hidden” AMI. The criteria are:
1. ST elevation ≥ 1 mm concordant with QRS complex (most predictive of AMI of the 3 criteria)
2. ST depression ≥ 1 mm in lead V1, V2, or V3
3. ST elevation ≥ 5 mm where discordant with QRS complex
Use these criteria with caution though. None of these criteria are perfect. They are to help you risk-stratify. For instance, criteria #3 (ST elevation ≥ 5 mm) can exist in asymptomatic patients with LBBB because of concurrent left ventricular hypertrophy and high voltages.
I often get asked by my advisees: “In my residency interview, what should I talk about or do to make myself more competitive?”
To help you demystify the interview process, I wanted to share with you some insights. Overall, the interview day itself helps the program put a person and personality with your online ERAS application. Similarly, you quickly get a sense of the program’s personality. In EM, the residency interview day is generally pretty laid back. Not too many crazy questions. Programs just want to get to know you. Both you and the program should be asking each other– Is this a good fit?
